I've been using this projector for about 6 months with no problems until last night. It was working fine for about 90 min, then the lamp suddenly dimmed to about half brightness and I could hear a buzzing noise similar to the sound it makes when the lamp is first starting. I immediately shut it down for about 5-10 min. After powering it on again it worked for about 55 min before doing the same thing.
The lamp was used when I got it, so I don't know how many hours are on it. Does this sound like the lamp may be failing?
I've seen two of these projectors with bad power supplies and only one with a good power supply (this one). Are there any known causes for the high failure rate? Is there anything I can do to prevent it? Both of the bad power supplies had a burnt out inductor and shorted power MOSFETs in the lamp supply. It uses the same power supply as the XG-E1200U and XG-E3500U.
I have the projector apart right now to clean the filters and check for obvious problems. Andy Cuffe
