Yamaha has totally ignored my 3 requests to provide a schematic (someone
claimed they charge you $18 anyway). Yamaha audio sets are not in Sams.
Someone suggested I checked the crystal (remote receiver not operating). I
don't believe an IR receiver uses a crystal. Surely, someone has a schematic
for this set. I will be glad to pay costs, of course. Thanks for any and all
help. I'm stuck without a schematic.

Regards,
Dave
