Buzzy plasma

["White, Peter" <peter.white@xxxxxxxxxxxxx>]

My plasma has started to buzz a bit during bright scenes, but not
noticeably
so when the screen is darker.  I assume this is a fault, but does anybody
know what causes it?  It's a series 5 Panny, getting on for 3 yrs old, but
only been used for 1.5 of those years.  Still under warranty.

Thanks


Pete
