try to clean the laser light with a cleaning cd, you put it in just like a normal cd and play it, it then cleans the lens on the laser. if that does not work check to see if the unit is damp, if so hair dryer might work. also try and hoover ( with crevice tool ) this will get out the dust if any BUT be carefull. i have tried this and it worked for me. AND another common mistake make sure your putting the cds in the right way up in the cd holder...GOOD LUCK
