Re: vertical line picture
Problem is caused by the loss of horizontal deflection signal. It is quite surprising that the entire unit is still working, since usually, a loss of H-Out will disable the entire set. Problem can be as simple as loose solder connection to a more complicated defective horizontal circuit. I would suggest havint it checked by a professional TV tech.

yap! That sound vertical problem! just solder all old parts in vertical section and check yoke if have mold? Check all looking old's electrolytic capacitors and change that if nothing happened tha'ts the time to change vertical IC.
If it's a horizontal line across the face of the picture tube, your TV has a problem with its vertical output. Most likely, it's bad solder connections to the vertical output IC. Because this part gets very hot during normal operation, the connections to the circuit board can crack and the part quits working. All you see then is that narrow line across the tube. A few minutes with a soldering iron to repair the connections is usually all that's needed to fix the TV. It's also possible the part has truly failed, but the bad connections a much more common. A service shop could do the repair if you don't know anyone with the soldering skills.
just to be sure, is it vertical or horizontal? Anyway, if it is vertical, it could point out to the vertical Ic section or some loose contacts along the lines. If it is horizontal, it could be a filter capacitor along the horizontal Circuitry. Mark the high voltage capacitors along the high voltage sections.
If the line goes across the screen you have a loose solder joint on the vertical output IC.
I've seen this happen many times in Zeniths and a lot of other sets. If the IC is not loose then there is a loose solder joint somewhere else in the vertical circuit. These IC's are 10 - 13 pin chips that operate the vertical deflection on your set. I feel like a drop of solder in the right place will fix it!
