| Re: Do LCD RPTV Bulbs Go Bad?
Front projectors typically have lamp life rated for about 2000 hours. RP systems are typically several times longer due to the lower power ratings on the lamps. There is a drop in output through the life of the lamp and more severe just before the lamp fails, but it would generally not be noticed at 25% of the life of the lamp. If you are seeing the picture degrade, it is likely due to needing some cleaning in the light path on a 3 chip system.
