this is a touchy subject for sony. basically sony has increased the brightness levels for the backlights to have better color tones in thier lcd's. well the downfall of this is the white spots you are experiencing. this is not a defect, you will never get them to go away, the only thing you can do is to turn the backlight and brightness down to reduce the white spots. if you contact sony, there is a software upgrade that will help reduce this issue...
