SOURCE: White vertical line in the center of projected image

Hi there

This is a common Mainboard problem on Projectors.

The only way to get rid of it would be to replace the Mainboard or have it repaired.

Must warn you that it could turn out to be a expensive exercise !

omg, I just figured out why OUR projector was doing this! There was an adaptor plugged into it that we use to hook it up to cable to watch games/tv shows sometimes...once I unplugged that from the projector the lines dissapeared!

SOURCE: Thin vertical line appears on projector

Hi Martin103

This is a typical BenQ Mp Series problem , and will notice that it will start of intermittently , but later on the white line will appear every single time.

This can only be fixed by replacing the Mainboard of the MP710/720/721

I plugged in the acer dlp and it came out a white vertical lines in the display,is it at the bulb? or is it in the settings?


this sounds like the DMD board on the light engine not working properly. It's not something that can be fixed in the settings, but it is a hardware failure. light engines are usually very costly to repair. if the projector is still under warranty have it serviced by Acer.

We have an ACER PB726 projector. We have replaced the bulb but there are vertical white lines showing on the screen both before a computer is connected and once the computer is connected.


try to go to BIOS then check if you can still see the vertical lines..if you can still see those lines most likely there some damaged on the screen..you may wanna call your manufacturer to check the service for your pc

Vertical line white, regular, blinking.


I don't think it's the bulb. Sounds like an LCD panel issue. Maybe one or more of the 3 LCD panels is either not working right or the unit has been dropped/jarred and the panels have moved (All three have to line up right optically to give the right colours). You need to take the projector to a qualified service centre.
I hope that solves your Problem, If so kindly accept it.
Thank You, Arjun.

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.

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.
