Question about Multimedia Projectors
I have a benq ds550, recently when switching on the projector, the fan spins up, the light switches on, and briefly for half a second you can the benq symbol on a blue background, then the projector switches off the lamp, the fans keep on spinning and then after 50 seconds it powers down completely.
Then the status LEDS: the lamp led blinks green for 10 seconds and then switches off for 10 seconds, the power led stays orange.
I've replaced the lamp and still the same problem. The fan works, and no dust inside the unit.
