I bought a 27 inch analog FS120 Sony tv. When I first turn it on the picture comes on very sharp and clear and about 10 seconds later it is like at the snap of a finger the settings change and the picture gets much brighter and a little hazy. I swapped it out and this one does the same thing but my current tv does not do it. Some channels still come in very good but no matter what channel it is on when you start it up it does that. Has anyone else had this problem or have any suggestions?
