I have an XR-10S that when you turn on, the power indicator light stays solid green. Then, the projector lamp bulb indicator light will come on green and then go off. It will do this 3 times but the lamp fails to come on. Next the power indicator light as green and the lamp indicator light red, flash alternately for about 20 seconds. Finally the power and lamp indicator lights both turn red and stay solid. The manual doesn't seem to describe this sequence. The end result is that the projector lamp doesn't come on. I'm trying to figure out what this sequence means. Any help is appreciated. jgeorg
