請問有人知道 LG DV8721N(DVD Player)如何解成全區的方法嗎?
有人告訴我此機可以
爬了很久還是找不到

LG DK7942P ALSO APPLIES TO LG DK 8621P (DVD/VCR UNIT)
The procedure is same as others, Turn on the unit, with remote, (no disc in player), press pause, then key 3 1 4 1 5 9
Instructions for changing region code appear on screen,
Set to Region or Disc you want to play, 1, 2, 3, 4, 5, 6, or 0 for all. Press pause again. Turn off machine.

Is the procedure of the DV8721N same as others?
I will try it.

>Set to Region or Disc you want to play, 1, 2, 3, 4, 5, 6, or 0 for all. >Press pause again. Turn off machine.

Do I just set it once or every disc?

I do appreciate your information.

How can I know the procedure is successful or yet?
