The importance of NEC NP-P350W projector lamp

While generic lamps may be sold at discount prices, their inferior workmanship and cheap materials often result in damage to the interior of projectors. They are also prone to explosions which can release toxic heavy metals into the air as well as damage your projector beyond repair. Read more about the 7 Ways to Spot a Counterfeit Lamp.

    • OFF: Default setting for 100% brightness
    • Auto ECO: Lamp power consumption is controlled by the projects and will change between OFF and ECO1 automatically according to the picture.
    • ECO1: Lamp consumption set at 75%

    • Select SETUP
    • Scroll to GENERAL
    • Scroll to ECO MODE.

  1. I need help! Our church has two NEC PA350W projectors. I just replaced the bulb in one unit, and three lights are on: red, orange and green. I cannot get the unit to power up, neither by remote, nor pushing the power button. Can someone give me some advice? Thanks so much.

      Hi David,
      A steady red light is indication that the lamp has been changed but the lamp timer has not been reset. Did you complete this final step? If not, complete the reset of the lamp timer and the projector should turn back on.

      A blinking red light of 5 seconds on and 2 seconds off means the lamp cover has not been re-installed properly. A steady blinking red light ( 5 seconds on, 5 seconds on) indicates a lamp that is not firing. You can turn the projector off and then on again to see if its self-corrects. The other reason for a steady blinking light is a lamp that has reached end of life. Since you replaced a new lamp into the projector, it’s probably the need to reset the lamp timer.

      The orange light usually means the CONTROL PANEL lock has been turned on. The green light showing means the projector is on standby.

      Try re-installing the lamp. It may be out of alignment and not reacting to the other parts correctly. Did you buy an authentic lamp because sometimes the counterfeit lamps don’t have the proper connections and the projector will not turn on after installing the lamp.

      Hope this helps. If you continue to have trouble, consider joining our forum ( where this is a community of experts to help you solve the problem. Good luck and let us know how things are working out.
