Hello folks- The Guide + menu on this set keeps coming on by itself
when connected to cable. At some point it will go into the audio menu and mutes the sound. While the menu changes on the screen (all by itself) I can't use the front controls. Is this a typical Gemstar going south ? If so, can I simply disconnect it and use the TV normally without the Guide + ? My customer doesn't care about this feature. Thanks Bill |

This may also be an issue with the data the coble co. is sending, or the EPROM.

The Gemstar4 module is the entire system control in the later CTC203 sets,
without it the set simply will not function at all. FYI early Gemstar 4 modules were so bad in failing that a very large number of them were replaced under warranty. David Bill wrote in message m...

I just got one in that doesn't have U13101, which I assume is totally controlled by the Gemstar unit. Came in with no power. The customer first noticed that the set would loose video, but the audio would stay. : FYI early Gemstar 4 modules were so bad in failing that a very large number : of them were replaced under warranty. This one was manufactured March, 2002, and the dealer said that it is out of warranty. Chassis # CTC203AA9, model # F27669. There is no data on any of the Gemstar connections, or pins 5 and 6 of the eeprom when the set is plugged in. Is there any way to determine that the Gemstar is the culprit? All voltages from the SMPS are fine, and the 12 volt SMPS regulator works when Q14104 os bypassed. Any ideas? -- Tedd Doda VE3TJD remove: lose.this. to reply directly. |

Update: I decided to take the Gemstar unit apart, and found that many of the 34 pins coming from the main chassis were very badly soldered. I reflowed all 34 pins and the set is up and running once again! -- Tedd Doda VE3TJD remove: lose.this. to reply directly. |
