Projects a pink background image. Have tried resetting to factory defaults and replacing bulb.

try a brand new cable. if that doesn't fix it then your red lcd panel is probably burnt or the lcd cable isn't plugged in all the way.

Why is my image red tinted on my LP 640 Infocus projector?

could be a bad cable which is the cheapest to try. wiggle the wire at the back of the plug while viewing the picture and see if it changes at all. if it does, the cable is bad. if not, then you probably have a bad lcd cable/connection or a burnt polarizer.

lcd panel failure or bad main board. either way, you'll have to send it in for repair.
