I feel I ought to chip in for another tub of popcorn TV MAN, With all the other fix-it jobs and distractions around here, I managed the following, about half an hour ago ~5 pm Sunday evening:
1) Carefully lifted the receiver on to the bench and turned it over*. Caught the brass trim piece that fell from one of the control knobs, and placed this safely.
2) Unscrewed the lower cover to expose the under chassis wiring.
3) Tinkered with the on-off switch, noting that it does not seem all that certain of it's resistance in the on position. De-Oxit has been applied.
Oh well, I may get time in the week.
*If weight is anything to go by, these are very well-built units.
I don't hold with furniture that talks.
