My nintendo switch doesn't turn on or even charge!

Hi ,i recently got a nintendo switch V1 that doesn’t turn on or charge.
I opened the switch and tested all the capacitors for shorts but none of them was ! Even the fuse and the coil was good.
I noticed that the charging port was replaced by someone else ,and it wasn’t exactly like the ones on the internet that i compared !
I wonder if the port has something to do with this problem or there is a different problem ??

Ps . I didn’t tried to test it with a different battery because i don’t have another one ,only have my switch lite that i bought brand new and i don’t know if the battery works on a standard switch :thinking:.

Anyway, some help please :sweat_smile::+1:
