It seems kind of weird though that only one of the color guns would of failed catasctrophically but not the other ones, especially if it was a mechanical failure.
I was attempting to do a black and white setup on the tv and all I would get was a bluish green tinted picture with a slight bit of red in it, I couldn't really get the color to really go completely away.
Another weird thing is that the Color and Tint controls and the brightness and contrast controls don't seem to do anything with the TV and also the color adjustment and AGC Height and Vertical Linearity pots are acting like they might have tin whiskers because they do some weird things to the screen when I adjust them.
I have another Sylvania Color TV that is from 1974 that the tuner has failed on it, but it uses the same size of tube, and the picture tube was basically brand new on it because it was never used by the previous owner of it, I wonder if I could try to do a picture tube swap and see if it makes a difference with the TV?
