6. Troubleshooting

Common Issues and Solutions:

• No Image/Signal: Ensure all cables (HDMI, PC) are securely connected and the correct input source is selected on the projector. Verify the source device is powered on and outputting a signal.
• Image Distortion: Use the keystone adjustment to correct trapezoidal images. Ensure the projector is placed on a stable, level surface.
• Fuzzy/Unclear Image: Adjust the focus ring on the lens until the image is sharp. Ensure the lens is clean.
• Projector Noise: A faint fan noise is normal. Check if the projector is in "Silence" mode (if available) which might limit resolution. Ensure adequate ventilation to prevent overheating, which can increase fan speed.
• Light Border Around Image: This can occur with some projectors. Ensure your screen has a black velvet border or consider LED backlighting around the screen to minimize its visibility.
