You may have a loose solder connection in the color circuits since your problem is not there all the time. Stargazer

If you're experience in circuit board repair you can take your set apart and tap around the board with an insulated probe such as a ball plastic ball point pen while observing the picture in a mirror. When you get near the loose connection,you will see the the color change or flash on and off. Also you might try tapping the neck of the picture tube. Don't tap too hard! If you tap the picture tube and the color changes then the problem is in the picture tube.(Hopefully not!)
The circuit board that plugs onto the neck of the picture tube can develop a loose solder joint that will cause one or more colors to go off. Tap or scrape on the board while watching the picture to see if anything happens.
If you're not experienced at this type of work it would be best for you to take it to a service technician.
