Samsung Plasma Causing 60HZ Hum in HT System

Hey - I have an issue that is driving me nuts.

I have a 58" Samsung Plasma TV from around 2009 or 2010... still works great.

I recently moved and replaced this TV with a 65" Sony 4K TV and relegated the Samsung to the master bedroom.

In the past, I had not hooked the Samsung up to a HT receiver. However, in our new house I now have it hooked up to a Denon receiver. Whenever the TV is displaying anything, I am getting a fairly loud hum through the HT speakers- regardless of the Denon's volume setting.

The hum exists even when I remove the HDMI cable connecting the TV to the receiver. If the TV screen is blank - no hum. If the TV screen is displaying anything.... hum.

I have replaced all the power cords, no luck there..The TV and receiver are normally plugged into the same power strip... hum

I have plugged the TV into an outlet on a different circuit... hum


I am about out of things to try.... and am open to any suggestions before I smash this thing to bits!
