7. Troubleshooting Common Issues 

Q: Power light is off and product is not working. How can I fix this? 

A: First, please check the following items: 

1.

 

Ensure that your device’s HDMI input device is properly connected and it is powered on.

 

2.

 

Check that the HDMI port is selected correctly and is active. 

Q: My display flickers when I use the switcher. What could be causing this? 

A: This may be caused by one or more of the following: 

1.

 

Make sure that the HDMI cable and switcher are securely connected. 

2.

 

Ensure that the HDMI cable is 2.1 standard, and the length is under the switcher limited 
length of 1.5 meters HDMI in and out at 8K/60Hz 4:4:4, 4K@60Hz can reach 4M in and 
4M out. 

3.

 

Change to the other port and see if the issue persists. 

Q: The switcher auto function ca

n’t work normally. What could be causing this?

 

For the auto-switch to work properly, the newly connected source device should be powered on. 
If the HDMI source if not powered or is in stand-by mode, the switcher may not detect it and 

won’t output audio or 

video.
