How to fix this?

Here are seven fixes you can try out. 

Check your connections

The first thing you should do is check to see if all the incoming connections to your set-top box are properly in place and that there’s no damage to the cable. Loose connections are one of the leading causes of this error as they don’t let the signal pass through to the device uninterrupted. 

Check service status

The next thing to do is checking Spectrum’s service status. If your service provider is facing an outage, chances are you’ll run into problems as well. Since the error indicates no signal on the target device, there’s a chance that your service provider may be facing some problems on their end.
