Sounds like it's the wrong region disc. Try a disc that worked before and if it does than there is nothing wrong with your dvd player it is the disc you are trying to play that has the issue.

The SONY DVP FX720 is region free. SONY is notorious for putting out DVD players that will not play all types of DVDs.

Hi I also have a NS67P and I'm looking for the unlock code so it can play multi -region

PM: [email protected]

i have got teac 3120 , but it only plays pal 2 ...could you help me to unlock region 2 ....so i can have both region 2 and 4 to play/watch

Try this,
1) Plug the DVD Power Cord to the wall jack, but DO NOT Turn On the player;
2) With the Remote Control, press: Display, Top Menu, Clear and Power;
3) It will enter in the Service Mode;
4) Choose option 2 and then 4;
5) It will ask for an Input Code and Current Code (its 5 spaces), press 1245 and then Zero;
6) Leave all Zero erasing 1245, and on the bottom field all Zero too, then press Enter;
7) So the DVD Display will show a Zero (all Region-Free),     then press Power to Turn Off.
