Transparent gray vertical line on sharp tv

This line appeared and I'm not sure why. It takes up about a third of the screen on the right side. It's transparent, but annoying as heck. Please help me.

SOURCE: 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.

Visual transparent lines at top of picture


You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

Thin blue line


I am a Sharp Servicing Technician. You posted this before. Ive got the same model TV as you do LC46D62U. I think the line you are experiencing is simply the broadcast. I notice it on some HD shows that broadcast the side bars. (Always on the Ellen Degeneres Show). Ive taken some picture.

1) Here's the line on the left that i experience

2) Later on in the broadcast, it goes away.

One way to check if its a TV problem or not. When the line shows up again, hit the MENU button on the remote. If the line appears to be "behind" the menu, then it is simply the broadcast.

If the line appears to be "on top" of the menu or shows right through the menu, then it is a TV problem.

Im thinking the reason it takes hours for hte line to appear is because it only shows up on certain shows or certain HD broadcasts.
