Why is the 3M Projector image so dim?

What to do if the 3M Projector lamp does not illuminate, but the fan runs?
If the lamp in your 3M Projector isn't lighting up, but the fan is running, first ensure the lamp is fully and correctly seated in its socket. If it still doesn't illuminate, the lamp may be burned out and require replacement. Also, make sure the lamp change lever is correctly seated on the switch.
Why does the new lamp fail in my 3M Projector after replacing a burned out lamp?
