So I had this ps3 super slim for ages under my bed cause I forgot about it! I remembered it I intendo to fix it! It has no power, no red led, no beep, no nothing. Is there a way to bridge pins on the power button ribbon on the Mother board to se if it turns on? How do I check if the PSU is faulty? What else can it be? Currently it has no HDD but I have a 160Gb ones laying around from dead Ps3 slims. Any ideas?

Hi! Affraid that the power supply is broken, and it won’t work unless you fix the power supply or replace it with a know working power supply. I would not bridge it, I would test the easy things first before you go further.
