Symptoms: No picture, and a mild squeal from the chassis.
The neck lights up just fine.

Actions so far: I changed the caps recommended in the tech section of
www.meritind.com, as well as the LM1203N on the neckboard (I socketed it
as well). No changes whatsoever.

I'm still a novice at monitor repair, so I'm not sure where to turn
next. Anyone have any experience or advice?

That's a Telco KT-1403V monitor. I have a repair guide for that one.

I had a similar problem, mine was shorting Q102 as soon as it was turned on.
Strange because there was nothing immediately associated with this component
that would do that, and the B+ was good. Scoping IC401, there was a bad
horizontal output signal. Changing Q102 and IC401 worked for me.

Thanks for the reply--I got some great advice from Ken Layton as well.

I try the repairs when my Mouser order arrives and post the results here
for posterity.

Thanks again!

Ken's repair guide is an excellent tool, if I remember correctly, it has
symptom-solution entries and a list of the most common cap failures, among
other helpful info. Change the caps listed if you don't do a complete cap
kit, the monitor is fairly old.
