after the upgrade/restore software procedure, the remote control may not work: you have to pair it with tv
the pairing procedure may change from a model to another, try this solution
tv in standby mode
press and hold the GREEN and RED buttons on the remote control for a few seconds: the standby led will blink 3/5 times to confirm the pairing
if it doesn't work, try again with the YELLOW and BLUE buttons, or YELLOW and GREEN buttons, eventually try with other combinations of the colored buttons
if a letter K appears on the screen: tv is in factory mode
after, when the remote control is paired, enter in service mode with the sequence MENU 1147
select Init TV or Shipping Init and press ok to reset the tv
