Typically hum is caused by ground loops. TVs usually don't have grounding pins on them but the cable line going straight into the TV (if that's how you have it hooked up) can cause the hum. The cable box, if that the way you do it instead, could have problems. Replace it if you can.

It is possible that there is a some line noise somewhere that causes that hum and a power conditioner would probably get rid of that. I doubt changing the surge strip would do anything unless the old one had some serious problems in which case it should be replaced anyway.

Is the other outlet you plugged the TV into on a different circuit?

thank you for that info.
