Bought this TV when Circuit City was going out of business about 3 years ago and last week all of the "Red" hues disappeared. Blues and Greens were fine. I went through all of the Set-Up procedures and noticed that the "Tint" button no longer functions (it worked fine before). This happens on all inputs (HDMI, SAT, ANT) Any ideas? P.S. I see from this Forum that Samsung Rear Proj. are a problem. Not good.
