Hello there,If your movie projector light bulb has stopped working, there are some simple steps to take to get your movies playing again. The hardest part may be finding the correct replacement bulb. There are so many different models with their own specific bulb. Here are some steps to follow to replace your burned out light bulb.

  • Locate the bulb in the movie projector. You may need to use a screwdriver to open the bulb compartment. Check your owner's manual for proper procedures.
  • Step 2.Remove the movie projector light bulb or lamp. The bulb must be cool before you take it out. Use a tissue or cloth to remove the bulb because the glass bulb is very fragile. Do not throw away your bulb yet, you may need it to help find a replacement.
  • Step 3.Find replacement bulb. The Better Lamps website offers a wide variety of light bulb models. From their homepage select the brand of movie projector you have and using the model number from your old bulb, buy a replacement.
  • Step 4Replace the movie projector lamp or light bulb. Do not touch the bulb with your skin. This can transfer oils from you onto the bulb resulting in a hot spot which can make the bulb burst. Use a tissue or cloth to handle the new bulb to screw it back into place and then replace the cover.

    SOURCE: lamp flashing, hd72 projector

    In most projector menus there will be an option to reset the lamp timer, it's usually under the "settings" area of the menu. Try resetting the lamp timer and the light should stop flashing.

    Hello, I am having a problem with my hd72/hd6800. My projector is on its original bulb and has about 500 hours over 5 years. Today i was able to turn it on, but the lamp wont light up. I hear the fan start...


    Despite the relatively few hours on the lamp, the fact is it's over 5 years old. It is not uncommon for a lamp to age and be too weak to fire. Replace the lamp, you should be fine.

    My Optoma HD72 projector operates for about 1 minute and then shuts off. I kept my old bulb around "just in case", I've replaced the bulb with the old one and have the same problem.


    The problem is not over-heating. The Optoma HD72 has a known problem that Optoma won't advertise. The lamp driver is faulty. They simply have to replace the lamp driver. I purchased a spare lamp with my original purchase. I had the exact same experience as you at around 1200 hours on the lamp in ECO mode. I used the spare lamp. Same thing happened at about 1200 hours. I had a friend at Optoma. he confided to me the problem. I sent it in and they replaced the lamp driver at no charge. I got another 800 hours out of the first lamp and am now using my second lamp and have about 600 hours on it. The pic quality is so good with this projector (used Digital Video Essentials to calibrate) that I'll just order a bare lamp or two and use the existing lamp housings when I need a new bulb.

    Optoma HD72 flashes red and green. I changed the lamp but the problem wasn't resolved. Any input would be greatly appreciated.! Greg


    I had the same problem with flashing colors after playing for awhile. The following helped:
    1. turn off bright mode from menu.
    2. keeping the back side of the projector flat. I had it raised up about 3" on the backside before, not sure why but it worked fine when flat.
    Hope these help you also.

    The optoma hd72 projector lamp goes out after 30 seconds.. the big game is this weekend... what can I do?


    I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

    I have taken apart my optoma hd72 to replace the lamp driver board. I have loosened the screws on the main board to remove it so I can get to the lamp driver board underneath but its seems to still be...


    The board under the mainboard plugs into the top board like a cartridge. You have to disconnect all the cables from the mainboard then pull up on board to detact it from bottom board then you should see lamp driver in the back. Make sure hands are clean from static. Good luck.

    HD72I WORKS FOR 30SECONDS AND THEN SWITCHES OFF


    I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.
