My 42" Daewoo Plasma TV has a black 1 3/8" vertical line that appears in the center of the screen. It comes and goes. The TV is 3 years old and out of warranty. Is there anything I can do?
Thank you.
Bad connection somewhere along the bottom or top of the panel, there are boards most likely along the bottom of the screen that control vertical drawing, a connection that breaks as it is heated up sounds about right. check the connectors along the bottom. Be very careful because if you wreck em the screen is junk. The connector that will be at fault will be in direct line with the black bar.
Disconnect the set from the outlet to try to reset it, lets start with this if not provide model # and brand
good luck

near the black lines. Unplug the ribbon cable and look for black chipson the underside of it, I think they say 100 on them, you need toresolder both ends on each chip. Should fix the black line issue. Your set has either a bad driver board or more likely a bad plasma panel.
