Report "I have Optoma PK301 DLP Pocket Projector. Now, when I switch on the projector on left side of the screen there appear small white spots. Sometimes those white spots turn to black as the time passes. It really makes the images blurred. In the white background they look black and in the darker background they look white. What do you advise me on this issue? This is only five days that I am using this projector since it reached me on the 24th January. Your timely help will be highly appreciated. I await your reply. Thanks in advance"
