Please try each of the following steps:
1. Verify Connections
Are all connections secured and have you checked that the other end of the cable is securely plugged in?
Are you using the proper connectors and color coding? If you are using a cable set-top box, the cable coming from wall should be connected to the "IN" jack on the cable box.
If you're not using a cable box, the cable coming from the wall should be connected to the "IN" jack on the VCR, DVD player or directly to the TV.
2. Check the TV
Is the proper input selected? (Channel 3, Input 1, Input 2, HDMI, etc.)
Are you an HD subscriber? If so, make sure your TV is on the correct input, i.e., component, HDMI, DVI.
No HD? Please ensure your TV is on channel 3.
3. Check the Cable Box
Is the cable box power on?
4. Reboot the Cable Box
Note: If this happens often, you might have a signal issue. If so, please contact us.
