DVD does not recognize disc

hi..if a lense cleaner  dont solve the prolbem then you can replace the laser unit itself if that type of cleaning also dont work means and you think you are capable of taking the casing off make sure you switch it off first this should send the laser to the center of the laser tray if you take the case off and it is not in the center it might just be that it has got stucked sometimes gently pushing it back to the middle will get it working again if it is already in the middle then it could be that the laser needs replacing but if not in middle push gently dont shake the device too much it  should be quite hard to push any way when you push back to middle try a disk  but please make sure you dont touch anything while device is it is plugged in if nothing works then it probably is the laser but before you do anything as soon as you get the case off switch it on and put a dvd in and make sure the disk is spinning.. if its not spinning then ur laser unit is damaged..

thank u
