iRULU Projector Troubleshooting

In this section, blurry image problems, remote control problems, sound problems, and overheating problems will be introduced one by one.

iRULU Projector Blurry Image Troubleshooting

1. Adjust the focus button on the iRULU projector to make the image clear. Generally, the focus button is located on the top panel or the right-side panel.

2. Make sure the projection image is within the recommended screen size range of the iRULU projector. For example, iRULU BL20 has a screen size range of 32-200 inches, but the best projection size is 80 inches. When the projection size is 80 inches, the viewing effect is the best. If the screen size gets bigger than 80 inches, the viewing effect may be reduced.

3. Check whether the ambient light is too strong. The iRULU projector usually has an LED light source, whose brightness is not so high, and the viewing effect will be poor if the ambient light is too strong.

4. Check whether the projector lens is dirty. You can use the vacuum cleaner to clean the dust on the lens.

5. Check whether the iRULU projector and the screen are aligned.

6. Make sure the resolution is supported by the projector when you connect the projector to an external device.

  • Make sure the distance between the projector and the remote control is within effective range.
  • Make sure there is no block between the remote control and the projector.
  • Make sure there is no strong light or fluorescent light near the remote sensor, which can affect the signal.
  • If you are connecting the projector to a TV box or other streaming device, you need to use the remote control of the TV box to control the projector.

iRULU Projector No Sound Troubleshooting

  • Make sure the projector is not mute. You can try to adjust the volume using the remote control or the shortcut buttons on the projector panel.
  • Make sure there is no headphone plugged into the projector.
  • Make sure the audio format is supported by the projector. For example, you need to turn off the Dolby Digital plus when playing videos on some streaming platforms because some projector models don’t support this format.
  • Check whether the audio cables are connected correctly.

iRULU Projector Overheating Troubleshooting

  • Check whether the heat dissipation vents are blocked or not. No sundries should be placed around the vents. Do not cover any cloth on the projector for decoration.
