I connected my cablebox via HDMI to TXxx509 , how can I watch TV without turning on the receiver?
I connected mine to the receiver so that I would get the dolby and surround. Sound from all the speakers. With the txnr509 you can set it up to come on and off whenever the tv is turned on or off. If you can't set it up, just call onkyo and they will walk you through it. If you don't want the sound fron the receiver don'°t connect the HDMI to it.
