Re: projectors display

The lcds areout of alignment. you'll need to send it in to a service center to have them do it. you can try yourself, but you may need special tools.

Red color seperating

If you mean the red light is displaying offset from the blue and green then the red LCD panel inside the projector needs to be physically adjusted. If you take the projector apart you'll notice that the light source is split into red, green and blue light by passing through an optical splitter. Each color then passes through it's own LCD panel. Next, each color is joined back together by another light splitter to be projected to your screen. The red LCD panel is misaligned.

I see no red and green colors on screen projected by pjtx 100, the rest of the colors are visible.

If you are using a component video cable (Red, Green, Blue) you may simply be missing the Red cable. It may not be fully plugged in.
You can verify that this is the case by: 1. Unplugging all video cables 2. Plug in the green cable, you should see a black and white image. 3. Plug in the blue cable, you should see some colours coming through. 4. Plug in the red cable, you should see all colours properly.
If not, unplug the blue and red cables and plug the blue cable into the red port. The colours will look incorrect, skin tones will be blue. If the colour comes through the problem is the cable. If the colour does not come through, the problem may be the projector.

The left side of the screen is blueish?

The blue or yellow haze problem in this projector is because of two factors. 1) Dust buildup inside the optics and 2) Fading colour filters used in the internal optical process.

Inside the projector the white light from the lamp is split into three distinct colours of red, green and blue. Each colour illuminates their own monochrome LCD. Those LCDs are mounted on a prism that combines the separate images and displays the result you see via the lens.

The optical process to split the light up inside the projector is fairly complex and involves many light filters and mirrors to direct the light to the appropriate lcds. Those filters and lenses accumulate dust and also fade over time due to heat and other environmental factors.

I know that sharp sells replacement filters at $100 a piece. I do not know if Hitachi sells replacements.

To remove the dust and change filters you have to take apart the projector in a fairly complex way. I do not suggest that the average user do this. Good luck!

In the menu selection I don't have access to sharpness, or color adjustment. The picture image is violet. How do I make adjustments in color?

Sounds like the pins on the computer cable are bent...there are three pins that carry Red Green Blue parts of the picture . if one is missing, bent etc you will loose that colour.
It could be more serious also, UV filters in projector are worn out, these are not user replaceable items, or if DLP many be part of the colour sector is missing.
If you ever need a lamp we are able to supply replacement lamp delivered next time you need one, as we ship internationally and also the same with our revolutionary ICE Digital Daytime projection screens. Regards Kevin Andreassend ICE AV Technology Ltd New Zealand +64-9-414 2348

NEC LT35 color problem

If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

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.
