When it rains it pours , my Mitsubishi HD1000U's giving me a replace the lamp message at 2380 hours, I fired up my X1 that has 3358 hours on it last night (keep in a camper and use for camping) and had line on right side of machine that research at AVS shows to a failure of the Light Engine? (or some such)... dang, I was going to order lamps for both... now trying to decide whether to get a new lamp or Upgrade to the HC1500... going to go out and clean the color wheel on the X1 now... JIC...
