I push the power button, but nothing turns on

Please check the following items that could cause this problem:

1. Power cord connection

Ensure that the power cord is properly connected to the projector and plugged correctly into the electricity outlet.

2. Airflow passage obstruction

Please examine if the air inlet/outlet vents or air filter are clogged with dust or the airflow is blocked by some foreign object. If so, remove and clean the passage
