I have a ps5 motherboard that won’t turn on it only beeps once and does not light up but this is only after a few seconds of being plugged it. I’ve replaced the southbridge SSD controller WiFi module and hdmi encoder. There are no shorts that I can find on the board. Uart error code I can’t remember but it had a description of general power failure( apu, data line short, DDR6, peripherals). I don’t think I am missing a power rail. I don’t know how to fix it at this point please help.
Mhm, maybe a Problem with one of the RAM modules.
You should re read the Error Codes and have a closer look to which specific ram is mentioned. Then try to swap it with a new one.
Best regards

Yeah so the error code is 80810001 which has the description of general power failure. I’ve bought a bench power supply to check the boot sequence and it’s been delivered today so later on I’ll reply with the amp draw.
Alright so got the power hooked up and when it started it settled to 0.061 amps and then after it went to 0.005 amps
check southbridge, 0.061amp is more like SB not turn on properly
How should I check if the southbridge is on? Do I need to check voltages if so do you have a reference for the voltages ?
