What to Check First

  1. For safety, turn off the power switch and remove the plug from the socket.
  2. Contact the place of purchase or authorized service center for product inspection.
  3. Do not attempt to repair the product yourself.
  4. Inside the product, a fan runs at high speed to cool down the components.
  5. Are you hearing a whirring, rumbling, or rattling noise? Does the noise become louder suddenly?
  6. When the projector starts, it is normal to hear an electric noise from internal circuits or a whirring sound from the fan. However, if you experience a rattling noise, check if the product is securely fastened to the brackets or tripod. If you encounter blowing sound or unusually loud noise, please follow the instructions below.
  7. ➔ Please remove any objects obstructing the air vent to ensure proper airflow.
  8. If the internal parts are overheated, the risk of product failure or fire significantly increases. Please ensure that the product is well-ventilated through smooth air exchange.
  9. ➔ Open the window to improve ventilation.
  10. When the indoor temperature is high, the efficiency of ventilation decreases as the fan is required to use hot air for cooling. If the indoor temperature exceeds 40℃ (104℉), the product may power off to mitigate the risk of product failure or fire. In case of high indoor temperatures, it is recommended to open windows to allow the fresh air to circulate inside. If the product has been used for an extended period, it is advisable to turn off the power and allow the internal components to cool down.

Why This Can Happen

Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
