No disc found

Hi,

Most DVD players that would not recognize and/or play a disc even with a known good disc inside signifies that the laser eye/lens is not reading the disc. This could probably be attributed to:
1. dirty, damaged, inverted, blank, un-finalized burned CDs or DVDs;
2. defective, weak, dirty/dusty burned-out laser eye/lens;
3. defective slider shafting (where the laser eye's carriage moves) or some other components.

A few things you can try:
1. Use a CD cleaner (readily available from most computer shops);
2. use a can of compressed air and blow through the inside of the loaded disc area;
3. gently tap on the top cover where you estimate the reading/laser eye/lens would be;
4. gently press on the tray door once the disc is loaded.

Should this not be corrective, perhaps your best bet would be to seek the services of a qualified professional such as those in a Service Center. Alternately, your friendly neighborhood electronic shop should do just fine.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kindest regards.
