Those sound like what is called "scan lines" and are the result of the way the picture is "drawn" on the face of the screen. Something in the set is allowing too much drive to the screen, as these are usually suppressed during normal operation...accordianman

Thin red horizontal lines appear when viewing a dark background


Look around this sight the answer is explained here. you hace to take off the front speaker cover and a small panal undder it. you will find six knobs on a small panal. use these to adjust the settings fotr the power and they will remove the lines. You will need to have the tv on and I would sugest a normal size phillips head screwdriver not a power tool.
