The correct sollution is "User settings, 2&8, User settings" if the LUI (Local User Interface" hangs or locks the possibilty of entering the Service mode, press (the yellow) Clear/Restet button and try again.
The Yellow button will work as a release button, if you fail to enter the right combination.
Good luck!
"User setting" a.k.a.: star boy, nose star, fan brain or star fellow
