8. Troubleshooting & Maintenance

1) When there is a color losing or no video signal output, maybe the cables have already broken or haven’t been connected well.

2) When EDID management does not work normally, probably the HDMI cable is broken at the output end.

3) When switching, there is a blank screen on the displayer, maybe the displayer does not support the resolution of the video source. Switch again or manage the EDID data manually to make the resolution of the video source automatically compliant with the output resolution.

4) When user cannot control the switcher by computer through its COM port, please check the COM port number in the software, and make sure the COM port is in good condition and the communication protocol is correct.

5) When switching , there is no output image:

 Check if there is any signal at the input.

 Check if there is any signal at the output.

If there is no signal input/output, maybe the input/output cables broken or the connectors loosen, please change for another cable.

 Check if the output port number is the same with the controlled one.

 If it is still the same after the above checking, maybe there is something wrong in the switcher. Please send it to the dealer for repairing.

6) If the static becomes stronger when connecting the video/audio connectors, it probably due to bad grounding, please check the grounding and make sure it connected well; otherwise it would damage the switcher.

7) If the switcher cannot be controlled through the RS232 port, front panel buttons or by the IR remote, the unit may have already been broken. Please send it to the dealer for repairing.
