How to clean optoma h27

Hello, My h27 projector is showing dark purple colors. I believe it is time to clean the projector. I've had it cleaned in the past before by a projector technician but this cost 125 dollars for only a cleaning :( Does anyone know of a forum that gives detailed instructions how to clean one of these projectors? I've opened it up nearly half way before (removed the exterior casing from the guts of the projector) but to my dismay could not figure out how to disconnect the blue ribbon wire. I ended up spraying canned pure air into what I could, it worked well for about 6 monthes after but now has started to appear again... Could anyone help me (and hopefully other H27 owners) learn how to clean this projector? Thanks in advance!

ALSO CHECK YOUR FAN. IF THE FAN OR A HEAT SINK IS NOT WORKING PROPERLY (I.E. THE FAN MAY JUST NEED TO BE CLEANED OR REPLACED, THERE SHOULD BE A SMALL HEAT SINK. IF CLOUDED W/DUST, IT WILL KEEP THE OPERATION SHORT). ALSO CHECK IF YOU HAVE SET ANY TEMPERATURE SHUTDOWN PARAMETERS. IF YOUR LAMP HEATS UP FOR SO LONG AND REACHES A TEMPERATURE THAT WILL AFFECT THE CIRCUITS, THIS OF COURSE WILL SHUT DOWN YOUR UNIT UNEXPECTEDLY. HOPE THIS HELPS...JGUAM

Well we found the problem……. (but no thanks to the technician who charged us $97.00 to clean it and say there was no problem….) In frustration and playing around with the menu on the projector, we saw that there is an option for high altitude and when we click on that and seen that it was on the “off” position we selected for it to be “on” and guess what? Another fan came on and apparently that fan run constantly to keep it cool inside the projector….. must have something to do with mounting the projector on the ceiling…now the color is back to perfect again...thank god.....we have our theatre/sports room back.....
(I can only guess that my kids hit the reset button on the menu to reset all setting and it turned the high altitude off…) Hope this helps anyone else having similar problems…..

SOURCE: Help! Our Optoma DLP

There is a lense behind the main focus lense that's causing this. Flakes of the colored tint are coming off causing white light to shine through. If you look at your projection, you can see black spots as well, these being the flakes that have re-located themselves. I dug into mine deep enough to diagnose this, to actually replace the little lense would be a little tricky. The unit has to be mostly disassembled. Also I haven't been able to locate a vendor who sells the part. Optoma wants you to send it in so they can do the repair, and won't part w/ these component level parts.

I just bought a top-end MacBook Air 13.3" 4 GB/256 GB for presentations. I also have a Dell M410HD projector, also quite new (a few months old), which works great with the two PCs (one new, one old)...


They (Apple) might be right. It could be that the projector is damaged, like the bulb, or it could be incompatible with your computer, but I don't think that is the case. Try taking the projector to a computer repair place.

I'm noticed white spots on the screen and from the past two days its getting worse. kindly suggest me and give me step to step cleaning process if i can do it myself.


check if the white spots are well defined square pixels on the screen. If they are then you may have pixel failure.

  • After turning on the projector, press "+" and "-" buttons on the control panel simultaneously and release the buttons when screen goes blank.
  • Press "+" and "-" buttons again to exit the diagnostic mode.
  • While in Self-diagnostic mode, the screen will run a seven-color-cycle test as following: "Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow." Ensure that the colors of the test pattern are correct.

  • If you believe it's dirt then disconnect from the power and undo the screws underneath the unit. lift the cover over the front of the machine and carefully remove the pcb to get at the optics. don't touch and glass bits with your bare fingers. clean the optics bits as necessary with a camera dust blower bellows. best of luck.

    can you take some pictures of the optics and send them to me ? this could be a circuit fault or a defective run from the manufacture, you will half to identifie whether it is optic or circuit related, try and place a piece of color filter opaque paper between the optics and try to notice the changes on the screen this may give you an indication which element may be faulted, or if it is electronic

    The images displayed are purple. I sometimes solved the problem by adjusting the focus. Now it remains purple all othe time.


    Hello...The problem you're describing is related to the green lcd and most likely the main board(green channel). If the focusing removes the purple(you have *that* much dust in the unit?) then it *is* dust. You should be able to focus on the dust particles twice--dust on the front of the lcd and dust stuck to the back of it. I'm gonna give you the color table so you know what to look for and what you're seeing. Red LCD=cyan(baby blue) onscreen; Green LCD=violet(purple) onscreen; Blue LCD=yellow onscreen
    If you have a lot of dust(and the green lcd usually is the main culprit by the design of the lcd panels around a glass "cube" internally) you might try blowing some air into the unit when it's cool. However, the unit probably needs a good cleaning--remember to clean the dust filter! To properly clean the unit, a trained tech will have to perform the job. The lcd panels are DELICATE and precisely positioned for displaying a sharp image.

    Dark area on right side of screen, just showed


    I am Brasilian and i don't speak english very well, so sory. A friend had the same problem,and other friends too.

    The mirrors and the Color Wheel of the Infocus sp4805 are atached with fragility by glue that with the high temperature and humidity deteriorates. The detachment of the color wheel or the mirrors drivers of light produce dark spots. It is easy to solve. Just paste again, but should be done by specialized professional.

    Picture is green with some purple shades


    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.
