1. Projector not turning on

For starters, if your projector is not turning on, check the obvious things. Make sure that it’s plugged into an outlet and that the plug is securely connected to the projector. Also make sure that you’ve inserted all necessary memory cards or DVDs into your device.

If none of these fixes work, then check your power button. Make sure it’s turned on and that you haven’t accidentally turned it off or changed its position.

2. Projector shuts off suddenly

If your projector shuts off suddenly, try removing the memory cards or DVDs that are inserted in it. If the problem persists, then attempt to restart it again.
