The line comes and goes and sometimes a 2nd line is there at the bottom of the screen. It is connected to cable and we had the cable guy in and he said it is not due to their equipment. Also sometimes if you turn the main power button off when you try to turn the TV on again you get a blue screen. You then have to play with the power button turning it on and off until it finally comes in with wavy lines...after a while a clearer picture comes in and then the black line comes back. The black line sometimes disappears and then reappears. Seems like light colored backgrounds make it appear more often as do cartoons.
