Vertical white lines appear on the screen. Samsung provides the following information but doesn't say what circuitry they are referring to. Samsung says: DLP TV: I Have Vertical White Lines Appearing On The Screen When I Watch Video, TV, Cable And DVD.

1991 CS3515R has vertical instability. (picture often flips vertically. Seems worse when there is more light color on the screen. I remember old sets that had horrizontal and vertical stability controls. This does not. Anything I can do that would be cost effective? Otherwise it gets a beautiful picture.


By stability control do you mean the V-hold knob inside the tv? If not then the only way to fix this is to find the source of the fault in the deflection circuits. Be wary that this is a high voltage circuit and should not be handled unless you have ... Mitsubishi CS-35503 TV

My LG led has had several problems, it started out with the left half of the screen flipping as if viewed from a mirror with the right part of the screen normal. After that, it displayed vertical colored lines (blue, yellow, black, white, etc) which went away and now it shows a vertical bar about 4 inches across that looks darker than the rest of the picture.

About 8 months ago, every time I turned on the TV (SK-26H590D), only vertical lines would appears... almost like watercolor: green, orange, etc. However, you could hear the channels and change them as well... but still no picture at first. The the channel would come on after about 5-10 minutes. This has gone on since then. Almost as if the TV needs to "warm up." Today, only the vertical lines appeared but the tv never came on all day... just the voice. And the channels can be changed, but no pic

Our Vizeo P42 purchased in July 2005 has had a red vertical bar on the left side for about two months. About a week ago it developed vertical lines across the left half of the screen with no picture behind them that we can see. The right side of the screen is normal and sound is normal. Is it worth taking in to be fixed? AL


Sadly no.either your panel has been hit and damaged or the panel itself is failing.without some sort of warranty coverage, your repair cost would exceed the price of replacement. ... Vizio P42HD Television

I have a LG 42lh30 that gets a distinct vertical bar, about six inches from the left hand edge of the screen. Occasionally the area between the vertical bar and the edge will be filled with small horizontal bars that flash. Sometimes after an hour or so, the bar and discoloration on that side goes away and sometimes it doesn't... sometimes turning the tv and jiggling the wires on the Aux. AV port will make the line go away, sometimes it doesn't. Is it fixable?
