I have two thin vertical lines near the center of the screen on my 13 year old 46” Samsung LN-T4665F. Lines appear on cold start up. Squeezing the TV at the top, right above the top of the lines will sometimes change their color (yellow, red, blue, black, magenta), or make them go away. The lines go away after the TV gets warm. Does this sound like the TAB problem?
