I have a PS5 Slim (EDM-044) that was originally beeping three times when I plugged the power cable in.
All videos and forums I read suggested the BIOS chip was the issue.
I re-flashed a good dump file from BadCaps using the CH341A Programmer in NEOProgrammer.
Now I get no power, no beeps, no lights. Voltages seem to be good.
Any help would be greatly appreciated. Thanks!
