Hi, I'm experiencing vertical lines on projected image from a Dell Data Projector.(Dell 2400 MP) White vertical lines are appearing at even spacing across the width of the image projected. They appear even with no input attached. Any ideas as to what could be causing this problem? Thanks a lot!

Had problems with image processor on this model

this has happened to many of these tvs, I would return it if you can, this isn't worth it to get fixed. I'm sorry if you can't return it, yours lasted less than many I have heard of

light engine or bulb is gettingbad ok how many hours on bulb fans clean ect thx nick

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

clock and phase are off. go into menu and reset the settings to factory default.

that is due to lcd filter units , try to align, precision work

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.

I had a smililar problem after taking it apart i realised that i had screwed my mount skrews into the video main board and cracked it along with a few soldered wires, if you havent done any physical dammage to it try a firmware upgrade

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.
