Hello all. My Z5 is getting some high hours on it and the bulb is starting to dim in the middle of a gaming session or sporting event to half the brightness or less. The "Lamp Replace" light comes on sporadically too. It has over 2000 hours on it so im figuring that the bulb needs replaced. Any ideas on where to find one at a descent price? I checked Ebay and couldn't come across one. Thanks for any input.
