I have just bought an Onkyo TX-NR636 and its HDMI output shuts down after watching the TV for 5 minutes. Everything comes normal after shutting down the receiver for 2 or 3 hours. The audio is still working.

Sounds like a fault to me. I assume its not shut away in a cabinet where it might be overheating. Is there perhaps a 'sleep mode' enabled in settings?

You could try flashing the BIOS to latest version (if not already).
