Since the update, my Sling TV no longer works. I use model 4660X2, it will load to Slings home screen very slowly but will not load any channels. I can load Sling TV fine on my one smart TV so this appears to be a Roku issue with the new update!

Why Is Sling TV Not Working?

The most common reasons for Sling TV not working are listed below:

  • Broken app: If the app is broken, your Sling TV may stop working.
  • Temporary failure: A temporary failure on the device can cause Sling TV to stop working properly.
  • Slow Internet: If your Sling TV won’t load, a slow internet connection could be the culprit.
  • Problems with Slings Server: If there is a problem with the Sling Server, then you may face issues with Slings TV not working properly.

Well, how to fix Sling TV not working? You can try the following methods.

Before solving the Sling TV not working issue, please check the Server Status of Sling TV.

Solution 1: Restart the Sling TV App

When the Sling TV not working issue occurs, you should identify what components cause the issue. The first thing you should do is restart Sling TV after closing the app completely. You can completely close the sling tv app and restart it by following the steps below.

  • Amazon Fire: Go to Settings > Apps > Manage Installed Apps. Then select Sling and force stopping Sling TV Now. Then fire up Sling TV on your fire stick.
  • Smartphones: Close the Sling TV app completely and restart your device. After restarting your smartphone, open the Sling TV app on your device.
  • Roku: Press Home on your Roku remote to close the Sling TV app. Then restart the Sling TV app.
  • Samsung TV: Press and hold the back button on the Samsung remote until you get to the Home Then launch the Sling TV app again.

Solution 2: Check your Wi-Fi and Internet Connection

The second thing you should do is check your internet connection, especially if you are using Wi-Fi. For Roku devices, go to Settings > Network Connection and make sure the internet is getting data.

If your device cannot connect to the internet, then there is a problem with your router or your device’s Wi-Fi settings. Therefore, you need to restart the router to fix internet problems.


Remember that your Wi-Fi router should be powerful enough to sustain the bandwidth required by Sling TV.

If you connect the internet and Sling TV still keeps loading or constantly buffering, you need to check the internet speed on your streaming device. For example, on Roku, you can check the speed of the stream by going to Sling TV’s Settings > Connection. If your streaming speed is below 1.0 Mbps, there is a problem with your device’s Wi-Fi connection, or your router is not fast enough.

If you have a dual-band router that supports 2.4GHz and 5GHz Wi-Fi bands, you can also try switching Wi-Fi channels. So, try switching the Wi-Fi band from your router settings.

Solution 5: Update the TV Firmware

Sometimes outdated device firmware can cause a lot of problems such as compatibility issues that lead to the Sling TV app crashing or lagging on the device. Updating your device can help if it hasn’t been updated for a long time. Here takes the Roku TV as an example.

If your TV is able to connect to the Internet, you can update the Roku TV firmware through the following steps:

  1. Press the Home button on your Roku remote.
  2. Go to Settings > System > System update.
  3. Select Check Now to manually check for updates.
  4. If new software is available or updates are available for your channel, your Roku device will automatically download and install them, and once done, your Roku device will reboot.

If your TV is not able to connect to the Internet, you need to update the TV firmware via a USB drive. Here is the guide:


If you are trying to install a Samsung TV software update, you can refer to this article.

Step 1: Open a web browser and visit this site. Then choose the mode of your Roku TV (e.g., TCL)

Step 2: Enter your Roku Model Number and Serial Number. The model number is displayed as 4 numbers followed by a letter (e.g., 6104X) and the serial number is a combination of 12 numbers and/or letters. To find this information, go to Settings > System > About on your Roku TV.

Step 3: Select Download Software to get the update.roku installer file downloaded to your computer. Then locate the update.roku file on your computer. By default, it is often in a Downloads folder.


If it is not in the downloads folder, it means that the user has changed the path stored in the browser, you can go to the browser settings to find it.

Step 4: Prepare a USB flash drive and format it to FAT. In general, the file system is FAT32. If the USB flash drive is larger than 2GB, choose FAT32. If it is less than 2GB, choose FAT16. You can do that using Windows File Explorer.


Sometimes, the USB flash drive may be larger than 32GB and you can’t format it to FAT32 using Windows built-in utilities. However, MiniTool Partition Wizard can help you do that. It can format a USB flash drive up to 2TB to FAT32.

Step 6: Press the Home button on your Roku remote and select Settings > System > System Updates > I can’t connect. Your Roku TV will verify the files on the USB flash drive and display the 12-digit code.


If you see an error message stating that the contents of the update file are invalid, your Roku TV is already running the latest version of the software.

Step 7: Get the 12-digit code and enter it into the appropriate text field on your computer. If the code you entered is correct, a 6-digit code will be displayed.

Step 8: Take this code to your Roku TV and enter it using the remote. Your Roku TV will begin the software update immediately and reboot when complete. After your Roku TV restarts, you can remove the USB flash drive.
