RCA CTC203

[Vince]

Hi!
Has anyone ever figured out what causes this set to loose sound and you
unplug it and plug it back in the sound is back?

Do a search...Google it.

Vince,
This has been an "over-active" subject on this very newsgroup for the last
month. Do a google groups archive search, you should find quite a few
relevant threads just a week or two old.

Thomson Technical Assist tells us it is normal, that they are working of a
fix for it, and that it has been a symptom or RCA/GE since the early CTC-19X
series of chassis.
There are a few viable workarounds including jumping a cap from a certain
spot to ground but that disables other features designed into these sets,
inclusive of the Guide Plus and Closed Caption.

I found a bad solder at the base of the input transistor in the muting
multivibrator of a Ge with no audio. Just like this symptom it muted
randomly and it would work after being unplugged. Might be unrelated.

A*s*i*m*o*v

.... Which sparks some mnemonic circuitry.

Asimov what is the part location of that transistor please
for my files just in case.
thanks

According to several posters here and the clients that I have done it for,
the cap fix may not disable the guide functions. I does seem to disable the
CC.

It depends on the specific chassis, system control, and Gemstar
application that is in the set. Some of the designs, it disables the
entire set of features, others just the CC.

All of us who have been dealing with this issue since the late 90's
when Gemstar first started showing up in the Thomson tv sets are all
aware of the many different design implementations.

Oops, wrong info! Just checked it was a Magnasonic not a Ge.
