Your problem sounds like it has to do with beam landing, or purity.
In a CRT type tv such as yours this can have many causes, some of which I'll describe.
- The CRT (picture tube) is magnetized, possibly by speakers being placed too close to the tv. Turning off an item such as a vacuum cleaner in close proximity to the tv can also cause the crt to become magnetized.
- The auto demagnetizing circuit has malfunctioned and requires a tech to repair
- The CRT has developed an internal fault and would need to be diagnosed/replaced. This is not worth the cost of repair.
- The yoke and/or beam landing magnets have become loose or faulty. This is internal and would require a tech to confirm or repair.
The only fault which you may be able to fix is if the crt has become magnetized. Check for sources of magnetism close to the tv. That would be such things as speakers or anything with a permanent unshielded magnet. TV's with CRTs have a circuit which demagnetizes the crt at each cold start. Turn the tv off and leave it off for 3 hours and then start it. If the crt is too magnetized or there is a problem with that circuit this may not work. You can also try a different placement, the ideal being the front of the screen pointing either directly north or south.
