[@Watch__This_]

Nice work, excellent explanantion and calm repair....well done!

[@ToltecMerc]

Thank you very much! I try to be clear.

[@clementkongcheukyeh1352]

Really enjoy all your repair video, you really have the patient and knowledge. May i ask if the PS4 Slim RT5080 PMIC also have the same data output as the TC7739?

[@MicroMageRepair]

Nice work as always sir, I picked up one of those board heaters as well for Series X boards, may have to try it for the next PS4 Slim south bridge too!

[@ToltecMerc]

Thank you very much sir! The pre-heater does make life easier. Barely fits on my bench though.

[@jackzedan2261]

nice video man, really appreciate the knowledge, I have a ps4 slim that have a similar issue, I checked the mosfets and they had a short, I changed them but there was still a short at the coil right next to it, what do you think might be causing it because I tried and with no luck unfortunately

[@nicolaslacoste9367]

Thanks a lot for your very interesting videos. Best regards, Nicolas Lacoste

[@ToltecMerc]

Glad you like them!

[@riparaggi]

great work! I'm struggling with similar issues with 2 PS4 slim in these days. I'll give a try also to clock replace ;-)

[@Jodasmp3]

I TAKE OFF MY HAT FOR THIS GREAT JOB, I HAVE A SIMILAR CASE THAT FIRST I HAD A FLASHING BLUE LIGHT AND AFTER DISASSEMBLY AND JUST CLEANING THE PLATE IT DID NOT TURN ON ANYMORE IT JUST BEEPED THE EJECT BUTTON, I CLEANED AGAIN AND THERE IF IT WAS DEAD I DID NOT DO ANYTHING . I NOTED THAT THE VOLTAGE REGULATOR HAD A DOUBTABLE LINE ACCORDING TO THE REFERENCE MEASUREMENTS THAT MATCHED THE ONE IN THE VIDEO, FOLLOWING THE SAME LINES, I INSULATED THE COMPONENTS AND THEY CONTINUED THE SAME AND I DECIDED TO CHANGE THE REGULATOR AND THE RESULT WAS THE SAME. WATCHING THE VIDEO I'M GOING TO GO THROUGH THE GLASS BEFORE MOVING THE SEI WHAT DO YOU THINK?

[@kaylaistired.]

i have the same model and recently my building got hit by lightning 😶 fried everything plugged into the north wall, including my ps4. im gonna open it up in the next few days to see what exactly happened, im hoping its just the power supply. there’s no beeping for the power button or eject button…

[@sj55]

Good repair and clear information again keep up the good work

[@ToltecMerc]

Thanks!

[@natek5051]

there's a bug Sony never fixed with the hdd / recovery flag... if you boot it with no hard drive inserted, then later try to boot it again with hard drive in, sometimes the flag will not be cleared... all you have to do is manually enter recovery and hit Restart System, although reinstalling Firmware also accomplishes the same thing (just more time and hassle)

[@ToltecMerc]

Thank you! That's good to know!

[@legoboy-ox2kx]

I have a PS4 slim with a weird issue. The system will sometimes power on just fine, but only with nothing connected. If I try to plug in a device it shuts off pretty much immediately and won't turn back on for a while. I ordered a new power supply, so hopefully that fixes it.

[@nikeshgupta8362]

How ever if u remove the battery the ps4 do turn on when u apply power . So cmos battery is not needed for boot up.

[@ToltecMerc]

Correct. The battery is only needed to maintain the date and time information.

Hi! I'm having the exact same simptoms, measuring 0.335V on the left side where it should be 0.275 and the same on the bottom side of TC7739. These are not going to the SB so I'm not sure if that it the correct part to replace. If you look at the board with the hdmi port on top, you see two cap-coil-mosfet pack at the top left corner of the APU. On the bottom pack I measure only 30ohms, and it goes directly under the APU. (I measure 30ohms and 0.05V on almost every component directly under the APU) Could this be a dead APU and not a SB? Thank you!

[@thall6594]

Awesome work! I have a ps4 pro that I replaced the southbridge on and that fixed the no power issue, but now it will not keep the time and date set. I have replaced the cmos battery already but the time is still wrong every time I turn it on, whether it be from rest mode or fully powered off. Could the crystal be causing that? It is very possible that I have flux left under it even though I tried to clean it all up.

[@ToltecMerc]

I would think if the problem was the 32khz oscillator it would not have started up normally. You might make sure your battery voltage is making it to the South Bridge. There is a diode under the South Bridge that is connected to the battery. Also, if it is running recent firmware, you may have to let it set the time online before it will hold.

[@Sonic2903]

How many capacitor did i loose using my hot air gun? Even when air flow is very low! You're lucky you still found them back, I didn't find any back in my case lol. Great repair!

[@optimizelogicrepair2784]

hey have you ever seen the RT5080 on these board? I believe it is the standby IC. If so, do you happen to have the datasheet? I think I have a board that this chip is shorted on pins 2 & 3. Also, do you know where I could get them? I am also wondering if there are compatible chips from other manufactures

[@ToltecMerc]

I just checked and I don't see anything on an RT5080 in my notes. They are available on AliExpress. What board is this on?

[@AfricanDance_]

hey guys! I got ps4 slim no power ,no beep , no standby volts, where should I start to repair this board??

[@ToltecMerc]

Start at the power supply. Do you have 4.8V standby? Is it there when connected to the main pcb?

no, it is not there@@ToltecMerc

21:48 Hi sir, i am getting the exact blue light ON time without 12v connected. With 12v connected same thing happens but the blue light stays ON a bit longer (but only a fraction of a second longer not that noticeable). There is no voltage going to the processor. I checked the coils and capacitors for the processor. 12v reaches there but the mosfets are not turned. I checked the power ic near southbridge. Mine has RT5080 but it's the same. I get all voltages during standby as well as during power on time as shown at 06:00. Exactly below the APU, there are some caps grouped vertically and horizontally. On one group i get 25ohms wrt ground and the other shows 1 ohm. According to my understanding, some processors do show 1ohm to 2 ohm range. I'm not sure about this. Without schematics or a good working board its really hard to know.

[@ToltecMerc]

1 to 2 ohms sounds low for a PS4 unless it is a PRO. What model is this?

[@user-hj2zt9ri6t]

@@ToltecMerc slim ps4 sae-004 board. The resistance of my leads shows 0.2ohm (dont have relative mode on my multimeter). I check 5 coils around the processor. On the 3 coils towards usb port side i am getting 1.4 ohm. Towards the hdmi port, on one coil i am getting 22.5 ohms and on the other 195 ohms. On powering on, during the brief ON period, none of these coils show any voltages. Nor does the usb ports.

[@ToltecMerc]

I just checked a working SAF-004 and it checked as 1.5 ohm on two coils and 2.0 ohm on the other. Your APU may be just fine.

[@user-hj2zt9ri6t]

@@ToltecMerc Thankyou for the for the effort. On powering on, there is no voltage to cpu. What drives the mosfets? Does the southbridge give the enable signal to these mosfets? so maybe the southbridge Is faulty? I did not get any short on any of the smd caps near or under the southbridge. This board has the 42gg one and that is almost 3 times the cost of other southbridge in aliexpress 😭.

[@ToltecMerc]

@@user-hj2zt9ri6t If your console is attempting to turn on, I think your SB is probably ok. I would look at other supplies. Is the +5V coming up. It is separate from the standby 4.8V. There are several fuses on the board. One of those could have opened.

[@DigitLineEletronica]

How many degrees Celsius should you use to solder the BGA without damaging it?

[@ToltecMerc]

I mention in the video that I use 320C air from above to install the new South Bridge. This is only possible, however, with a board pre-heater.

[@Operator_27]

Good day sir, what is the name of the board that you removed sir from the ps4 

[@miboxsamsung]

i changed cdx90042gg it still bepps eject 3times and no power

[@xreel1591]

hi i have a ps4 where one of the 5v lines goes to 0v when connected to the ps4 so i get 0v on this chip or anywhere else can the southbridge do this? or its another flaw somewhere else

[@ToltecMerc]

One of the 5V lines from the power supply(4-pin connector) is the standby power (4.8V) and the other is a power good signal from the power supply. If the standby 5V is going away, you may have a short directly on that rail somewhere on the board. I don't believe that South Bridge gets 5V directly. It only receives supplies derived from 5V such as 3.3 and 1.15 so I don't believe the South Bridge is your issue.

[@xreel1591]

@@ToltecMerc yeah actually i decided to try powering on the ps4 with a pc atx power supply and suprise it actually boots but shut off a few secs after but it might be due to the fact theres a missing resistor where the ram chip are and another component or filter cap on that other 5v line that i am not sure what it is. or there could actually be an actual bad ram chip since the previous owner legit replaced the thermal pads with thermal paste. but idk why the psu would loose voltage to 0v i tought maybe something is broken in the psu and it can't handle the smallest of load or theres still something bad that pulls too much amps

[@xreel1591]

@@ToltecMerc well lol after i cleaned the bluray drive that took me a couple of hours the ps4 no longer work even though the standby voltage is all there only thing i did different is connect the wifi antenna but i don't think that could have blow up something now i'm kinda back to square one i hope it's something obvious like a short inside one of the connector and not the southbridge that decided to die off now out of no where. yeah i had fixed the ps4 it was one of the pin on the psu power supply that was broken inside like behind the connector so it was not so visible and when testing voltage with a probe directly on the psu it would work fine i guess the power supply cable did not put enough pressure for it to make connection and its why it did not work but yeah i got that fixed at least.

Hi,where can i get the blue and white tool that you use to move the chip in the reflow? Thanks

[@ToltecMerc]

Honestly, that tool is something I made. It was a dental pick from a local dollar store. It had a metal hook embedded in the plastic handle when I bought it. Eventually the hook broke and I heated a needle with a soldering iron and pushed it into the plastic handle.
