Question about Optoma H30 Multimedia Projector

1 Answer

Picture is green with some purple shades

I have an optoma h78DC3, have just replaced the blub and cleaned the filter. I read you can shoot some air thru it to blow it out some but so far still get the same results. I have it ceiling mounted and inverted. I live in Roswell Georgia. Is there a repair store nearby that can fix this. Are there other things i can try to do to fix the color problem.....it has worked great up to now. I have seen some info regarding a color wheel but i do not know what that is ........the manuels dont show any maintenace or real instruciton other than some user adjustments and installation type stuff

Help I want to watch on the big screen

    Please  inform  the  method  of  resetting  the  LCD  projector  to normal condition

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.

Does the Optoma HD20 DLP projector have a air filter? If it does, where is it located?


Hello

The Optoma HD20P doesn't have an air filter.
If you remove the covers you will find 2 cooling fans that get a build up of dust on the leading edges of the fan blades.
These can easily be cleaned with a small paint brush and a drinking straw to blow out the excess dust.
If you are having overheating problems, please view my post on replacing the heat sink compound on the image processor.

Cheers

yes, any projector with a air filter.

if your projector often make overtemperature protection, you have to inspect the air filter,whether it is still clean, otherwise, you need to replace it.

Optoma EP7155 gets very hot and shuts down.


Hi

Possible filter problem since its overheating. clean up filters and make sure that you use projector in an open area so air can cool it off while running.

Hope this helps

Hitachi CP-x430 "Check air flow"


I have run in to this time and time again. This is why I like to keep things clean. take the bulb out and blow the unit out with air and make sure you wipe off what you can with Q-tips The blub allows air to flow thew the filament so what ever dust that might touch the fillament while its burning will burn at a higher temp. this will send and indication to the unit to send a message that says replace bulb soon and If there is not enough air flow it will say CHeck air flow take the fliter out and clean it with water dont replace it. IF you do just buy a carbon pad and cover the hole(not recomended foir those who are not handy) but keep things clean and it will save you $ in the long run. How many bulbs do you want to buy?

I have the optoma h31 projector and the color turned purple. We assumed it was the bulb and put a new one in. The color is now still not right and the picture sorta bounces


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.
