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.

Just bought a acer h7531d dlp projector. From the first run, it shows vertical white lines even without a video source and these lines seem to drop a shadow on the video. Is this a serious issue? Didnt...


I have found that it has something to do with the ribbon between the controls and the motherboard. I had white lines which I can make come and go by adjusting the ribbon. I still have fine black line.

I just unhooked the motherboard and reseated it. Now the projector is working 100% correctly. I have not closed the case yet. It'll probably glitch on me when I do. So in my estimation it isn't that any one part is bad but rather that there are faulty connections. Getting all cable seated properly should be the fix.

It is all together and working perfectly.

7 wide black vertical interference bars on all screens. Equally spaced with normal looking segments. Like the stripes on a flag. On both maintenance screens and program screens, too. The bars are "fizzzy"...


if these lines are pulsating, it sounds like the connection at back of the engine where it connects to the main board. you can try to reseat it and see if that fixes it. otherwise it could be one or the other. really hard to tell without a test fixture. if the bars are fuzzy like they look like they may be underwater then that would be a bad light tunnel.

White vertical lines in image w/ 2 inch black bar horizontal.


the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
