OK, finally got the problem taken care of. No amount of deoxit,alcohol,acetone, brake cleaner, oxalic acid or just plain water would touch it. Not wanting to overdo things with the Dremel tool, I found a diamond Dremel abrasive wheel that I managed to cut into a strip the width of the plug pins. In and out of the socket holes a few times seems to have removed the deposit to the point of reliable contact.
Once powered up I found that the speaker was dead. Took a look at the connector pins on the leads that plugged into the speaker and found the same thing. Cleaned them up with abrasive and now have a working speaker. Leading to the next question...
I presently have no input source for the set .. Wifey tossed the vcr a while back and I have to order a modulator for the dvd player..
Should I not be hearing something from the speaker even with no signal input?
Static, a hiss, something? All I hear is a slight hum controlled with the volume and a short static click when I change between channels.
