PS4 Questions PS4 Pro

Hi there. I believe I got burned by eBay again lol. I bought a ps4 pro That supposedly had no power. Went to check it and its missing the hard drive and about 50 screws. I robbed the working drive from my personal ps4 pro to test.

The blue light just slowly pulses…no video signal, wont connect to a controller, and the fan slowly ramps up to super fast in about 20 seconds. I’ve tried getting it to boot into safe mode and I cant even get that far. Ive Also swapped power supply with known good and no difference. Anyone have any suggestions? I suspect bad motherboard but I am unsure how to confirm.

Thanks!

Well looks there. Dang it. I’m gonna clean this mess but if bet i have a 5% chance the apu is still good.

Fyi…if you fill a spray paint cap full of alcohol, set the mobo with the processor facing down into it…and leave it sit a few hours 95% of the crap will just fall off. Going to reassemble tonight with the correct amount of Arctic silver and pray

I know this forum sucks, when I post I get around 300 views and not one single reply until I figure out the problem.
