Zenith was famous for shorted yokes in their hybrid sets, but I remember usually it was only the vertical windings. That looks like something is WAY loading the whole power supply down. There are sometimes some ceramic disk caps inside the yoke cover, which rarely but sometimes do short. If the yoke is shorted, it can wreck the flyback. Did that problem start right away when you got the set home? I last powered it up about a year ago, and it had a full picture. Just focus problems, and this, that & the other... I wonder if something got jarred, such as a screw falling onto the chassis and lodging between a couple of those strip terminals? That's happened to me many times on those Zeniths.
