Try this: 1 Press Menu 2 Factory settings 3 type in code ( 0000) 4 press ok. this will delete channels. 5 Installation 6 Change provider (Eg n*L etc)to which ever one used in your area. 7 autoscan ( when it says *** channels found , exit back out all the way until u are back at the scrambled/no signal 'tv' screen) 8 Hit menu again 9 Type 1570 11 new screen appears , change EMU to on Exit to view. You will have to re-sort your channels/favs but worth a go. If this still does not work turn off you box from the back switch for a minute and then autoscan again, may sure you have the correct provider selected and key emu is on.
