I have had a chance to dig into this LCD projector that has been producing
ghost images.

I tried disconnecting all but one lcd panel inside the projector and it
produced an image which had a ghost image in the center but not near the
edges.

My queststion is this typical of warped polarization filters? I would
think that it would require more than one lcd to produce an image that is
ghosted like this for warped filters to be the problem.. for example one
panel would be sending light a bit out of convergence.

Does anyone have any expirence with this?

Thanks,
Mike


Well I think I may have partially answered my own question... I'm pretty
sure the problem lies in the electronics.

I set up a full screen image of dark blue and light blue text. No problems.
Convergence is perfect.

Tried full screen red... To the right there are 4 or 5 black lines 1 pixel
wide each near the right edge of the screen.

Tried full screen green. There are 4 or 5 1 pixel wide black lines to the
left of the screen.

So I guess that means the problems are electronic.. Where to start.

This is an Epson ELP-5000 projector.
