Okay, so I have gotten the colorwheel out of my 42" samsung. I went back and checked the archives and found that this is what you say was making the buzzing sound in my tv. So I found a couple of instruction videos that showed how to do this and got it done. Now I need to know if the part number I'm looking for is correct and how do I know that this is really the problem? bp96-00674a and is there any way to know if it is actually the color wheel? I don't want to sink a lot of money into it to find out that this isn't it at all.The colorwheel seems snug ,no wobble, but there seems to be a small line of no color on the wheel, is this normal. I also pulled the connector off of the wire to the main board. Help please, I really loved my samsung tv and would like to be able to fix it!
