EDM-033 beep, no light

alex1kgr · Nov 6, 2025

So i got a ps5 (EDM-033) and i get a been (like normal power on) and no lights at all.
I checked the board and no sorts on 12v rail. 5v and 3.3v looks ok but obviously i miss something.
When i inject 12v it stays at 0.3A for the whole time (no drop at all) and the wifi chip is getting warm (not hot just warm).
I dont have uart or thermal camera ( im thinking to invest there soon).

Any ideas?

You can use 99% isopropyl alcohol to look for components getting hot if you lack a thermal cam.
But it all comes down to guessing without an uart dongle.
The PS5 might already be telling you what the issue is.
An uart is something like $10 USD so definitely worth investing in before you start randomly replacing stuff.

(note the modification he made because the original design assumes that the device you connect to also uses 5V instead of 3.3V)

There are also 2V and 1.8V voltage rails in the PS5 which drive all the main chips.
But read up on this forum for all details.

First of all thanks a lot for the reply. Tbh i don't really know why i haven't order a uart adaptor all this time...
Finally today the adaptor is here and thats the results.

Ill start checking the fuses on this line but i someone had the same issue before and can help me i would really appreciate it.

Thanks

Edit: fuse 7001 is blown. I also get a short in F7502 area (2 big caps), and on the other side of the board again 2 big caps.
