Nintendo switch Lite 0.41a No power

Wondering if anyone else has had this issue and its left me baffled.
I have a couple of boards which show 0.41a and dont power up. Theres no shorts on the board and the m92 has been changed before anyone says even though if there was an issue with the m92 to board wouldnt receive power either but I changed it anyways just to be sure.

Normally when this issue happens on a regular Nintendo Switch its usually down to a short on P13 just wondered if anyone knows what causes this on a nintendo switch lite or is there a way to tell if the cpu is dead without just ruling everything out and calling it a dead cpu?

Thanks
