When an error occurs, the Power supply\Standby or Lamp LED will flash to a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas. If the error occur simultaneously, the one that corresponds to the fewest flashes is identified first.
