Question about Samsung HL-P4667W 46" Rear Projection HDTV

1 Answer

My Samsung HL-P4667W 46 in. DLP television picture is not displaying all of the colors in the spectrum. I recently replaced the color wheel on this set (in February) and it seemed to work properly for approximately a month and a half - all the colors were displayed. However, approximately a week ago most of the color was gone - the set is now primarily displaying red and green.

Depending on where you bought the color wheel there is something you should know.

Some of these sets will display this problem when the wheel is replaced. On the DMD board which is the metal box that is part of the light engine where the color wheel is located there is a opening with a small jumper plug.

I have seen it cause this kind of problem but usually it does from the moment you replace the wheel. If you remove the back cover and look at the silver box with lots of little round holes you should be able to see it.

It is a two pin plug with a flat metal piece across the top---if it is there remove it carefully with some small needle nose pliers or a hemostat.

If color returns to normal---you found your trouble. Most places that sell replacement color wheels do not tell you about this or do not know

Let me know if you have questions or if it resolved your problem.

I have a SAMSUNG 46" DLP HL-P4663w, No picture but have sound. All three lights are flashing at on/off button. Installed new lamp ( BP96-00826A ) still no light. There is a loud humming sound.

This is and indication of a bad color wheel assembly, you can replace the color wheel yourself, there are lots of Youtubes videos on how to do this.

Samsung had an issue with there prizms falling apart. The prizm is found just past the color wheel in the light engine. This is pretty complicated and best left to a pro.

Dlp has no picture only flickering lamp & timer lights.

Verify color wheel is reconnected, color wheel needs to get up to speed before lamp strikes

This is most likely your Digital Processor Module. So far most all makes are selling them as a complete Light Engine Assembly which includes the light tunnel, digital module and color wheel. They are rather expensive, some are in the $800.00 range, a few more dollars and you have a new set.
