Hi!
A friend of mine gave me a dead PS5 to look at. I am totally inexperienced, but when a damage is simple (i.e. failed DAP41 on PS4s, etc.), when replacing just the IC and the other very common failing parts of these consoles, problem is fixed. So I checked the voltage of the PSU - none was present. Model is ADP 400DR. I have a bunch of spare parts around, so first thing I did was to replace the IC DAP 053 (they seem quite expensive, so I put a replacement unit - TEA2016AAT. When plugged to the power outlet, 12V did come present.
So I reassembled the PS5 and pressed the power button... to see that it was still dead. I reopened the PSU again and found out that the 12V output was gone again and the ic TEA2016AAT​ was fried (it was getting hot). After watching some youtube clips for potential solution, I tried changing couple of FET's (Q31, Q34) and so on.. but what bothers me is that the cap labelled C31 always has BOTH pads shorted to ground... I took out so many parts out trying to find the reason for that short, but just can't find it. The diodes read fine, resistors look good (I have a list to look at), no other caps are shorted... If somebody has had similar experience, I will be very happy if you help me with some clues. I attach a pic with red circle of the common ground, that cap pads, the ground of the is DAP053 and also a Gate of mosfet 10N60M2 that goes to ground...
Thanks!!
