What happens when you select 'receiver' and use that power on/off option? Also, how is the AC connected? Are the respective components plugged into a power strip independently?
Performing a factory reset of the receiver after unplugging the HDMI cable might work too.
I have a Panasonic Viera tv and a Pioneer VSX-822 receiver connected via HDMI cable. Turning on the tv powers up the receiver, but the receiver will not turn on by itself. I would like to listen to music without having the tv on. How can I do this? Thanks for any help.
