Sharp Aquos LC-90LE757K 90 -inch LCD - lines
This TV has faint thin black line horizontally across the screen, which can be moved and sometimes got rid of by gently squeezing the back and front bezel at the left of the TV.I think it may be just dirty contacts on the flat ribbon connections, but would like a second, or third opinion before calling in an engineer, as taking it down for working on would be difficult.
TIA
