Vertical lines on my Optoma HD20

[BehroozAraz]

Folks I seem to have solved the problem - at least for now. I called the Optoma service center and explained the problem and that it was an on and off recurrence. He suspected a color wheel problem. I dismounted the PJ and heard some strange noise like a loose screw going around in the PJ... I suppose it was touching the color wheel and causing the problem. I tilted the PJ around till I heard no noise and reconnected the PJ and voila! no vertical lines!
I know I need to someday open the PJ at the service center and remove this foreign object but for now the problem is gone
I also managed to calibrate the PJ with settings I picked up on projectorreviews.com and the PJ is performing brilliantly for the money!

I had the same problem last night, I tried adjusting the projector and the lines showed up. I of course freaked out. I took it down and also heard a rattling of some kind. I opened it up, took the lamp out but didn't see anything. I put the lamp back in and put it back together, have it a shake and didn't hear anymore rattle. Turned it on and the lines were gone. Hope it was just a fluke. I won't be attempting to adjust it while it's on anymore. Did you ever have anymore trouble with the lines? I read some people saying it was a DMD chip thing but I dunno.

Perhaps one can also give a shot on hd 20 also.
