Hello! I bought xbox 360 without disc drive and I ordered new one from ebay. Dvd drive came and I changed the chip from the old one to the new one. Disc drive worked fine about 2 minutes and then it shut the game down and 2 left red lights showed(horizontal). Then it stopped working. Xbox works fine without disc drive, but disc drive won't read any discs. When I put disc to drive, it says "reading" and after while it says "Open tray" again.
