it's unual for all 3 crt's to go bad at same time, so have you tried turning up screen(G2) control? If so also there is a cap in the high voltage line that when replaced may lighten up set. Don't have model so I can't go further.

open up the set and on the board there are 2 small potentiometers mounted on the board called Vert-Linerity and Vert Height, I believe the adjustment of the Linerity control will fix your issue

Testimonial: "Thank you so much for your help with this problem. Zenith doesn't even have access to the owner's manual on this TV anymore so your help was great!"
SOURCE: Zenith TV has me seeing red.
The red gun in the picture tube itself is shorted on. You will have to replace the picture tube itself to fix the problem. Probably want to just buy a new set. Sorry!
