If an electrical outlet does not supply enough voltage to the cable device, this can lead to the device not working correctly or even being switched on. It is therefore recommended to replace the connector for the signal amplifier and other cable devices. Check if the problem persists afterward.

Change source

The reduced power source can be a significant cause of this type of error. If the power outputs cannot provide sufficient power sources, switch the outputs of the signal amplifier and other devices to a single account to make a reliable connection.
