Check the Power Cable and Outlet First
The most common reason a Firestick won't turn on is that it isn't getting power. Start by checking the cable that connects the Firestick to the power adapter—make sure it's plugged in firmly at both ends. The connection should click into place and sit flush against the device.
Next, test the outlet itself. Plug a lamp or phone charger into the same outlet to confirm it has power. If the outlet is dead, try a different one nearby. Some outlets are controlled by wall switches, so check whether a switch near the outlet is turned off. If you're using a power strip, make sure the strip itself is switched on and plugged into a working outlet.
Look at the power adapter—the brick-shaped device where the cable connects. It should have a small LED light on it. If the light is off or not visible, the adapter may have failed. Try a different power adapter if you have one available, or contact Amazon support for a replacement.
Key Takeaways
- A Firestick that won't turn on is usually not receiving power, so check the cable connection and test the outlet with another device first.
- The power adapter has a small LED light that should be on; if it's dark, the adapter itself may be broken.
- Unplugging the Firestick for 30 seconds and plugging it back in fixes many power and software problems.
- If the Firestick has power but no picture appears, the HDMI cable may be loose or the TV input may be set to the wrong source.
- Firesticks with a remote that has a power button may need a fresh battery in the remote before the device will respond.
Restart the Firestick with a Full Power Cycle
Once you've confirmed the outlet and cable are working, try a full power cycle. Unplug the power cable from the back of the Firestick itself—not just from the wall outlet. Wait 30 seconds, then plug it back in. This clears the device's memory and often fixes problems that prevent it from starting up.
Watch the LED light on the front of the Firestick. When you first plug it in, the light should turn on. It may be orange or white at first, then change color as the device boots. If the light never comes on, the power cable or adapter is still the problem.
The full boot process takes about two to three minutes. During this time, you may see the Amazon logo on your TV screen, or the screen may stay black. Do not unplug it again during this startup period. Once the home screen appears, the restart was successful.
Verify the HDMI Cable and TV Input
A Firestick that powers on but shows no picture on your TV is usually a cable or input problem, not a Firestick problem. Check the HDMI cable that runs from the Firestick to your TV. Unplug it from both ends and plug it back in firmly—the connector should slide in with a click and sit flush.
Inspect the HDMI cable itself for bent pins or visible damage. If the cable looks damaged, try a different HDMI cable if you have one. Some older or very cheap HDMI cables can fail, and a replacement costs $10 to $20.
Next, check your TV's input source. Use your TV remote to open the input menu—this is often labeled "Input," "Source," or "HDMI" on the remote. Select the HDMI port where your Firestick is plugged in. If you're not sure which port, try each one until the Firestick home screen appears. Once you find the right port, your TV should remember it the next time you turn on the Firestick.
Check the Remote Battery and Pairing
Firesticks with a remote that has a power button require the remote to be paired and have working batteries. If the remote's power button isn't turning on the Firestick, replace the batteries first. Most Firestick remotes use two AAA batteries. Open the battery compartment on the back of the remote and swap in fresh batteries.
If the Firestick still won't respond to the remote after a battery change, the remote may need to be re-paired. Hold down the Home button (the button with a house icon) on the remote for 10 seconds. The Firestick should recognize the remote and display a pairing message on the TV screen. If pairing fails, try holding the Home button for another 10 seconds.
Some Firestick models also have a physical power button on the device itself, usually on the back or side. If your Firestick has one, press it directly to turn the device on, even if the remote isn't working. This confirms whether the problem is the remote or the Firestick itself.
Look for Overheating or Physical Damage
Firesticks can shut down automatically if they overheat. Feel the back or sides of the device—if it's very hot to the touch, unplug it and let it cool for 15 to 20 minutes in a well-ventilated area. Do not cover the Firestick with blankets, place it in a closed cabinet, or set it on top of other electronics that generate heat.
Once it has cooled, plug it back in and try to turn it on. If it powers on and stays on, overheating was the problem. Going forward, make sure there's at least two inches of open space around the Firestick on all sides.
Inspect the Firestick for physical damage—cracks, dents, or water exposure. If the device has been dropped, sat on, or exposed to moisture, internal damage may prevent it from powering on. Physical damage is not covered by Amazon's standard warranty, though Amazon may offer a replacement at a discount.
Factory Reset as a Last Resort
If the Firestick powers on but is frozen or unresponsive, a factory reset can clear corrupted software. Locate the small reset button on the back or bottom of the Firestick—it's usually recessed so you need a paperclip or pin to press it. Hold the reset button down for 10 to 15 seconds while the device is powered on.
The Firestick will restart and show a setup screen, as if it were brand new. You'll need to sign in with your Amazon account again and reconnect to your Wi-Fi network. A factory reset erases all downloaded apps and settings, so use this only if the device is completely unresponsive and other steps haven't worked.
After a factory reset, the Firestick should boot normally. If it still won't turn on or respond, the hardware itself may be faulty and you should contact Amazon support for a replacement.
When to Contact Amazon Support
Contact Amazon support if you've tried all the steps above and the Firestick still won't turn on. Have the following information ready: the model number of your Firestick (found on the back of the device or in the original box), when you purchased it, and which troubleshooting steps you've already completed.
Amazon support can walk you through additional diagnostics over the phone or chat. If the device is still under warranty—usually one year from purchase—Amazon will often send a replacement at no cost. If the warranty has expired, Amazon may offer a discounted replacement or repair option.
You can reach Amazon support through the Amazon website, the Alexa app on your phone, or by calling the customer service number on your Amazon account. Response times vary, but chat support is often faster than phone support during peak hours.
Frequently Asked Questions
Why does my Firestick turn on but then turn off by itself?
This usually means the device is overheating or the power adapter is failing. Make sure the Firestick has open space around it and isn't in a hot location. If it keeps shutting down after cooling, the power adapter may not be delivering enough power—try a different adapter or contact Amazon for a replacement.
Can I use a different power adapter than the one that came with my Firestick?
Only if it has the exact same voltage and amperage rating printed on it. Using the wrong adapter can damage the Firestick or cause it to shut down unexpectedly. If you've lost your original adapter, buy a replacement from Amazon or a certified retailer rather than a generic one.
What if my Firestick is plugged into a TV with no separate power outlet nearby?
You can use a USB power adapter plugged into a wall outlet, or a powered USB hub. Some TVs have a USB port on the back that can power a Firestick, but this only works if the TV's USB port delivers enough power—check your TV's manual. A dedicated power adapter is more reliable than USB power.
Does a Firestick need to be connected to the internet to turn on?
No. A Firestick will power on and show the home screen without an internet connection. However, you won't be able to stream content until it connects to Wi-Fi. If the Firestick won't turn on at all, the problem is power or hardware, not the internet.
How long does a Firestick usually last before it stops working?
Most Firesticks last three to five years with normal use. If yours is older than that and won't turn on, the power adapter or internal components may have worn out. Newer Firestick models are more power-efficient and tend to last longer than older generations.
