Red color seperating

If you mean the red light is displaying offset from the blue and green then the red LCD panel inside the projector needs to be physically adjusted. If you take the projector apart you'll notice that the light source is split into red, green and blue light by passing through an optical splitter. Each color then passes through it's own LCD panel. Next, each color is joined back together by another light splitter to be projected to your screen. The red LCD panel is misaligned.

My InFocus IN2102EP projector is recently projecting a small white spot. If it was a PC, I'd say that a pixel was out. I've try blowing compressed air in various places, and have removed and replaced the...

Sounds like the DMD chip is on it's way out.
Check if the intermittent problem is related to the external air temperature. Try blowing cold air around the unit with a personal fan to see if it does the same thing.
Check if the air vents and filter is clean

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.

Yellow spots on the projected image

Hello there. First, some info you need...Green LCD=purple onscreen, Red LCD=cyan(baby blue) onscreen, and Blue LCD=yellow onscreen.
These spots (specks?) are probably dust particles that get past the filter. Annoying but harmless. To check if they are indeed dust bits, if you can focus sharply on them, then yes, its dust. To remove the particles completely will require a service. They will only return eventually. You can try to blow out the biggest offenders with some canned air. And, to help slow down dust entry, keep the dust filter cleaned so that the unit always has plenty of air movement--you'll have a cleaner image with the added benefit of LONGER life of the lamp and projector components (dust is the number 1 killer of projectors)
