I don't know if this will work but..... I have an Optoma h27 and we were having problems with the color and ours is mounted on the ceiling in inverted also; and after two years we started having color problems, come to find out that on the menu there is a option for high altitude and that had been turned to the "off" position (probably by our kids resetting all the options and not turning this one back on)..... after taking it to a tech that cleaned it for $97.00 and said there was no problems he could find, we played around with the remote/menu and came across this high altitude option and when we saw it was on the "off" position, we put it to the "on" position and another fan inside the projector came on and that helps to keep the inside of the projector cool at all time and helps from the color becoming weird..... Try this on yours and hopefully that will solve your problem.

What does it mean when all three lights, standby, temp and lamp, remain solid on Optoma HD72?

I suggest you go to eserviceinfo and search for the manual on this unit, sometimes this indicates a filter door open or bulb carrier door not closed. But to be honest without seeing the manual ?, however you didn't say if the unit was working despite the lights or not. Check the doors to all compartments and see if they are closed properly, other than this advice I suggest you seek an engineer to check it out

It sounds like you bulb is ready to die. First clue is picture quality. That happen to me and a new bulb remedy the problem. Bulbs are expensive though.

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.

Colors flickering

Easiest and cheapest to just fix it yourself! The problem is with dust/debris accumulation on the color wheel. Very simple to fix. Remove the lamp and you can see the color wheel. You may be able to clean it from that hole using compressed air. If not, you will have to take the outer casing off. A film will build up on the color wheel in certain environments, smoking, dusty areas, placement next to ceiling fans. To remove the film build up, use a q-tip with denatured alcohol. start from the inner part of the color wheel and work the q-tip upward towards the outer part of the wheel. you may have to remove the cover plate to the color wheel to clean the other side( side facing the lens). Not a big deal and will bring your projector back to its original vivid colors. As for LCD projectors, they are only good for one lamp. You will never get the full use out of a second lamp as the lcd panels degrade fairly quickly. Usually the blue lcd panel is the first to go. A DLP projector can last you for years and many replacement bulbs. Replacing a color wheel is fairly easy. Replacing lcd panels, not going to happen as they have to be calibrated and are very expensive. P.S. If you are a smoker and you do it in the same area as your projector, you will get a tar build-up inside the projector. The tar will accumulate on EVERYTHING and eventually lead to overheating as well as color wheel issues. The reason I mention this is I just repaired a Optoma EP721 (very similar to the HD65) that had this issue.

Optoma hd72 lamp driver problem

I have had this manufacturer defective HD72 unit for 4 years now. So let me break down this issue as I have experienced it for 3 years.

1. The issue is with the lamp driver(bulb power supply), replacing it will fix the issue, but the new lamp driver you install is also defective and will eventually go out.
2. Replacing the bulb will place less stress on the lamp driver and will temporarily fix the issue as well (this is what I did first because the warranty department, when I was under warranty told me this was the issue but the bulb was not under warranty at the time).
3. I have my unit mounted on the ceiling, upside down. For some reason, turning it right side up extended the life of the lamp driver by 8 months. I have no idea why gravity makes a difference, but it does, try it, it is the quickest/cheapest/easiest thing to try. I read on a web site that it would work, and I thought it was stupid, but it actually did work.

The real problem is that this is a manufacturer defective projector which they do not have non-defective parts to sell you even though they have known about this issue for at least 4 years now, they have moved on and want you to buy a new unit that is not defective instead of fixing this one.

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.

Optoma hd72 bulb turning off

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. :(
