Steps of Regular Troubleshooting Routine


1. Power: Make sure all devices are powered on (source, switcher and display devices).
2. Indicator: Make sure LED indicators of switcher are normal according to user manual.
3. Devices: Make sure picture can be shown normally when connecting sources to display device directly.
4. Cable: Plug in and out HDMI cable or change to another HDMI cable. 
Please make sure the cable length is within the available transmission range according to Specification section. 

5. Compatibility: Please test other source and display devices to determine if it is a compatibility issue.


1.        How to deal with video flash or cut off during the installation?

 Verify that all the indicators are solid on. If not, please check if the HDMI/USB cables are wellconnected.

Verify that the display device works properly and that the source devices have normal signaloutput. Also, make sure HDMI sources are under 4K@60Hz4:2:0 8bit.

2.        How to deal with a weak or not working IR signal?

Make sure the IR cables correctly installed according to the diagram above.

Pay attention to the control angle and distance as below. The control

3.        Why all LED indicatorsare normal but the display cannot output signal?

Since the switcher 4KSW51 supports up to 4K@60Hz 4:2:0 8bit, when the resolutions for both source and display devices are 4K@60Hz 4:4:4 8bit, the display device cannot output signal even if all LED indicators are normal.

To fix this, please set the source devices' resolution to 4K@60Hz 4:2:0 8bit or lower.
