When this happens it is usually an indication that the laser pickup assembly lens needs to be cleaned or that it has/is failing and needs to be replaced. Try resetting the unit and if that does not help then using a cd cleaning disc to see if that fixes the problem, normally it does not and that is due to it needing to be replaced.
Thank you!- Joe
