Default xbox one s power on beep power off

Hi all

I have an xbox one s which looks to have been water damaged and can't stay powered on. Powers on for a second with a light + beep then powers off.

I've removed as much of the water damage as possible.

I have 1.1v, 1.8v, 3.3v, 5v, 12v rails

All 3 power fet rails are good and each fet tests ok, this includes the two behind the front panel connector.

I've checked ports for damage leading to possible shorts.

All large inductors + any small ones I can find for shorts but found none.

I've tested all inductors + resistors under the sb for shorts and found none.


Anyone have any ideas where I can go from here? I am pretty much out of ideas and starting to think my issue might be sb or apu related (erring towards apu)
