My machine is 3 months old with 970 hours on the bulb. The bulb turns off after 30 seconds, no LEDS. Machine keeps running. I've tried repowering, removing bulb, same problem. Thanks, Mike

    After storing my Optoma HD72 in its original packaging for the past year (after moving), I carefully set it up today. It starts up fine with an excellent picture, but then to my disappointment the bulb turns off after about 30 seconds, with no other indications. The “ON” light indicator remains solid green and neither the “Lamp” nor the “Temp” LED’s illuminate. The lamp only has a few hundred hours on it and again the “Lamp” LED does not come on. I tried taking the lamp out and carefully reinstalling it, but the results are still exactly the same.

    I have an optoma hd72 with 1190 hours on the bulb. On two previous occasions (and now this, the third), I have encountered a problem with the lamp turning off from 15 to 45 seconds after the startup screen has cycled thru and the initial DVD images begin to show.

    My lamp and temp lights are both off and I have "re-synched" the projector, re-set source. Neither of these maneuvers has corrected the problem.

    On the two previous occasions this happened. The projector went back to functioning normally after some 5 - 7 days?!!

    I am less optimistic this time (pun intentional).

    Projector goes dark after 15 to 30 seconds regardless of video type and source. Bulb has 1100 hrs.

    i had the same problem i send it in and they fix it but then the problem reoccurs about 3 to 6 months later....I hate this projector and my warranty has just run out. I have had it back to optoma 4 times...

    Same thing: bulb turned off after 30 seconds. Tried vacuuming, blowing canned air, removing and replacing same bulb, which all involved removing power, which I thought would reset factory settings. After seeing the suggestion for resetting from the menu, I tried that, turning lamp brightness off, and now it works. Turning brightness back on, makes the fan come on, and bulb go out. Thanks!!!

    Same here, shuts down after 30 secounds. Have blown it out. still shuts down. doesn't stay on long enough to get the menu to the point for resetting. sounds like a design problem from here.
    mine has been running about 18 months.

Just so everyone knows, This projector is notorious for the iris going bad. Which causes the projector to just shut off randomly. You will have to send it in for repair.

This is NOT a bulb problem unless your "lamp" LED is lit, which you say it is not. Many people have reported this problem with the Optoma 72. You can send it in for warranty service (it has a 2-year warranty) to get the lamp controller chip replaced, but the problem may recur. Optoma does not appear to have a permanent solution to this problem. My projector has broken exactly like yours TWICE in a year. I haven't even needed to replace the original bulb yet. :(

Same problem for me 16 months old, 1100hrs on bulb still under warranty.
Unit shut off after approx 90 seconds.
It continued to do this for 6 days straight.
On the 7th day I wiped the projector lens clean and have not had a problem for past 2 weeks.
I am a smoker so I am guessing the smoke build up on lens caused heat build up that triggered the shut down.
I will continue to wipe the lens before each use.

This is what the bulb does at the end of it's life. After replacing my bulb i have had no more problems. You can try to get by until your replacement bulb arrives by restoring to factory default settings. This will put you back into economy mode. This got me about a weeks time.

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.

New Bulb (30 hrs). Screen flickers after 10 minutes, color changes with green tint, then bulb shuts off.

Hi, I had a similar problem - the screen flicked through blue, green and red sometimes with a slight ticking noise. The problem seems to be that the colour-wheel is getting stuck - the first time this happened I sent it back to optoma who gave it a clean - it has happened again since thouegh and I just took the case off (you'll be able to see the colour wheel under a black plastic flap - remove the flap) I then used a cotton bud (q-tip) and turned the colour wheel whilst lightly pressing the cotton bud against the wheel - I also gave everything a blast with a can of air. My HD72i is ceiling mounted - optoma suggested putting the hoover pipe across the vents every now and then to keep the dust down. Essentially it's dust that is stopping the movement of the colour wheel.

Hope this helps.

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.

Can you tell me why the optoma HD72I lamp will turn off after just a few minutes of running, the lamp is still fine

I have the same problem. I got a new bulb and it worked for about 1000 hours, then the new bulb started having the same problem. So, I was about to buy another bulb, and I figured why not try the original bulb. IT WORKED! For a couple weeks... Then it started doing it again. Obviously there was nothing wrong with the original bulb, and there is nothing wrong with the new bulb, but I have 2 bulbs that do it now. So, is there any way to just tell the projector run the bulb till it actually dies and not turn it off because it thinks it is about to die.
