Why won't my NEC NC900C turn on?

  If your NEC Projector won't turn on, first ensure that it's receiving AC power and that the main power switch is in the ON position. Also, check if the panel key lock function is activated, as this locks the control buttons. If the internal temperature is too high, the projector's protective function might prevent it from starting; wait before trying again. Finally, if you're using the projector at a high altitude (5500 feet/1600 meters or higher), the cooling fan settings may need adjustment; contact your dealer/distributor for assistance.

How to fix a blurry image on NEC Projector?

  If the image on your NEC Projector appears blurred, ensure the lens is properly focused and that the screen and projector are positioned at the correct angles. The projection distance might exceed the focusing range. If the projector was stored in a cold place and is now in a warm environment, condensation may have formed on the lens or internal components; wait for it to dissipate.
