Short answer: most Fire TV Stick problems are fixed by restarting it (unplug for 60 seconds), checking the power adapter and HDMI port, updating the software, clearing app cache, or resetting the remote. Work through the steps below in order.
Quick checklist
- Unplug the Fire Stick from power for 60 seconds, then plug it back in.
- Use the original Amazon power adapter plugged into the wall, not the TV USB port.
- Try a different HDMI port, or use the HDMI extender that came in the box.
- Switch the TV to the correct HDMI input.
- Restart your router.
- Go to Settings → My Fire TV → About → Check for Updates.
- Clear the cache of the app that is not working.
- Restart the stick: Settings → My Fire TV → Restart.
- Replace the remote batteries and re-pair the remote.
- Check free storage: Settings → My Fire TV → About → Storage.
- Uninstall apps you no longer use.
- If nothing works, factory reset as a last resort.
Common Fire Stick problems
| Problem | Likely cause | Fix |
|---|---|---|
| Black screen / no signal | Wrong input, weak power, HDMI issue | Check input, use wall power, try another port |
| Stuck on Amazon logo | Software glitch | Unplug 60 seconds; if it repeats, factory reset |
| Remote not working | Batteries or pairing | See how to reset a Firestick remote |

Fire Stick keeps restarting
This is almost always a power problem. Use the official adapter and cable plugged into a wall socket. TV USB ports often do not supply enough power.
Fire Stick says “No internet connection”
- Restart the router and the stick.
- Forget the network and reconnect with the correct password.
- Move the router closer or use an HDMI extender to lift the stick from behind the TV.
- Check the date and time are correct.
When to factory reset
A factory reset erases apps and settings. Only do it after trying the steps above. See our step-by-step Firestick reset guide.
