I replaced the tuner and the sound returned.  This set has PIP with two
tuners.  The Sony part # for the correct tuner in this repair is
8-598-542-20.  If you look at the SM for this set, the L & R audio comes
directly out of the tuner.  I tried just replacing IC02 in the tuner,
but that did not work.

Replace the tuner. Or at least sub it. I have seen the tuner cause no
audio
even in the video mode on Sony's.

This 5 year old Sony has no audio on tuner or video 1.  I input a signal
into pins 7, 8, 10, and 11 of the audio amplifier IC402 (TDA8580) and
got sound on the speakers.  I also confirmed a B+ of 24 volts going to
the audio amp at pins 3 and 15.  I am suspecting the jungle IC, but need
the SM to confirm.  Thanks.
