If it is intermittent, make sure it is not over heating and that it is clean on the inside.

SOURCE: projector has vertical white lines

You have dirty contacts between the dmd board and the dmd chip, or the dmd chip is bad. If the dmd is bad you'll need a new light engine.

SOURCE: Thin vertical line appears on projector

I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

SOURCE: Projector has vertical black lines going through

if they are thick and shadowy, the light tunnel is collapsing. if they are thin and defined, check the resolution. reset the settings to factory default.

Half inch crystal/ solid white vertical line on screen


Adjust the horizontal in the menu then try the overscan adjustment. If the image does not look dim you do not need a lamp.

Vertical black lines. But they are not solid. lg plasma 42pc3dv


This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.

White vertical line in the center of projected image


I have a Dell 2400MP projector that had the same problem of vertical white lines appearing over the screen.

This may seem like a simple solution, and I don't know if this will work for you, but the way I solved the problem was simply to press the bottom side of the projector, until the white lines disappear . Until now, the problem has yet to resurface.

Here's some simple steps:
1. Turn on projector
2. Connect projector to computer
3. Focus projector
4. If white vertical line appears, firmly press underside body of projector
5. See if vertical white line disappears
6. If not, try slowly pressing other parts of the body of the projector and see if white lines disappear.
7. If solution doesn't work, you may need to send it to the service center.

Hope this solution works for you.
