Colour Hi I am having a problem with the red colour from the projector onto an interactive whiteboard. I have adjusted the colour setting but it still looks almost black instead of red. Regards Chris I have the Epson powerlite 7700p The whole left side of the produced image is a bluish color. to the right side of the image it looks fine. I know it's not the $500 lamp thank ***. What could it be, how much could it cost?

Ok this problem occurs mostly due to the loose connection in the VGA cable between the pc and the projector..
try changing the cable to give any other input and see it and then confirm it... that the color sensor of the projector is weak...

Panasonic interactive whiteboard won't project computer


If you'd like to email me at bruce.brassington@n-vest.co.uk I'll be able to help you in more detail. There's a fundamental error to the question here. That is the board in itself will not show the image - your boards is effectively a large flat mouse. A pointing device infact. The peice of equipment that "shows" your PC image is actually the projector. There could be several reasons why your projector isn't showing the image.
1 - is there either a VGA or HDMI cable connected from your laptop/PC to the projector (Sometimes via a wall plate).
2 If 1 is true and the projector is turned on does it show any sort of image? Now there are two thongs you can do from here. a) If you have a laptop check to see if your Video settings are set to clone across to a secondary monitor on most laptops you should hold down Function key and F8 this will toggle through three options Onboard screen remote screen and then both. there could be some lag between the two so hold down fucntio at the same time press F8 then wait a few seconds then go again.
Finally on you projector remote there may be an auto search buttion which will hunt for your PC image by checking each of the Projector inputs in turn. Generally speaking however you should select "Computer 1" or sometimes named as RGB 1

Hope that helps email me if your still having problems.

The picture suffers from colour fringing


either the color wheel has lost a segment or the colorwheel index needs to be adjusted in the hidden menu using the color ramps test screen.

The filters are starting to show their age. This is a normal occurance for projectors and is the result of heat. The filters and/or the mirrors might need to be changed.

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!

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.
