Samsung smart TV Not Working: Common Issues
If your Samsung smart TV is not working, you can try several methods to fix it. The first step to Samsung TV troubleshooting is to figure out what is causing the problem.
1. App is not working on Samsung smart TV
Sometimes, apps on Samsung TVs stop working correctly. For example, while trying to open an app, it keeps crashing or doesn’t launch at all. In that case, you can try different methods to troubleshoot the issue.
First, try giving your TV a cold boot. A cold boot is similar to a restart, as it shuts down the device and reboots it. Usually, it solves issues with apps, pictures, menu glitches, etc.
You can perform a cold boot in two ways:
- With a remote: Press the Power button on the remote control till the TV turns off and on again.
- Without a remote: Unplug your TV from the power outlet and keep it unplugged for 30 seconds. Then, plug it in again and turn the TV on.
You can check for updates and firmware updates if cold booting the TV doesn’t work.
To check for an app update:
- Press the Smart Hub option and go to Featured.
- Find out the App you’re having issues with and then press and hold down the Enter option.
- In the Sub Menu, go to the Update Apps option.
- Select the App you want to update.
- Choose Update and wait for the download to complete.
If the app still doesn’t work, it may be that the TV’s firmware isn’t compatible. So, you need to update the firmware.
- Go to Settings> Support.
- Go to Software Update.
- Select the Update Now option.
- While checking for updates, the TV will download them automatically if any are available updates.
- After downloading, install the firmware updates.
- You should cold reboot your TV after installing the app or firmware update.
Consider uninstalling and reinstalling the app. You can fix the issues you’re experiencing with that application by doing this.
To reinstall an app on the Samsung TV:
- Press the Home button on the remote and select Apps.
- Next, go to the Settings option.
- Next, navigate to the app you need to reinstall.
- Select the Delete option.
- If the Delete option isn’t available, select the reinstall option.
- Press the Return button on your remote.
- Choose the Search icon.
- Type the name of the app you uninstalled and press enter.
- Select the app from the results page and choose Install.
- Launch the app after reinstalling and sign in using your login information.

2. Samsung TV only shows a black screen
Usually, Samsung TVs show a black screen because of a defective connection with a video device or a Set Top Box connected to the TV. You can try connecting with another device or using another Source port. Check the cable to see if it’s working, and replace it if necessary.
To check the HDMI cable:
- Set the TV source to the HDMI cable you need testing.
- Select Menu and go to Settings.
- Select Support> Self-Diagnosis> signal Information.
- Select the HDMI cable and start testing.
The issue can, however, be caused by the power supply if no devices are connected to your TV. If the damaged capacitor is bloated or leaking, you will know if you have a faulty one inside the TV. Professional repair is recommended if your capacitor is broken.
3. Samsung TV flickers when in use
You can use several methods to fix a flickering Samsung TV screen. A cold reboot will first relieve the TV from processing pressure and allow it to start from scratch. However, a damaged jumper in the TV power supply can cause flickering even after a cold reboot. You should then hire professionals for the repair.
4. Samsung TV has no sound
First, check whether the TV is on mute or the volume is down to 0. Then, press the Mute button on the remote on and off to confirm.
Make sure the cables and external sources are not damaged or unsecured. Next, check whether the TV is paired with a speaker or Bluetooth headset. Finally, go to the Audio settings and unpair it.
If there’s still no sound, consider doing a cold reboot.
- Go to the Settings menu.
- Select the Sound option.
- Select Reset, then click Yes to confirm.

5. Smart Hub does not display any apps
There might be an update for this app for your Samsung Smart Hub if it doesn’t show the app you’re looking for. If there are any updates, install them.
Try switching your TV to the original settings if your app is missing.
- Press the Smart Hub button on the remote. (For older models, press the Home or Menu button.)
- Once it loads, press the following buttons: Fast Forward, 2,8, 9, and Rewind.
- Under the Internet Service Location, choose the country you want to use.
- Select Agree to the terms and conditions.
- Select Update.
- The Smart Hub will now be updated and reset.
6. Samsung TV won’t connect to Wi-Fi
Sometimes smart TVs have trouble connecting to the Wi-Fi. Connecting via Ethernet is better and more stable, but it may be impractical in homes with a router far from the TV.
First, check if other devices connect to the Internet as well. Then, disconnect one device from the network and see if the TV connects to the Wi-Fi. If that happens, then it means the network was jammed.
You can try rebooting the Wi-Fi router and TV to clear out any glitches or bugs in the network. Then, after they’re rebooted, turn them on and try to connect to the Internet again. If the network is fully functional, yet the TV can’t connect, you should contact Samsung Customer Support.
