Chosen Solution
I had a broken digitizer and tried to replace the screen (LCD+digitizer) So cable connected and tested -> Working Glue added, cable reconnected and slightly pressed on glue while trying to get that cable to bend the right way. When everything was in place, I tested the display again and found suddenly vertical lines extending from bright (e.g. white) elements shown over the whole height of the display. This now happened twice to me and I can’t figure out, what I may have done wrong. Any ideas? Start:
Kinda invisible:
After boot
Double check the connection and the ribbon cable to the LCD itself, it may have become damaged. My guess is the ribbon cable directly coming from the screen somehow got damaged during installation. That looks like ribbon cable damage / bad connection.
