Samsung HLP4663W color wheel replacement

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?? I have shaded lines on my screen. it is directly related to the dmd panel and the heat sink. what is the thermal medium (with fiber in it) between the heat sink and the DMD

    I fixed my problem. If you have dark shaded lines on the left or right of your screen, it is most likely the light tunnel assembly. Apparently the factory did not properly affix the four small mirrors in the tunnel assembly. It started with the vibration of the bad color wheel. It would move the mirrors slightly, causing the shaded area. Every time I took the light engine out, it moved the mirrors so when I put it back in it seemed like I was changing something. Today I got the new light tunnel($50+ship). One hour later, perfect picture.

    I have a DLP HL-P5663W 56" TV that I just changed the color wheel on and the color and picture quality is all wrong. I read the post about pulling the black jumper, but can not see anything that looks like a hardruve as it was described. Where exactly should i be looking. More info would be a great help.
