I read your review on the z5 and it was impressive , out of box , however I have one with 80 hrs on it and have noticed big color variations especially on a white screen,,, the left 1/3 of he screen is pinkish ,, the middle 1/3 is white, right 1/3 has selected pink splotches , the first time I called about they said to sent it in to be checked out,, then I called again for another problem and they said it was within 10 percent of variation limits, anybody had this problem? Quite noticeable on white scenes, I have more hours adjusting this thing than watching movies, any suggestions?, other than spending 500.00 on calibration which may or may correct the problem,, they also said they had never herar of any lens cover problems, I had a lens cover closing issue due to a piece of metal that came unglued and got stuck. Anyone else had any problems?
