There are two STK on conv. board, even if they are not 392-180.
To know if the STK are the problem, test the pico fuses at base for continuity. Replacing STKs require a precision soldering job, using thermal compound and taking care not to damage C board. This is not a job for beginners, and should be done by an experienced technician.
I have a GE 46 in TV that had the same occurrence. I believe it is a sign that the amplifier is overheated or stressed. The way I fixed mine was to unplug TV and leave off for a few minutes -then plug in. I discovered this by accident when the power went off one day and the sound returned (had been using my vcr audio output plugged into my stereo for weeks!) This fix will work for weeks-sometimes months-evidently resets the circuits inside the amp somehow. Last time this happened I also removed the back of TV and blew out the dust with compressed air while it was unplugged-still have sound 4 months later without a "reset"-so I'm guessing it did help .
