Color Issue with Zenith tube set 16z7c50z

Look at the heads, there is a red shadow on the left then a blue then red 'ghost' like outline on the right. It seems to be worse when cold. Also does it with dvd or any source. Any Ideas where to start?

sounds like a convergence issue.should be an easy fix.can you post pics?

[ctc17]

Sorry, should work now. Its not convergence. Has a perfect bw picture. Its almost looks over driven or distorted.

If the fine tuning is set properly, this could be a color bandpass or sound trap alignment problem.

Also, I see another problem, that the color subcarrier is not being trapped out of the luminance (all the dot patterns). Did this set come from someone who might have fiddled with the adjustments in the color section?

How is the sound? Any evidence of overloading (buzz that changes with the picture), that might indicate improper AGC setting?

[ctc17]

The alignment has not been touched. Its getting worse on its own. The dot thing is fairly new too.
The sound is perfect on this set. No buzzing at all

sorry,didnt see pic.that is an alignment issue.of course check fine tuner.if this doesnt fix ,then look to coil in color circuit.i have 3 zenith tube sets and all three had the same problem.one was tuner,other two were alignment.you dont have to turn it much to get it right.be careful.i have turned and twisted for days on this.sometimes i get overzealous!
