Here's a article that expalins the phenominia
In response to a question by a friend of mine who runs a service shop in
Florida, I made an inquiry for further information about the newer RCA
TV's which exhibit the problem of "no sound....unplug for 15 minutes to
correct." We've known about this problem for some time, but have never
had the whole story on it - till now. The person I spoke to would only
talk of it with assurances of anonymity and no mention of the company he
works for. I felt like I should put on a trench coat and meet him on a
street corner in the dead of night.....He is very concerned that
anything said would come back to bite him and his company in a court.
As for my putting this in a newsletter it's OK as I am only reporting
hearsay" since it is not attributable to any person or company, and is
not to be construed as the official position of any person or company.
Consider it as a chat between 2 technicians. I have paraphrased his
words as I was furiously writing while he was talking, so this isn't
EXACT and I've deleted any names so this won't cause him trouble..
Question: What Chassis are affected?
Answer: CTC203, CTC197, and CTC195
Question: Does it affect only gemstar models?
Answer: In a way....those 3 chassis all use the same micro ( not the
same part#, the same capabilities ) whether they have gemstar installed
in them or not - the micro will accommodate gemstar......easier to build
them at the factory that way, rather than different micro's for "with"
or "without" gemstar, so all of those chassis are susceptible to this
problem whether or not gemstar is actually in the set.
Question: Why exactly does it occur ?
Answer: 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 XBR 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 XBR box does not truncate the data stream and
the extra bits get broadcast.....there is pending litigation on this,
the FCC and EIC is involved since they regulate what goes out over the
airways.
Question: Why does it just affect RCA's ?
Answer: Well, it doesn't...Sony's Hitachi's and Philips are also
affected.....the Sony's dropout video when it occurs...the Philips have
the tint shift all the way to green, so RCA's not alone in this.
Question: Is anything being done ?
Answer: A LOT ! "QQQ company", (name deleted) is helping the "XYZ"
company develop software that will properly truncate the data stream. We
haven't been ignoring it. As a matter of fact, we're very near the end,
now...you're going to be getting MORE complaints about this in the next
few weeks as it's being beta tested - they have to "cause" the problem
during the testing to "test" the cure, so during this testing phase the
trouble will be occurring often....hopefully it'll only be another 3
weeks....
