Gamepad powers on, button presses recognized, No display

Hi all,

I just purchased a used Wii U and the gamepad powers on, the button presses and sticks seem to work fine, I also hear the noises when I swipe my fingers across the touch screen so I assume the digitizer works, but there is nothing on the display itself, it is a black screen.

I am unsure what damage was done to the gamepad if any as I purchased this used(the gamepad not working was disclosed so I wasnt duped by the person)

Would replacing the LCD fix this issue?
