I tried to change my LG HT963TA to region free without success. One post advises the following

"go to the dvd's setup menu, lock, move to the 3rd level, enter a new password 1111 (or whatever you want), re-enter the password, enter code for your geographic area. I am in Canada but entered France (the country codes are on page 21 of your user guide). Powered off/on dvd player and all regions now work."

I tried that and also tried several other contries but i still get the Check Region code message. Please help
