I've had a 2300MP for a few years now. My first bulb lasted over 2000 hours, and now I'm on my second bulb (600 hours in). All of a sudden, now, when I turn my projector on, after about 5 minutes the video starts to flicker, and then after 30 seconds of flickering, what I can only surmise as the BLUE color disappears completely leaving a sickly green picture. As I have said, it worked fine for years until recently. Could this be the result of a faulty bulb? Or am I looking at a deeper hardware issue? (I use this projector a lot, and have all 3 inputs connected. My connections are solid, and the color issue spans the 4 input source screens.)
