I think I fixed my delema with the grining noise when I was replacing my laser, since I tightened the adjustment screw lol. Now my CD won't spin. I does a 1/20 of a spin when I reset or close my cd tray, but it goes directly to the browser screen like it doesnt notice I have a CD in. It does this on ANY CD. Also, there is a screw in the middle of the top part of the expansion bay (take PS2 out of bottom cover, flip it over, and remove bottom of expansion bay)that seems to be going into the laser area and sticking into a crevice of the laser, (where another screw on the laser is) thus limiting the amount of verticle movement of the laser. Is this it's purpose? Is this where it is supposed to be(in the laser)? Maybe this is the source of my cd spinning problem?
