Nintendo switch lite no display but backlit turns on

[crazypete]

So I replaced the screen on my screen lite and when I assembled everything I had weird lines across the screen. Luckily I have spare working switch

This is what my screen is now but sometimes it doesn't show anything but the back lite. Can I please get some suggestions for what it might be or where to look please thank you.

DISCONNECT BATTERY then unplug lcd flex and check the connector pins, 90% twisted/mango pin inside LCD connector

The picture is from my spare switch that was working and turned on fine so I know This is 100% work. I also checked your suggestion and no bends in the ribbon cable. Thank you
