Nintendo switch lite black screen after replacing screen

switch booting up and working but with no display on lcd after replacing screen with digitizer. I dont konow if it is a motherboard issue or screen it self i allready tryed reconnecting ribbon cabel from lcd and backlight but it does not help.

I guess it is the connector. Watch out for bend pins in it. The lcd connector is the Horizontal one. Also make sure the ribbon cable coming out of the display is not damaged.
