I have a lg 47lg-50 lcd tv. It started bliinking a function not available message . And none of the buttons on the tv or remote responded . I change the main board . It seemed ok for a few weeks . Then it started to turn on by itself . Then the blinking started again and the buttons all stoped working . Every once and awhile the blinking stops and everything works . Also when it is blinking it will not shut off .

Check the caps in the psu.
It could also be the keyboard.
If a buttom is constant aktivated it locks everythingelse.
