I purchase a LG dvd player sometime ago. It was a display set on sale $300 for a $500 set. Recently, it somehow cold booted, and some DVD I bought cannot be played. A message “Wrong regional code”.
I google a bit and found that I could hack the region code.
I got the instruction from videohelp.com/dvdhacks
1. Press “Home key on Remote Control
2. Using your cursor keys, move to “Setup” and press “Enter” on the RCU
3. Move cursor to “Lock” icon using down arrow on Remote Control
3. Press “Zero(0)” key on Remote Control 7 times (0-0-0-0-0-0-0)
A dialogue box with a message saying “Congratulations! Region Change Fee!”
I suspect my set was set to region free by the sales guys at the store when on display.
