How do I get rid of this one vertical white line on my toshiba TDP-S8


take the cover off, disconnect the the connection on the rear of the lens assy from the main board, clean with an approved electronics cleaner and then reconnect. Sometimes this fixes the problem. If it doesn't, then the DMD on the rear of the lens assy is bad or the main board is bad. Hard to tell without a test fixture.

White areas in the image are yellow and the black are blue-green


you have a few issues. first is the yellow in white. the light filter on the blue lcd panel is fried due to excessive dust and heat. unfortunately, you may have to replace the whole optical engine. as for the flashing horizontal lines, the power supply isn't cooling down and the caps are drying out, causing fluctuations in voltage. so, replace the power supply.

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.
