&gt; &gt; Larry...
&gt; &gt;
&gt; &gt;   Why not resolder the main tuner and
reinstall
&gt; it?
&gt; &gt; I find that most Sony tuning problems I see
are
&gt; caused
&gt; &gt; by fatigued solder in either the
tuner(mostly bad
&gt; &gt; grounds to the tuner body) or the
&gt; IF/AGC/AFT(mostly
&gt; &gt; dry joints at coil pins).

&gt; &gt; &amp;gt; I am working on a Sony KV-32XBR45
set.  It
&gt; came
&gt; &gt; in
&gt; &gt; &amp;gt; intermittent. Pix would
&gt; &gt; &amp;gt; flash &amp;amp; go off with sound
doing likewise
&gt; for
&gt; &gt; about
&gt; &gt; &amp;gt; 10 minutes, then seem to
&gt; &gt; &amp;gt; work ok.  Found that tapping on
main tuner
&gt; would
&gt; &gt; &amp;gt; simulate problem.  Main
&gt; &gt; &amp;gt; tuner is a 8-598-254-40  &amp;amp;
sub tuner is a
&gt; &gt; &amp;gt; 8-598-047-01.  After removing the
&gt; &gt; &amp;gt; "A" board &amp;amp; tuner &amp;amp;
reordering
&gt; &gt; connections I now
&gt; &gt; &amp;gt; have a permanent no pix or
&gt; &gt; &amp;gt; sound , just snow &amp;amp;
garbage.  Will any
&gt; other
&gt; &gt; tuner
&gt; &gt; &amp;gt; sub for the main unit?
&gt; &gt; &amp;gt; Does anyone know if a 8-598-431-00 
will sub
&gt; for
&gt; &gt; the
&gt; &gt; &amp;gt; main tuner?  I have a
&gt; &gt; &amp;gt; good one of these.   Thanks   Larry
