The click is usually a mechanical detent on the control shaft rather than the switch so the switch contacts could be completely removed and the control would still click.

It's not uncommon for the contacts to stick in a position (on or off depending on design and position it was in when it stuck). And provided the contacts did on weld them selves on or the mechanism that actuates them got damaged it should be a easy fix with some lubricant.

A back up plan if it is worse than a contact sticking is to send it to a control rebuilder(there are one or two good ones in the radio collecting community that will do TV controls too).

Thanks for the info. Time to take a control apart.

That must be what happened.

Brilliant!!! So got home and hooked up my meter to the on/off switch. Should be a 250K switch. Reading was infinite while turning on and off. So I squirted the only spray lube I had (WD-40) all over the switch while clicking it on and off. Nothing at first, but then kept working the switch and all of a sudden bingo! 265k when off and infinite when on. Think that did it.

I am having some horizontal synch issues so testing and replacing resistors and maybe a few micas in that section before firing the set back up, should get that done before the weekend. Thanks again!!!
