I have installed my new Yamaha RX-V650 receiver according to the manual. I have the receiver feeding the VCR input and the VCR output back to the receiver as shown. I get no signal out from the receiver to the VCR. I have tried everything I know in the system setup but no luck. All connections are of the same type so it is not a conversion problem. Everthing works correctly when I play a recorded tape on the VCR. Any help will be much appreciated.
