A:Answer I have the same problem!
I bought this unit 2-3 years ago and suddenly two months ago I couldn't get a TV audio connection. Everything that required streaming thru the TV video didn't work....TV, DVD, and the on screen settings menu. I changed the HDMI cable, swapped TVs, and even changed out the receiver board that contained the HDMI receptacle. Nothing helped. Only thing that works now is the radio. Big Deal.
Ironically, I bought two of these Sony receivers because they were less than $175.00. The other one still works good.
Let me know if you ever figure it out.
