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?

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.
