The customer said that while changing channels she lost the sound. The
set was brought in here and after being unplugged for almost a week we
powered it up, autoprogrammed it and the sound seems fine. I do not
have cable so it is set for off air channels, not that I would think
that would make any difference. Its been running for a few hours now
and I have tried changing channels a few times and it has not quit,
yet.....
I have had some of these CTC203 series sets come in here before with
odd complaints and just like this one after having been unplugged for
awhile we plug them in, do the autoprogram and have had many go back
out again after never being able to confirm the customers complaint.
Does anyone have any theories as to what may be going on with these
sets, particularly this one? All these lucky Thomson owners couldn't be
crazy, could they? Thanks for any advice. Lenny Stein, Barlen
Electronics.

I've seen at least two RCAs with a no sound complaint that I could
never find a problem with. I think it's a software problem that's
reset by unplugging the set.

Thanks for the link!

Quoting that page (and correcting a few instances of 'XDS'):

"It's been identified to a non-standard signal originating in particular
"XDS box" in the transmission chain (XDS means "extra digital services"
and includes closed captioning, auto clock, program guides, VIR color
levels, etc, all broadcast in the vertical interval).... the signal
originating in this XDS box made by the "XYZ" company (name deleted)
has 2 extra bits...It causes a buffer overload in the micro and mutes
the sound....this XDS box does not truncate the data stream and the
extra bits get broadcast."

Is this the first recorded case of a television set malfunctioning due
to a buffer overrun attack? Anybody sent this to RISKS?

I still don't know if it's first, but I sent it in to RISKS. Thanks
again for the info and link.

i know this is not an answer to your question, but i am currently
experiencing a similar problem with my 35' set. i've owned it now for 6
years without any problem. last night (1/2/06) i turned the channel and
had static noise instead of sound. i found this on 99% of the channels.
only 3 and 6 (pbs stations) had sound. and it wasn't in sync with the
picture. it was some sort of public radio. i checked all the other sets
in the house and ruled out problem with the cable. so now i'm wondering
what's wrong and if it's fixable. i'll try unplugging it for a while as
someone else suggested, but if anyone else can help, i'd be thankful.

just to let people know, unplugging my tv for a little more than 1 hour has
solved the problem. i guess it's an easy fix. thank for the help

Here's the fix!!!! Take a 1uf@50v capacitor and solder the negative
leg to the shield around U13101 and the positive leg to pin 15 of
U13101. thats it, no call back. this does fix the no-audio problem, but
it disables the closed caption feature. i got this fix from here...
