    I just dropped it off at a repair shop. Im pretty sure i replaced the door correctly since i did it a couple of times. Im not even sure it was a bulb problem - i got no bulb warning. The picture would flicker and turn greenish with a mosaic look to it. Ill post the results from the shop when I get it.

    My Optoma EP739 projector worked great for 2 years on one bulb. I replaced the bulb after 3000 hours of use. The 2nd bulb worked for 2 months then the picture slowly started to flicker and turn greenish. So I put a 3rd bulb in and it worked for 5 minutes and started to flicker and turn greenish again. The picture is fine for the first 5 minutes then flickers and turns green everytime. I don't think its a bulb problem. Watching shows in an all green picture sucks. So I hope someone can figure this out.

    I also put the first bulb back in cause it never had that problem, but it does now.

These units have many safety interlocks. First make sure that all of the doors that you opened are replaced correctly. If not, the interlocks will prevent any power from getting to the unit. Update this with what you find.

Blotchy colors on optoma hd80


i had, have the same problem i also replaced the bulb then shortly after the power went out no standby light or anything. From what i've read so far it seems like a power supply issue so i ordered two power supplys from optoma 1 for lamp 1 for the unit waiting on delivery from CA they were $ 99 each if this work i'll be one happy camper. Three years no problems it's a great machine with incredible picture using 106" screen

its not the color wheel. Its the sensor that counts the black tape on the color wheel. The sensor has dust on it. It can't count how many times the wheel is going around because the dust is blocking it. the sensor is located by the wheel. if you have any questions you can callme 610-842-7442 ask for dan.

Color wheel failed. Can I fix it myself??


If you contact Optoma and they have the part available then, yes you can fix it yourself. You have to be good at taking things apart and remembering how they go back together. Changing the color wheel assembly is not that hard.

The lamp cover has a disconnect that wont allow the unit to power on while the cover is off.

Try taking the lamp cover off and bending the little piece of metal you find underneith.

It worked for me.

Installed new color wheel not working correctly


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!
