UART Code 80060004 - 1sec BLOD - Unknown code (Solved!)

[Takezo-San]

So Initially I had a bad WIFI chip and replaced that. I used the UART codes to diagnose that issue (Using PS5 wee tools software). Installed new chip and went to test but I still got the BLOD.
Bench Power supply shows 12-14ma then hikes up to 310ma and then back down to 12-13ma where it hangs and switches (sometimes off and on in a flash) and then shuts off completely after 10 seconds or so.
Re-hooked up UART and got a new code only on error log 04. The rest of the error logs are c0020303. The code in question is this:

(OK 00000000 80060004 00001824 FFFF0005 10000100 2157 0036 3560 1995:F8)
It says not found in list, report findings.

I've checked all fuses and voltage rails seem fine. All voltages present. No shorts. Thermal cams show nothing.
I'm befuddled as to what it is now, though its could be a voltage controller chip or RAM?

Any help or anyone seen this before?
Thanks

EDIT - I used Dony tools UART software to read the codes and it said VRM related. So I was checking the standby voltages and the On voltages (by pressing the on button on the PS5 console periodically to test) across the inductors (6 of them) and they all gave me 0.9v. Then whilst checking again I got a pulsing blue and then white light!?

I hooked up the HDMi and it started working!? I'm not sure why it does but its working.
Its not perfect as after putting it back together, it fails the first boot (with white light) but pressing again it works like normal.
I can only assume my DMM gave some component or chip or rail a boost in miniscule voltage!? Any ideas if I should replace any thing or put it back together as is?

SOLVED

So I turned on the PS5 again and it gave the BLOD as it usually did. Then I went back to the VRMs and probed the Inductors with my DMM in voltage dc mode again and then powered the console on and it worked again. And this time I used a thermal cam to see if any ic got hot....Straight away one of the MOSFETs on the VRMs lit up.

It was just the one MOSFET and it was the one in the attached picture attached

Couldn't find an exact match for the SIC655A MOSFET but its a 60A power MOSFET and quick search online landed me with a place that sold a compatible NCP252160 MOSFET.

(So my guess is to why it worked when I probed the inductor near that FET was probably my DMM gave ,half dead/ internallt shorted, FET the voltage it needed to open its gate!? Thus giving a temporary surge to the line or FET, enough voltage to get the system working as normal. And it would also explain the boot sequence numbers being mostly fine but the random 12-13ma switching on and off rapidly when turning on the console)

So MOSFET is Installed it and it booted no problems now. Thanks to @stetofix for his input in other threads about related issues and this Reddit Post . Both helped me figure this out, especially Dony-tools UART software.

Thanks and hope this helps someone down the line

The exact same thing happened to me on a PS5. In my case, the console almost always turned on, but when I started a game, it usually turned off, although sometimes I would spend a while playing. Checking with a thermal camera, when starting a game, that mosfet heated up less than the others; without playing, it heated up normally.
In my case, the error 80050000 Severe Main SoC CPU Power Fail and 80060000 Severe Main SoC GFX Power Fail - SoC VRM Power Fail (GFX) - VRM Power Fail (GFX) appeared.

Awesome, glad this helped you. Did you replace the MOSFET?

Yes, of course, you can see it in the photo. It's also different from the other PS5. Everything works fine now. Thanks for sharing.

Amazing. Well done and happy gaming! Also crazy that its the exact same MOSFET too. Weird

Yes, according to the thermal examination, that mosfet and the one next to it are always working with the console on, the other 4 following ones work together with these when the PS5 requires power (launching a game)... that's what I think, that's why those 2 mosfets are the ones that should be damaged first.

I have the same problem error:
80060000 Main SoC GFX Power Fail - SoC VRM Power Fail (GFX) - VRM Power Fail (GFX): Couldn't get the error factor.
the ps5 sometimes doesn't turn on and other times it does, when it turns on it lasts for minutes or a little more, the only thing I've noticed when measuring the coils when I send them all they are at 0.90v but once it turns on they go to 0.70v, with a thermal camera I don't see anything strange, only that of the first 5 mosfets are working, the others turn on from time to time, the 12v are stable. I don't know what to measure anymore.

I had this error come too. The console would work for extended period but once I would shut off and restart, it would BLOD. Wait like 10mins and then would work. So I went into fix and checked UART and it initially gave me Infeon chip check. So I had some ordered from Aliexpress and it didn't work and gave me a new error of 80060000. Now Im stuck because I have no clue whats wrong either. Thermals are fine and VRMs get 12v but i couldn't see voltage lines on the infeon chip. Some said southbridge but I will have to check all the lines and see where they are missing. Did you get a fix for it?

Turns out I replaced the Infineon chip I installed had a bridge and was the reason a vrm mosfet died. I didn't think much of it but I had intermittent shorts on the board. So I found a definite short on the board, injected voltage and the apu lit up so....Game over for me. Seems the bridged solder pins on the Infineon chip was critical because it sent the wrong voltage to across the board. Bad mistake and after research, that chip is the most important PWM chip on the whole PS5, if not the most important chip. Silly silly mistake.

So I think that UART code is still valid because it shows there is a short connected to the VRM circuitry. In someone else case it might just be a cap so who knows. Hope this helps someone down the line.

A mí también me salió este error. La consola funcionaba durante un tiempo, pero al apagarla y reiniciarla, se bloqueaba. Esperé unos 10 minutos y volvió a funcionar. Así que entré en la reparación y revisé el UART, y al principio me dio la comprobación del chip Infeon. Pedí algunos en Aliexpress, pero no funcionaron y me dieron un nuevo error de 80060000. Ahora estoy atascado porque tampoco tengo ni idea de qué está mal. Las térmicas están bien y los VRM reciben 12 V, pero no pude ver las líneas de voltaje en el chip Infeon. Algunos dijeron que era el puente sur, pero tendré que revisar todas las líneas y ver dónde faltan. ¿Conseguiste una solución?

Resulta que el chip Infineon que instalé tenía un puente y fue la causa de que fallara un MOSFET VRM. No le di mucha importancia, pero tenía cortocircuitos intermitentes en la placa. Así que encontré un cortocircuito evidente, inyecté voltaje y la APU se iluminó, así que... ¡Se acabó! Parece que los pines de soldadura puenteados del chip Infineon eran críticos porque enviaban el voltaje incorrecto a toda la placa. Un grave error, y después de investigar, ese chip es el chip PWM más importante de toda la PS5, si no el más importante. Un error muy tonto.

Creo que el código UART sigue siendo válido porque indica que hay un cortocircuito en el circuito VRM. En otro caso, podría ser solo un condensador, así que quién sabe. Espero que esto le sirva a alguien más adelante.

Finally I replaced the xdpe and the 3rd mosfet and everything was solved, thanks
