some letters on touchsreen don't work

Hello,

an vertical area on left side of my touchscreen (letters F,R,X (QUERTZ)) don't working after i've repaced it.

I testet it with 3 other screens with the same result. Maybe any SMD-part on the mainboard broken ?

Any idea to fix it?

Answer this question I have this problem too

Any signs of water damage near the touch screen connector on the board? It's the horizontal cable that is the digitizer instead of the vertical one.
