Our Acer PD723P Data Projector starts up normal with full light output but after a minute the projector shuts down and the red warning indicator for the lamp starts blinking fairly rapidly.

Strange is that this happened out of the blue. Projector was working normally last time, next time this happened. Cleaned the filters and the inside of the projector. Lamp bulb does not look burned. Fan sound can be heard, so I presume the fan is running.

The projector is about 7 years old but not often used, certainly not for long periods of time. Mostly for our non-profit presentations. The last few months I also use it occasionally to show cartoons on the wall for our grandchildren, but that is also limited to 2-4 hours a day max, maybe 1-2 times a week. So lamp hours are way below the 2000 hours given, but then again the lamp's age is 7 years.

What bothers me is that this came without a warning. This was not a slow go-down but a one second to next failure at START-UP. Compared with the full light output at start-up, I am wondering if this really is a lamp problem or maybe a power source problem?

Maybe not related,but we live in a restored historic building and we have a more than normal amount of light bulbs (normal 60-100 watt daily stuff in kitchen and hallway) blowing out, especially the new ecolamps.

UPDATE: removed the lamp, seems OK, not burned or so. Cleaned the insides of the projector with vacuum cleaner and pressured cleaning air spray can. When I start with a completely cold machine, I just have enough time to see the screen coming up and even push the menu OSD, but before I can do something else (like checking or resetting the lamp time), the lamp switches off and the red lamp warning light comes on blinking constantly.
