I have an Epson Powerlite 720C LCD projector. One day I foolishly placed it on top of my 12 inch subwoofer cabinet. When I fired up the projector, I noticed a dark band primarily composed of red at the top of the screen (making up about 1/10 of the total viewing area) and a diffuse band of green at the bottom of the screen. the rest of the 80% of the screen has normal color. I immediately removed it from the speaker cabinet (realizing my error) but the problem persists--a month later.

I e-mailed tech support at Epson who were of absolutely no help, they simply directed me to a service center. The service center guy totally poo-pooed that the speaker had anything to do with and asked if I had dropped or otherwise badly jarred the unit--which I haven't. His diagnosis, replacement of the "optical engine"

but he didn't really recommend it as it's $1200.00!


Has this ever happened to anyone? Is it the same case with LCD's that it is with CRT's when a magnetic field is placed too close to the screen? Is there any way to "degauss" LCD panels in a projector? I am now in officially over my head.

Just to let you know that from my experience at "projector tech inc." a company I work for, magnetic fields will not harm an LCD projector. I really could not comment on what is wrong with the unit unless it was physically looked at and underwent a series of tests. Hopefully someone could help you out with it.


Most manufacturers will diagnose and repair related projector issues but it can be a challenge to actually talk to someone who is directly related in the hands on work. Manufacturers are basically re-and-re oriented which means that projectors are usually exchanged with another refurb unit. Keep up the persistence and it usually pays off.

I'd have to poo poo it too. Can't imagine how a magnet would cause that in an LCD PJ.
