I'm new to this forum and hoping someone can provide some guidance on a problem I'm experiencing with a LG 60PS60 plasma panel. Every other pixel row from top to bottom is black. Can't tell whether it's all even numbered lines or odd numbered, but one or the other is not working. Sometimes, when the set is first turned on all rows are working, but soon half of them disappear. Also on turn on, there is a period of a few seconds when all pixel rows have a dim brightness. LG techs say the panel is at fault. I'm wondering if some other assembly or connection in the set could cause this problem.
