I have had this projector for a few months, it works fine in the sense that it successfully projects an image on a screen. But a purple hue has infested the top left corner, and a green hue is in the bottom right corner, resulting in brightness/contrast/color loss. I'm not exactly sure how many hours are on the bulb because it is not with me at the time. Any suggestions as to what it may be? Thankyou! -eric
