Wide vertical color line on the screen UN55MU6290
update 1: Extra images of the line (same part of screen w/ different screen picture)
update 2: Added video
I have one wide color line on my screen. Couple times is disapiers somehow but most of time is permanent. What I did already:
- Disconnect the LCD Flex Ribbon. Clean each of the connections with a 99% isopropyl. (non-conductive alcohal) and reinstall them - didn’t help
- I switch t-con Flex Ribbon from left side to right side - didn’t help also. So probably flex ribbons is ok.
By symptomatic - what chance that this is an issue with a t-con board? Or it is most probably an issue with flex ribbon to LCD?
I could replace board myself but most probably could do nothing flex ribbon to LCD.
