Hi

I have a Marantz NR1501 with Sky, Apple TV, and a Panasonic DVD all running through a Belkin Pure AV power box.
On morning when i switched it on i had lost all sound. I returned my amp to the store and it got repaired. When i got home and turned it on it still didn't work so we went back to the store and after testing it they gave me a new amp.
Just to be safe i bought new HDMI cables and set it all up. After a night of great sound i switched it off using the button on the Belkin box.

In the morning when i switched it on again i had lost all sound again.

In the store when we tested the first amp there was sound on components just not on HDMI, Does anyone have any ideas what could be causing this.

Thanks
