No Signal on TV HDMI: I Finally Fixed It After 4 Hours

No Signal on TV HDMI: I Finally Fixed It After 4 Hours

A few days back, like every day, I finished my shift and decided to play a game of FIFA with my friends. 

However, to my surprise, the screen suddenly went blank and there was a ‘no signal’ error on the screen. 

I rebooted my console and power cycled the system, but the issue ‘no signal’ error was still there. 

This was a rather frustrating issue since there was nothing apparently wrong with the HDMI lead or gaming console.

After hours of research and going through a range of online articles and guides, I finally found a solution to the issue. 

The ‘no signal’ error when using the TV HDMI feature can be fixed by switching of the input source. If this does not work, try updating the chipset driver by going to the TV settings and checking for available updates.

What causes the ‘No Signal on TV HDMI’ error?

The ‘no signal’ error when using the TV HDMI features signifies that the TV is not receiving any input from the selected source.

The issue can pop up without the existence of any serious error and can be solved easily as well.

In this article, I have explained a total of five fixes. 

Note that, they need to be applied one by one until one of the fixes ends up working.

Switch the Input Source

Sometimes, the problem may arise due to a faulty HDMI port. Change the HDMI port and switch the input source on the TV. This should resolve the problem.

To change the input source:

  • Press the Input or Source button on the remote.
  • Ensure to select the correct HDMI port if there is more than one.

Enable HDMI Connection Setting

A disabled HDMI connection setting can lead to the ‘no signal’ error.

Here’s how you can fix this:

  • Open the TV settings. 
  • Go to the “Display Entries” menu
  • Select the “HDMI Connection on your device” option
  • Now enable the HDMI connection setting 

Disconnect all HDMI sources

Moving on, another fix that has been known to work is simply disconnecting all HDMI devices and then reconnecting them again.

This includes the HDMI cable, all TV/monitors that are connected, as well as the other HDMI ports that are in use.

Update Chipset and Graphics Drivers

If the solutions mentioned above do not work, and you’re getting this while trying to connect the TV to your computer, there might be an issue with the chipset or graphic drivers

This can be fixed by updating the drivers for your computer. Here’s what you need to do. 

  • Open Control Panel on Windows
  • Go to “Device Manager”.
  • Under Display adapters, right click your graphics card.
  • Select Properties.
  • Go to the Driver tab.
  • Select Update drivers.
  • Install the updates and restart your computer. 

After the computer turns on, connect the TV to it and switch the TV to the HDMI input to see if the new drivers fixed the issue.

Performing a Factory Reset

If all the above methods fail, performing a factory reset on the TV, and the external device is recommended.

A range of minor glitches that might be contributing to the lack of signal can be fixed by performing a factory reset.

Note that performing a factory reset will erase all the data stored on the TV and uninstall all the apps you have downloaded. 

If the issue is not solved after applying each of the above-mentioned fixes, the problem might run with the HDMI cable, ports, or one of the devices in question.

Troubleshooting the “no signal” error on TV HDMI

In conclusion, if the above fixes are applied and do not yield a result, the problem runs a bit deeper and might require a replacement/repair.

Try using another HDMI cable. 

If that solves the problem, it means that the HDMI cable has been damaged.

To understand the device which is causing an issue, multiple steps can be taken.

If the signal problem is fixed when another HDMI port is used, it means that the HDMI port in question needs to be replaced.

Alternatively, if the issue is not coming up while using another TV, it means that the problem lies with the TV’s motherboard.

In this case, you will have to contact the manufacturer for probable repairs.
