Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.

    Try this, next time it happens, press the MENU or VOLUME button on the remote, this will bring up the On Screen Display. Does the line show through the display? If so, most likely a TV problem. Does the line show up behind the display? Could be a broadcast problem. Sometimes, people will complain about a thin white flashing line on the top of the screen, but this is normal because what they are seeing is the very bottom edge of the broadcast timecode. It is also mentioned in the service manual.

    Try to find a pattern. Do you see it on HD channels? Standard channels? Shows with 4:3 aspect ratio?

What is causing vertical colored lines on the left 25% of my Sharp Aquos display?


Bad TCON board or Damaged screen. You can try and replace the TCON "Timing Control Board" and see if that helps. Replacing the Screen itself is very expensive and normally about half of what the unit cost new. Here is a video to give you a clue on how to do so, it is pretty easy when you know which board to replace.

A fine green vertical line displayed on the Sony Bravia 46.


Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

Toshiba 57LX177: Right side of screen darker than left


I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.

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.

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.
