How often do these things go bad? Just wondering if it's common or almost never for them to be a cause of color loss. I think it is a 3.57Mhz crystal. I slow started my 64 Zenith 5111 which was a couple of decades dormant and was pleased with a great color image.
It was interesting how the TV came to life as initially there was only black and white and then in sort of a spiral the color came in starting in the center and moving through the entire picture. That lasted a a couple of hours or so and the set went black and white again. None of the adjustments make a difference.
This was a while back and someone here sent me a replacement crystal that looks like a capacitor; like a large, thick ceramic disc dipped in blue plastic. It's some kind of modern sub that is supposed to work. Anyway, I hardly ever see posts or threads on these crystals and the role they play in loss of color. My bet is that the set has a bad cap (of course), but it would be nice if the crystal was the culprit.
