Just wanted to add -- My Mitsubishi 52" LCD's power supply radiates even when the display is turned off. Physically unplugging it from the wall is the only way to see the RFI disappear. Other power supplies, such as for wifi routers and other "wall-warts" will also be "on" and doing their thing even though the device itself is in an off-state. Good luck on finding the source of the problem!
