The ‘no signal’ message on your TV can be frustrating, especially when you want to enjoy your favourite show or movie. This issue can occur due to various reasons, ranging from loose cable connections to problems with your TV’s settings. Let’s look at three effective ways to troubleshoot the ‘no signal’ message to get your TV back up and running.
1. Check your cable connections
One of the most common causes of the ‘no signal’ message is a loose or damaged cable connection. Start by checking all the cables connected to your TV, including the power cable, HDMI cable, and any other input cables.
Ensure they are securely plugged in and free from any visible damage. If you suspect a faulty cable, try replacing it with a new one to see whether this resolves the issue.

Update your TV’s firmware
In some cases, outdated or glitchy TV firmware can cause the ‘no signal’ message to appear. Firmware is the software that controls your TV’s functions, and manufacturers often release updates to fix bugs and improve performance.
To check for firmware updates, consult your TV’s user manual or visit the manufacturer’s website. You may need to connect your TV to the internet to download and install the latest firmware.
3. Verify your input source
Another common reason for the ‘no signal’ message is an incorrect input source setting on your TV. Most TVs have multiple input sources, such as HDMI, AV, and USB, and you need to ensure the correct source is selected for the device you are trying to use.
According to Sony, you should use the ‘source’ or ‘input’ button on your TV remote to check your TV’s input source and cycle through the available options.
Make sure the selected source matches the input port to which your device is connected; for example, if your cable box is connected to HDMI 1, ensure the TV is set to the HDMI 1 input source.
