Bad disk

if this disk plays on other sources then it is not the disk and sounds like it is a problem with the laser or the motor that pushes the laser along the disk if it dont play no disk at all then it is the layser if you have used a good quality lense cleaner and that didnt cure it then you could try if you are ok taking the case off leave it for 24 hours to make sure no electric is running through it and look where the laser eye is it should be neer the middle where the center of the cd sits if it isnt gently push it back to the middle this will recalibrate your laser then put it back together and try again if this dont work you will then have to get a replacement laser unit these can be expensive but you should be able to fit it your self as the wire areconected by conector but before you do this make sure you use a good lense cleaner as the cheaper ones wont work all the time and listen if the cd is spinning in the unit if its not spinning then you need replace the unit if you dont feel up to it then a repair shop will do this for you their si no way round it other than to replaceit they usually last the life of the warranty they are made to last no longer hope this is some help but not much more you can do
