One way to troubleshoot digital television reception problems is to check the strength of your TV signal. Most digital television sets or set-top boxes have a basic signal strength display, and you can access this through the "system" or "setup" menu of your receiver. The signal strength is usually displayed as a percentage or a number on a scale from 1 to 10. Some receivers use traffic light colours with red for a weak, or nonexistent, signal and green for a strong signal. You will need a strong signal to enjoy stable, clear reception of all available digital TV and radio channels.
