Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Samsung HLP4663W I have changed Bulb, Ballast, and Color Wheel, Yes, removed the Jumper and set to CW2 too!(color wheel had no sticker with CCA Values or Actuator or Index Delay Values on it) I set the Index delay to 47 and the Actuator to 113 as per the 'Service Bulletin' from Samsung. The same color and picture problem still exists, that caused me to change the color wheel in the first place. I have heard horror stories about changing the DMD board. Is this TV worth keeping now??? Please help as this is my disabled wife's TV and she has missed it now for 5 months. Or have we been conned by the people who sold us the colorwheel, they say we do not need all the value numbers.

Samsung HLP4663w. After replacing the Ballast, Bulb and Color Wheel (color wheel came without the CCA values and the Actuator and Index delay values) we still have the same color and picture problems. Do...


if the picture is blue green there is a jumper to be removed on the dmd board on connector cn810--the index delay should be between 40 and 50 for optimum color --or adjusted for best flesh tone also in the options the cw setting should be set for cw2

The jumper if it has it usually causes the color to look funny blue instead of normal.

It is located on the DMD board--the metal box on the light engine where the two plugs from the color wheel are.

It will be in a small opening on the metal shield that covers it--small and rectangular in shape--it has a small metal tab across it--it jumps two pins--

if it is there with a hemostat or small needle nose pliers pull it carefully out and see what you have--The CCA adjustments are done in the TECH MENU--look to see first if the jumper is there and remove it.

A lot of places that sell the wheel do not tell people about this.

Here's a good article on the Color Wheel

It says if your red and blue colors are reversed removing the jumper should fix the issue.

Problem with new color wheel


No I am still having issues with my color (mostly dark shadows and black). I never did pull out the jumper, I was never exactly sure which part it was, and the part that I though was the jumper would not come out. I did not change the CCA setting because I removed the sticker from the color wheel with the numbers on it. I can get the screen with all of the CCA numbers on it, but I have no idea where to start to change any of those numbers. I have tried looking for the CCA numbers but have had no luck finding them. If you have them, if there is any way to forward them to me that would be a great help. I am almost ready to call a technician to come out to try to fix the color.

If the color wheel you replaced was the BP96-00674A, it would have come with the proper cca adjustments for that particular wheel. You must enter the service menu and reset the cca's for proper color.

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.
