Hello everyone. For a few days on the screen of my LG 55 B6V oled TV a very thin vertical black line (just over a hair thick) has appeared that crosses the entire screen, from the upper edge to the lower one, about 5 centimeters from the left edge. I have already tried deep cleaning the panel, resetting to factory conditions and loaded the latest official software update (the one that came out last year) but without success: the thin black line is always present. This damn line is present above any image, using any source / input (antenna, hdmi, usb) and also overhangs the on-screen menus or the red pointer of the wi fi remote control. In your opinion, could the problem be solved by changing the main board of the TV or is the panel irreparably broken? Thanks everyone for your attention.
