Question about Samsung HL-P4667W 46" Rear Projection HDTV

1 Answer

We have a model HL R4667W--Our picture just went

We have a model HL R4667W--Our entire picture screen just went erratic (green "polka dot" squares) on all channels (over the air) and DVD does same thing. On some channels, it shows vertical bars instead of squares. Unplugging for 30 minutes didn't solve the problem. Any idea what went wrong and is it worth fixing?

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!

This is a problem with your digital board - the scaler circuit is faulty
estimate = 200-400
you could install yourself, we'd need a model number and version code to find the correct part.

Distorted image, lines, convergence?


If the pip is fine then the digital board is bad. Have it replaced by an authorized Samsung service center as the hex settings have to be copied from the dmd to the new digital board
