RCA CTC203

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.

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.

... Which sparks some mnemonic circuitry.

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.
