First of you should make sure that your laser is clean. Also make sure you see your laser move properly. If the cleaning does not work (some people use a commercially available laser lens cleaning CD) you should start thinking about disassembling your Saturn. Here are some really good instructions. Once you got this accomplished, you will find a little orange "dial" which is actually an adjustable potentiometer. It is just above the cable that connects the laser assembly to the circuit board. When you turn the dial counter-clockwise, the laser will seem to get dimmer, when you turn it clockwise you will notice that the disk/drive will start spinning. (here is a video to help you with the laser repair) That is where I would start. OF course, make sure that you MARK THE SPOT where you start from. MARK IT FOR SURE so that you do not lose the starting point. But, start cleaning your laser first. Good Luck.
