#75 Repair of PS4 Slim Fast Shutdown

[@shakangel666]

Amazing troubleshooting skills!!! I've never seen someone on KZbin understand and chase down a problem like this one without schematics. I really enjoyed this one. Awesome!! Keep them coming please!!!

[@ToltecMerc]

Thank you so much! I do enjoy the hunt! Sometimes you just know it has to be right in front of you!

[@maniax199]

I love your videos. Always explaining your logic to find the folt. I noticed in 27 min that one of the three resistors had a hole in it (the second one). Thx for your great videos.

[@ToltecMerc]

Thank you! I did not notice a hole. I still have the resistors so I can go back and take a look. Thanks for watching and commenting!

[@geraldnaicker32]

Excellent video, the best ps4 troubleshooting video I've seen thus far

[@ToltecMerc]

Thanks so much! I'm glad you liked it!

[@toolsarecool]

Tricky one, nicely tracked down!! Funny that it turned out to be the FB resistors after I thought I saw what looked like a pinhole (probably wasn’t) in the middle one @28:40 Very educational repair, THANK you for sharing these!

[@ToltecMerc]

I'm pretty sure that's a solder ball. I think these resistors just age over time when exposed to heat and high voltage.

[@Sonic2903]

Brilliant. Absolutely brilliant. The more videos I'm watching from you, the more I'm impressed and enjoying to watch! :)

[@ToltecMerc]

Thanks so much! I'm glad you liked it! Hopefully, more to come.

[@Magsyboy]

Geez ur so good at this sir!!! Its a trash to most of us, but you make it came alive again with a proper diagnostic… thanks for educating us it helps earth greener

[@ToltecMerc]

That's very kind of you. Thanks!

[@rdflo6739]

Fabulous Repair. Thanks for sharing. I particularly like it that you share the thought process and trials and failures. Really useful and interesting.

[@jonathansandiford4137]

Thanks m8, I been struggling with this exact problem on 5 different psu. I was speaking with SteveBe just yesterday about it, and he was of the opinion that I should check those 2 meg resistors as they deal with current sense for the power factor correction ic. Thanks for posting this. I certainly enjoyed it!

[@ToltecMerc]

Excellent! Steve Be is a wealth of information!

Great video to help me with the really similar problem I have with PS4 Slim customer brought to me

[@ToltecMerc]

Thank you! I'm glad it helped!

[@erroos]

@@ToltecMerc in the end it wasn't power supply issue, but i knew alot new with these vids

[@Andreapippero9201]

Thanks for sharing! Very ineresting and helpful! I've the same problem on my psu ADP-240CR (I've found a bug that have shorted mosfet FB13), checked the resistor with multimeter they measure 2.42MOhm that seems a little bit low because they should be 2.7MOhm, should I try to replace them? which wattage and tolerance should I buy?

[@ToltecMerc]

It is very difficult to measure high value resistance in circuit because of parallel resistances and voltage remaining on capacitors. Desolder the resistor and test again. I find it easiest to heat the resistor and just spin it around so it is only making contact on one end but is still held in place. Also, you might clean any flux off of it before measuring.

[@a.a.2677]

The middle 2MOhm original resistor had something on it, not sure if it was a solder ball or a pinhole (43:48). Aniway, very interesting repair. 🙂

[@ToltecMerc]

Yeah, solder ball I think. Thanks for stopping by!

[@John-oo9xu]

Hi mate, can you tell me what power supply bench you have? Like what specs. Thanks in advance!

[@ToltecMerc]

I have several bench supplies. In this video, I used an old HP E3620A. It's a two channel, 0-25VDC, 0-1A power supply.

[@John-oo9xu]

@@ToltecMerc Thank you!

[@tyvaye]

thank you for the video, I replaced the resistors but the problem persists, unlike you, I have to plug and unplug the power cable for it to work if I let the capacitors discharge, I have to do it again as at the beginning. Do you have any ideas please? thank you for having

[@JoseRivera-cd8xb]

hy... have a ps4 slim as that one with same simptom turns of then off like that one and stays dead until u unplugged ac power and same thing again... u recomend swap power supply? thnkxx

[@ToltecMerc]

That does sound like a power supply problem.

[@karlhartl7371]

Please Teacher... where is the 39 ohm resistor located... it is connected between which pfc pin and which 12v ic pin.. please

[@ufo540]

This defect of pfc voltage falling gradually after the power on happens quite here in Brazil .... thanks for the tips. ...

[@ToltecMerc]

Glad it helped!

[@rfr653]

Good job mate 👍

[@ToltecMerc]

Thanks! Just about to upload another!

[@theevee1995]

You're awesome, my PS4 is having the same problem, unfortunately I don't have these skills 😊😊

[@GearZonom-b6z]

I haven't seen this model ps4 that looks like this. Is this a model from overseas like uk or japan or somewhere

[@ToltecMerc]

It’s just a standard PS4 Slim. It is missing the outer shell.

[@GearZonom-b6z]

@@ToltecMerc i work on own stuff but just never seen a ps4 slim with this kind of plates is it an off brand plates cause it doesn't look normal to me but then again i never owned the slim model. But seen tear downs and stuff like that and never seen one with this kinda of setup with the antenna place ments and stuff

[@GearZonom-b6z]

@@ToltecMerc i still found the video interesting by the way it just looks funny compaired to some others i seen. So yea just werid curiosity of why it looks like this unless its a revised version i just never seen

[@LucaSpeedd]

Intermittent faults are really hard to find the cause. these feedback loop resistors usually change because of the glue that over time creates resistance and changes the value of the resistors, I already got some that just cleaning the glue solved the defect..

[@ToltecMerc]

Hmmm. I hadn't considered the glue. Thanks for watching!

[@Senux-Video]

Perfect. At first i think, issue is one of capacitor (filter) 450V/47mF.

[@ToltecMerc]

Thank you! The capacitors are a possibility.

[@josedavidjerez9076]

muy bueno el video ...bien explicado ,habra forma de que se pueda tener subtitulo asi de sa manera se entiende mejor cuando explicas

Can you send us a link for the 1101c chip, you can send pm nicely , does your veriac have a separate isolating mains in Tx, can find unit of hear i do have variac and mains isolating tx just be nice to have a all in one looking good…

Hi i was trying to fix an adp-300fr today which was roach damaged.I replaced the fuse and the 40N60M2 that was blown also the 1612A3 but i cant get the volts on the caps to go to 395V like it should when i try to turn the 12V on. I checked the line from pin 8 of the 1612A3 but there is nothing damaged there. . I dont know what else to do :( Your videos are amazing pls keep making them i really appreciate all the work you put into them. Thank you!

[@ToltecMerc]

You may have to find another supply to compare to. You can see if your high voltage is trying to go up briefly and shutting back down. There are some large value resistors in the feedback circuit that can be damaged. They will cause this issue.

[@nikeshgupta8362]

@@ToltecMerc Hi thanks for replying I checked the resistors which were in M ohms on the feedback but they seem to be ok even replaced them but no change . They goto 2 transistors Q1 and Q2 going to replace thoes n see . The voltage does go up to 325v from about 310v then it shuts it self off . I replaced thoes 2 transistors but still the same the volts won't goto 395v any suggestions on how to test the pfc circuit ?

[@nikeshgupta8362]

I managed to fix it . I re soldered all the optos and the DNP012AH chip and its working fine.

[@jameskenney5623]

I just found your channel, and I'm hooked. Thank you for all of the great explanations that you do. I have a long way to go, but I love to learn. Where would you suggest I start? I have almost all of the tools needed, and I can solder. I just need to understand how it all works together like you do, although it seems like you probably did something like this for a living. It's clear you didn't just hook up a multimeter and expect to immediately find a problem. You understand how it works better than any other KZbinr I've seen.

[@ToltecMerc]

Thanks for the kind words. I have been working with electronics for about 40 years but only recently started working on consoles. I’m having a lot of fun. I would recommend buying something broken and start trying. You can learn a lot watching others so it is a good idea to pick something somewhat common that others also work on. You really have to learn by doing. You will pick up knowledge along the way. I don’t recommend starting with power supplies because of the dangers. Good luck!!

26:58 - Whatever happened, it changed sound.

[@ToltecMerc]

I'm not sure. It sounds like my microphone came unplugged so the camera switched to the built-in microphone. Or perhaps my microphone got covered by the coat I was wearing.

[@orion310591RS]

​@@ToltecMerc I have one suggestion/idea for youtube videos. Im not quite sure how its done, but I hope you will understand. You know that on video timeline, there is a possibility to show like segments, chapters. So on mouseover, people can see where which segment of video starts. I think it would be good overview, if we had something like that in those videos, for example 00:00 - 7:00 Visual Inspection, 7:00 - 9:00 IC1 , 9:00 - 13:00 IC2 and so on... then mark "Resistor solution" at the end. I know its one more step in editing on youtube but I believe it will be worth for viewer. He comes to this video and see, oh there is segment for this IC2 i wanted to check, I wanna see how he did it. And then he watch it. Othervise, he will just skip 42min video not knowing that info is there.
