I have two RCA CTC197 sets with the complaint of no audio. The first
one seemed fine, but I resoldered the audio and tuner areas just to be
safe. It came back with the same complaint. I've had both sets
running all day for a week with no trouble (both tuner and A/V
inputs). Are there any known problems that can cause intermittent
loss of audio on these sets?

I found this on Google which sounds like my problem. Is there a fix
for this problem?

Here is what you need to try first. Unplug the tv for 1/2 and hour
then plug it
in and reprogram it completely. If the sound comes back on it is not
realy a
tv defect per Thomson. The Tv-guide plus is receiving a code from the
tv
stations when they go to commercial which is causing it to lock out
the audio,
unplugging the tv will reinitialize the audio. Yes it is a nuisance,
but
several tv stations have just started sending out codes on the same
info line as
the tv-guide plus.
