If your Samsung TV fails to detect a specific or any wireless network, start by navigating to Settings > General > Network > Network Settings > Wireless.

Check to see whether your Wi-Fi network is displayed on your TV. If it isn’t mentioned, try to see if your network has been concealed by your television. Select Add, then type the network’s name.

Alternatively, you might attempt each of the following steps:

  • Restart or power-cycle your network equipment: Disconnect your router and modem from the power supply and your television. Reconnect them to the network by plugging them in again.
  • Reset your TV: Go to the Settings menu. > Support > Self Diagnosis > Reset and enter your PIN (the default is 0000). After the reset, try connecting again.
  • Check for software updates and install them if available: Go to the Settings menu. > Support > Software Update > Update Now.

If your TV cannot connect to the internet, perform a network status test. Go to the Settings menu. > General > Network > Network Status.

Run the test and keep an eye out for any error warnings. An error notice will instruct you on how to resolve the problem.

The cable box is not recognized by the Samsung TV.

When you attach the cable box to your Samsung TV, it should instantly identify it. If nothing occurs, use your remote to choose the cable box by pressing Source.

Alternatively, utilize the on-screen menu to go to the Source and choose the HDMI connection you used to connect your cable box. Check to see whether the cable box has been turned on.

If the HDMI ports aren’t working, you’ll have the same problem. Connect to a different HDMI port, reconnect the HDMI cable, or use a new cable.

On a Samsung Smart TV, apps will not install.

If you’re having trouble getting applications to install on your Samsung TV, try the following:

The remote control on my Samsung TV isn’t working.

One of the most prevalent Samsung Smart TV issues is this. We’ve even put out a comprehensive troubleshooting manual for it. You may attempt to solve this problem in a variety of ways:

  • Remove the batteries from the remote, press the Power button for eight seconds, then replace the batteries and try using it again.
  • Using a digital camera, see whether the remote transmits an IR signal. Press and hold the Power button on the remote while pointing it towards your phone camera. Look at the camera screen to check whether the remote is emitting a colorful light. This means that the item is in good functioning order.
  • Try again after cleaning the touch controls on the TV’s bezel.

You may also try replacing the batteries with fresh ones and restarting the process.

The Samsung TV will not come on, but a red light will continue to flicker.

If your Samsung TV does not switch on but the red light blinks, it signifies the surge protectors have worn out or the power supply is insufficient.

The protectors will not deliver the appropriate power for your TV in this instance. The best course of action is to see whether the protections are ineffective.

If not, it’s possible that your TV is having hardware difficulties that are beyond your control. The best course of action is to seek help from a Samsung Support Center near you.

The Samsung TV does not seem to be able to connect to a Samsung server.

Here’s what you should do if your Samsung TV isn’t connecting to the Samsung server:

  • Restart the TV and try again.
  • To check whether the device will connect, set up a connection using a mobile hotspot. If this is the case, the issue is with your router.
  • Check the network status of your TV by going to Settings > General > Network > Network Status and run the test.
  • Reset the network by navigating to Settings > General > Network > Reset Network. After the reset, try connecting again.

You might also try rebooting your network equipment, such as your modem and router. Use an Ethernet cable if you’re connected wirelessly. If you don’t already have one, we suggest DbillionDa’s sturdy cat8 Lan cable.

The images on my Samsung TV aren’t showing up.

  • Unplug the TV from the power outlet for 30 seconds before plugging it into a functional socket.

  • Perform a picture test by going to Settings > Support > Self Diagnosis > Picture Test. Follow the on-screen directions to fix the issue.

If you haven’t turned on the connected device, chosen the wrong source, or are using a broken connection, your Samsung TV may not detect the HDMI cable.

You may, however, troubleshoot this problem as follows:

  • Verify that the linked device is turned on by pressing the power button.
  • Set your TV’s source to the same port that you used to connect your device. If your gadget is connected through HDMI port 1, your TV’s source should be HDMI 1.
  • Disconnect and reattach the HDMI cable on both ends.
  • If it doesn’t work, try attaching the HDMI cable to a different port.
  • Check the HDMI port with a different device to see if it works. If it happens, contact the manufacturer or arrange a repair of the preceding item.

If your cable and external device are both operating properly, the problem is most likely with your TV or HDMI ports. In such situation, go to the Support Center and make a repair request.

Otherwise, you’ll need to replace the cable if it’s broken.

Samsung TV does not have any apps.

On a Samsung Smart TV, you can download applications and run them just as you would on a smartphone. However, the applications may have difficulties and cease operating or become unavailable on the Samsung smartphone.

Here’s how to troubleshoot the problem:

  • Unplug your modem, router, and TV to power cycle any connected devices. Remove the power cords from the wall, but don’t detach any Ethernet wires.
  • Reconnect your equipment one by one and wait for your television to connect.
  • Reconnect the TV and turn it on.

Try accessing the apps and see whether it has fixed the issue. If that does not work, check for Samsung TV software updates. Go to the Settings menu. > Support > Software Update, and then select Update Now.

Factory resetting your television is an extreme solution. However, this would need re-downloading and installing the programs.

The Smart Hub on Samsung TV isn’t working.

The Samsung Smart Hub is a feature that gives you access to all of your Smart TV’s apps. Resetting it is the best solution if it isn’t functioning. Here’s how to do it:

  • Go to the Settings menu.
  • Choose Support.
  • Self-Diagnosis is a good option.
  • Select Reset Smart Hub from the drop-down menu.

If you have a different model, Go to the Settings menu. > Support > Device Care > Self Diagnosis > Reset Smart Hub. You can find more information in this Smart Hub troubleshooting guide.

To access your apps after resetting Smart Hub, try accessing it again. If a password is required, use the default value of 0000.

A black screen appears on the Samsung TV.

Many consumers are concerned when they see a dark screen. However, if your TV is turned off, the screen may be black. You have an issue if you hear sound but don’t see any visuals.

It’s possible that your external device (such as a TV box or streaming media) is at blame, rather than the TV. In this situation, try an alternative external device to see if it resolves the issue.

You may also attempt the following troubleshooting steps to resolve the problem:

  • To test whether the menu shows, press the Home button on your remote. If you see a menu, your TV is operating properly but is not tuned to the right channel. It’s also possible that the gadget isn’t getting a signal.
  • If you don’t see the menu, your TV isn’t getting enough power.

Also, check to see whether your TV is set to the same source as your external device. Set the TV source to HDMI 1 if you have a cable box connected to HDMI 1 for example.

  • One cable at a time, unplug and reattach the AV connectors on both ends.
  • Any broken wires should be replaced.
  • After reconnecting, turn your TV off and on to check whether the problem has been resolved.

Another thing you may do is put your HDMI cable to the test. Here’s how to do it:

  • Ensure that your TV’s source is set to HDMI.
  • Go to the Settings menu. > Support > Self Diagnosis > Signal Information > HDMI Cable Test > Start Test.

If the test verifies that your cable is faulty, you’ll need to replace it. If you need a new cable, the PowerBear HDMI cable is a good choice.
