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

Does anyone know the part number for DMD chip in Acer X1260 projector?


Hello i got issue with white and black dots on ACER X1260.
The orignal parts was a 1079-6319W...
I tryed to put on a 1079-6329W supposed to be compatible.
I got white vertical lines on screen and no more pixel dead, this reference seems not compatible ( i think its 18W->19W ; 28W ->29W only).

I tryed to clean up with KF special contact F2, chip pins, socket, cards connectors, but nothing worked, still vertical white lines with 1079-6329W chip ( instead of 1079-6319W).

I hope this can help everyone in trouble with Acer X1260 and other.

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.
