Question about Lite On (SHW-1635S) DVD RW Dual Layer Burner

1 Answer

My Lite On DVDRW will not recognize any audio cd's...

Hello. I have a Lite On DVDRW SHW-1635S that came bundled with my PC when I bought it about 2 years ago.
Up until just recently, I have used it to listen to and burn audio CD's....and to watch and burn DVD's. It has always worked great.
Just about a week ago, all of a sudden it would not recognize that there was an audio cd (of ANY kind) in the drive. If I put an audio cd (either burned or store-bought) in the drive, it does not recognize that there is a disk of any kind in the drive. Oddly enough, it still plays and burns any DVD though. No problem at all with any of the DVD functions.
Was just wondering if there is any way to correct this problem, or is the drive just simply "fried" and it's time to buy a new one?
Any responses would be greatly appreciated....

Hi PhxROcker,

In these drives there are two lasers and two pick-up sensors. Normally in a combined head. One set is used for the DVD and the other is used for the CD. From you description it sounds like the optical sensor for the CD laser has expired! When you place a CD into the drive a small amount of information is read by the drive that identifies the disc type, manufacturer, it's status, capacity etc. If the drive cannot read this then it thinks nothing is present.

If you insert a disc does the LED on the front the the unit flash a few times while it spins the disc. Does it do this repeatedly? If it fails to read the disc does the LED stop blinking and the drive no longer spins the disc? If this is the case then your drive may indeed be faulty.

Sorry I could not be of any further assistance.


Spare head 2.
