You've checked that the cable from laptop to projector is solidly connected eh? If its loose the colors can be off.

I do projector appointments for my clients. Fired up my system today (same as I do about 20 times a week) and the projected image is yellow. It appears that a yellow filter has been put over the lens. It's really ghastly. Everything on the laptop looks just fine. It's a Notevision projector, been using it for two years without a hitch. I've reset everything to factory settings, nothing clears the problem. Can anyone give me any idea what's going on here? Thank you, Lea babies. they're what i do. www.leamurphy.com
