Ok, tried to search the forums, didn't see anyone else with the same problem..... I have two HD Tivo boxes hooked up to one Sanyo HDTV set. One of the boxes are running on HMDI and the other is Component. TV only has one HDMI jack. Doesn't matter what box I have the HDMI hooked up to I get a loud popping electricity sound when I change the channel or pause the show. Doesn't happen with component cables. I know my TV's HDMI port and the HDMI cable are good. Tried it with another HDMI cd player with no problems. Any idea what the problem may be? Thank you so much!
