My coby 514 wont play DVD 9 disc - Coby DVD-514 DVD Player

SOURCE: Dratted Coby TF-DVD7100 Portable DVD player not working!

Its defective. Coby doesn't repair the units. The lense is off balance which is causing the laser to not read the dvd/cd.

try running an optical disk cleaner it worked for me but I have to clean often.........a cheap fix if it works.

Did you make the disk if you made the disk your computer has to give it a digital signature so the DVD player can read it if you're using a regular DVD then I would very carefully using rubbing alcohol and Q tip clean the actual laser I would be very careful doing this if too much rubbing alcohol is on the Q tip it will ruin the laser you can also try resetting the DVD player by taking out the battery and unplugging it from any power source and leave it that way for at least 20 seconds to a minute if that doesn't work you might have something else wrong
