Samsung TV Keeps Restarting — How to Fix It

What Does This Error Mean?

Samsung TV keeps restarting is usually caused by a failed or interrupted firmware update that left the TV in a boot loop, or by an Eco Solution setting turning the TV off automatically. A 60-second cold boot resolves most software-related restart loops. A TV that restarts randomly during use — not just at startup — often has an overheating or power supply issue.

Affected Models

Samsung QLED
Samsung Crystal UHD
Samsung The Frame
Samsung Neo QLED
Most Samsung Smart TVs (2016+)

Common Causes

Firmware update was interrupted or failed, leaving the TV in a restart loop
Auto Power Off or Eco Solution is set to turn off the TV after a period of inactivity
Sleep Timer is enabled and running in the background
Power supply board is failing and cannot deliver stable voltage
TV is overheating and the thermal protection is triggering a restart
Software crash requiring a factory reset to resolve

How to Fix It

Unplug the TV from the wall for 60 seconds, then plug back in.

A cold boot clears any temporary software crash. If the TV reaches the home screen after this, a transient glitch caused the restart loop.
Disable Auto Power Off: Settings > General > System Manager > Time > Auto Power Off > Off.

Auto Power Off turns the TV off after 4 hours with no input signal. This is often mistaken for a restart loop.
Disable Sleep Timer: Settings > General > System Manager > Time > Sleep Timer > Off.

A Sleep Timer set to 30 or 60 minutes will turn off the TV on a predictable schedule — easy to overlook.
Check that the TV has clearance on all sides for airflow. Feel the back of the TV — excessive heat suggests overheating.

Samsung TVs need at least 4 inches of clearance behind and on the sides. An overheating TV may restart with no other warning.
If the TV is stuck in a boot loop and cannot reach Settings, try a factory reset: press and hold the TV power button for 15 seconds while it is plugged in.

The button reset method varies by model. On some models, holding the rear panel button initiates a reset sequence.

When to Call a Professional

If the TV restarts in a continuous loop and cannot reach the home screen, a technician can access recovery mode and reflash the firmware.

Frequently Asked Questions

My Samsung TV started restarting after a firmware update — what do I do?

A firmware update that was interrupted by a power cut or weak Wi-Fi can leave the TV in a restart loop. If a cold boot does not resolve it, connect a USB drive with the correct firmware file for your model (available from Samsung's support site) and use it to force a firmware recovery.

How do I factory reset a Samsung TV that is stuck in a boot loop?

If you cannot reach the Settings menu, try holding the physical power button on the TV for 10 to 15 seconds. Some Samsung models also enter a service menu via a button combination on the remote — check the Samsung support page for your specific model number.

Can overheating cause a Samsung TV to restart?

Yes. Samsung TVs have a thermal protection circuit that triggers a restart or shutdown when internal temperatures exceed safe limits. Ensure the TV has adequate ventilation and is not mounted flush against a wall or inside a closed cabinet.
