Ps4pro shuts off launching games, noise from speaker, white light bar.

Hello,

ive messed up my PS4 pro. I wanted to change thermal paste, and probably damaged PSU along the way. Or worse the MB.

What happened is the disassembly was very difficult for me (I know, it’s supposed to be very easy, but it wasn’t). I had to tear the PSU with force (no, I did not forget a screw).

when I tied to put it back i bended the 2main pins, forced it in non the less. (Console didn’t work, only light bar). After that I fixed the pins, everything fits now, and it’s easy.

the console works for basic things - main menu, backup, etc.

But, as soon as you launch a game, the console shuts off, with a noise coming from speakers, white light bar stays on. From here it’s just cord disconnection to “reset” the console.

to be more exact, first couple of times the system worked for 15minutes in game, then shut off (without noise, just shut off/restart), the fan never tried to speed up during that (I tested specifically on god of war, as this one was causing “jet engine” in the past. )

Then I decided to change IC pad for normal grease. After that - as soon as I launch a game - 0 - 15 seconds system shuts off. Again, fan is at minimum speed at all times.

from what I described, is it possible to tell with confidence what got broken?

im sure it’s PSU just because I had trouble with it. 

thermal grease - I find it hard to believe that this is the problem, simply because I tried 2 different solutions - IC graphite thermal pad (it supposed to be good 35w, not cheap), and normal thermal grease later. With both of the solutions the console was quit as never before. The fan didn’t speed up to cool the system. Unless offcores whatever controls the fan got damaged…

Also, if that helps, I looked at the console with IR seek thermal camera. Psu heats at spots to 67°c/152°f, measured thru psu plastic enclosure. 

CPU/GPU - about 45°C/113°f, in an area where SOC supposed to be, but that’s not precise, I can measure only from the shield side.

I planned to take it to a shop to fix, but with ps5 around the corner, and if it’s MB and not PSU…idk, still have original ps4 as backup... 

If it was possible to tell that it’s the PSU, I would just buy one and replace myself (What are the odds I’ll screw it up again?)
