I have a two year old Wharfedale LCD37F1080P television that I have recently inherited. The problem is, there is an intermittent buzzing noise that is driving me mad. Here are the facts:
- I have no set-top boxes or other gizmos attached. I just watch Freeview using my standard coaxial cable and the built-in digital receiver.
- I've adjusted the brightness etc, but it makes no difference.
- The buzzing always comes on when I change channels, usually stopping after a few seconds before starting again soon after.
- The buzzing usually starts and stops at times when there is a definite picture change on the screen (though sometimes it just goes on and on).
- The buzzing is still there when I remove the aerial from the tv completely.
- Turning down the volume makes no difference, but it stops when I mute the sound.
If anyone has any suggestions I would be very grateful.
