A little while back my Xbox 360 phat finally got to the point where it would no longer read discs. After foolishly messing around with it without a multimeter, I was pretty sure I screwed my laser up. So, I sent away for a laser, a multimeter, and a soldering iron on my liteon disc drive. After fixing a problem with the laser arm screw not screwing in tightly enough, I finally got it so my new laser could stay attached to the worm motor. Now, despite a red laser coming up, my Xbox with new laser still will not read discs. I'm pretty sure I soldered correctly as I see the three dots people talk about, and I feel that it should work seeing as though the laser lights up. I took a multimeter reading of the new laser and found that the one on the left (DVD I think?) read about 4.31 whereas the one one the right (CD?) read about .81. At this point, I really don't know what I should do next. Should I try a pot fix on the new laser even though the factory settings sound right? Did I mess something else up when trying to fix the drive? Btw, it is stock disc drive. Haven't modded or flashed anything.
