The part to clean is the sensor that wraps around the colour wheel or some thing on it's axle.
This sensor identifies when the colour wheel has made a revolution and syncs the video output to the right segment in the colour wheel so only the red image is displayed when the colourwheel is filtering red, etc...
If the sensor gets dirty it will not be able to tell exactly where the colourwheel is, and in my case started to report a segment off.
Consider this before you take your machine apart.. I live in New York City, and this area is rather dusty.. I've had my projector for 2 years running pretty constantly, so it was pretty dusty. I mention this because there are other possible causes to this problem. It could be an electronic issue.
There were three things that convinced me it was a colour wheel issue : 1) The problem appeared slowly over the period of about 2 weeks.. First it started flickering, and then all of a sudden it would switch back and forth.. 2) The color white was fine. In fact, the image was fine, just some colors were switched. I could even fix the image by adjusting the hue in my video.. 3) My machine was full of dust..

I don't know about the HP projectors, but this is the best I can do to describe how to locate the colour wheel...
If you take the bulb out of your projector, you'll probably see part of it.. The first thing wherever the bulb shines into is probably the colorwheel (or a protective cover). In my machine there is no way to access it from the bulb housing, so I had to take the entire case apart.
From there you can clearly see how the bulb shines through the colourwheel, and then then light enters a closed chamber (sealed, I assume, from dust).
If you are not able to locate the colorwheel after this, maybe take some pictures with the case apart and send them to me.. I'll look for a manual online in the meantime..
Also, I'd be happy to talk to you over skype to get more detail.

After projector is on for a lilttle while the pic flash an changes to blues an greens...just changed the bulb an it has did it again..


hi,
first of all check the tint setting on your projectors picture menu.
if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for counting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
i have added a video how to clean the color wheel . not the same projector.

ok

My HD 65 keeps flashing green.. I turned the high altitude on and it stopped.. But it's now starting again.. There is only 480 hrs used. What to do??????


From what I've read, flashing colors could mean dust on the color wheel. Try removing the lamp and blowing air on the color wheel. Also if using the red,blue, green cables check to make sure the red is in tight.

Epson 76C projector that the picture has no red color to it. I have tried the adjustments as described in the manual but no success. The blue and green is great but no red? Thank you.


Youve probably got something gone wrong with your dlp chip with the million mirrors on it, see when the mirror tilts away from the light you get a black shade- tilted toward light lighter shade now throw the color wheel in which gives you color youve got green and blue so the color wheel is fine. Now how to replace chip? Dont. Look for a digital board or video board replace that and that should take care of ya. Good luck hope this helped ya-

Green screen projection


This is the exact same issue as I described for an Epson user. So I'll repeat it here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the green color has gone out. The image is made up of red, green and blue images layered upon the screen. If the green panel has gone out then there is nothing filtering out the green light in the image. This causes a nice green hue to the whole screen.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Images has a blue color across the center


Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Colour problems with projector


In short If the reds show as red, The greens show as green & Blue shows as blue. I would say thats as good as it can project. It's hard to judge color without seeing it for ones self but usually DLP projectors that use a colorwheel do not have perfect color.
