HI, I got a LG TV model 47LG70.Sudenttly all the dark part of a image display some white vertical line.

The rest of the picture are OK. In light part of the image, sometime we can see son vertical lines where the shadow is supposed to be. Any idea? I think I will open it and clean all ribbon cable with contact cleaner for now.

SOURCE: Toshiba 46In HD Rear projection TV Vertical lines on screen

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.

SOURCE: dark vertical lines on tv screen

If under warranty then of course use that.
This is a display problem. One solution someone knowledgeable in electronics can try.
This problem can be caused by a bad connection fitting of the flat cables on LCD controller board. Dis-connect the flat cables from the LCD controller(T-CON) and carefully reconnect them. Try the unit before reassembling the back cover. You may have to disconnect/reconnect several times to show improvements if this is the problem.

SOURCE: The display of the C70 has stopped working.

I recognize the problem. It mostly occurs when the plotter is exposed to moist during some days. The contactstrip which connects the computer to the screen gets moist and does not conduct in an optimal way. The result is a non readable screen with stripes

The solution is simple: press on the edges of the screen and the contact is re-established.

Red vertical lines on right side of LED TV set


It is likely the main board that processes all signal to and from the display panel (entire front screen unit).

It is also possible it is the display panel itself which is fatal.

This problems are a very tipical of the coded pixels on the LCD screen panel passes through the board that call the T-CON decoder board to causing this problems.Vertical colors lines display on the LCD screen panel happen by itself.Yes.The T-CON decodering board it is dying and shorting out.This T-CON decodering board sit in the middle at the botton of the LCD screen panel.Replacing this T-CON decodering board will solved this problems,if does not the LCD screen panel itself it is shorting out,than the tv it is not worth fixing,because changing the whole LCD screen panel itself it is not practical and the cost will be the same as a new tv itself.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.
