It was probably a griplet connection.Those have doublesided boards with "griplets" feeeding from one side to the other filled with solder.The often developed poor/intermiitent connection inside these griplets and would cause problems.I soldered many of those back when regular consumers had a lot of these sets.BTW the one I have by my computer had a vertical problem that suddenly cured itself and never came back for 3 years so far.I thought I was going to have to solder griplets but it stopped before I had a chance to crack open the case.She hasn't been opened yet and I don't think this set's ever been worked on.The little minimanual is still intact.Gonna have to open it soon as theVHF tuner needs cleaning especially in the UHF positio which it's on all the time.Gets very snowy and a quick turn to channel 13 or 2 and back clears it up and the speaker is crapping out.loses sound and an increase in volume or a loud commercial will wake it back up.
