HDMI No Signal Samsung TV? – Working Methods To Fix It

Samsung smart TV owners who have connected external HDMI devices (such as soundbars or gaming consoles) have probably encountered the “HDMI No Signal” error.

The “HDMI No Signal” error on Samsung TV can be frustrating at times, but it is typically very easy to fix. As it turns out, the most common solution may seem overly obvious, but believe me, it works in approximately 80% of cases.

The first step to resolving the HDMI No Signal error on your Samsung TV is to unplug it from the power source first. As a next step, it is necessary for you to continue holding the power button on your TV for a minimum of thirty seconds. By doing this, you will be able to drain any residual power and you will be able to hard reset your television. Do not plug your TV back in until you have waited another thirty seconds.

You should be able to fix the HDMI No Signal error as soon as your Samsung TV turns on again.


Power-cycle your Samsung TV and HDMI devices to Fix HDMI No Signal Error.

It’s usually recommended that you turn it off, then turn it back on again, which is what everyone says. However, there is a reason why this advice is so popular – it works!

A process that involves turning off, then turning on something again is known as “power-cycling”. Power-cycling your television is the first thing I want you to do.

You should disconnect the TV from the power outlet and take it off the wall as soon as you can. It is important to note that once you have unplugged the TV from the power outlet, keep pressing the power button for about thirty seconds.

Turning on the TV requires you to push the power button on the TV, rather than the power button on your remote.

You can use it to drain any residual power from your TV’s capacitors, resulting in a hard reset.

When the power button has been held for 30 seconds, release it.

The next step is to unplug the HDMI connected device and wait about sixty seconds. Plug your HDMI device into your TV and then plug your TV back in. You should no longer see the HDMI No Signal error when you turn your Samsung TV back on.


The input/source of your TV needs to be connected correctly.

Once you’ve powered-cycled your Samsung TV and HDMI-connected devices, make sure you’re using the right input/source.

Switching inputs is another “obvious” troubleshooting step. However, switching inputs often resolves the issue.

Let me know which HDMI port on your TV your device is connected to, so that I can assist you. This can be identified by gazing at the HDMI port number on your television.


This picture below shows the HDMI device connected to “HDMI #2 ”.

If you know which HDMI port your TV has, use your Samsung remote to press Input/Source and make sure it displays “HDMI 2 ”.

You should update the firmware or software on your TV.

If you don’t update your smart TV’s firmware/software, you might run into problems. You should check for new updates on your Samsung TV to ensure it has the up-to-date operating system.

Ensure Auto Update is enabled by going to Settings, clicking Support, then Software Update.

It is recommended that you select the “Update Now” option if there is one available.

From now on, your Samsung TV should be updated automatically. The process of installing a new update will likely take several minutes if there is one available.

Make sure you keep your Samsung TV updated with the latest software in the future. As a result, it will remain compatible with all HDMI-connected devices.


Set your Samsung TV back to factory settings by resetting it.

It’s worth trying a factory reset if you continue to get the HDMI No Signal message on Samsung TV.

You can restore your TV to its previous state by resetting it to factory defaults. You will lose all your apps, settings, and data as a result.

These straightforward instructions will guide you amidst the procedure of resetting your Samsung TV to factory settings.

  1. The Samsung remote should be set to Home.
  2. Go to the Settings page.
  3. Afterwards, select the general option.
  4. Lastly, select reset.

It’s under Settings, Support, Self Diagnosis, Reset on an older Samsung TV.

When requested to type a PIN, enter “0000” if you haven’t set a PIN. The Samsung TV will automatically turn off and then turn back on once you enter the PIN.

As soon as the setup screen appears, you’ll need to set up your TV just as you did when you bought it.


Try using another HDMI port if your HDMI port doesn’t work.

Alternatively, if the factory reset didn’t work, connect your HDMI device to another HDMI port on your Samsung TV.

Repeated use can lead to HDMI ports breaking over time, and eventually stopping working altogether. Simply switching ports will help you determine if this is causing your error.

Switch your TV’s HDMI input/source to the correct one after changing ports with your remote!


You need to change the HDMI device you are connecting.

If a new HDMI port doesn’t fix your HDMI device connection problem, you may have a problem with your Samsung TV.

Disconnect the HDMI device you’re trying to use, then connect a different HDMI device instead.

When connecting a gaming console, for example, disconnect it and connect your Blu-ray player instead.

When your Blu-ray player works, you know the problem is with your gaming console. If your Blu-ray player doesn’t work either, keep reading.


It is strongly encouraged that you swap out the HDMI cable with a new one.

Rather than go down the rabbit hole on this one, just know that your modern HDMI cable has more going on than you might imagine.

Quality demands have gone up in recent years thanks to 4K TVs, 60 frames-per-second, and Dolby Atmos audio.

In the past, things were simpler when compared to today. The HDMI cable failure rate was lower due to fewer demands and more tolerance for error. Unfortunately, that isn’t the case anymore.

You should first check if you have another HDMI cable lying around. It’s worth a shot to substitute it for your current cable if you have one. If the new cable does not work for you, you will probably have to buy a new one if it does not work for you.


Your new HDMI cable will have a lower chance of failing if you adhere to the following buying advice.

  1. When buying HDMI cables, make sure you buy them from a reputable retailer.
  2. Make sure your cable is between 1-2 meters long and not shorter or longer! Copper density is affected by cable length, and the sweet spot is between 1-2 meters.
  3. Ensure your HDMI cable can handle at least 48Gbps.
  4. Last but not least, purchase a mid-priced HDMI cable. A really cheap one is usually of poor quality, and an extremely expensive one is usually unnecessary.


HDMI No Signal Error On Samsung TV: A problem has been detected with the TV’s main logic board.

It’s likely you have a hardware issue if you’ve made it this far. If your TV has a problem with its main logic board, you probably have a hardware problem.

Logic boards, motherboards, main panels, and other terms are all used to describe the main logic board. Basically, it contains all the inputs and outputs for visuals and audio (including HDMI).


The “HDMI No Signal” error on a Samsung TV is caused by three common logic board problems.

  1. HDMI ports are broken.
  2. Below the HDMI ports, there are broken soldering pins.
  3. The IC (integrated circuit) seems to be having a problem (integrated circuit).

A bad IC chip can be identified by discoloration or burn marks. Due to the amount of soldering points holding these chips in place, they are difficult to replace.

Additionally, you need the right tools, which can be costly. It would be better to just buy a whole new main logic board if your IC chip is obviously bad.

Under the HDMI ports, on the underside of the main logic board, there might be broken soldering pins. Having loose or broken pins will prevent HDMI ports from working properly.


Finally, it is possible that the HDMI ports themselves are damaged. If you flash a light and look closely, you can find out.

The soldering connections holding the HDMI ports in place make replacing them very difficult. The board should probably be replaced entirely once again.
