Lens Shift Issue?
I was hoping someone could help me out, I have an issue that's driving me insane. I have a JVC DLA-X570R that I got from BestBuy (I have some suspicions it was a refurb) and I've been using it pretty heavily for 2 years (it has about 2500 hours in eco mode).
I've had about 4 screens in that time, and I've fiddled around each time with lens shift to get the perfect image. However, I can't seem to get the image to line up with screen anymore (it's crazy off now, or results in bad keystoning), so I'm wondering if the lens shift is failing? From looking at the lens of the projector, I can move the image to the top-right, center, or bottom-right, but not the left. Lens shift still seems to work in all directions when I try to use it but I cannot get the image to line up anymore.
So, my newb question is, are there multiple motors at work in lens shift, where perhaps one has died and is now making my life hell. Or is the issue with my fiddling around with the projector and screen?
