This second troubleshooting solution is an obvious answer to the HDMI no-signal Samsung TV issue. However, you should note that most users can overlook the simplest details on their Samsung TV and even forget to check its input source.
It can happen to anyone, so we highly recommend checking if the selected input source on your Samsung TV is correct before moving to other solutions. You can change the selected input source and switch to the correct one if incorrect.
You must also ensure the HDMI cable is plugged into your Samsung TV and the external input device. The Samsung TV screen will still display no signal even with the correct input source if the HDMI cable is loose or not connected yet.

3. Update the version of the TV’s software.
Software-related problems can cause all sorts of issues on your Samsung TV, which can also affect its connection with an external HDMI device. One way to resolve such issues is to update the version of your Samsung TV’s system software.
A software update not only fixes software-related problems but also improves your Samsung TV’s performance and compatibility with most apps, features, and devices. It can be the answer to your problem with the HDMI no-signal Samsung TV issue.
You can choose between two different methods to update your Samsung TV’s software version based on the reliability of your WiFi network. An over-the-air software update with fast and stable internet is feasible for Samsung TV users.
We recommend using the USB stick method instead for those connecting to a sluggish WiFi network. This manual method requires you to download the software update on a PC and transfer it to a USB stick.

4. Try connecting to another HDMI port.
Some Samsung TV models and external input devices have more than one HDMI port that you can use. If your Samsung TV and external input device are like that, we suggest using another one of their HDMI ports to see if that fixes the issue.
Believe it or not, your devices can just have a faulty HDMI port whether you use it often or not. Sometimes, the HDMI port on your Samsung TV or external input device might also have dust or dirt inside that could mess with the data transmission.
Whichever the case is, switching between HDMI ports can help you identify the ones that work and those that don’t. Once you’ve determined which HDMI ports aren’t working, you can blow air inside them to clear any dirt or dust buildup.
If all HDMI ports on the Samsung TV or external input device aren’t working, you must send them to a technician for repairs. Otherwise, you can move to the next solution to find another likely culprit to the HDMI no-signal Samsung TV issue.
5. Try connecting with another HDMI cable.
| Difficulty | Very Easy ●○○○○ |
| Number of Steps | 2 |
| Time to Perform Fix | 5 seconds |
| Things Needed | Spare or replacement HDMI cable |
Aside from the HDMI ports on your Samsung TV and external input device, the cable you’re using to connect both devices can also be the culprit. Oftentimes, the HDMI no-signal Samsung TV issue can be due to a faulty or damaged cable.
Before anything else, we recommend inspecting the HDMI cable you use for signs of wear and tear on its wires. You can also check inside its HDMI connector to see if there’s visible dust and dirt buildup or if it has any broken or missing connector pins.
If the HDMI cable only has dust or dirt inside its connector, you can simply blow air inside to remove them. Unfortunately, you’ll need to use another HDMI cable or purchase a new one if you don’t have a spare.
When plugging in the HDMI cable into the Samsung TV and external input device, you need to ensure it’s a snug fit. You can reseat the HDMI cable by unplugging and plugging it back in repeatedly until it fits well to avoid having a loose connection.
| Step 1: Unplug the HDMI cable from the Samsung TV and external input device. |
Step 2: Plug the HDMI cable back into the Samsung TV and external input device. Note: Check if the HDMI cable connector fits well into both devices’ ports. If the connector is loose, reseat the HDMI cable again until it’s secure and tight, or switch to another cable with a good connector. |
6. Check the connected HDMI device.

| Number of Steps | 1 |
| Time to Perform Fix | 30 to 60 seconds |
| Things Needed | PC or smartphoneWorking internet connection |
It’s also possible that the external input device you’re using is the root cause of the HDMI no-signal Samsung TV issue. We recommend inspecting your external input device for other errors that a simple restart sequence won’t be able to fix.
Like your Samsung TV, some external input devices might also have system software or firmware that needs to be updated.
HDMI devices like gaming consoles may require to be updated to the latest version before they can work well on your Samsung TV.
Depending on the external HDMI device you’re using, the update process will be different. We suggest reading the user manual with your device or looking up guides online to find out how to update its system software or firmware version.
You can also double-check if you turned on the external HDMI device because it’s easy to overlook this minor detail.
After all, no amount of troubleshooting your Samsung TV and reseating the HDMI cables will work if the device is turned off this whole time.
7. Perform a TV factory reset.

| Number of Steps | 8 |
| Time to Perform Fix | 5 minutes |
| Things Needed | Samsung TV remote control |
Our final suggestion is to perform a factory reset if none of the solutions above were able to resolve the HDMI no-signal Samsung TV issue. This method effectively deals with software-related problems that the software update cannot fix.
The factory reset will eliminate any virus or corrupt data file causing your Samsung TV to malfunction. After all, this reset will wipe the data saved on your Samsung TV, like its account data, installed apps, and system settings.
| WARNING: Save a copy of your personal data and TV preferences before doing a factory reset. If not, you could lose them, as the process will delete all of them per protocol. |
Wiping your Samsung TV’s saved data is the only downside of this method. Once done, expect your Samsung TV to work normally and for the HDMI connection issue to no longer occur unless the TV software wasn’t the culprit.
The factory reset will revert your Samsung TV to its default state. As such, you must set up the Smart Hub menu, sign in to your Samsung account, reinstall your apps, and reconfigure the system settings.
Step 1: Press your TV remote control’s home button and open the Samsung Smart Hub menu on display. |
Step 2: Scroll left/click the Settings tile on the Samsung Smart Hub menu. |
Step 3: Scroll down and click General on your TV’s system settings menu. |
Step 4: Scroll down and click Reset on your TV’s general settings menu. |
| Step 5: Enter the PIN passcode you’ve set on your Samsung TV and click Done to continue.  Note: IF you haven’t set any PIN passcode on your Samsung TV, use the default PIN (0000). |
Step 6: Select Yes and authorize the factory reset. |
| Step 7: Wait while your Samsung TV performs the factory reset sequence and reboots. |
Step 8: Set up the Samsung Smart Hub using the instructions on your TV display.  |
Problems With Your Samsung TV’s Main Board
Hardware issues on your Samsung TV’s main board can also mess up the HDMI connection with the external input device. Three notable components on the main board are likely culprits of the HDMI no-signal Samsung TV issue.
These are the main board’s IC chip, soldering pins, and the entire HDMI port itself.
Aside from the soldering pins below the main board, the IC chip and the HDMI port are difficult to replace due to the number of soldering pins securing them to the main board.
This means you should approach this solution with care. If you feel it’s not up to your abilities, don’t force yourself as you could end up making the problem worse than before.
We think that it would be easier just to replace the entire board. It’s also easier since you only need to unplug the ribbon cables and remove the screws on the main board.
To do so, you only need to screw the replacement board and plug in its ribbon cables. Not only is it the faster choice, but it’s also less prone to error.
Still, you need to be gentle when handling the motherboard. This can easily be the most expensive part of the Samsung TV.
There’s a catch, though. Replacing the TV motherboard would come out as a lot more expensive than repairing it.
As much as possible, you should deal with a Samsung-authorized service center if ever you want a professional to replace the motherboard. Getting a local repair expert might get you into hot waters as they’re not recognized by the brand.
