My new TV has some issues.
I assume the complete warble on the horizontal axis is due to a component failure and not something I'll be able to adjust away.
Anyone with more #CRT experience care to chime in?
@ajroach42 It's lost horizontal sync. Best case, you can adjust the HSYNC pot to correct it. On a set of that era, it's likely sticking out the back of the case.
It could also be a signal or tuner issue. Looks like there's a fine tuning adjustment on the outer ring of the dial, I'd see if that helps.
If none of that works, it likely needs all the electrolytic capacitors replaced. The Achilles Heel of all electronics, but especially vintage.
@ajroach42 Also, if you can pick up a copy of Television Symptom Diagnosis by Richard W. Tinnell, it's a good entry-level guide into how this stuff works, if that's an avenue you want to pursue.
Looks like a couple copies on eBay in the $5-$10 range. Nothing on archive.org, unfortunately.
