TV sound buzzing

[alys2please]

I have a Panasonic LED tv which has recently started to buzz. When I switch source to DVD for example it stops so I know it's not the TV but how do I stop the annoying buzzing. We patch Sky through to it but I've checked the sound configuration on the box and all seems normal. When I pull the aerial out the back it stops buzzing. HELP!

What input has the buzz? You said the TV sound buzzing, but then the DVD input is fine, so it's not the TV itself that has that issue. Did you try different cables?
