Switch turning on only 1 second

Hello all,

i have a nintendo switch which starts just for a second and turn black. It is charging the battery.

When i unplug the battery and plug it back in it and plug the usbc cable in, it shows me the charging symbol for 1 second.

I checked a new battery, m92 and p13 were replaced already.

When i plug in the board into an ampmeter, it draws 0.250a on goes back to 0.00a after that second.

I dont know where to go on, hoping for your help.

Kind Regards
