Funky switches in Sony KV-4000 TV

[Phil Nelson]

My Sony KV-4000 color TV has four funky little switches on the front of the bottom part:



None of these switches works, although the TV operates fine, otherwise. When I removed the bottom cover to take a look, I saw this:



These switches are tiny (at least, compared to components on the old tube TVs that I usually work on). They seem to be gravity operated, or else every one of them has a teeny spring inside that is busted. In any case, the white inner portion of the switch goes in and out when you press the tab-shaped part on the outside of the case.

If this were a larger switch on an old tube TV, I'd try to spritz a little DeOxit inside the switch in hopes of making it work.

Is that a good idea? If not, is there any chance of finding replacements?

Thanks for any advice.
