Guys from India, I wonder if there is service menu you can go into and maybe change the region, and the tv tuner could work for PAL system. I don't know, but if you look through the PA70g thread there is info on getting into service menu with special remote and do changes that way.
Again, I don't know for sure if it is possible to switch to different region , but what do you have to lose in researching it and reporting back.
I was thinking of picking up one of the special LG remotes that put it into service mode.
I guess the other option is to call LG and see what they say. I know there is Korean version of the pa75 and other versions, but not sure if service menu could change that or if firmware version could change it.
