PS4 Diagnose Faulty Panasonic MN86471A HDMI Encoder IC Chip Tutorial (WLOD)

[@chronic8660]

Man you the best!!! I always wanted to learn microsolder. My hdmi port broke on mine 1 year ago and i just so happen to run into 1 of ur videos and it was downhill from there. Ive bought 16 used PS4s so far and successfully repaired 10. Im looking forward to doing my first APU as soon as i can afford better tools. Im working with a cheap walmart solder gun and a $10 microscope i ordered from wish. My first 2 repairs were with a magnifying glass taped to my phone camera lol. Thanks Andrew

[@derekdegraan756]

I need this done to mine. I just recently dropped my ps4 off at the local repair guy to have fixed knowing that I had this same problem. When I explained the problem and my suspension of what it could be, I was reinsured it shouldn't be a problem to repair. Well guess what? Got a phone call letting me know they replaced the hdmi port only to have the same issues and they do not have a in house person to replace the i.c. and apparently there is not a person in the whole city of Austin that can fix this problem. So I guess I'm doing it myself. Thanks for the excellent video guide! I really would love to send it to you for repair..

[@davidbillington5401]

love the idea of soldering long pins or needles to the tester tips

[@nicks.789]

all of your videos are extremely helpful! I replaced my first hdmi port successfully the other day thanks to your vids. thank you for sharing your knowledge

[@AndrewPaul]

Thank you and congratulations on the successful repair :-)

[@thiagoleiteoliveira8468]

always say around here, that in the USA! it's always better to buy a new one than fix an old one! because of the facilities to buy electronics! already here in Brazil! we tie with wire! we put ribbons, we stick! or we make the most infinite exotic repairs, when we have no parts! I liked the way you are perfectionist in replacing the aligned resistors etc! well professional your work!

[@8uckshot]

Thanks for showing this. Now I know I don't have the tools or the patience for this. I'll leave this repair up to the professionals.

[@Infiniti25]

Would have been nice to capture the HDMI port testing on camera, although I suspect this is done this way intentionally so not to give away tricks of your business or because it's hard to get everything on camera AND the DMM. Glad you showed testing continuity of the video filters to the chip itself though, helped me verify my HDMI video filters as ok. I replaced my HDMI encoder chip and I now have video and sound...Many thanks for this and all your other content, you have shared and helped me and so many others, you do great things :)

[@MrCP]

Nicely done! Finally I can realize which is the problem with my PS4.

Fantastic job done highly confidently. Excellent teaching as well. Good on you. Thanks.

Thank you :-)

[@proconsoles_nl]

Andrew, your video's are great. You are definitely someone who never gives up, like that ! Just had a ps4 with WLOD and flikkering black screen at random times - under microscope I saw 1 pin moved about 1mm inside, so that one needed replacement - replaced HDMI port, same problem - replaced HDMI IC, same problem - gone through your video's, measured everything again, all GOOD, so eventually concluded that the NEW HDMI IC chip was defected - replaced HDMI IC by another new one, and BOOM, working ! Satisfied, but still thinking, how could that happen ? Never seen a new defective HDMI IC chip, did you ?

[@AndrewPaul]

Had one before now but only the one thankfully. Not bad going really in the circumstances lol :-) Really annoying though as it does leave you scratching your head for a while:-)

[@proconsoles_nl]

Andrew Paul Thinking about desoldering and soldering back the hdmi Ic's with my rework machine, which I use for reballing apu's for blod ps4's. Also Thinking about a test method to test new hdmi ic's, suspicious hdmi Ic on boards and desoldered hdmi ic's. When I desolder and solder back a hdmi Ic with my rework machine, i can make a video, if you like. I scratched my head actually all the time yesterday, when It did not work after replacing the Ic for the first time. Left my girlfriends house on sunday and said: I need to get back to work, I need to fix It.

[@Plan-C]

Thanks. You are very good at what you do and at explaining it to others. Keep it up. Thanks to you, I got a blue light of death (long version) off ebay going with the 3 washers trick only to find white light of death after that. I fixed it by watching your videos and changing the hdmi encoder. I second your comment about hot air stations. My trusty Aoyue 968A+ got the old hdmi port out (it fell out whilst taking the shield off the hdmi ic on the other side of the board lol) but could not get the board hot enough to allow for aligning the hdmi port pins with a new port. Thankfully, the old port was OK and the previous owner had given up at that stage. Cheers.

Hi i have a ps4 white light problem and need advice. So i traded a faulty xbox one original for a supposed faulty ps4 original from a person that fixes consoles that wanted the Xbox for spares. So on the day i got home with the ps4 i used my ps3 cables to power it on and it miraculously powered on which surprised me as the controller was connected properly using the usb cable. But i saw the screen flash black then back to the home screen which i didn't know what is was then it did it once more and was displaying perfectly. After about 5 mins of waiting for it too show some errors or switching off because i did not expect it to work i plugged in my usb speakers to the other usb port on the front while the controller was plugged in. That was when the screen went black instantly. I didn't know what happened and pressed the eject button and a copy of GTA 5 came out which means the console was still powered on. When i plug the controller and speakers in on my ps3 super slim at the same time is says too many devices drawing power something like that. So i think it drew too much power on the ps4 and caused a wlod on the ps4. Im trying to do a home repair with minimal tools and if you could give me some idea of what the usb ports could have shorted eg a transistor or fuses or something. It still powers on and everything but that was the defining factor i think that contributed to the white light of death. Any recommendations would help as ive watched a lot of KZbin videos and most are the ic chip or some transistor . Its a original ps4 with wlod 1116A

[@piotrnowak1302]

Great video! Keep on going mate! Now I'm going to fix PS4 that used to have some artifacts (screen goes red, and customer reporting also some sound problems which I didn't noticed) while playing games. What I think it can be faulty HDMI encoder IC. Hopefully the GPU is OK.

[@lynchpyn7805]

Thanks so much, you have helped me yet again! This is educational but I enjoy watching so much. I appreciate that you show the whole process rather than editing everything to make it more appealing to the masses. Keep the great content coming and thanks from Australia.

Hello! I would like to know if you replaced back the metal panel/heatsink(don't know if it was?) over the chip

[@zbrnelic]

nice video ... if 4 chokes are dead after power surge, are there any chances that IC survived ? can i just bypass chokes to test IC and then replace them if IC is OK ? i have this ps4 that died after power surge ... it was completly dead and after i have replaced power supply with ATX PS and now it has WLOD, cheking those chokes like you did shows all 4 chokes are dead ...

hi Andrew, i replace the IC and now i have a black screen but with sound, any suggesrtion?? i found the error, is the pin 6, I gaging in 20:02 and pin 6 does not give continuity, bypass or replacement? excuse my english but im from mexico

[@AndrewPaul]

So you have no continuity across the filter? Check it from the top of the filter to the bottom - if no continuity replace the filter. If there is, then check it from IC to filter and filter to via. When you find which side the break is run the appropriate link wire. Cheers.

[@luisdias6868]

Hello. I'm starting to learn, to repair things. I have a ps4 1116a, which does not give an image. I did as you explained, but even so, there is still no picture. I noticed that near the hdmi encoder, as you said, it has 4 components, all in a row. They seem to me to be capacitors and resistors, but I don't know. Can you tell if this affects anything, in not giving an image? The components are the ones you mentioned.

[@RainWalker24c]

Ill be doing this on my ps3 this weekend. I like the method you used for soldering the new chip on. Most seem to put the chip on bare traces(no solder), then put a big glob of solder or solder paste to one side & drag solder all the way around. May work but it looks easier in vids & its easy to mess up doing it that way imo.

[@pepperjack7870]

First testing from the pins to the alternates had me confused as I couldn’t really see what he was doing and my motherboard is completely different from that one. Would really like to test everything before I buy a new chip. Also what are you putting on the chip before removing it. And what temperatures are best for removing the chip. Mine didn’t have a cover over the chip and it’s directly behind the port on the same side.

[@gordenfraxby84]

Excellent video mate, I've just learnt so much from this 47 minutes. I've got just the board here to try all this out on too. Thanks again

Awesome video!! just passing trough this can I ask what was the air flow and heat you use aswell as the flux I'm practicing with other boards before doing this but my flow and flux aren't helping.

Could there be another issue to the no signal problem other than hdmi port and hdmi encoder ic chip? (How likely it's another issue other than this two?)

[@playstation2bigs]

Wazzup bro , My beloved 1st generation ps3 slim having a problem, it stuck at 480p at HDMI. I resolder the PS3 HDMI port and it not fix the problem, do you think it's the panasonic MN8647091 hdmi transmitter is the problem? it can't recognize 720p 1080i and 1080p stuck at 480p only. AV multi out is functioning normal.

[@AndrewPaul]

+playstation2bigs Hi mate - yes that's probably your issue.

[@playstation2bigs]

+Andrew Paul do you think it's a cold solder joint? or replace the whole i.c. ?

[@AndrewPaul]

+playstation2bigs It might be worth doing a drag soldering job on the IC to see if you can get rid of a cold joint or two but if it's anything like the MN86471A found in the PS4 then dropping of the HD resolutions indicate an internal fault and will require a replacement of the IC. Cheers.

[@mharkonnen]

Hi Andrew, I have replaced a HDMI transmitter chip, but for some reason only getting Sound output on the HDMI.... would you have any idea what would be next suspect? HDMI port looks fine, so i haven't replaced that yet.....

[@AndrewPaul]

Sound but no image is typically down to a bad encoder, however as you've just changed it I'd be more inclined to suspect a loose / bridged pin. Give them all the 'nudge' test with a tweezer blade and see if you can get any to move and resolder them if they do. If you've any shorts / bridges between pins then these will need to be removed. If that all looks good, check the EMI filters to ensure they're within spec.

[@mharkonnen]

@@AndrewPaul i did check all the pins, pretty sure there is no bridging or loose pins though i will check again once more just to be damn well certain ! I continuity tested the 4 filters, they all came out fine.... just like how you did it in this video. Pretty stumped to be honest, the sounds on but no ones home ! lol.

Andrew, Wonderful video. I am hoping you might give me an idea as to the next step for me. I replaced a damaged HDMI Port and all the pins test well to the IC and to the test connection points on the board. When I put it all back together I got the WLOD. I went into safe mode and found that the unit displays well in 480P , but it doesn't want to work with any higher resolution. Does this still sound like an encoder chip problem to you? I will replace it if needed, I just didn't want to order one in before I exhaust all options. Thank you for any input.

Hello Andrew, I have a WLOD ps3 with no sceen output, safe mode not possible. Replaced the HDMI IC chip and after that the screen output was a noisy red. And when I moved the hdmi cable (good one) the screen went intermittently from red to nothing, so I also replaced the HDMI port. Now the screen output is constantly noisy red. Tested the 4 video filters next to the HDMI IC and they are all good. HDMI port pinout is good (checked your other video). Also the connection of the 8 points (video filter points) with top and bottom mobo are good. What do you think is the problem here ?

[@AndrewPaul]

+ProConsoles Was the IC a known good part? Is it possible to test it on another board?

[@proconsoles_nl]

+Andrew Paul It was a brand new one actually. But I do have a scrap board with a good one on it. Can desolder that one and use it for this board. Can't stand this, it has not been fixed. After diner I will continue and finish this ps4. Tomorrow the customer flies back home in the US. I soldered on the HDMI with drag soldering with JBC soldering iron on 365C. Need to find out test points first. Besides thanks a lot for your very fast response ! :-)

[@AndrewPaul]

No problem, and please let me know how you go :)

[@proconsoles_nl]

+Andrew Paul Replaced the HDMI IC chip, by a HDMI IC chip I desoldered from a scrap board and ....... again no screen output. Somehow this HDMI chip was not good, I hope and suppose. Tomorrow I will take again, a new HDMI IC chip and post the results. I like to mention that I desolder the HDMI IC chip somehow different, then how you do it. I use low melt solder to lower the melting point from 217C to 150C, then use hot air to desolder the IC chip. I think it is a little bit more safe. Do not want to damage the surrounding components.

[@proconsoles_nl]

+ProConsoles Soldered in a new HDMI IC and still the same problem. Pin 13 of HDMI connector does not have a low resistence. All connections from end of HDMI cable to the test points are good, video filters are good. Nothing of the soldered connections have shorts. Still WLOD without screen output.

[@TheVdub1980]

I love watching your videos. Just wondered what flux and solder you use? My de-soldering braid seems to solder itself to the point I'm de-soldering so thought it maybe my flux?

[@AndrewPaul]

Flux is Amtech NC-559. Solder is just a generic 60/40 tin/lead with Rosin core flux.

[@onebyone022]

I dont know if i recieve a faulty replacement, but before theres was continuity betwen in the 4 filters, i mean each pin of them. So i took off the ic and the short was gone. So i solder the replacement and theres continuity in the 3rd filter. Thats normal? Can you tell me if i have a faulty replacement? Thanks

[@AndrewPaul]

Sounds like you either have a small bridge between the pins (they can bridge to the rear and are hard to spot without a scope) or a faulty replacement.

I desolder it again and clean it. Still there (in the ic) so I guess its a faulty one...

[@AndrewPaul]

You'll need a Panasonic MN86471A for a 1003A. The metal shield can be left off if you're struggling , but to place it back you'll need to re-solder it back using a fairly large iron tip and flux.

[@ChesleyMcDaniel]

What temperature do you have your soldering iron set to for applying the leaded solder to the pads?

[@AndrewPaul]

+Chesley McDaniel It's self-regulating so I have no control over it. The iron calculates the needed temperature by measuring the heat draw across the tip when touched to place where the joint is required - so I don't know what temperature it's using. Cheers.

[@ChesleyMcDaniel]

+Andrew Paul Oh okay, fancy! :) Thanks anyways.

[@AndrewPaul]

+Chesley McDaniel No probs - however, my TP9 tip has blown this last week and I'm waiting for a replacement so I'm back using my old solder station for now for fine work. To drag solder effectively that station has to be set to 485 Celsius.

[@ChesleyMcDaniel]

+Andrew Paul Thank you for that. I wouldn't have expected it would need to be that hot. Now I see why I was having trouble. My iron only reaches 450 Celsius but I was afraid to turn it up that much out of fear that it might fry the HDMI chip. Have been having hell with my ps4, pulled a pad where the Panasonic HDMI chip mounts (due to having a much to large hot air gun and being afraid of burning up the MOBO), so I attached a very small jumper wire to the proper circuit but still have WLOD. Now after several attempts, I broke off a leg on the Panasonic chip where I had the jumper wire.

Hey man, my ps4 was working fine today but in the middle of playing a game, the screen went black but the system was still on. I couldn't get a signal anymore and tried a different hdmi in 2 other TV's and it didn't recognize that there was a signal at all. My computer also plugged into the same wall socket doesn't show video now either. Is there a way to fix the ps4's video signal, it still turns on and shows the white light but no video

[@guitarkid2184]

Also do you think it was some sort of the surge because it smelled like something had heated up and started melting, plastic maybe

[@AndrewPaul]

+GuitarKid218 Hi, yes sounds like a bad one. If it's done both your computer and your PS4 then it sounds like a rather nasty power surge. I'd get the wall socket checked by an electrician to be sure it's not localised to that one socket - always best to be safe rather than sorry in these instances, especially when dealing with mains voltages. Anyway - as far as the PS4 goes it's probably frazzled the HDMI Encoder IC or part of the circuit which it controls. If you're not familiar with troubleshooting these things then it's probably going to be a bit tricky and would probably be best suited to a pro console technician who knows a bit about component-level repair. Good luck!

[@nazeffex8229]

Hi Andrew great video followed your video's and decided with your guide to change Panasonic IC chip but regrettably as everything was going so well, after removing the IC chip I noticed the four filters have come off. What's the best way to put them back on or am I screwed? :-( Thanks

[@AndrewPaul]

+Naz Nadeem just pop them back on - they're not directional so just line them up back on their pads, hold them with some tweezers while they reattach. Once they're all back on turn the airflow down a bit, add flux and reflow. They'll all line back up perfectly and you should hopefully be good to go!

scrap boards are the best bet - PS3s have the same filters and scrap PS3 boards are pennies on eBay so just drop for one of these and swap them back over - you'll have a few spare then too :)

[@TaaRiiFrp]

i have got one ps4 with distorted display i resoldered the hdmi pins. now its a bit batter but still little distortion after few seconds but nothing happens when move the cable. distortion is tiny bit after few seconds with a little distorted sound. should i just follow everything from start to end or just change the hdmi i?. i have a doner board on me to get hdmi ic from.

[@AndrewPaul]

+TaaRiiFrp Check to ensure the HDMI comb isn't out of shape - they can warp slightly which can cause intermittent issues like you describe. To be sure you can check connectivity of each pin with a multimeter. if all looks good and you've got a spare IC then give it a try and see what happens :)

[@TaaRiiFrp]

+Andrew Paul thanks for replying mate, i actually follow all steps but hdmi comb as i don't have the diagram for that and eventually changed the hdmi ic from a doner board and it all works fine now. can you provide the hdmi comb's ways? and how do we differentiate the if it is a graphics card problem or hdmi ic problem as both problems resulted in corrupt and distorted display?

[@AndrewPaul]

+TaaRiiFrp The comb is just the plastic tab inside the HDMI port - you can't change this on it's own - you'd have to change the port but happily you don't have to do that now. It's very easy to differentiate between an APU failure and a HDMI Encoder IC issue. An encoder IC issue will cause one or a combination of static, an over-saturation of one particular colour, the loss of a particular resolution, or several resolutions / blank screen with no audio, solid red/green/blue screen with no audio etc. APU failure will cause the console to display as normal however the image will start to drop detail and cause glyphs / malformed polygons etc. This will get worse very quickly before the machine would lock / power off.

[@TaaRiiFrp]

+Andrew Paul appreciate it, cheers mate.

[@Dgenr]

Hey Paul good day. I have a ps4 which I'm trying to repair, pins 1 to 12 all show low resistance to the ground, it's like they are all connected, multi meter bins no matter which pin I touch from 1-12, 13 -19 are ok, have you ever come across such?

[@AndrewPaul]

Remove the encoder IC then recheck continuity to ground. If it disappears, replace the encoder IC. I'd also check the EMI filters in such instances as these might also be damaged - sounds like that console has taken a fairly hefty whack with a decent amount of current back through the port.

[@Dgenr]

Yes, the owner said that the flat screen TV shorted out. And after that the console never was able to output any video signal

[@Dgenr]

Mr Paul. I took your advice , I removed the ic and the short was gone, the tv recieves signal from the console now but the signal is in DVI, tried many options. None of them worked, is there anything you can recommend?

One question My PS4 when running the screen is black console light White and on screen unknown input

[@varunprasad7299]

Hi Andrew, I'm new to repairing but I've taken on the challenge of repairing a PS4 original, I found (SAB-001 model). Tested the HDMI pins and pins 1-12 (all the data pins) are shorting to ground. Is this normal? Everything else around it looks fine. The IC encoder side had some sticky residue on it so is this likely a bad IC? Thank you so much for the video! It's been amazingly useful! Keep up the excellent explanations!

[@Denden010]

Nice vid mate, I have question: My ps4 goes on into a white light, so no image. When i go into safe mode, it gives a screen for 1 second and after that the screen goes black again. I have replaced the hdmi port, but no succes. Do you think it might be the Retimer on this board? Thanks in advance

[@nicco-54]

First of all thank u for your help. Sadly i have another doubt. Checking on the internet for the Panasonic chip MN86471A i found out that there are lots of models with various prices of the same chip. May you tell me whats the difference ? Quality of the component? it seem strange because every chip is sold by panasonic. Of course im not an expert , thanks for your support.

[@AndrewPaul]

It's just re-sellers trying to maximise profits on the parts as seems to be common these days sadly so prices naturally fluctuate wildly. Go for the cheapest reliably rated seller you can find.

[@nicco-54]

Thank you so much!!

[@AndrewPaul]

You're welcome. :-)

[@phoenixtiger101tube]

Hi Niccolò Im from Italy too. I would to do the same repair on my old ps3 slim but i'm a noo so I need some advices. Could you help me? If yes, could you share an email address / honagout to have a chat someday? Thanks a lot

[@antonioloro435]

hello sir, where i could buy a good one encoder chip? because i bought one in china thru online its not working after i put the chip the video does not appear. pls. helpme sir...

[@victorclausson4039]

I have a similar problem but the PS4 outputs audio but no picture. The HDMI port looked fine so could it be the HDMI transmitter in my case?

[@AndrewPaul]

Hi, indeed it could - the Encoder IC is responsible for muxing audio and video signals so this can be a sign of a failing Encoder.

[@victorclausson4039]

+Andrew Paul Cheers! Thanks for the tips and all your great repair videos. Maybe I'll come back asking what could be wrong when I've tried everything ;)

[@stevieselvey1407]

Check to see if pin 4 of the HDMI is short to ground (Usually the case of the IC short with no picture but have sound)

[@victorclausson4039]

Thanks for the tip, Stevie! Since I wrote my first comment I've replaced the HDMI port and HDMI Encoder. Still no picture. All the legs I've soldered looks great and have good connection, no loose legs, no shorts between legs, but still no picture. Although I haven't tried what you said and measure pin 4 on the HDMI port to ground. I'll try that tomorrow. BUT, today when everything was finished I tested it. No picture, tried safe mode (holding for the 2:nd beep), still no picture. Then I just left it with WLOD. Turned it off and on again and I got the PS logo and a blue screen with a lot of text in different language I think and some pictures of what the Dualshock 4 buttons do. Then the picture just disappeard and I haven't managed to get a picture again. I didn't touch anyting I just left it booting on my desk, sitting back watching. Thing to keep in mind! I'm using a PC monitor for testing so I can't hear no sound for the moment. The maximum resolution is something like 1600x1200 so could that be a problem getting a picture even in safe mode (480p)? I should be able to get some picture in safe mode, right? I don't have a controller so I'm just testing it with the power button on the console. Would I be able to do someting different to test with a controller?

[@stevieselvey1407]

Have you tested continuity from the upper part of the HDMI pins to all relevant points? Test the system on a TV to make sure too :) Sounds like at least one of your solder connections is not quite right. Do you have a microscope?

[@wrxsubaru02]

Dude, remember me? So I seem to still be having the problem but it hardly ever happens during game play since I changed out the thermal grease but it does still randomly happen... I noticed that if I move the ps4 while its plugged in and powered on, it almost always gets the WLOD causing it to freeze so I think there is some kind of short going on because if i squeeze on the right side of the ps4 it freezes it instantly every time and I get the WLOD. What do you think the problem is?

[@wrxsubaru02]

I purchased a new HDMI port but I haven't replaced it yet because I want to be sure of the problem since the symptoms kind of strange compared to others out there.

[@AndrewPaul]

Squeezing the right side would suggest APU issues.

[@wrxsubaru02]

I had a feeling it could be that but at the same time i wondered if it was a short or bad connection... I guess i will have to do a little more investigating. i noticed if i moved the hdmi it would short out too if i tapped it just a little

[@QsTechService1]

Looks like you have schematics And board view for The PS4 I've been looking for yours how old do I come across them ? ? I know they fall out for truck lol but how can I come across? them

[@AndrewPaul]

Hi, Sadly I don't, they're securely tucked away in Sony's repair centres. I wish we did have them though - it'd make repairing the more tricky issues a lot, lot easier!

[@QsTechService1]

Andrew Paul Thanks for the reply Andrew For Years I wish I had them Yes you're right it would make repair so much easier.. By the way good videos 😀👍

[@cyril8507]

hi Andrew , i removed accidentally 2 of the 4 caps (ferrite diode) near the panasonic chip when i putted the heat gun , they are damaged, so can i make a direct link between the 2 point of them?

[@AndrewPaul]

+Lena-Payette -et-cie Hi, if you can't source replacements then yes you can just bridge them with wire. Cheers.

[@fatken53]

Where did you dig up the board schematics for the PS4? We've had luck finding PS3, but not ps4

[@AndrewPaul]

+Ken Lerdahl in short mate there isn't any - well there will be but they're safely tucked away inside Sony's repair centre vaults. This is all from my own work and deduction. Cheers.

[@mmoneeb1]

Hi mate recently had a lightning strike on my satellite dish which was connected to my TV and the ps4 was connected to the TV via hdmi. Since that happened my ps4 has had the white light and cant get it into boot mode also all the hdmi ports on my TV are also not working. Just wondering what your input is. Do you think its the IC Chip?

[@mmoneeb1]

*Safe mode not boot mode

[@AndrewPaul]

Very possibly - there's no protection for it and it's the first thing in line once that surge hits through the HDMI port. Good luck.

[@mmoneeb1]

+Andrew Paul cheers mate, appreciate it. How much would you usually charge for a chip set repair??

[@shakimlesporis9083]

Could you replay to me and tell me what tools would i need to do this myself

[@_MJ07_]

Im pretty new to this, have been doing small repairs here and there, and have practised a bit on other boards ive had lying around. Decided to bring it to my ps4, and Im really struggling to remove my IC. The max temp of my hot air station is 450 degrees. Could this be the problem? Ive not had an issue removing anything before this.

[@AndrewPaul]

450C should be more than enough to be fair. The likelihood is the calibration of the air station temperature probe - which station are you using?

[@_MJ07_]

Andrew Paul I figured it out, I was just being a bit scared to use a higher air flow. Went ahead with the repair yesterday on a console that was just displaying noise y "snow" patterns. Now the console isn't displaying anything. I don't see any bridges on any of the legs, and the pads looked fine upon removal. Recon the new IC is dead? Also, I tested some of the legs on my multi meter in continuity mode, and they do have a connection, but they're not bridged from what I see. Is this normal? Sorry for the questions, thanks for your time.

[@getagriptv6718]

PS4 came in with badly damaged hdmi port, replaced the hdmi port . Tested it, video output was working going in and out. I replaced the chip brand-new and still no Video any ideas ? Also here is a photo asappcfix.com/pix/20190105_020128_001.jpg that shows pins that short to Ground when chip is installed. I removed a few caps but short stays. Short goes away when i remove the chip...

[@AndrewPaul]

Be careful with this one - what resistance is the DMM showing when measuring these points? They typically measure between 50-90ohms which most meters will beep for in continuity mode but isn't necessarily an indication of a short - merely that there is a low resistance between those points. Have you tested continuity of the EMI filters and ensured there are no loose pins on the encoder with the nudge test at all yet?

[@getagriptv6718]

it is 48.7 M-ohms that is from the Ground to those points

[@getagriptv6718]

filters are good tested parallel and cross did nudge test for ic chip and tested hdmi connection 3 times now just to be sure

[@getagriptv6718]

i also checked the diode for short to ground (pin 13) and the resistor to the very left of it in diode mode and i get get nothing should i change it?

[@tomasdittrich6384]

Is it necessary to put the HDMI IC shield back once I'm finished working on the IC, does it actually have any major role there. I didn't notice anywhere in your videos you putting it back. Thanks

[@Me_preppy]

17:05 he says "it's gonna be refitted" so yeah , put it back on

[@grahamkennedy7395]

Hi pal great video I’ve just replaced a hdmi port and it’s just white light no image on the tv I’ve gone through your steps and found the 2nd and 3rd filter by the control chip doesn’t have any continuity so I’m guessing replace those and hopefully will work

[@HackingVision]

Did you manage to get this issue fixed I have a PS4 here with similar issues swapped hdmi port and also IC from a scrap board i don't think the issue on this one is the IC but wanted to do it anyways for practice. I have not tested the filters yet as have not got fine enough multimeter probes yet just borrowed some that may be pointed enough going to test the filters tonight thanks for the videos Andrew very educational

[@someshegirl4002]

i have problem with signal it show 576p and picture like snow..what do u think it be..enconder ic??i already put out all filtter..but same problem..what do u think andrew?

[@AndrewPaul]

Yes most probably the Encoder IC in your instance.

[@someshegirl4002]

thank andrew..i try change that ic..waiting part..i update u later..u have email andrew?

[@AndrewPaul]

No public email but I can be reached on here or via Twitter DM.

[@someshegirl4002]

can u explain to me pin out for filter..it ok if pin 1and 7 and 10 have continuity?

[@AndrewPaul]

No - if you have those 3 pins shorted, remove the Encoder IC then re-test - are they still shorted? if not, replace the IC for sure.

[@netrixchile1]

hello I had a console without panasonic and partia with white light I installed the ic and now the blue light remains flashing intermintente

[@pezu20]

Hello Andrew Paul, I have a PS4 that does not display image on screen. I changed the HDMI port for a new one of more quality, but still no image. However, the TV detects the HDMI signal. Even when I restart the video parameters of the PS4 (pressing 9 seconds the power button), the image is displayed 1 or 2 seconds, but immediately the signal is lost again. Do you think this could be a problem with the Panasonic Chip? I hope you can help me. Thank you

[@AndrewPaul]

+Ernesto Fernández I'll more or less guarantee its the IC providing the new port has no loose pins or bridges.

[@pezu20]

Thanks for your quick response!! I want to emphasize that I have been able to see the image on the screen for a few seconds but the signal is lost immediately. Knowing this, you can ensure that the HDMI port is well installed, right? I would not want to buy the IC chip at all.

[@AndrewPaul]

I'd be tempted in that case to purchase a faulty board (i.e. BLOD) and then you have all the parts necessary. The few times I've seen them do this specifically I've ended up changing the big capacitors and transistor packages to the rear of the IC - some of those also required a new IC afterwards. If you have the donor board to hand then you have all the parts for every eventuality.

[@pezu20]

Agree Andrew Paul! I think I'll follow your directions! I'll tell you how I was. Thank you very much

[@pezu20]

The truth is that I do not have much knowledge of electronics. I think I would not be able to change all transistor packets. Have you had to do it many times? Or, usually just changing the IC chip has worked?

[@DhalonTech]

Where to find those at good price?

[@lord.frosty]

Hello Andrew. Very nice and educational video. I have a question. My PS4 boots and i get a white light too. Thing is, my TV does not recognize the device. It's like i don't have any device connected at all. But my ps4 boots normally. And i know this because i have it connected with optical output to my speaker setup, and i hear the booting sounds and the music from the menu just fine. So the ps4 is open and operational, but i get no signal at all. I opened it and hdmi port seemed fine. The encoder chip was replaced by a techinician at the end of April, but seems like the problem showed up again. Could it be that the encoder chip failed again? Could it be that the connection didn't last and probably just need some more soldering? The technician closed the encoder chip with the metallic cover so i have to open this first to check it out. And for this, i need to buy the equipment you use (heat gun mostly as i have the other stuff). Would i be sure that it is encoder chip's fault and not something else? I have no problem trying to fix it, but i want to make sure that this repeat in the future and i have a faulty encoder chip every 1 and half month. PS. Sorry for the long post. Hope you can help me. Of fource i checked my ps4 with multiple monitors and cables, problem still persists. Just to clear things out :)

[@AndrewPaul]

It could be a faulty Encoder or a bad port / lead. the fact you still have audio is weird. I'm not saying the Encoder cannot fail in this manner (it can) but I've seen it literally just the once out of who knows how many of these I've done by now. They normally fail entirely with the loss of both picture and audio. Much more likely will either be a bad HDMI lead or a loose / pushed back pin in the HDMI port. Give the port a visual check and see if any pins are pushed back / out or are sitting proud of the centre plastic comb. I'd imagine the original repair will be under some form of guarantee? Will the shop not take a look and confirm the issue for you if you ask them?

[@lord.frosty]

Andrew Paul About the first paragraph, is it possible that the audio transmitted via optical output is processed through a different chip on the board? And the ic encoder chip is only responsible for the audio output of hdmi? The shop does not accept my ps4 for guarantee since I tried to open it. Why would I open it if it worked correctly in the first place? Seems like something went wrong with their repair. Can you explain what exactly do you mean by hdmi lead? Thank you for your time.

[@AndrewPaul]

Ah OK - Optical audio comes from Southbridge so that explains that. If the port still appears physically OK then I'd guess it's another failed encoder. If you haven't already, change the HDMI lead when you repair it again as it could be a lead issue which is causing the chip to fail.

[@lord.frosty]

I see. When you are saying hdmi lead, you mean the hdmi cable?

[@herrdered]

Hi Andrew! Thanks for the vid. I measured the path from the chip to the filters and figured out that all pins going to the HDMI are shortened to ground. There is no physical damage on the port. I am consider changing the chip. What do you think? Regards, Erwin

[@AndrewPaul]

I'd bet that's a very good possibility. Remove the current IC and see if the shorts disappear. If they do, change the IC.

[@herrdered]

Thanks Andrew! I changed the HDMI IC and the shorts disappeared. As the metal shield around the chip was very hard to remove, I cut it away. Therefore, I tested the PS4 without the metal shield on the HDMI chip. The TV is getting a signal now, but still there is no picture. You can observe some noise (similar to the noise of an analog TV receiver) when the TV is getting the HDMI signal, before the TV is turning black. So, my main question is: Also without the metal shield, I should get a better signal, shouldn’t I? (I want to avoid placing the metal shield there again, it was a pain removing it already 😊 ) Regards,Erwin

[@audiogear474]

When removing I accidently blew off a component. It's to left then toward middle center of IC pins. Can you please identify. Can't find it anywhere. Thanks

[@AndrewPaul]

Have you a photo please?

[@audiogear474]

I can do one where do I send?

[@AndrewPaul]

Upload it to imgur.com and paste the link in below. Cheers.

[@audiogear474]

If you start at top left of IC and go down 13 pins that's it.

[@AndrewPaul]

I think those are little inductors IIRC - not currently near any boards to check at the moment.

[@opelstu]

Hi Andrew, I have a ps4. I can play it for ours no issues. Next day I want to play say f1 game it will randomly loose av leaving a solid white light. controller buttons wont do anything. I have to pull the mains cord to get it working again. it checks the hd then restarts with the warning of not cycling down properly then is fine for the rest of the evening. any ideas Stu.

[@AndrewPaul]

Probably early start of APU troubles - seen a few like this. Reball should sort. Cheers :-)

[@opelstu]

+Andrew Paul Thanks for the quick response Andrew. Is it expensive? cheers Stu.

[@AndrewPaul]

Nah not really mate. Expect to pay between £60-80 in the UK - just make sure they definitely reball and don't reflow it. Cheers.

[@opelstu]

Any recommendations? your self preferably ps i bought it knowing it was opened. they said to remove a build up of dust. cheers stu.

[@arkman963]

great videos indeed very helpful..thx i wonder u can help here with with a issue..im in repair service...yesterday after another hdmi replacement of the hdmi ic..my console is not powering at all no beep too..everything seems prety clean..i removed the ic completely still no power..pls advice thanks

[@Straedom]

Hopefully I wont have to replace the IC chip, but if I do, Thanks for this video!

[@Straedom]

Sadly, the person who had the ps4 before me had attempted the repair and caused some pad damage and I wasnt able to preform the repair. :(

[@sebastianbaca1382]

Is this procedure similar if I want to change the same chip from my ps3?

[@AndrewPaul]

On the MN864709 like those in the SS? Then yes, absolutely.
