GREY SPOTS ON BACK OF SCREEN NOTICEABLE WITH WHITE


Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Everything that is supposed to be black is showing


Hi,It sounds like a problem with the color wheel or DMD board. The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will hear ,humming,buzzing,high pitch noises ,you might also experiment color distortion ,black and white picture.

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

Black and White


on a low signal input to the set the first thing you loose is the color, then it goes snowy and then just snowwhite in a snow storm or all blue with no sound.

check your cables for no shorts and loose connections,
sometimes the color killer control inside the set in the color circuit has to be tweaked alittle.
