I have followed that sequence from my Remote and nothing happens. Just the main menu appears with last button press "menu".Remote control: Power off -> up -> right -> up -> left -> menu
Choose "Factory Reset" from Main Service Menu
Is this "Factory Reset" the same as the one that I find in the "Menu / Setup / Reset / Reset to Default" ?
What is the "Main Service Menu"? Is it another Menu different from the normal "Main Menu" with some more hidden options for maintenance service?
