This guide introduces troubleshooting solutions for common problems, helping you to find the problem quickly.
1. Projector Won’t Turn On
- If the projector cannot be turned on normally, check the power connection status and battery condition.
- Check whether the projector is overheated or not.
2. Irregular Image
- If the projection image and the screen are not matched, you can adjust the keystone correction.
- Make sure the projector and your screen are aligned.
- Check the aspect ratio of the projection image.
- If the projection image fails to occupy the screen, then you can adjust the height or angle of the projector.
3. Auto Shutdown
- Check whether there is a problem with the power supply.
- Make sure the projection environment temperature is normal. Most projectors have overheating protection and will shut down automatically.
4. Image Flicker or Noise
- The connection cable is too long, resulting in signal attenuation.
- It may be caused by limited bandwidth and requires a new cable.
5. Blurry Image
- Check whether the projector focus is adjusted.
- If the projector lens is dirty, clean the lens and projector filter.
- Check whether the projection image is too big or too small.
