Annoying humming noise with composite video

by luctheduke161 / December 25, 2005 8:22 AM PST

I have recently hooked up my Sharp LC-37GB5U to a SOny progressive scan DVD and an annoying humming noise now comes over the home theater that I can't get rid of . . . does anyone have any ideas?

I've tries a different DVD player, no luck in getting rid of the noise. The video cables are Moster, so I've gotgood cables. I've turned off all other electrical devies on the circuit, no luck. I need some ideas.

Power could definitely be causing the issue. Make sure that all of your components are plugged into the same power supply/power strip.

You mentioned using the same power strip . . . I just put a Monster HTFS500 on the TV, a Monster power strip on the reciever and another Monster product for sub woofers on the sub woofer. It seems to have help for everyuthing but the subwoofer, which still hums. Is it really important to put them all on the same power strip?

Also, the model number sounds like an LCD TV, why are you using composite video? Go component or digital, you will notice a difference.
