I picked up a ps5 cheap on fb market. Seller said they received it from a friend who said it would no longer power on. They didn’t have time to mess with it so they sold it cheap. I removed the power supply and tested it and it is outputting 12.33v. I’m also getting 12.33 on the fan power pin. I haven’t tested power on the motherboard as I’m new to ps5 board troubleshooting and can only find guides on how to test voltage on ps5 fats.
When I first got the console I plugged it in and was able to get power after a few presses of the power button. I get blue led for a few seconds then white, then 3 beeps and power off. However it only has this behavior intermittently and after a few attempts now I’m getting no power at all on button press.
My main question is could the power supply still be at fault even though I’m reading 12v output? My other question is the process for checking standby voltage the same on the ps5 slim vs og ps5?
It is possible that the PSU is outputting 12V and failing under load.
But I don’t think this is the issue, because the PS5 started to a white light and turn off with 3 beeps.
3 beeps I would expect at overheating. The APU is getting hot very fast and takes some time to cool down. I would check the cooling system:
is the fan spinning? (should start after pressing the start button)
are the cooling fins clean?
is the liquid metal on the APU covering the whole die?
The few times I managed to get it to power on the fan did not spin up. However after my initial testing of the console I no longer get any power or beeps when I press the power button.
The fins are clean and there is practically no dust/dirt in the console. I haven’t removed the motherboard cover yet but will check the apu tomorrow when I have more time to check it out.
Are you aware of any differences between checking voltage on ps5 fat mobos vs ps5 slim? I feel comfortable checking power rails and fuses, though I can’t find much info about doing so on specifically ps5 slim mobos.
