hi.
(** The responsibility belongs to you.)
Log in to this menu on your TV. (toolOPT6)
Take a picture of this menu. (Don't lose this picture just in case)
Then replace the red marked place in the picture I sent with the numbers in the picture. (change it to : 273861641)
and take another picture.
compare it with the first picture. Only the blue area should be different. (on/off)
