My Switch won't turn on even after replacing battery

My Switch won’t turn on nor does it react to charging. I’ve tried using a different charger (that worked on a switch lite) and it didn’t work. I concluded the battery was at fault so I bought a replacement and replaced it(using equipment and guide from ifixit).

Still; nothing is happening. Won’t react to a charge.

I tried checking the charging port but it doesn’t look wrong when comparing with online images.

Would be a huge help if somebody here could help med out!
