Likely corrupt/bad main board due to watchdog triggering. People on here have not had much success on these, except by replacing the main board. Access service menu and try reset (from standby Info Menu Mute Power.)

More likely it was just a bad board to begin with (corrupt firmware is possible), if you got good picture it would not be incorrect.
