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.

Reset the HDMI cable.

A bad HDMI cable can sometimes cause your TV’s No Signal message to appear.

• A broken HDMI cable can prevent your TV from receiving signals even if the cable box has been turned on.
• Only a replacement can fix a cable that’s not working.
• You can test your HDMI cable by connecting it to another device such as a Blu-ray or DVD player.
• A new cable must be purchased if the cable is causing problems. Make sure the cable that you purchase is authentic and from a trusted seller.

2. Start the Cable Box and Television

The easiest solution to “No Signal” is to restart the cable box. A cable box works in the same way as a computer. This can be fixed quickly and often solves other small issues.

• Remove your cable box from the wall outlet.
• Ideal is to wait 60 seconds.
• Connect the cable box back to the wall outlet.
• Turn on the cable box to check for a signal.
• You must disconnect the cable box from the circuit breaker if it is attached behind the wall.

HDCP is a high-bandwidth digital content protection. It is a standard cable protocol that prohibits privacy in movies and TV programs.

You may experience any one of the following problems if your streaming device or cable is not HDCP-compliant: HDCP Error or Non-HDCP Output. Your TV will show “No Signal”, a gray or blank screen, or both.

5. Verify that the TV Box is On

The “No Signal” message on your screen can also indicate a power supply problem. Verify that your TV or cable box is turned on.

• A “No Signal” message will be displayed on your screen in such a situation.

6. Verify the TV Antena Signal

• After turning on the TV, press the Source button.
• Select the input method you prefer.
• To connect to the television, most cable boxes will use HDMI 1 and 2.

You can change the input source by using your remote.

• After turning on your TV, press the MENU button at the bottom or side of it.
• Use the volume button to access the source option.
