RCA CTC185AB dead
I was givin this TV in the respect that I could fix it. its a nice 27inch TV
set with the notorious ctc185 chassis in it. The reason I took this on, because I have successfully repaired the same exact TV that had a bad flyback, HOT, regulator etc... its still working to this day. this one just gives 3 pulses, no startup. sounds like HV pulses. I checked all the major components, including the regulator circuit, and found NOTHING shorted. So hopefully the flyback didnt fail on this one. (probably did) the B+ on the hot varies from 164 to 168vdc. in standby. As soon as I hit the power button, the B+ shoots up to 200vdc. Any ideas? Im thinking regulator. Again. |

Best start with the reg section plus ESR the caps ,then the usuall trouble shooting procedures . Those sets can be sods to work on... Good Luck kip |

RCA has put out some real junk and some even screwier circuits. r -- Nothing beats the bandwidth of a station wagon filled with DLT tapes. |

You need to order the new regulator transistor that comes with about 10 other
parts to repair the problem. It's cheap and easy. I don't have the part number here, but if you order the regulator FET it comes as the correct kit. About $7-8 |

Be careful NOT all CTC185,s use the Kit.

The kit is RCA 231523 good for ONLY CTC185A/B/C/D/M/N/AA/AB.

6 dollars. Hopefully thatll fix it.
The last one I did, I had to buy that kit, and a new HOT, and a new flyback. "john" wrote in message .. . The kit is RCA 231523 good for ONLY CTC185A/B/C/D/M/N/AA/AB. kip |

kip Right, I should have mentioned that fact. Also quite a few CTC185 have yoke failure and CRT with no vaccuum. (probably a secondary effect of the yoke failure). Ron |

it has vacuum. I can see the getter, it appears normal.
