Why is my device constantly overheating?Lately, my Optoma HD 20 has been getting really overheated a few minutes after powering up. It hasn't always had this...
Why is my image grainy and out of focus?When I turn on my Optoma HD 20 projector, the image appears blurry and out of focus. What can I do to fix this?
Answer to "Why is no image being display from the projector?"The way I see it there are two possibilities. 1.) Your HDMI cord is either not plugged in properly or it is broken. 2.) The bulb in your projector has burned out. This can be caused either by overheating or overuse. The standard bulb life for these projectors is 3000 hours in high lamp and 4000 hours low lamp. If your bulb is burned out it will need replacing, and a new bulb can cost you around $250.
