Ps5 power issue - beeps on every press but is not turning on - no voltage drop on the 12 v rails no short .- fuses are ok - no signs of drop damage

hey guys,

this ps5 was working normal then suddenly started to behave like in the title. power supply was replaced and the ps5 started a few times and was deemed fixed. unplugged from power cord. a few weeks later wanted to start again but same issue returned. beeps on every press but not runing on. no voltage drop on 12 v rail when pressing power button. no shorts detected either. givin 12v/5a on 12 v rails draws 2v/5amps. fuses are ok. no signs of drop damage. any ideas?

best regards

I have had 4 machines in the last month with the same exact problem. Went through the whole mother board to see any physical issues (Caps or Fuses) and they all check out perfectly fine.
Put the power supply in a working PS5 and it boots up right away and stays on.

All 4 were being used or were on stand by mode when the power went out.
