Why won't my NEC PA723U turn on?

If your NEC Projector doesn't turn on, it might be due to its internal temperature being too hot or too cool as a protective measure. Wait a moment and try turning it on again. Also, the lamp may fail to light. Wait a full minute and then turn on the power again. If you're using the projector at high altitudes (approximately 5500 feet/1700 meters or higher), make sure to set the [FAN MODE] to [HIGH ALTITUDE] to prevent overheating.
