  The Panasonic Projector may not power on due to several reasons. Ensure the power cord is securely connected and that the wall outlet has an electric supply. Also, check if the circuit breakers have tripped and reset them if necessary. If the TEMP or LAMP indicator is lit or flashing, refer to the indicator guide. Verify that the lamp unit cover is securely installed and that the CONTROL PANEL settings in the PROJECTOR SETUP menu are validated.
