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.
