Go with authentic lamps

Your Optoma Theme Scene HD65 uses the Optoma BL-FS180C projector lamp and in order to keep your projector working at its best you need to always install and authentic lamp. Generics have inferior parts so are prone to overheating or exploding.

Often these lamps use toxic chemicals as substitutes and can’t be calibrated properly to with your projector’s sophisticated optics. Keep your projector working and go with an authentic Optoma BL-FS180C lamp.

Always look for the seal of approval and watch for telltale signs you are about to purchase a counterfeit lamp:

    I have replaced the bulb per the instructions above. When I plug things back in, I get no power for the projector. Is there a reset button?

      Hi David,
      First check that all the screws are tightened and that the projector lamp cover is securely in place. If it’s loose at all the projector won’t turn on at all. You can double check the connections on the projector lamp as well. If you bought a cheaper version of the lamp off a website such as Amazon and it’s not a guaranteed authentic projector lamp, then it maybe the actual lamp is a dude. That happens quite a lot with counterfeits. The last thing to check is the projector lamp timer. That must be reset to zero using the online menu or remote control. This lets the projector know that the new lamp has been installed and it’s ready to work. Hope this helps. Good luck

    So glad I found this page, it even has recent activity! Im just ordering a genuine projector lamp today, hopefully will get to me by next week.
    This guide is exactly what I’ve been looking for and even has the model number for the lamp needed.

    I bought the lamp and replaced it but the screen only comes on for a few seconds then the lamp light lit red?

    • avatar Shelagh McNally says:

      Hi Kane,
      Did you reset the lamp timer? It sounds like the projector still thinks the lamp has reached end of life. You need to set the lamp timer back to zero to turn off the lamp light and get the projector back working. Hope this helps.

        It doesnt stay on long enough to go into the menu to reset is there another way of resetting it?

        • avatar Shelagh McNally says:

          Hi Kane,
          First thing to check is that the lamp has been installed properly. Check that the screws on the lamp are tight enough so there are no loose connections. The projector will not turn on if the lamps is not installed correctly and sometimes this is as simple as the screws being too loose. The next thing to check is that the lamp cover is also properly connected and not loose. If that still doesn’t solve the problem, then try taking the lamp out and re-installing. Check that the air filters are not blocked as well -this can also cause the projector not to turn back on. You can also try accessing the reset menu from the projector rather than using the Menu button on the remote control. This should keep the menu onscreen long enough to reset everything. Hope this helps. You can also join our forum for more experts to help you out at

    A bit of advice from someone who installs projectors as part of his living: As soon as you get the lamp life warning (in whatever form it takes) RESET THE LAMP TIMER and shut it down then order a new lamp. This gets around the problem that some projectors have with shutting down before you can navigate to the menu when the lamp life is exceeded.

      Hi Chris,
      That is great advice! Thanks for sharing that. I am going to start including that into my troubleshooting tips. Thanks again!

    hopefully this is still active..

    I bought a replacement bulb for my HD65 because when I powered it on, the power light would blink green 50+ times then remain as a solid red light on the lamp indicator..

    After checking this forum, I ensured the replacement was a genuine OEM part (wasn’t cheap), that all the screws tight and the cover secure and clicking the trigger..
    when I power it up it behaves exactly as it did prior to replacing the bulb.. the indicator made me think it’s the bulb but I didn’t get any warning the bulb was dying and the picture looked amazing right up to when I couldnt boot it up..

    I’m hoping I’ve overlooked something silly.. any suggestions / tips are very appreciated

      Hi Chris,
      The simplest solution is to check that you have reset the lamp timer back to zero. That’s the final step for installing the new lamp and many people forget to do this. Without resetting the timer, the projector thinks the lamp is still old and will stay shut down to protect itself. To reset the lamp timer: Press the Menu button to open the On-Screen-Data (OSD) menu.
      Press the right/left arrow button to move to the Options menu.
      Press the right/left arrow button button to move down to Lamp Reset.
      Press Enter button to bring up the answer screen.
      Scroll over to select YES.
      Be sure the Lamp Reminder is set to on.
      Hope this helps. Let me know if it does. Thanks.
