where i got Optoma HD70 DLP Projector spears

I could obtain this Manual from Optoma for you as I am in a position to obtain these sort of things.

Kindly refrain from locking a rating if the problem isn't solved first time round.

Hi guys

Your best bet on getting your hands on a Service Manual would be to contact Optoma themself.

As for changing the colour wheel , it is pretty straight forward if you were able to open up the unit and get to it.

The colourwheel is mounted with three tiny scrws to a bracket in which it sits. And the bracket in it's turn is fastenend to the body of the Projector with two tiny screws.

First unscrew the bracket from the casing of the Projector and then take off the three screws that holds the Colour wheel to the bracket. Replace and do the whole proses again - but obviously just the other way round.

This is really easy to do yourself.

Give me a shout if you need any further assistance.

Thanks for using Fixya and good luck.

Hi Brad

You'll have to go into the service menu and check if all the colours are showing the same percentage.

We normally set all of them on 50%

Hi danny,

I also replaced the color wheel in my EP739 after the old one disintegrated suddenly. Colours were then all over the place. Actually, it looked like each colour channel was displaying all the colours of the rainbow!

Here is the procedure I used to solve the problem - maybe not as elegant as Marrie's solution, but it will not cause any damage, will most likely solve the problem, and you will be able to get everything back to the way it was if it doesn't work:

1. Have the projector running and displaying a stationary picture. The right sort of picture to use is one that has a full range of brightness values from near-black to peak white. I used my lap-top as the source. Also, this way you can compare the projector's picture with the picture on the lap-top.
2. Press the power button once. "Power off the lamp" dialogue box appears. Hold down the left arrow button until the service menu appears (takes about 8 seconds).
3. Using the up/down arrow buttons, scroll down to "Color Setting" and press "enter".
4. Scroll up to "Color Wheel Index". Make a note of the existing setting for later reference. You can change the Index setting over a range of 100 to 550 by holding down the left/right arrow buttons. As the setting changes, the colour rendition will slowly change, and at some point the colours will come right. Note that the changes are quite slow. Find the lower and higher settings where colour aberrations just start to appear, and set the Index mid-way between.
   
5. If this doesn't fix the problem, return the Index setting to original. My original setting was 354 and the new setting was 461.
   

I do not advise touching any other settings in the service menu unless you have access to a service manual and know what you are doing.

Good luck!
