LG DPBS930 portable dvd player SPECIFICATIONS

SOURCE: 7" LG Portable DVD Player DP271

A couple of solutions I found suggested the following:

1. Power up and press setup
2 Scroll down to LOCK
3 Press '0' (zero) seven times
4. A message may now appear with saying that the player is region free.
5. Power down then power up.

or

1. Remove any discs and power up the DVD
2. Press PAUSE
3. Enter 314159
4. The hidden region code menu may now appear.
5. Set code you want- 0 for multiregion, 1 for region 1 and so on
6. Press PAUSE
7. Power down then power up

Hope that helps.
