I've had this TV for about a month now and have noticed that the top third of the screen is slightly darker than the botton two thirds (no matter what source I use - DVD, satellite or VCR). It's like the top part of the screen is tinted. This is most apparent on scenes with a lighter/brighter background. It is not noticeable in dark scenes or ones with alot of action/colors. I'll also see it when there is a vertical panning of the camera angle - eg. following a golf shot in the air. I contacted an authorized Sony TV tech and he could see the problem too. However he stated that it is a design flaw with the tube and nothing could be done about it. Has anybody else noticed this problem? Can it be fixed? Any advice would be appreciated.
