    The projector works fine initially, then as it's working for a few minutes, the picture starts to display a slight purple cast, and as time goes on it gets more and more pronounced, until all skin-tones are vivid violet. What's up?

I had a similar issue with my EP739, the problem would start after about 3 or 4 minutes and then get gradually worse and worse..
The most strange thing I noticed was that white looked fine. And if you opened the configuration menu in the projector it appeared that blue was labeled green and green blue..
Some sites suggested cleaning the machine of dust, which I tried using a can of compressed air... This did not fix the problem at first.. but when I had it apart I studied the colour wheel for a little while and wondered if some how the machine was synching to it incorrectly somehow.. So I blew out the colour wheel location sensor (It's kind of obvious being the only component mechanically connected to the color wheel. Much to my delight, this fixed the problem...

So my solution to the flickering / colour fading / colour swapping issue with DLP projectors was to clean out the dust from the colour wheel location sensor..

In fact, if I did it again, I would ONLY clean the sensor, and leave the rest of the dust alone. Blowing dust around has the potential to cause other issues, especially if it winds up inside the optics system.

Hi there

Have you tried using a different cable ?

If you have and the problem still persists , this could be faulty Mainboard that will either need repair or replacement.

Please try a different cable first and let me know what the outcome was.

Thanks for using Fixya and Good Luck !

Optoma h31 stopped suddenly. I replaced the bulb, but the power button isnt flashing green, and I cant turn the unit on.


The little metal plate on the projector next to the bulb housing is not fully depressed (pressed down). The plastic cover is suppose to have a plastic piece protruding from it which is to depressed the metal plate when the cover is placed back on. If the metal piece is not pressed down, the projector will not light.

Optoma h31 was unable to power up


It can have two problems. One is that the lamp has gone out and needs replaced. Refer to your troubleshooting section in your manual. Also can be bad capacitors in the power supply circuitry or Voltage Reg. IC. Either should be left to competent repair individual.

Optoma H31 - Turns itself off !


sounds like the projector lamp to me. the rated hours are always up to the published hours and never "this is what you will achieve." I would suggest getting a lamp as you will need one shortly by the sounds of it. In many cases the projector does this as it is programmed to protect itself from the lamp shattering inside the projector. Let me know if you would like a quotation for a lamp as we ship internationally. Regards Kevin Andreassend. http://www.iceav.co.nz iceavtech@gmail.com +64-9-4142348

Everything/everyone is purple on a H31 optoma pic


Hi, genelewis! Well good news for me, and also hope for you; I got my projector to work correctly again, at least it has not had the problem for a couple of days of probably 10 to 12 hrs use of movie watching, before it could not go an 1hr without the purple issue.

I was looking at other sites and this one with other projectors and it sounded like just dust in the projector... after just about 3 years now without a cleaning I think it needed some maintenance, so I carefully took the bulb out (1 black screw on the bottom) and opened the projector (7 metal screws in total), and after some investigating on any wiring that may interfere (only on the inside back of the white top cover, were the inputs are: a wire band and some small metal sheets that kind of grab the top) I pop the top, not that hard.

After that I just carefully used a can of compressed air to blow away from the projector any dust I could reach and in some of the crevices I saw, being careful were the mirror is (were the bulb was); I was tempted to get the glass that covers it off to get some dust off but the screws are small and kind of hard to get out, so I left that alone. Cleaned any dust accumulated on the air intakes with a clean soft cloth and closed it up again. I did not want to touch anything else unless this did not work, but this did the trick! I'm happy with my H31 once more.

I hope this helps you, good luck. Let me know if you need some more details

Can I buy and replace a clourwheel unit for my optoma H31 myself??


There is no "color wheel" in these units. These projectors use a series of LCD panels and filters to create the picture as far as I know. That optical unit will not be cheap. WHat is the rpoblem with the unit that leads you to believe this needs to be replaced?

Color


Hi, If you have tried other video sources & still get the same results. It sounds like the motor that turns the color wheel is going bad, These motor's run from 5,000 to 10,000 rpm depending on model & are usually the first point of failure in a color wheel based DLP projector, If you don't count the lamp.
Overtime it may begin to make a squealing noise. Usually you can find replacement motors on the internet by searching the part number printed on the motor google is great for searching part numbers.
