Frank
I was reading this response of yours and I was wondering if what you were
saying
applied to my set too.
The Sony that I was working on was a KV32S10 that has sound and high voltage
and can
change channels too
but no video!
We also have no schematic but from the hints we went ahead and changed IC 301
with
no effect!!
We can also vary the screen voltage with no effect.
I don't know if my set has the IF pack you speak of??
Do you think that the problem that you described could be mine too??
Sorry to but into the thread.
TIA
