I'm working on a Sanyo DS25204 (chassis 25204-01) made in 2004. I have ho
vertical but high voltage and sound are OK. I do not see a drive waveform out
of IC101 pin 26. I have isolated that pin from any shorts. I do not have the
exact schematic. Can someone verify that pin 26 is the vertical drive out of
this chip (LA76843N) or have any suggestions as to what could be wrong. I find
it strange that everything works except the vertical. TIA, John.
