HELP: gound hum from TV even while off

Posted by Mart on December 31, 2000 at 20:14:15:
I get an odd ground hum problem. I say odd since it's not 60hz. It' a -30dB 30hz beat & a steady -50dB 120hz. Right now it's so deafening I'm using my Panasonic SF27" TV's cheapo internal speakers. I'm thinking of trying Mondial:Magic but can't determine source. I'm using high end shielded cable. Can the RF cable contaminate the signal even while the TV is off? I unplugged the RCAs & saw a definite spark.

....just my 2¢
