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 for HD? (i.e., component, HDMI, DVI)
Confirm you are tuned to an HD channel, and verify the program you are watching is broadcasted in HD by visiting the program’s website.
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.
5. Still No Quality Picture?
Automated phone self help is available to help diagnose your cable TV problem, and send a signal to your cable box to fix the problem. If so, please Contact Us.
If phone self help does not resolve your cable TV problem, let the customer support representative know:
