Hello.
I have one vertical dotted 1px thin vertical line on my LG 55SM86 tv. I opened and checked every ribbon cable and it did not fix it. What is reason usually for this kind of thin line? Could it really be cable fault or 100% its within led panel itself as its not “band” that is faulty but just single line? Is it safe to swap left side cable ribbon with right just to check if its cable fault? Asking as on cable there is warnings written LEFT! and RIGHT! side, or its just for factory workers and repair shop to faster know which one goes where..
No warranty.
Any suggestions will be appreciated.
