Ps5 beep once with lights and fan then shuts off

edm 020

trying to make the best out of a situation i got scammed in, i revived the ps5 non working, beeps, lights up and about 1 second later turns off. tried using my non exp brain to look around on the bored but couldn’t find anything worth mentioning other then i’m pretty sure the psu is fine, shows 12v on a multi meter

first time trying repair to please be nice
