The first thing you should consider is why the projector isn’t turning on because the problem could be one of a few things. Is it just the remote? Try changing the batteries and testing it with another projector. Does the projector have power? If you can see a green LED on the unit, then it has power. Do any of the LEDs blink when you press the power button? Take note of which light blinks and how many times. Has the lamp recently been replaced? Make sure the lamp door is completely closed. Perhaps the lamp needs to be changed. Borrow a lamp from another projector just like yours and see if it comes on.
Once you have gathered all of this information, please contact Technical Support.
