He encontrado esto en dvdrhelp, por si te sirve:
- Make sure there is no disc in the player
- Unplug dvd player
- Plug system back in while holding the "Open/Close" and the "play" buttons (ON THE PLAYER, NOT the remote)
- The word "Test" should come up on the player Display
- Press "9" on the remote until the display on the player says "00A0 0000"
- Press "Standby/on" (remote or player)
- Wait 15 seconds
- Turn player back on
Ya nos contarás.
