Zenith Space Command 3 intermittant tuning

[MisterFishey]

Hey folks, new to the TV forums, but a regular poster in the audio section. Glad to be down here!

Anyway, I have a Zenith Space Command 3 TV circa 1985 that I snagged off a friend for free with an odd problem. The tuner is very intermittent. Usually when I turn on the TV, the signal is halfway there, a good picture but staticy. It stays like that for a random amount of time, then either instantly switches to a good picture and sound, or just snow. Again, this is not consistent at all. Sometimes I turn the set on and it is just snow. Sometimes it's a good picture right off the bat! I assume some capacitors must be going up somewhere (since it is intermittent), but I figured I should check down here before wrecking it. What is going on? Thanks!
