The DMD boards were used in earlier DLP sets but I do not think this set --model is a LCD set uses that but has a main board instead---you may want to do some research on possible boards for this model which should be LN37A550P3FXZA and not IN.

SOURCE: can a tv be fixed if it needs a dmd board? My

If the Menu is clean it is not the DMD . I would suspect that the problem is related to the analog or digital video processing circuits. What is the input source you are using? Did you try a differnet input source and see if the problem persists? For example if you are using HDMI use RCA (Yellow, white, red cable is required) to see if the problem persists on analog inputs as well. If you are using analog inputs such as RF or RCA try a digital input such as HDMI and see if it persists on digital inputs as well. this will help us isolate the problem so that I can link you to the correct replacement part.

I think you have a colorwheel with bearings that are noisy and theres no telling how long it will last . Could be days or years, just noisy. But a colorwheel will not cause a picture to freeze. Sounds like two problems- a questionable colorwheel and a failing dmd board .
Most likely your problem is on the DMD Assy Board P/N BP96-00249A . More presicely there is a few bad electronic components on that board that are bad. That board can be repaired by replacing the bad components (and the other few compoonents that are probly going bad and will soon cause your tv to lockup and lose remote and button functions when it fails so you will need to unplug it to get it on again).
Or the DMD board can be replaced .But it is not a cheap board.
For removal and Installation of the DMD board I would reccomend a tv service person because it is in the heart of the television and there are some adjustements to be made when the new board is installed.
To get the new board you could probably find it by just gooogling the part number.
Component level repair would require some experience in desoldering and soldering SMT,SMD , and or surface mount components.The actual components are about $15.00 total so just repairing your board should cost about $125.00 by a qualified servicer (if you were to remove and install it yourself). This DMD board is used in many models and can has few common problems.
HLM437W HLM4365W HLM5065W HLM507W HLM617W HLN437W HLN4365W HLN467W HLN507W HLN50665W HLN567W HLN617W ( L2 and L5 chassis )
SYMPTOMS:
-Intermittant picture freezing with a negative looking B/W frozen picture.
-Intermittant loss of pic with/without shutdown
-abnormal color wheel noise if attempted to start right after shutdown.
-lockup of tv control functions . Remote and front keypad do nothing , TV must be unplugged to reset .
-horizantal tearing, distortion , flippnig , solarization , red picture, leading to blank screen and lockup.(tv menu would be affected by all picture defects if caused by DMD board).
Hope this helps someone..

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!

Samsung DLP model#HLP4663w.green hue on the screen,what is the solution to my problem.


Hi,It sounds like it could be the color wheel or DMD.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 get color distortion ,black and white picture and sometimes you will hear humming noises.
