ITC008 RCA 36V550T.
Sorry, posted before I was finished!
No sound on tuner, sometimes sound is there just as pix apperars, then goes. Ok on inputs. Replaced CS124, as per service bulletin, the same. Looking on the service cd, the schematic is wrong! Pin 47 of IC # IS 100 shows audio input from sound IF TS 101 transistor, with 1.5 vdc, but there is no connection on the IC in the set. It may even be the Micro not switching the sound portion of the tuner signal. Anyone see this problem before? Sky. |

ITC008 RCA 36V550T.
Not with this particular set, but I had the exact type problem with a
video processor (Toshiba). The replacement IC schematic had connections where there were none in the set. I posted this problem and asked for feedback if common problem, but no replies. Good luck. |
