Question about NEC MultiSync MT1050 Multimedia Projector

Open Question

NEC MultiSync MT1040, Color Alignment

There is a dark yellow/light green stripe on the right side of my projection, and very noticable displacement of all yellowish colors.
I understand realigning the color "guns" is tricky and complex, but
returning it to the manufacturer is not an option. I need step by step
instructions on how to either use the menu to align my colors, or
do it manually.

Thank You.

SOURCE: MT830 Color Convergence (Blue Left - Yellow Right)

take a look here: http://www.extremetech.com/article2/0,1697,1049289,00.asp "... The others, however, have lost portions or all of their blue channels. TI's theory is that the shorter wavelength and higher energy of the blue light apparently causes the organic polarizing material in the LCD to get lightburn much faster. TI showed us a damaged LCD panel that controlled blue light transmission, and there was a large spot in the center that was apparently burned out..."

Hi

pls check the board before the color wheel, as it is noticed that this problem comes with the main PCB Board.

I can assist you with that if you want. It is very tedious, but can be done. You need a cross hatch pattern generator or something with vertical and horizontal lines to lineup the LCD Panels again. Tricky little procedure if your not familiar with it. Let me know if i can assist you and hopefully save you agravation at the same time. Thanks Jay

A trapezoid can be corrected using the "keystone" feature. This is used when your projector is located above or below some angle other than 90° to the centre of the screen.

As for the second tone, that may correct with the keystone.

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.

Look for bad caps with bulging top in the power supply first, post back what you see inside so we can guide you further, see example of failed monitors due to bad caps (after about 2 years): http://s807.photobucket.com/home/budm/allalbums
