Just unlocked my LG LH-W750TA DVD Surround Sound player's region code and thought I would share it. Used the following method used for another LG Player:
Using the Remote: 1. Power On 2. Open Tray 3. Press 0000 4. TV will show blue screen with the following two lines: a. Region Edit: b. Region Code: 5. Enter 0 in Region Edit line 6. Press Enter 7. Press pause button 8. Power Off
When you power back on, the DVD player will be region free. Good Luck!!
