Hi!!

WOW! You have the exact same fault that i have!
So, i'm semi-hijacking your thread here if some have a solution for this.
I have single pixel line a cross the screen. Iv'e also noticed that wheres there's brightness in the screen the line also shines up.
(look at the first picture) If i lower the brightness and contrast in the settings the line turns black instead.

Bad LCD panels most likely. Bad driver IC or a tab bonding issue.

Yeah, if it would of been black all the time, that would also been my first guess. But the broken line reacts and changes depending of the information from the rest of the screen. Can it really do that if the panel or bond is broken?

TYPICALLY:
Main board feeds the Tcon board, it may have a LVDS cable between them, which usually plugs in on both ends. (You may try cleaning/reseating). Tcon board connects to panel, through 1st FFC(s), (one end usually plugs into Tcon, but the other end is 'bonded' to the Source/Driver boards inside the panel). And finally the Source/Driver boards connects to the TFT matrix (Screen), through 2nd FFC(s), both ends being 'bonded.'

Choose your poison. The Main & Tcon boards (usually 'USED,' pulled from a 100% working broken screen set) are usually available and usually cost/shipping friendly. LCD panels (if you can locate one) are much less available and more expensive/shipping unfriendly.
