CD player repair is sometimes required in order for your CDs to play properly. However, because of the technology involved most CD drive or CD player repair should be performed by a qualified technician.
It often happens that a CD is placed in a player or drive and the disc cannot be read. There are several reasons why the disc is not readable. First, it could be an issue with the CD. The compact disk may be dirty, physically damaged, or chemically degraded.
Also, there may be a problem with the CD that is not visible. For example, the error rate on the CD may be high, too high for the error correction system to deal with and thus for the CD drive or CD player to play the disc. Therefore, CD player repair is not always necessary when a disc does not play. Inspect the disc for dirt or damage and if noticed, use an appropriate remedy to restore the disc to good condition. If the restored CD is still not readable, then it could be that the error rate is too high. If this is the case, then there is not much you can do to make the disc playable. The only option is to simply use another player or drive to read the CD. Whenever a CD will not play in a drive, one of the easiest things to do is to use another player or drive to attempt to read the disc.
There are no standards for players and therefore, player or drive performance or ability to read discs can vary widely. Some drives will be able to read discs with high error rates and some drives will not. Some drives can tolerate discs with some damage whereas others cannot. Older or bargain drives tend to have more problems with discs than many of the newer drives that are available.
Next, if the disc is not damaged and several drives will not play the disc, then it is likely the player that is the problem and CD player repair or CD drive repair is required. Unfortunately, there is not much that can be done to repair CD equipment unless you have experience in repairing this equipment or are a qualified technician in CD equipment repair. However, before taking your drive to a specialist, one thing that can be done is to clean the lens of the equipment. The lens focuses the laser light onto the disc and if the lens is dirty then the laser light intensity may be too low and/or may be diverted away from the disc. Products to clean lenses are available and consist basically of a CD disc with some very small soft brushes attached to the disc surface. When the disc is inserted in the drive, it spins and the brushes lightly wipe the lens clean. Avoid any home made repair CDs as these can destroy your player and result in more extensive CD player or drive repair.
Finally, if it has been established that the drive is the problem, it may not be worth pursuing CD drive repair or CD player repair. With the price of drives fairly low and the option to purchase external drives being available, it may be a better choice to simply replace the equipment rather than having older equipment repaired.
All of the above information is also applicable to DVDs and Blu-ray discs and drives.
