HDMI is an essential component in any entertainment system. It’s the standard connection cable used by Samsung TVs, video projectors, and gaming consoles.
If you connect an external media player like a set-top box, Xbox, desktop computer, or PlayStation, it should show up on your Samsung TV.
If it doesn’t, or if there is a red power icon on the Samsung TV HDMI port, an error message will appear such as “No signal”. If this happens, the HDMI ports need to be fixed.
A Samsung TV will not recognize an HDMI cable if it is damaged or if your input resolution is not compatible with your Samsung TV’s requirements.
You can pinpoint the
problem by switching your HDMI cable or connecting to another device.
There are many other things to take into consideration. For a deeper understanding of the issue and a comprehensive troubleshooting guide, read on.
Why Samsung TV HDMI ports do not work
These are some of the reasons why your Samsung TV’s HDMI ports don’t work:
You have connected your TV to an input that does not have any devices. The source is not able to supply power or is offline. The HDMI cable is loose at both ends. Your source resolution is not the same as that on your Samsung TV. A damaged HDMI cable is being used.
Another reason you may not be receiving an HDMI signal on your Samsung TV is the turn-on sequence.
These are some troubleshooting tips for fixing the “HDMI no Signal” error on Samsung TV.
Verify that the device is powered on
Samsung TVs made after 2017 should automatically detect devices once they are connected via HDMI. However, this cannot occur if the device’s power is not on.
Turn off the external device. Give it about ten seconds. Turn it on again.
To test the solution, you can use your TV.
Choose the right input source for your TV
Connecting an external device to your Samsung television is as easy as setting the source port on the TV to the same port that you connected the device.
Also, connect your gaming console to HDMI 1 port and then connect the source to HDMI 1.
It could be that the HDMI ports have been mixed up if the TV does not show any signal after being plugged in.
Connect the HDMI cable
You may have accidentally disconnected the HDMI cable or it might have become loose. It is worth disconnecting the HDMI cable from your TV’s back and connecting it to your source.
If your Samsung TV is not detecting HDMI from your PC, you can also do the same.
Connect the HDMI cable securely to the external device or the PC. Next, connect it with your TV.
If this fails, connect the cable to another port.
You will need to choose the source for your new TV, as described in step 2.
Use a different HDMI cable
You may be using an incorrect cable for your TV. A damaged HDMI cable can also prevent you from connecting.
You can connect your Xbox, PlayStation, or Roku to the Samsung TV with a different HDMI cable.
Consider replacing the cable if the problem persists. I recommend the iVanky high-speed braided cable because it is suitable for streaming HD content without lagging and it is braided meaning that there are minimal chances of damage.
You can change the order you turn your devices on and off
Try to alter the sequence of turning on the TV and external devices first. Also, make sure to turn on your Samsung TV first and then the external devices.
Consider using this order if it works.
Turn on the external device
You can power-cycle an external or input source to refresh its parameters and make it start again.
Unplug the device completely from the wall outlet or power strip. Give it about 60 seconds. Input the source input again.
Restart the TV and turn it on again. You can also power-cycle your TV using the steps above. This will allow you to reset your TV.
Software updates are available
Update the software that controls your inputs to resolve HDMI handshake problems. If your Samsung TV loses HDMI signal, this is a must-do step. If your Samsung TV keeps losing HDMI signal, you can do the following:
Go to Settings. Choose Support Choose Software Update Click Update Now.
The option can be turned ON to allow it to update automatically.
Go to Settings. Choose Support Choose Software Update Highlight Auto Update. Turn ON the option.
The TV will automatically update. After the update is complete, connect your external input to test it.
Understand that although updating your Samsung TV software is essential, many users have come across the problem after upgrading their firmware.
For further assistance, contact your TV manufacturer.
Factory reset your Samsung TV
You can reset the factory settings to allow you to begin again. This will erase all settings and you will need to reset HDMI inputs again. Here’s how it works:
Open Settings. Select General Select Reset. Enter your PIN, or 0000. Select Reset. To complete the reset, select OK
You can also go to Settings > Support > Self-Diagnosis > Reset.
Connect a different external device
This troubleshooting step aims to identify whether the problem is with your TV or the original device. Try connecting your computer instead of your set-top box.
If your PC is not working, there may be a problem with your set-top box. For assistance, contact the manufacturer. If both the manufacturer and the TV still show the error, it is time to service the TV.
Visit the Samsung support center to request repair service.
If you have an external device that you want to connect to your Samsung TV, but it won’t switch over to HDMI, you can try troubleshooting the problem to resolve the issue. First, ensure that you have chosen the correct input source.
Make sure the HDMI cable is
secure at both ends. Alternate cords or reverse the sequence to turn on your inputs are options.
