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.
