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 screen. 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!
the problem here is the crt cicuit unplug from the wall take off the back its the cicuit board thats pushed on to the tv screen pull it off. you will see R G B its the B one thats faulty it looks like a transistor. call an engeneer and he will put a new one in for you i hope this helps you???????
what video device do you plug in to your TV screen, DVD player/VCR or game console?
If you still have the owners manual of your TV screen, look for instruction regarding Color system or video system. this menu will allow you to change color sytem from PAL to NTSC or AUTO system. most likely the reason why you have a black and white color from vidoe input is because of system color compatibilty from your input device to your screen.
Or if your using a dvd player, you can also try accessing the "setup" button and look for video setting. from the video setting there will be selection to choose from: PAL , NTSC, AUTO . always select "auto" so that the color system of your DVD player can change from PAL to NTSC deffending on your TV screen system setup.
Since you're using a composite cable (yellow RCA) that carries both luma (brightness) and chroma (color) information, it's not the cable that is the problem.
That means it's either the DVD player itself, or the TV. If you have another video device (VCR, etc) that you can connect to the TV, try that. If the other device also goes from color to black and white, then it's your TV. Otherwise the problem is your DVD player.
Since your TV only has mono audio (white RCA, but no red) I would recommend getting a new TV if the TV is to blame.
go into menu turn color off see if you have a black and white picture if not adjust red,green, and blue screen drive on controls in back of tv you have red, green, blue it will have focus /screen controls cover each tube do one at a time blue focus and screen drive adjust to clear blue picture do all 3 tubes, then adjust them to where you have a black&white picture once this is done turn color controll back on.Thank You for using FixYa and Have a Nice Day.
There some thing that you had done to get black and white on your tv with the dvd ,check your connections.if the connections are properly connected then the tv could be having a problem in the video input, have a tech look at it.
