No video on nintendo switch screen

Hello, I recently bought a non functional nintendo switch. it does not turn on. The backlight does turn on but nothing appears on screen. I looked inside the switch and found the right joycon connecter on the main board is missing from the board itself. Is this required for the screen to appear on switch?

Nope. No joycon connection required for screen display.
check the LCD connector if any mangled pin.

Thanks will check the LCK connector.
