EIKI Projector Troubleshooting

In this section, we will introduce some problems such as air filters, remote, automatic shutoff, sound problems, image problems, etc.

EIKI Projector Filter Warning

If there is a filter warning from the projector, the air filter of the projector may be clogged. You need to clean the air filter to solve the problem.

To avoid the problem, you need to place the projector in a cool place without too much dust and clean the air filter regularly according to the steps below.

  1. Turn off the projector firstly, then disconnect the power cord from the outlet.
  2. Turn over the EIKI projector and remove the air filters by pulling the latches upward.
  3. Clean the air filters with a brush or rinse them softly.
  4. When cleaning the air filters by rinsing, dry them well. Replace the air filters properly. Make sure that the air filters are fully inserted.

EIKI Projector Remote Not Working

  • Check whether the projector’s remote control is out of power. Try to replace a pair of new batteries for the projector. 
  • Make sure there are no blocks between the projector and the remote control.
  • Check whether the distance between the projector and the remote control is too far. The distance should be within 5m to achieve a quick response.
  • Pay attention to the pointing angle when using the projector. To improve the response, point the remote to the projector within 60 degrees.
  • Avoid using strong light illuminating the projector sensor.

EIKI Projector Keeps Shutting Off

If the EIKI projector keeps shutting off, you can check one of the following factors, including air filter, temperature, lamp status, and internal functionality.

Clogged Air Filter

When the air filter sensor detects the air filter is clogged, the projector shuts off automatically to protect the projector. You can try to replace an air filter cartridge or clean the air filter to solve the problem.


If the projector is overheated or the temperature rises too high, the sensor of the projector will automatically turn off the lamp and the STATUS indicator(s) will start blinking.

Broken Lamp

If the lamp of the EIKI projector reaches its end of life or the lamp is broken, the projector will shut off automatically. You can replace a matched lamp for the EIKI projector and then reset the lamp counter on the projector.

Internal Failure

When the projector has an internal failure, the projector will shut off with either a combination of LEDs flashing or a solid warning LED depending on the model. The projector cannot be restarted unless the power cord is disconnected from the projector and then reconnected. When this happens, contact the Eiki technical support line for assistance.

EIKI Projector Won’t Turn On

  • Check whether the projector is connected to power correctly.
  • Check whether the lamp of the projector is out of life. If yes, replace a new lamp for the projector.
  • Check whether the EIKI projector is overheated. If yes, cool the projector down first and try to turn it on later.
  • The EIKI projector may be in sleep mode. Press and hold the power button to start the projector.
