Facing TV Problems? Ask a TV Technician.
Hello, If you're getting no signal when you try to watch TV (and have switched the Input), then it means that the Cable Box needs to be rebooted, or the HDMI cable between the box and TV has failed (since this is a digital connection and can dropout without warning.
If you have not already done this, please shut the TV off, then reboot the cable box by disconnecting it from power and plugging it back in. Check that the HDMI cable (if applicable) is connected securely on both ends and when the box reboots- turn the TV on and check the Input selections again.
Let me know what happens.
