Hello this worked on my set
1 Turn on then select DVD from DVD/TV button then and open disc tray leave open
2 Press setup button twice then enter 1379 on remote
3 Region code will display 2 press the down arrow button which is under the Play/Enter button till region code is set to 0
4 Press setup then exit
This method also works on some cheap DVD players such as Cinetec from argos good luck cos its taken me years to find this code and it works fine
