How to Troubleshoot a Samsung TV Input Source Problem

If your Samsung TV is not detecting an input source, the problem could be due to several reasons. Among them, a broken or damaged HDMI cable could cause a malfunction. In such a case, you can try connecting to another external device. This will fix the problem.


If your Samsung TV doesn’t recognize any of the HDMI input sources, you may need to update its software. Several reasons why a Samsung TV may not recognize an HDMI cable. These may include outdated firmware and software bugs. Also, it’s possible that the external device’s HDMI cable isn’t compatible with the TV. To fix this problem, follow these steps.

First, disconnect the HDMI cable. Generally, a broken HDMI cable is the cause of the problem. Reconnect the cable if the problem persists after powering off the source device. If it still doesn’t work, contact tech support.


Troubleshooting Samsung tv input-source problems starts with the device. If the TV is unable to recognize an HDMI input, there is a possibility that the device’s HDMI port has become faulty. To fix this issue, connect the device to the tv directly. Likewise, if the device is connected to an HDMI port but fails to show any signal, you can reconnect it using the other HDMI connection.

If you cannot connect an external device to the TV, try resetting the TV. Performing a soft reset will erase any temporary RAM that may have built up. This will also resolve any electronic glitches affecting the device’s performance or connectivity.


The input source may be faulty if you can’t see the video on your Samsung TV. You can try a power cycle to reset the device if this happens. If power cycling does not solve the problem, you may need to try to change the video output on your television.

The first step is ensuring the HDMI cable is properly plugged into the external device. The problem may be caused by a faulty HDMI port or a faulty HDMI cable. To resolve this issue, you should ensure that your Samsung TV’s input source is correctly connected to your external device. You can also try to reset the device by unplugging it from the HDMI port and then reconnecting it. Be sure to turn on the device when you have finished.

If you have a newer model of Samsung TV, you may have to change the system settings. Some of these changes can be quite simple. First, ensure that the HDMI cables are properly connected to the device and that the power cord is plugged into the TV power socket. Once you have done this, you’ll be ready to watch TV.


One of the first steps you need to take when your Samsung TV has an input source problem is to reset it. This can be done by turning on the TV and external device differently. This will solve the problem and return the TV to normal functioning. However, if the problem persists, you may have to purchase a new HDMI port, which costs between $200 and $300.

Next, you need to check the HDMI cable for damage. This is the most common cause of Samsung TV input source problems. Again, you can check it with a multimeter. If the wire flickers, it means it is damaged.

Checking the HDMI cable

If you’re experiencing trouble with the input source on your Samsung Smart TV, you may be experiencing a problem with your HDMI cable.

First, check if the HDMI cable is damaged. If the wire is damaged, it’s most likely that the Samsung TV doesn’t get enough power from the external device. If this is the case, you need to change the HDMI cable. Next, test the cable with a multimeter. If the multimeter flickers, you have a damaged wire.
