It's possible that the switch contacts are just dirty. If you can get some contact cleaner into them you should get them to come around. I've seen similar (between the detents) behavior from dirty contacts in TV tuners... Sometimes when I'm feeling too lazy to get contact cleaner in I'll fix the problem by toggling it a bunch and letting the contacts scrub themselves clean.

I think he meant discourage not disparage...you get discouraged by a daunting task, you get disparaged by someone insulting you...

Funny. Because I used disparaged inferring that the TV mocks us and belittles us as we attempt to repair it.

Looks like DeoxIT did the job. It's been stable for a couple of days now and for long hours of use. It's just a simple toggle so I didn't think the switch contacts would be an issue considering I did work them, albeit without cleaner, multiple times. I imagined all sorts of nightmare scenarios. So far it's been behaving like it should.
