I have an old teletype machine that the previous owner did the same
thing to. It finally go so bad it would not print. I mixed up some
Ed's Red gun cleaner and it cleaned out all the old gunk. Then used some
good grade of oil to lubercate it.
 
It is kerosene (which I understand part of wd 40 is) automatic
transmission fluid, acetone, and something like varsal in equal
portions. Just Google Ed's Red for the mix.

** More WD of course. The petrol based solvent does the trick.
 
The only way I know it will wind up stuck on is if the items gets hot - like the pins of vacuum tubes - and that takes years.

That typewriter was jamming or rusted and WD freed it up.

Using a siphon sprayer, I sprayed, in sequence, mineral spirits to
cut through the WD-40 gunk. Then hosed it with Simple Green to
finish de-greasing it. Followed by Distilled water to flush out the
Simple Green and finally denatured alcohol to get rid of the water.
 
I'd say it came out pretty clean.

Looks good. Will you leave it dry or lube it? If so, wet or dry?

I realize many TVs have very poor or no programming ability, some with more
utility than others. Most in Pittsburgh wonder where the local channel 13
VHF-H went. They can no longer receive the new 60 mHz ch 4 frequency with
tiny antennas LOL.

With so many on cable or other means of getting TV signals other than
off the air, I bet the TV companies spend little time worring about the
tuner part for the antennas.

Need to look at the switch routing configuration, or same on a connected
router - or other items working on your network.
 
Lots of this on youtube.
