Question about Samsung HLP4663W 46" Rear Projection HDTV
I just replaced the color wheel in my Samsung HLP4663W DLp tv. Now the color is off and the picture in not clear like HD should be. What should I do to fix this problem? I have read that removing the "jumper" near the color wheel could solve this problem, is that true and how do I remove it??
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.

A tv repairman here in Denver came today and fixed the color wheel on my Samsung hlp-4663W. Though it cost me $400, the repair was done in 10 minutes. The guy made it look extremely easy. He also wrote on the invoice that the color wheel was defective, telling me that many of his customers have been able to get the cost of the repair reimbursed by Samsung because they know there was a design flaw in the color wheels. I will try and fight that battle tomorrow. My color wheel was a non-bearing wheel, but he said the glue on it failed, causing half of it to shatter.

To get to the service menu start with the tv off and then press mute > 1 > 8 > 2 > power on the remote the tv will come on with the menu displayed

Once in the menu, I'm having problem setting all the value. I was able to set x, y, but not Y, lv, index delay actuator. what are those.

We just went thru hell solving that problem. Yes, there is a little black jumper like that used on a computer board that needs to be pulled. The jumper is pretty close to the middle of the bottom of set, just below a yellow tag.

The jumper is on the dmd bd. close to the dlp chip heat sink. Need tweesers or small needle nose to slide the jumper off of the two small pins. Each BP96-00674A color wheel has the new CCA settings taped to the new wheel. You must enter the the service menu and reset the CCA's for this color wheel.
