1-2 pixel width vertical line on my TV

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

SOURCE: vertical red line through screen

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.

By thin line I assume its one pixel in width. A single pixel wide line is an indicator of a defective panel.

42" Panasonic Plasma - Vertical red stripe 6" from left side


We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?

Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)


I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.
