Why did Sling TV disappear from my Samsung Smart Hub?

Sling only supports Samsung Tizen TVs from 2016 or later. Older models are no longer supported. Use a Fire TV Stick 4K or Roku via HDMI as a workaround.

Sling loads but shows a black screen on Samsung — how do I fix it?

Hold the physical power button on the TV body until it fully reboots. This clears the video renderer completely. If it persists, clear the Sling cache via Settings > Support > Device Care > Manage Storage.

Should I reset Smart Hub to fix Sling?

Only as a last resort. Try clearing the Sling cache, updating the app, and updating TV firmware first. A Smart Hub reset removes all installed apps and requires reinstalling everything.

Sling TV was working fine on your Samsung Smart TV — and now it’s not. Black screen, crashing on launch, freezing mid-stream, or a message saying it can’t play. Samsung + Sling is one of the most-searched combinations for streaming issues. Here are the fixes, Samsung-specific first.

First: Is Your Samsung TV Compatible With Sling TV?

Sling TV only supports Samsung Smart TVs running Tizen OS from 2016 or later. Older Samsung models (pre-2016) are not supported and the Sling app will not be available in their Smart Hub. If your TV is a 2015 model or older and Sling has disappeared from the app store, you’ve hit the compatibility wall. The fix: plug in a Fire TV Stick 4K or Roku Streaming Stick+ into your Samsung’s HDMI port and run Sling through that device instead.

9 Fixes for Sling TV Not Working on Samsung Smart TV

Fix 1: Hard Reboot the Samsung TV

This is the most important fix on Samsung, and it’s different from pressing power on the remote. Hold the physical power button on the TV body itself until the TV shuts off and reboots. This performs a full hardware reset — the remote’s Off function only puts the TV in standby mode, which keeps the app in memory. A full reboot clears Sling’s cached state, the video renderer, and often fixes black screens and freezing that a remote-off/on won’t touch.

Fix 2: Force-Close Sling in the App Switcher

On Samsung Tizen, apps running in the background continue consuming memory. Press and hold the Back button on your Samsung remote until you reach the Home screen — this fully exits Sling. Then relaunch it from Smart Hub. Alternatively: press the Home button → navigate to the Recent Apps section → close Sling from there.

Fix 3: Clear the Sling TV App Cache on Samsung

A corrupted cache is the most common cause of Sling crashing or showing a black screen on Samsung. Navigate to: Settings → Support → Device Care → Manage Storage → Sling TV → View Details → Clear Cache. After clearing, relaunch Sling and sign back in if prompted.
