Nintendo Switch Display won‘t work

Hey guys, so I did a shell swap on my Switch today. But when I put it all back together my screen wouldn‘t work properly. When I turn on my switch the backlight will turn on but there will be no nintendo logo or anything.
I only get a picture when I put it in the docking station.
Is that a common problem with a ribbon cable or could it be something more serious?

Mostly likely a bent pin in the lcd connector. I would check there first.
