Thanks Randy. Yeah, I'm thinking this may warrant a new tv. It seems you read time and again that with the cost of repair (I'm not under warranty nor the DIY type) you may as well just buy a new set. FYI, the buzz when unplugged was coming from the lower part of the panel near where it plugs in. I imagine this is where the power supply rests, though not positive.
The Internet? Is that thing still around?
