Methods and systems for diagnosing projection device failure

Projection device failure may be diagnosed by sensing improper operation of projection lamp ignitor circuitry. An ignitor failure indicator may be activated based on a sensed failure in the operation of the lamp ignitor circuitry to prevent incorrect projection lamp failure notification.
