My tv has had a rather peculiar problem in the past. I bought it from a friend and occasionally the set would whine at a fairly high frequency whenever the screen was too "hot" - if the picture was too white. I have reconfigured the settings according to the Video Essentials calibration DVD and have not had the problem since. I would like to know why this had originally happened.
Also, I unfortunately fall into the minority of people who can hear the high pitched whine of all the tv's when I go to the store. Does anyone have any experience in reducing this whine on their own sets? I would love to be completely rid of it altogether. I would appreciate any insight to this. Thanks....
