Does anybody have a detailed diagram of the internal cogs of the blueray drive.My ps3 stopped reading disks.I opened up my ps3 and cleaned the lens.The little white arms have come of with a couple of coggs and im unsure where they go.The blueray is now working but i have to play games with a open drive and replace games by placing that magnet wheel on the disk manually.Looks untidy would like to be able to put it all back together properly.
