Question about LG DU-42PX12XC 42 in. Plasma HDTV
About 6 months ago I noticed a 1 pixel wide vertical purple line running down the left side of my screen. It used to be when I grabbed each corner of the TV and slightly twisted clockwise then slowly released the line would go away and not come back until you turned the TV off then on. All I had to do was repeat and it would go away again. Now when I slightly twist two more lines of different colors show up and then my originally 1 pixel wide line turns into 2 wide and turns either red or almost black. This happened far less than a year after I bought the TV and I know it's not dead pixels because if I alter it enough or wait about an hour after turning it on, the lines go away. I would really appreciate some help on this. And preferably help at no cost considering I had to pay $1100 for this Thing.

Sorry to tell you, it is not a scratch, but a bad cable connection from the driver IC's, connecting up the plasma screen to the drive board, or the drive IC for that section of the screen is defective. It is not a repair a user can do as there are no user replaceable parts inside this set. Your going to have to call NEC or an experienced Plasma repair shop.

SOURCE: pixelated lcd tv picture
usually this issue is caused by a week signal issue, those tv's need a stronger signal than an analog tv, i would call the cable company, have them come out and hook a meter to that cable, they may sujest a house amp, usually charge 50 bucks for it

This is a problem within the screen, probably the connection from the internal ribbon connector to the display. Unfortunatly the only way to repair this is to have the screen replaced.
