HDMI cables are now used by cable boxes to transmit audio and video TV signals. A poor or insufficient HDMI connection may cause your TV to display the message “No Signal”. 

Make sure the cable is plugged in completely and in the right port. Examine the connections of each cable box to the TV because signal loss is the main cause of a No signal error.

  • If your cable box uses HDMI, make sure that neither of the connecting ends is twisted or otherwise compromised.
  • Buy gold-plated HDMI cables if necessary, such as the Belkin Ultra HD.
  • Examine the ports and clear out any possible dust or debris with a dry cloth or an earbud.
  • See if it also supports 4K and high bitrate audio.
  • All cables and wires, including the ones that power the set-top box and television, should be replaced if they are damaged.
