Epson EMP S4 Yellow/Brown Stain
We have a problem with an Epson EMP S4 projector. As you can see from the thread title the projected image has a rather worrying yellow/brown stain. It started small and got bigger, and has pretty much rendered the projector useless. When i turn it on, the Epson logo displays fine but as soon as the plain blue screen appears so does the stain. A little online research suggests that we have either a bad blue polarising plate or lcd panel. Does this sound about right, and would a photograph help with your diagnosis?
