I've just bought a new Philips widescreen TV (24PW6518), and it causes "listener fatigue" watching it for long periods of time because it makes a constant high pitch "tinnitus" like sound. I can't stand it, and have stopped using it. An engineer came and couldn't find any fault. I am now thinking of getting rid of it, because it causes discomfort to watch TV. Can anyone please recommend a small widescreen TV (either 24 or 28 inch) that has decent sound, that won't make this high pitch "ringing in your ears" sound? (Am I right in thinking that LCD TVs are silent in this regard - maybe I ought to get one of these?) Thanks, regards, Robert.
