Question about Televison & Video
Check the green output section circuit at the video output card for any loose soldering. This card can be located at the neck of the picture tube itself, will directly plugged to it. You can pull it out of it for repair. Re-solder all the suspected solder terminals there.
If you are not familiar with electronics, do not attempt to repair! Whether you suffer fatal electrical shock! Instead, contact the nearest service center!

Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck Please dont forget to rate this thread.

On the inside of the TV, there will be a knob with a RED cap on it, labeled vertial position. (it actually looks like a variable inductor)
With an allen wrench (possible 1/4) give it a half turn in either direction and see what happens. On the Z25x22S model, the vertical and horizontal position adjustments should be right next to eachother, but on the model i worked on, there was no variable pot for the horizontal position.
Hope this helps!

Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.
