RCA CTC187CJ Color Missing
I've had a tv dropped off in the shop with a problem I've not seen before.
The on screen menu and channel indicators quit working and there's good audio and picture but no color. RCA CTC187CJ Chassis F31672ET Model Awaiting schematics. Any help appreciated. |

Did you do the tuner wrap rework?

Probably corrupted eeprom data. Has the tuner ground been performed
properly to service bulletin specification, then check the eeprom data, if corrupted replace and perform a full eeprom chassis alignment, including the geometry, gray scale, stereo audio process, agc, tuner alignment, etc. David Gary wrote in message ...

Gary:
The "schematics" are NOT going to be of any help with this. Check and verify that the OBT (on board tuner) ground soldering has been done correctly and more than likely the eeprom will have to be replaced and a full chassis and CRT alignment including the 125 channel tuner alignment done. You will save a lot of alignment time if you have a chipper checker??? I would guess that you probably do not, otherwise you would have already done all of this. This is a classic symptom for this and other similar TCE chassis numbers. You should go to the website for this newsgroup at http://www.repairfaq.org/ There, with some searching you will find much specific information regarding this including troubleshooting tips, repair procedures, component testing methods, and important SAFETY information. Have fun.... and good luck with your repair. -- Best Regards, Daniel Sofie Electronics Supply & Repair\ ---------------------------------- "Gary" wrote in message ...
