The Guns are going out slowly. This has been a problem with this model before. There is no quick fix to the solution you can wait until the whole thing goes or have a tech look at it personally.

Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines.

Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

Vertical colored lines on top and bottom of screen


Definately a video processing problem and it may need a logic board it is called. Does the set work fine if you feed component into set to bypass all that? Let me know. GURU JAY

Color line across the center of a black screen


Hi. this is caused by dry solder joints on the frame o/p IC. Resolder all legs of frame chip. Should sort that out.

Picture problem


Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
