Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.- What type of connection cable/ cord used to connect Sky box to TV?The choices are:1- Component cables: 5 wires between the tv and the device, these are color coded on the end and have a green, a blue, a red, a white, and another red cable.2- Composite cables: 3 wires between the tv and the device, these are color coded on the end and have a yellow, a white, and a red.3- HDMI: 1 wire between the tv and the device, this is a single wire and looks like a computer plug on each end, similar to a large USB connector.Thanks.

OK, have you tried to connect another HDMI cable in Sky box and TV as a test as existing HDMI cable could be defective?

Expert:  Shahid replied 1 year ago.
No, it isn't common issue with Panasonic TV, however, Sky box could send out audio noise, have you tried to reboot Sky box?
Customer: replied 1 year ago.
thought that myself, so I've turned my ps3 on and its doing the same thing… with the sky box off

This is odd, two different video sources/ devices give similar whining sound noise when hooked into HDMI input of TV indicates problem with in TV and HDMI processor chip seems causing this noise. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you, I would recommend to get different model at this time.I trust my input will help you out.
