    Is there a way to reset the lamp timer without seeing the menu. I just replaced the bulb in my projector, and now every time I turn it on, it powers off before I can get to the menu. Any ideas about what this problem could be?

      Hi Emily,
      Your remote control should have a MENU button. Pressing that will bring up the menu on screen. Your projector is turning off because it thinks it is out of lamp time. Turn on the projector, it should give you just enough time to press the remote control MENU button and Scroll down to Management Menu/Lamp Reset and press yes. That should do the trick. You can also try doing a factory reset
      The manual can be found here
      You may need to contact them to find out the button sequence for resetting the lamp timer through the remote or on the projector.
      We have more experts over at our You could join and there maybe someone who knows that sequence.
      Good luck. Please let me know how everything works out.
