Hey folks....I hope some one can lend me a hand. I've had the 950/7100 set up for about 1/2 year now. I love it!!! There is only one thing that I can't figure out. Now that we are in the DRY mid-western winter time....anytime I touch a light switch or plug anything into another electrical outlet in my theater room, my audio drops out for about 2 seconds and then restores. I don't hear any clicking or switching from the unit when this happens. Is this some type of grounding issue??? What can I do to resolve it. Thanks in advance for your advice.
