Samsung led TV un60es8000 dark blotchy area on the upper right of screen. Most noticeable on greys,blues and blacks. The picture attached is the color most responsive to this issue (dark grey). Lighter...


This is caused by one of two things; a bad LED grouping (most common cause) either because the LEDs are bad or the power distributor fuse is blown and the group isn't getting power from the power supply unit. Or two: bad pixel group. But I'd check your backlight power supply for bad connections, blown fuses, or check your led groups for bad leds.

Loud shrill noise coming from back of set


You have a bad color wheel. It will make a screeching or grinding noise.
that means its about to go out, your picture could freeze or pixel up before it gors completely but most likely you are going to go to turn it on and it just is not going to light up.

The color wheel is about a $300 repair...not really a job for a do it yourselfer though.

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. The DMD is another possibility.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 One simple test is to display menu and if it's affected then most like will be an issue w the DMD board.Found the complete set with color wheel and DMD included here: http://www.discount-merchant.com/SAMSUNG-30407272050-Light-Engine-w-Color-Wheel-p/1139314.htm Have a blessed one!
