White dots on projector screen

This question is not answered
Hi, since few months ago, my 2 years old 4210 projector has shown hundreds of white spots. It started with few dots and growing rapidly. It is not dust because I tried to blow them and none of them dissapeared. I checked the lamp and couldnt see any dust on it. Does anyone else has experience this kind of problem ? The projector warranty expired 4 months ago. Any advise ? Regards, Alex

  • I've got the same problem. I have a 2400MP and i have a "dusting" of white dots all over my screen even in regions where the LCD doesn't reach. I just assumed it was dust somewhere but I haven't tried cleaning it off yet.
