Follow the steps below to troubleshoot an HDMI switch that is not passing video:
- Unplug all HDMI and power cables, and leave the switch unplugged for fifteen minutes.
- Verify that the HDMI cables are working by testing directly with the TV (without the switch).
- Connect each video device to the switch alone to determine whether they work separately.
- If the inputs work separately, connect them all together. If the video signal drops, note which device was connected.
- Test with cables that are 15 feet or shorter on both the Input and Output of the switch.
- Move the device to a different port.
- Try toggling auto-switching off or on. To toggle auto-switching, hold the Switch button for three seconds.
Some devices may also “fall asleep”, go into low-power modes, or keep their HDMI ports active while powered off. This may allow the device to be selected on the switch even though no video will be displayed, or may prevent the device from triggering auto-switching when it is powered on.
Turning off such “low-power”, “Sleep”, and “Network Only” modes in the device’s settings can help, when possible. More information about Auto-Switching issues is available in the article below:
