Chosen Solution

I bought a ps4 slim for repair. I have been working on it for a couple of weeks. My problem is that its dead wont tutn on. Not even beep or sound. Is ent the power supply for inspection and they told me the power supply was tip top. Is alive but wont do its work. I wont give up but I still am figuring out. My guess is a damged part in the power supply.

if there is no sign of life. (no beep or blue or white light) even with a different power supply then the APU is probably damaged. and that’s almost impossible to make
