Sharp 56DR650 56 in. HDTV DLP TV

I bought the TV in November and it had excellent color and picture. Unfortunately, the color engine made a loud humming noise. We contacted Sharp and they were very good at getting our TV to a repair center. The repair center changed out the color engine for one that was misaligned. The repair center ordered another color engine. This took almost two weeks. They then delivered the TV back to us. The picture was good for about 15 minutes and then everybody turned into the Hulk. Skin tones turned green, blue skies were purple and the colors bled horribly. Again we contacted Sharp and the repair center came out and picked up the TV. They have had it for a week and notified us that the color engine is on back order. I have not had a lot of luck with this TV, hopefully that is not the case with all of them.
