Switch Lite Back Light Issue

Hello guys. I replaced the left joystick on my switch lite and now I am having back light problems. It powers on and works fine and all the controls work as well as the sound but the back light is completely off. I’m pretty sure the ribbon cable for the back light is pushed in all the way. The ribbon cable from the sideboard to the main board is held by some tape but it was like this when I purchased it and worked fine. If anyone has any ideas please let me know.
