LCD Display shows vertical lines / blocks
after removing and reinstalling the LCD display, the right part of about 3" is completely black! Another vertical block is more to the middle:
To find the fault, I used Airplay to an external screen, no fault! So I guess the graphic chip is O.K! Screenshots are also O.K.
I had replaced the LVDS cable without success!
Does anybody have an idea or similar experience? Could that also be a backlight problem?
I do not know what to do!
