It's upsetting. I love our 28" Toshiba Picture Frame "Flat" screen CRT Telly. I refuse to let it go on grounds of rendering of motion and SD picture quality. I have developed tittiness and wonder if the humble telly caused it. One day on a hunt with a spectrum analyser app I pinned it down. It's there but I cant hear it except the odd occasion when I turn my head a certain way or maybe it's resonating a lower frequency somehow....? Changing a flyback transformer with 35kV is a bit deadly. Maybe a noice cancelling speaker placed in or near it...
