I bought an LCD TV for my basement not too long ago, and decided to hang it on the wall. Since it was goign to be on the wall, I wanted to put the A/V accessories in a cabinet in the corner of the room. I ran 2 sets of component cables, 1 S-Video cable, 3 stereo audio cables, 1 coaxial line, and the power cable for my TV. These are all roughly 15' in length. I have a dropped ceiling in my basement, and ran all the wires together. I did not see an easy way to hide the cables in the wall, so I have some black tubing to keep them together (I know it's not the most professional thing in the world, but I'm not a professional).
The problem I am having is that no matter what input my TV is set to, I have noise in my speakers. It sounds like wind blowing, and when I turn the volume up or down, the wind stays the same volume. When I mute teh speakers, the wind stops. While trying to find the source of the problem, I turned started unplugging cables one by one to see what made the noise stop. It turned out to be the component cables from the cable box to the TV (specifically the green cable...when I unplugged the red or blue individually the video distorted, but stayed, and the sound wa sstill there. When I unplugged the green, the sound and video cut out altogether).
I assume I am getting this noise because, like an idiot, I ran the power cable right along the component cables, and they are not shielded well enough. What would be the best way to eliminate the noise? I'm only assuming this is a problem between the power and component cables, but I am open to suggestions, as I'm sure the majority of the people who frequent this forum know more about this than I do.
Thanks for any help you might be able to provide.
