Facing TV Problems? Ask a TV Technician.
Hello, No Signal, or No Input either means the TV is set to the WRONG "Input", or it's LOST signal from the device you are trying to watch.
So that being said, if you are trying to watch a cable box on the TV, then first make sure you have changed to the correct INPUT (Input button on the SHARP remote) and if that does not work, then reboot your cable box by pulling it's power cord for 10 seconds and plugging it back in.
