The power turns off or does not come on.

The inside is too hot, or the projector has been working in an area of high temperature.

Place the projector correctly so the intake and exhaust fan's holes are not covered.

Turn the projector off, and leave it for a while, and turn it on again.

Clean the air filter. 61
