Hi, I just got a new Sony Bravia TV and I noticed that every time I change from a SD channel to a HD channel the TV makes a very short high pitched noise. The sound is a bit like a dog whistle but very sharp and high pitched.
Can anyone help solve this please.
Hi there,
Welcome to the Sony Community.
So I can try to help, could you let us know the full model number of your TV?
Best wishes,
