Roku TV Keeps Restarting – Meaning, Causes & Fix
A Roku TV that keeps restarting — cycling through the Roku boot logo repeatedly without reaching the home screen, or restarting unexpectedly during normal use — is one of the most frustrating Roku issues users encounter. This restart loop (also called a boot loop) can affect Roku-branded TVs (made by TCL, Hisense, and other manufacturers running Roku OS) as well as Roku streaming sticks and boxes connected to other TVs. The causes range from a corrupted software update, insufficient power supply, overheating, hardware failure, or a specific app or channel causing a crash loop. In the majority of cases, a Roku TV restart loop is software-related and is fully resolvable through a factory reset or firmware recovery without hardware replacement. This guide explains every cause and every fix step for a Roku TV or device that keeps restarting. For related TV fault issues, see our TCL TV Black Screen With Sound guide and our Samsung TV No Signal guide.
What it means
The Roku TV or device is unable to complete its startup or operating cycle, causing it to restart continuously. Usually caused by a corrupted software update, insufficient power, or a software crash loop.
Severity
HighCan you fix it yourself?
Yes — a factory reset or firmware recovery resolves most Roku restart loops.
Call a technician when
Contact Roku Support if the restart loop persists after a factory reset and the TV shows hardware-level faults.
What Does Keeps Restarting Mean?
Roku OS (the operating system running on Roku TVs and devices) is a lightweight Linux-based system. A restart loop occurs when the OS fails to reach a stable running state and the device's watchdog timer or crash recovery system forces a reboot, which then fails again in the same way.
Common causes of Roku TV restart loops:
1. Corrupted firmware update: A Roku OS update that failed partway through (due to power loss or network interruption) leaves the system in a broken state that causes boot failures. 2. Insufficient power supply: Roku sticks and some Roku TVs are sensitive to power supply quality. A failing TV power supply board or an underpowered USB port (for streaming sticks) causes repeated crash-reboots. 3. Overheating: Sustained overheating causes the processor to throttle and crash, triggering a reboot cycle. 4. Corrupted app or channel: A specific app that has become corrupted can crash the OS during startup if it is set to auto-launch. 5. Hardware failure: A failed storage chip (eMMC), RAM fault, or main board component failure causing persistent boot failures. 6. HDMI-CEC interference: For Roku streaming devices, HDMI-CEC signals from a connected TV can trigger unexpected reboots in some configurations.
This type of software crash loop is comparable to the HP Printer Blue Screen error on HP printers and the LG TV Red Light Blinking fault, both of which represent OS-level failures causing device lockout.
What Causes This Error?
- Corrupted Roku OS firmware update leaving the system unable to boot cleanly
- Insufficient or unstable power supply to the Roku TV or streaming device
- Overheating due to blocked ventilation causing thermal shutdown and reboot
- Corrupted channel or app set to auto-launch crashing the OS at startup
- Failed internal storage (eMMC) causing OS read errors and boot failure
- Hardware component failure on the main board
- HDMI-CEC signal from connected TV triggering unexpected Roku device reboots
- Electrical surge or power fluctuation corrupting OS storage
How to Fix Keeps Restarting
- 1
Perform a hard power cycle. Unplug the Roku TV (or Roku streaming device) from the power outlet completely. Wait 30 seconds. Plug back in. Watch whether the device completes the boot sequence past the Roku logo to the home screen. If it boots successfully, the restart was a one-time crash. Monitor for recurrence. For Roku sticks, ensure they are powered directly from the TV's USB port or a wall adapter — not a USB hub.

Attempt a factory reset using the physical reset button. If the device is stuck in a restart loop and cannot be accessed via the on-screen menu, use the physical reset button. On most Roku TVs, the reset button is a small recessed button on the back or side of the TV. Hold it for 20 seconds while the TV is powered on. The TV will reset to factory defaults. On Roku sticks, the reset button is on the side of the device. Note: this will erase all settings and require re-linking your Roku account.

Use Roku's recovery mode (if available). Some Roku TV models support a recovery mode accessible by holding the reset button while powering on. This triggers a clean OS reinstall from Roku's recovery partition. The exact button combination varies by model — consult the Roku support page for your model. Recovery mode reinstalls the firmware without erasing user data on some models.
- 4
Check for overheating. Ensure the Roku TV or device has adequate ventilation. For Roku sticks plugged into the back of a TV, use the HDMI extender cable included in the box to move the stick away from the TV's heat — sticks can overheat when plugged directly into the HDMI port flush against a warm TV back panel. For Roku TVs, ensure the ventilation slots are unobstructed.
- 5
For Roku sticks — check power supply. Roku sticks require a stable 5V/1A power supply. Underpowered USB ports cause instability and restart loops. Always power the Roku stick from the included wall adapter rather than the TV's USB port. If no wall adapter is available, use a quality 5V/2A USB charger.

Contact Roku for a remote factory reset. If the device is inaccessible due to the restart loop, log in to your Roku account at my.roku.com. Navigate to My Account > My Devices and select the affected device. Choose 'Remote Factory Reset' — this sends a factory reset command to the device the next time it connects to the internet, which can help if the device briefly connects during its boot attempts.
When to Call a Professional
A Roku TV that continues to restart loop after a factory reset and power supply check has a hardware failure — typically a failed eMMC storage chip or main board component. Contact Roku support at support.roku.com or 1-888-600-7658. For Roku-branded TVs made by TCL or Hisense, contact the TV manufacturer directly for warranty service. Main board replacement costs $100–$300 depending on TV size and model.
Can You Still Use the Device?
A Roku TV or device stuck in a restart loop cannot be used — it does not reach the home screen or any usable state. Do not leave the device plugged in and looping continuously for extended periods, as this generates unnecessary heat and may worsen a borderline hardware fault.
