I had the light engine replaced the first week i owned it but, that was 4 years and it's been great ever since.
ISSUE: I am now experiencing picture "strobing" and color problems. the strobing is hard to describe -- it's like a brightness 100 to a brightness 90 and it's constantly flickering. the colors are "aliased" looking -- like it's having a hard imaging gradiations of a color and just giving me blocks of unsmoothed colors. there are no nosies or indicator lights associated with this issue.
WHAT I'VE DONE: * changing inputs doesn't matter * i replaced the lamp today (old one had 5000 hours on it) -- still the same problem * i purchased a new color wheel -- but i am reluctant to install if it really isn't the issue.
