Samsung HLP4663W Black Solarization

I have a Samsung HLP4663W DLP set. The color wheel was recently replaced. When there is anything black displayed on the screen, the black portions look "solarized"

Does anyone know what causes this and the fix? Thanks

The speed of the color wheel needs to adjusted or the CCA values. Both are found in the service menu . If you paid a company to fix the TV, call them and tell them that they forgot to perform these alignments. If you did the repair yourself, you'll have to call around for a price to have a Samsung service center perform these adjustments. I don't recommend consumers access the service menus of modern TVs because one wrong button push and you may cause irrepairable changes to the TV's proper operation.

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!

Samsung DLP TV shows green color where color should be black


This could be your video board going bad where your input cables are connected --OR-- the color wheel going bad. Hard to tell without a photo or reference though. Try swapping the cables first... and listen for any winding or whirring sounds.

Dark greys appear a dull green.


could be a jumper that needs to be removed on the DMD board, or a setting in the factory mode, mute-182-power will get you in there

Samsung HLP4663W color wheel replacement


When I removed the jumper wire the screen color problems I experienced after changing the color wheel were fixed completely. I did not need to reset the CCA values (which came with my color wheel, on a separate sticker). If you have a black bracket blocking access to the jumper wire, as I did, you can access the jumper wire by removing the fan shown just to the left of the yellow and white sticker; there are two screws attaching the fan to the chassis below it. Next, remove the two screws that hold the silver clamshell (the housing for the circuit board) halves together. These screws are right behind where the fan just was, on either side of the protruding fins. They each have a spring under the screw head. You can then pull the visible half of the silver housing forward (with the bracket attached). You will then have access to the entire circuit board. Look for CN810 - it is located right behind where that bracket just was when it was all put together. Pull the tiny black plastic part (that has the jumper wire) off of the pins. Then reassemble the housing and put the fan back on.
