Hi.
Looking for advice, having a hard time. I can only have video when playing DVD connecting via ARC no AUDIO. I can't even have Set up display on the TV Screen.
I will appreciate all the help.
How long is your HDMI cable and have you tried a different cable?
If you think you have properly connected your Onkyo to your TV with an HDMI cable less than 12' and you can't even see a setup screen from the receiver then you likely have a blown HDMI board. You can try a receiver reset. How long have you had this receiver? I suspect you have recently bought this receiver used. Is that correct?
On further research, I note that those receivers are known for frequent failure of the DSP chips resulting in no sound. Can you get sound with a device connected to your receiver? The other frequent failure reported with those units was HDMI board failure. it seems those receiver have a bad rap sheet.
