    Non liliput, white screen of death, ribbon doesnt fix it, motherboard?

    Started off as a color problem, so I bought a replacement Ribbon didn't fix the problem - what could It be? Here is a picture of the motherboard, looks nothing like the liliputs, but the LCD and the touch screen look identical to the liliputs - the LCD itself is a Hitachi TX18D11VM1CAA

    but now the clip broke on the ZIF connector and I get a white screen, it doesnt say RCA, or VGA just white screen, ive played with the ribbon cables for like 3 hours... any other advice?

    Picture below of the motherboard

    None of the part numbers show up on google

    White screen means the LCD has backlight, but no power to it. Could be either the LCD or the LCD controller (what you call the motherboard) that is defective.

    The broken zif could be the problem, if the ribbon cable does not seat properly and the pins do not fully connect.

    That makes sense - is there a way to test out the LCD, or the LCD controller? Or where could I get a replacement controller? I OHM'd out the ribbon cable to the back of the ZIF connector and it appears to be getting contact - just doesnt hold in place. Thanks !
