The first thing i would suggest you to do is a hard reset by unpluging the the player for 30min and then try again.
If this does not solve your problem then please see if the player tries to read the disc.
Load a disc and listen.Does
the player make squealing noises or is it totally quiet? Squealing
noises may indicate that the player is trying to synchronize with the
disc but can't due to an obstruction on the lens or in the laser path
inside the pickup or a defect in the pickup. This can also be caused by
an intermittent signal problem due to a faulty ribbon cable.
silent means that the photo sensor is not getting any usable input from
the laser at all, meaning that the pickup is "blind" for lack of a

foreign matter on the lens or inside the pickup all the way to a
marginal or failed laser diode and/or photosensor array. This can also
be caused by a bad ribbon cable with one or more severed traces.
could try to clean the optics. This is the most common malfunction as
far as i know in all disc players. It would involve taking the cover
off and finding a way to expose the lense, and then cleaning it with a
very gentle brush. some players have a cover for the lense that swings
to the side during playing, this greatly reduces the chance of dust
accumulating, but its still worth the try.
If you actually see dust on the lense, then its just that simple. clean, close, play.
It may also be worth your while to check on the small shafting that
guides the carriage of the laser pickup. Dirt, grome, dust and
solidified lubricant can cause stoppage of the carriage and the laser
eye then fails to read the next track. Please refer to the image below.
If the problem still persists then you will have to get it repaired and thats the only solution..
