My Infocus IN26, with just about 300 lamphours on the clock, works fine for ca. 20 minutes but then suddenly shuts itself down and shows me the ´broken/red light' symbol on the display. If i turn it back on after a bit, the projector is working again (but again, only for about 20 min.)

If the counter had expired, the projector would not even attempt a power up. You have other issues. How many blinks on the light?

This could be one of two problems I have seen with another model Infocus projector (they are very good projectors though)
The first is the video input. Make sure it is attached correctly at both ends of the cable.
The second, remove the dust covers and blow them out. The problem can arrise if the temperature sensor detects the air inside the unit is getting too hot. If you can see the sensor when the dust covers are off (it will look like a little lump of goo on the end of a wire) then just give it a wipe as well. If dust settles on those it can cause incorrect temps to be reported.
Hope that solves your poblem =)

internal error. if the lamp looks ok and it doesn't have many hours on it, it might be the power supply. the capacitors dry out and do not supply sufficient voltage. the in72s do have that problem.
SOURCE: Infocus LP 280 runs for 1 min then shuts down, runs again then
are the leds on the top lit or blinking? it could be the lamp, the ballast, or the fans. check the lamp. if there are black spots or bulges in the lamp, replace it. if not, make sure the fans are running. if they are, replace the ballast.
