Right third image filled vertical lines when hot

About 1/3 of the LCD, right side is filled with vertical lines after 15 to 30 minutes.
It looks like the pixels are longer and longer, starting from the top off the screen, until the color from the first top line is expanding to the bottom, making just colored lines on 1/3 of the screen.

Let it cool down and its working again for 15 minutes

There are 3 main circuit board in that lcd tv :
- tuner / analog board
- Backlight drivers
- digital driver for lcd itself

None of those board are sensitive to cooling with a freezing spray.
I do suppose the lcd itself have a defect, shortly after warranty of course which is very bad news.
And it looks that i'm not the only one

Did someone had this problem solved ?

How to Troubleshoot Vertical Lines on an LCD TV Screen

<p>There are two prevalent formats for video programming: full screen and wide screen. LCD TVs are designed to show a wide screen picture to go with high-definition (HD) programming. When standard-definition (SD) programming is watched on an LCD HDTV in its default settings mode, there will be two vertical lines on the right and left sides of the picture. You need to go into your TV settings menu to troubleshoot this issue.<br /> jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); <span><br /></span> <span>Instructions</span> <ol> <li> 1 Press the "Menu" button on your remote control and open the "Picture Settings" sub-menu.<br /> </li> <li> 2 Select "View" from the list of options.<br /> </li> <li> 3 Choose a viewing mode that will eliminate the vertical lines. Select "Zoom" to crop the on-screen image to fit the screen. Select "Wide/Widescreen" to stretch the on-screen image to fit the screen, or select "Panoramic/Panorama" to stretch the sides of the onscreen image to fit the screen (recommended).<br /> </li></ol>

Vertical black bar on my LG 47" LCD shifting the image to the right

Two possibilities are there. The first one is, with loose LVDS cable, that connects the T'Con board to display panel. The second is the fault with its main digital processor board.

Green vertical line on the right side of screen

Warranty still alive?
Hope so; the problem could be an expensive one.

The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.

I would be talking to Sharp - this shouldn't happen in 6-7 months of use.
