Intermittent problem with a newer Zenith TV

[Cleve]

I don't know if it's 'heresy' to ask questions about newer sets here, but I have a 1994 Zenith 35" tube tv with the AVI system for my Home Theatre that I've owned since new. About a year and a half ago, it started doing an odd thing. Sometimes, after the TV has been on for a minute or two, the picture will become very reddish purple in tint. At first, I could cure this by turning the set on and off a couple times. Then it got more persistent - requiring the channels to be changed up and down repeatedly. Something about the 'shock' of changing channels will finally cause the screen to blossom a brillant opaque fluorescent green, and then the bloom disappears and the picture returns to normal.

The funny thing is... it comes and goes since it started. The problem went away for 4 or 5 months, then resurfaced, and was persistent. Then about a month to month and a half ago, it stopped happening and the picture has been fine.

Does this sound like something worth fixing if it becomes permanent, or should I junk the TV and buy a new one? Thanx.
