    I installed a new lamp on my pro350 optima projector. When I turn on the light goes green and immediately turns red: no light from lamp. How am I suppose to reset lamp timer if no light to see projection?

      Hi Joy,
      Two things can be happening:
      1. The lamp was not installed properly. Try taking it out an re-installing making sure all the connections are secure and that the lamp screws are not too tight.
      2. The lamp maybe a counterfeit that wasn’t properly calibrated to the projector’s optics so the projector can’t read it. Where did you buy the lamp? Was it from an OEM manufacturer? I would contact them and ask for a new lamp or a refund.
      Hope these suggestions help.
      Regards,
      Shelagh
