1. Check All Cables and Connections
HDMI cables are now used to transmit audio and video television signal from cable boxes. A weaker or less reliable HDMI connection can cause your TV to display a “No signal” warning. Make sure that your cable is properly plugged into the correct port.
Signal loss can be the primary cause of No signal errors. Make sure to inspect each cable box’s connection to your TV.
- If your cable box uses HDMI, make sure that the ends of each connector are not bent or damaged.
- Purchase gold-plated HDMI cables such as the Belkin Ultra HD.
- Use a towel or an earbud to clean the ports.
- You should also check if the device supports 4K and high bitrate audio.
- If broken, all cables and wires should be replaced.
- This is also possible if you have a digital TV that keeps dropping the signal.
Modify Your HDMI Port
An HDMI port that is not working properly could result in a No Signal warning. Smart TVs have many HDMI ports so you can connect your cable box to them.
- Each port has a different number.
- You’ll also see a port called HDMI ARC. It isn’t recommended to use this port as it connects to your TV and a home theatre system.
- You can also test your ports by connecting your TV to a second device, such as a Blu Ray or DVD player.
