Strange rainbow distortion in the top left corner of screen. Optoma HD 20.

post #1 of 2
Thread Starter 
I have no idea what's causing this. I recently put in a new lamp but I took out and re-inspected the bulb and housing and everything seemed fine.
I also recently installed a new color wheel, but this was the reason I replaced it in the first place (obviously that isn't the problem)!
Can someone help me figure out how to fix this?

I just noticed that mine has this same problem. Is there any fix for this?
