Hello, I have a problem with either receiver or the directv service, when i change channels, there is a sound(pop) that comes through the main speakers/sub woofer. I am using the HDMI cables through the receiver, I first used the composite cable (same problem) all cables are new? All power for the TV (samsung ln40a550), receiver, and satellite is on the same circuit. Would a surge protection( Panamax product) help to solve this condition?
