Sounds like dirty lenses to me. Do some research on optics cleaning for RPTVs. AVS is a good place to start. Also try this:

If you have a good picture except for a missing color all the various circuits are working OK. Most likely you have a bad solder joint or component in the red circuit. This would also be indicated by the fact that ocassionaly the red pops in. If you have the experience remove the boards and inspect for cracked or cold solder joints. Resolder anything that looks suspicious. If this does not fix it you will have to troubleshoot the red drive circuits from the CRT back to the video IC. Another possibility is that you have a bad/intermitant red crt. I doubt that you have the equipment to check this but you can test it by moving the green crt board to the red crt. If it now works the red crt is OK. If all this fails you will need to find a reputable repair shop to look at it. If the unit is more than 5 years old it may not be worth fixing. Good luck.

If the colors are red,blue,and green, then look for you convergence controls in the menu or off remote. If problem is more intense, then the convergence amps maybe needing soldering or replacing.
