It wont play the dvd it is not the dvd its the player

The dvd lens in your system is probably dirty from sitting and normal use. Every so often we are supposed to clean the lens. Taking it apart is a more complicated process but purchasing a lens cleaning kit and cd and following the instructions below should do the trick.

• DVD lens cleaning kit, you can purchase at many local stores or online. Walmart should have it as well as amazon.

1. Place the lens cleaning disk into your DVD player's tray bristle side down. (The DVD will have a small row of fine bristles used to clean the DVD heads.) Push in the tray.
   
2. Listen to the instructions for your DVD head cleaner. You should be able to find the instructions on Track 1 of the DVD cleaning disk.
   
3. Choose an option from the on-screen prompts. You will have choices like express cleaning or standard.
   
4. Remove the cleaning disk once it has run its course. Your Panasonic DVD player heads should now be clean
