- Verify your connections:
- Are all of your connections secure and hand tight?
- Are you using the proper connectors and color coding?
- Are you using a set-top box? If so, is the cable coming from the wall connected to the “IN” jack on the cable box?
- If you’re not using a cable box, is the cable coming from the wall connected to the “IN” jack on either your auxiliary devices (VCR, DVD Player) or your TV?
- Check the TV:
- Is the proper input selected (i.e., channel 3, Input 1, HDMI, etc.)?
- Are you using the proper connectors and color coding?
- Check the Set-top Box:
- Is the power on?
- Is the proper input selected?
