Why does InFocus ScreenPlay 72 projector warn me to replace lamp?
The projector lamp life has been progressively getting shorter, and doing so more quickly the last year or two (unit was new in 2006). Now it's to the point that a brand new lamp still yields the "Replace Lamp" warning message. Rated life of these lamps is 1000 hours, which I understand is the ideal case, but it has been a significant decline. The last lamp didn't even last 100 hours.
In my research, I've found that many projector owners (of many brands) complain about reduced bulb life on older units, and the general consensus seems to be it's a power supply and/or voltage issue. One person mentioned specifically that InFocus had told them the warning message comes on when insufficient voltage flows through the bulb (as a bulb wears, this would happen anyway).
Any way to diagnose if this is the case? Can the power supply be repaired in a unit like this? I am otherwise very happy with it, and would hate to have to replace it.
