Our Review/Thoughts

needed a female/female and male/male adapter to reconfigure connections but BUZZING SOUND from tv is completely gone

Solved: 60 cycle hum is goneProblem: When I installed Comcast cable TV box, when I plugged the HDMI cable into the Marantz, I got a loud 60 cycle hum

Volume control did not make it louder or quieter, and it happened when the Cable box was plugged into AC power or not

Apparently there was a problem with grounding although it looks fine

Called Comcast cable to send a truck - they spent 6+ hours installing a new cable line from the pole to the house to try to reduce the line noise

WORKS GREAT! - I had the issue of the horizontal lines on my projector generated image via a set of component cables
