I have an image burned into my lense or lamp or somewhere on my unit.
It is casting an annoying blue ghost over overything. I want to know
if replacing the lamp will fix it or if a more expensive trip to the
shop will be required. Thanks!

Daniel

Well, no help anywhere on this. I guess I am gonna toss this in the
trash and buy a different model. Thanks anyway.

No help on what kind of device? You posted a make/model number but the
rest of the information is missing.

I'm sorry, I didn't realize that the make and model wasn't enough
enough information.

No, what's the problem with the unit? If there's image burn then the
burned LCD panel(s) need to be replaced, this is not normally cost
effective.

Like I said in my first post there is an image burned into it. A sort
of blue ghost is cast over everything. I can see a faint network logo
in the lower right corner.

Sounds like LCD panel burn if it is really there. Put up a solid light
colored image to verify that it is actually LCD panel image burn. If
it is then the panels need replaced. Might only need one or two of the
panels.

Might be best to try and find same model on ebay that has a lamp
ballast problem and hope it has good panels. Or put it up on ebay with
full disclosure as someone might want it for the lamp ballast or other
parts.

So it is basically ruined. Are there home theater projectors NOT so
easily subject to burn-in? I hate to waste another $2500.

DLP projectors are not going to have this problem.

I guess I've learned an expensive lesson. Thank you. I go in search
of a decent DLP projector.

I'm not denying that you might have burn-in, but LCD displays are
not very susceptable (sp?) to burn-in, especially when compared to CRT or
Plasma displays. As another poster said, DLP technology is not really
susceptable to burn-in, either.

Sounds like you just go unlucky.

LCDs do not have phosphors and therefore do not have the problem with
differential aging that CRTs and PDPs do. They do have a tendency for the
panels and filters to become burned, particularly the blue. DLPs that use a
3chip system could conceivably have the same problem in the filters, but the
chip itself will not burn like the LCD panel can.
