SOURCE: Infocus LP70 - It's all Green

A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).

Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

Hi there.

This is definetly the light tunnel issue. After searching and a million phonecalls, I tracked down a place that you can buy the light tunel for $41 on their own and simply put that in, making the projector good as new.
I Have the phone number of the place and also the link to the forum giving you fully pictured diagrams of how to change the light tunnel, and also I have a service manual if anyone would like it to be sent to them.

Cheers
Russ

SOURCE: Right side of the image is very dim, left side is near normal

the light tunnel is collapsing and needs replacing. it is very difficult to do on your own with out the proper setup. you can send it in for repair, but it'll take them about 1 1/2 hours. the part itself is not expensive. try av solutions in ny. they're pretty good. www.avsolutionsny.com

Why do i have a green screen after i turn the screen adjustment screw?


since every display color monitors are only work with 3 primary color which are red, blue and yellow. You could also search it that by mixing these colors, you could get any color your want. Thats how color monitors work. Now in case of green color, it creates by mixing blue and yellow. When you are turning the screen adjustment screw, the red color plug will become lose, makes it appear green.
I hope your got the reason.

If you get only black smudge even when you're printing in color your problem is most likely the black cartridge. If it smudge in colors look at your transfer belt, open the front door, the big belt that hangs on the door.

Toshiba Satellite L35 screen color turned to pink.


If you have a LCD-screen, not an old-style CRT-screen, it is the data-cable, and its connections, that are not transmitting one of the 3 "primary" colours, e.g., mix red & blue & green to get white,
but mix only two of those colours, and you could get pink,
because the mixing is an "additive" process.

If you mix NONE of the 3 primary colours, you should get BLACK.
If you see GREEN, you're seeing ONE of the primary colours.

My screen turns green and then turns off


you need to adjust the screen voltage. behind the front grille and inside cover. a small black box 6 adjusters protruding from it. only adjust the the color counterclockwise that matches the problem in this case it's the green so look for the knob with "G" marked by it. there are 2 with "g" marked by them the row across the top of the box are for focus don't adjust. back the knob off untill the raster is blank with your input set to an inactive input, the picture should be blank and black.
when it is you have the adjuster close to where it should be, now change the input to an active signal and turn the color off so that you wil have black and white picture. adjust that knob untill you do have a truely black and white picture not too green or red or blue. go back to inactive video input and check that there are no lines of any color on the screen. repeat if needed. always adjust these knobs slowly the set will be watching you ! if your autofocus won't work now you have the adjustment set too low. check this function before putting back together again. these adjustments can be real touchy so be patient

Color problem


There are three Cathod Ray guns responsible for the millions of colors.All colors are produced by mixing the three basic colors namely Red Green and Blue (RGB) at suitable proportion. If any one of the three guns fail firing then we get improper colors. This can be rectified by
(1) hitting the monitor at the back by keeping it on a pillow the screen facing down - it will reolve the problem if the failure is due to the loosening of the Head due to repeated thermal expansion and contaction.
(2) check the signal cable for loose connection, twisting etc on both ends - at the back of the CPU and Monitor (it is fixed)
TRY YOUR LUCK
