Just got around to unpacking and setting up this receiver last night. I was watching a DVD and it only played for no more than 10 minutes, then "Poof", the 430 turned itself off after making that sound. I turned it on again, this time it lasted maybe 10 seconds, then "Poof", and it turned off. The light around the standby button is still lit amber like it's supposed to. It seems like some sort of protection measure being activated, do you guys agree? Any ideas are appreciated.
