If you’re hearing an echo, you probably have a separate sound system, like a soundbar or surround sound system and you have the volume playing both through your external sound system AND your TV speakers. You will want to go into the audio settings of your TV or cable box and adjust the “audio delay.” This should get you back in sync. It’s like watching a foreign film with a voice-over. You see someone’s mouth say “hello,” but then you hear “hello” after the mouth stops moving. There’s nothing more annoying than when you see someone’s mouth moving, but what you are hearing is not in sync.
If you have a picture on another device, then there is likely an issue with your signal or the box itself and you will need to contact your provider for service. If that still doesn’t resolve the issue, try switching to another device. If you’ve done that, you may need to reset your cable box by unplugging it and plugging it back in.
If you’re on the correct input and still don’t have a picture, make sure that your cable or satellite receiver is turned on and that all connections are secure. You can typically change the input by pushing a button on your TV remote labelled “input”, “source”, or “TV/Video.” Keep pushing the button to cycle through the inputs until you have your picture back. The most common reason is that your TV is on the wrong input. There are a number of possible causes for your TV turning on but not producing a picture.
