Hi. Trying to learn how to find faults on boards. I have a PS5 that was struck by lightning that didn’t power on. Power supply unit was bad so I replaced it with another. Now after reassembly, it powers on for about 10-12 seconds then powers off. I get 12v on the board where the psu goes and I checked stand by voltages via FixMyApp video, and tried UART which gave me a “power or short” error. (80802220) Since it powers on for 10-12 seconds. I don’t know where to look. A different psu? Checking all the fuses? I don’t have a DCPS or a thermal camera to test anything that way. Any help or insight is appreciated. Thank you!
