Hello Trence,
After searching for a solution to your problem, checking private and public database's for region hacks. I was unable to find a solution specifically for your make and model of dvd player. ( There are less known hacks for built in dvd players)
There is one universal code for
Polaroid dvd players altho this is not 100% sure to work for you but you can try it.
1. Turn on unit
2. Open lid
(All instructions on remote)
3. Press SETUP
4. Use the down-arrow to
reach PREFERENCES menu
5. Press ENTER
6. Use the down-arrow to reach
DEFAULTS menu
7. Press SETUP
8. Press 1379 (You will see ---- appear one
at a time)
9. Press ENTER until you reach desired region (9 for region-free)
10. Press STOP
Post back if this does in fact work for you, if it does not then honestly there is no hack for your built in dvd player. I have put in a request with the private site I belong to and they will have there experts try and find a process that will work with your dvd player.
