For shift look at the 9-57 board for a 330 ohm.
Change it to a 1 watt film if it hasnt been.
Upright chassii with the 9-90 board have the same issue.
Recheck that you changed ALL the 22-5001 caps. I am
sure these had 5.
Check for a 1.5 ohm at the HOT base, they drift.
Be sure the hoz hold is centered. Pix should snap right in
on channel change & not show lines. If its at the end pull
back on the sleeve & move it past the stop.
I dont remember either size or centering on these.
And last it could be what you are feeding it.

I re-checked thoroughly, no more white caps. I noticed a couple more orange drops but they're smaller than the 22-5001 caps and I couldn't read what was on them.

That's very nice too. I don't know about yours but my Zenith's cabinet is mostly plastic. You're not missing much, not having Space Command 500 like my set. No mute or remote UHF tuning, not to mentioned combined power and volume which is kind of a pain.

Here's a photo of yours from my brochure. It's a Canadian brochure, hence the odd advertised screen size.

I see only one film cap on that board; is that the one I'm looking for? (see pic). Also, is there any way to add a direct video input to this thing? The picture I get through that cheap Radio Shack RF modulator is rather disappointing.

I think its the blue one but heat changed the colors fro org-org-brown
( 330) to r-r-org ( 22K).
I remember where it was on a 9-90 but not a 9-57.

You can put video in just after the detector. It usually works
good but sometimes not. Audio I would have to see the schematic.
Try using a VCR as a modulator first.
