Hum in your system

If you have a system that is in some way attatched to your tv, whether through coponent video or s-cable or whatever, and your tv has cable; try unpluging the coaxial cable from the wall outlet; turn on your amp or receiver, and the hum will be gone. if this works, call HomeTech Solutions at 408-257-7152 or www.hometech.com and get part #XA-63400 ground breaker for $7.45 plus shipping, and it will eliminate your hum. It really works, and I don't work for them. I just had a hum problem and tried everything. je
