I have my receiver hooked up to my TV cable and surround sound. When I run everything through the receiver the HDMI input cuts off after about 30 seconds I was watching TV. I have tried using all the HDMI inputs and it does the same thing. I tried resetting the receiver with no luck. When I turn the receiver off it'll work for about 30 seconds more and it will cut out to a the TV screen blank indicating only the HDMI input being used.
