This is a relatively common problem when the optics get dirty. If you can reach the lens, try cleaning it using a cotton swab and alcohol. Don't bother with the "cleaning discs" available as all they can do is bruch off the dust. These lenses sometimes get a smoke or dirt film on them that the brushes can not celan.

Keep us posted.

Buy A CD Lens Cleaner and put it in to the CD Player and keep retrying until the drive plays it and then follow the instructions for the CD Lens Cleaner after its finished try playing a CD if it still wont play try another disc and if it does not play that try reset the player by unplugging it for five seconds if it still wont play the CD drive has failed in the drive and you need a new stereo. Stereos dont last forever so dont be surprised if you need to buy a new one

I've been messing with mine because it says no disc and I messed it up so it started saying this error. Unscrew the screws around the top (4 screws) and slide off the top cover. The small black rectangular box that sits over the eye/laser can be removed carefully by compressing the clips. Then the cd tray can be removed. I figured out this error was coming up because I had the tray out of alignment... so try to see if that's the problem with yours... also the eye itself slides (the entire mechanism it's on... slides away from and towards the place where the cd sits to be lifted and read) and it should be as close as possible to the area that lifts the cd. Sorry if this isn't making sense... trying to explain in the best way possible. The tray being out of alignment causes that error though.
