Samsung TV Turns Off Itself And Won’t Turn Back On [Solved]

It is no secret that like many other types of electronic equipment, Samsung televisions have some shortcomings. 

This brand is widely accepted because of its breakthrough display technology and other smart features.

For example, one common problem Samsung TV users encounter is when the power button turns off the TV and it refuses to be turned on again. 

When this happens, it can be especially annoying, especially when anticipating your favorite shows or matches. 

Then, do you know that others have experienced this same issue?

In this article, we will explain the various features of this problem, and its reasons one by one, and suggest alternative solutions. 

By the end of this guide, you will have a good knowledge of the problem and a presentation of the solution that will target the particular problem effectively.

Understanding the Problem: Why Does My Samsung TV Turn Off by Itself?

However, before looking for the cause of the issue, let us first outline some reasons why the television set automatically switches off. 

Several explanations may exist, and understanding the source will help you assess which specialized troubleshooting methods to use.

1. Power Supply Issues

A defective power supply unit (PSU) is one of the factors that could make a Samsung television turn itself off at random times. 

The television may switch off due to a surge or fluctuation in the power line, or because one of the reasons such as the power board that powers the TV most times is faulty.

Power Surge: 

These can cause the television to switch off if the power board is affected by surges or the area experiences frequent outages. 

An internal circuitry may perceive a disturbance in the power supply and switch the TV off automatically as a protection measure.

Power Supply Board Malfunction:  

Standing the test of time, a power supply board must sometimes retire and go rest with the good old ones. Unfortunately, it leaves the TVs with chronically poor functioning power delivery.

2. IssuesOverheating 

No question, creating energy-saving devices is one of the primary aims of Samsung Has it’s depth, however, and while the unit is running, it does release a certain amount of heat. 

If your television is not ventilated properly or a poorly ventilated space is where the TV is located, then the unit is bound to sustain heat damage that may cause it to shut off.

Blocked Vents: 

The area around the television should not be too tiny for air circulation as this increases the risk of overheating. If vents are blocked, this can lead to overheating.

Internal Dust Accumulation:  

Even inside dust can be a problem as it is present in an uncontrolled area inside the TV. 

Let alone the case of the TV unit shutting down when needed to protect its units, this may also be a source of even more difficulties.

3. Faulty HDMI Devices or Connections

The external devices that have been connected to the Samsung TV through HDMI such as gaming consoles, Blu-ray players, or sound bars may cause the problem. 

It is also possible that some HDMI devices/connections are faulty thus causing the TV to switch off sometimes.

HDMI CEC Settings: 

Samsung TVs are typically installed with HDMI CEC functionality that enables connected HDMI devices to control the TV. 

If this feature does not work properly, or there’s something wrong with other devices, then it is very possible that the TV will get turned off.

Faulty HDMI Cable or Port: 

Another reason for the TV shutting off could be, a Broken HDMI Cable or an HDMI Port.

4. Software or Firmware Glitches

Samsung TV, like other smart devices, has operating software that should provide the basic functions of the appliance. 

Damage to the firmware of the television set or its obsolescence causes some troubles, one of which is the ability of the television to continue working and switching on independently.

Outdated Firmware: 

If the firmware of your TV is outdated, then this will also be a primary cause for the unstable performance of the system. 

Most of the newer versions of the firmware will be able to enhance performance due to bugs being resolved.

Software Glitches:  

The other software sometimes can also be the reason behind this issue, whereby the tv turns off when it’s not supposed to turn off. 

This could take place after a software upgrade has been unsuccessful or after employing third-party applications.

5. Remote Control Malfunctions

Samsung’s television remote control is also capable of functioning incorrectly. 

For example, have you ever seen that the remote control has fallen into a couch cushion? As a result, it is ‘pushed’ deep into the Xang dump from which it is unlikely to be retrieved again. 

In this case, the television can also switch off by itself because of a power button being stuck.

Interference from Other Remote Controls: 

If there are other remote devices in the vicinity, the signals might get crossed, resulting in the TV being turned off unintentionally.

6. TV Settings and Timers

There is also a possibility that you left a sleep timer on, which would be similar to an energy-save mode feature on Samsung TVs that switches the device off after too much time without use.

Auto Power-Off or Sleep Timer:  

This type of concept is useful in most cases, however not when the timer or the concept of the auto power off is set by mistake or without even having the user remember it was set in the first place.

How to troubleshoot your Samsung television set: Solutions of this type in sequential order

Now that we have a good gauge of what could be the reason for your Samsung TV, let’s focus on some practical measures and other steps you can take to help the smart system working on the TV get the device working as normal.

Step 1: Check the Power Supply

Same as above, in the vast majority of cases, the reason a Samsung TV keeps turning off is due to a power supply issue. This is how you’re able to check it done:

Power Surge Protection: 

If for instance the TV is plugged in a power strip or surge protector, make sure it is working so that there does not arise any more interruptions coming from such devices. 

These devices do sometimes seem to wear off causing interruptions in power supply. 

It may help to remove the power strip and see whether the TV works when plugged straight into the wall.

Inspect the Power Cable: 

Examine the power cable for any cracks or damaged ends. Sometimes, a frayed cable can cause a power break which leads to a situation when the TV doesn’t operate correctly. 

If the inspection reveals wear and tear, then swapping this with a new one should resolve the issue.

Check the Wall Outlet: 

Try plugging in an additional appliance like a light or cell phone charger and observe if the outlet is working. 

If the outlet appears to be faulty, it could be the reason for the TV’s disconnection as it is unable to supply the required power.

Reset the TV:

Turn the TV off, remove the power cable from the wall, and wait thirty seconds before powering the TV on again. 

This action can assist in shutting down some internal systems and resolving certain low-level electricity-related problems.

Step 2: Prevent Overheating

To avoid excessive heating factors in the television, the following guidelines should be observed:

Ensure Proper Ventilation: 

Make Sure There Is Adequate Space: 

Make sure there is enough room available all around the TV for ventilation. Make sure that the TV is not placed in a confined cupboard or too many inches from the wall. 

A small addition is to say that when possible, at least 2-3 inches should be present on the outside of the TV on every side.

Clean Dust from Vents: 

Excessive dust within the confines of the television set can obstruct the proper flow of air and overheating issues may develop. 

With a soft brush or compressed air clean the holes and eliminate dust deposits. The television set should not be forcibly blown air into as this leads to internal parts getting damaged.

Cool Down the TV: 

Let your TV cool for around 10 to 15 minutes, in case there is too much heat which forms around it, and for some reason, you want to switch it on. 

Alternatively, a fan may also be used to facilitate cooling of the TV.

Step 3: Inspect External Devices and HDMI Connections

If your TV switches off when one or more devices are connected, then the problem is experienced with the HDMI ports or the connecting cables. 

Thus the following practices can help:

Unplug External Devices: 

Make sure all external devices (eg. Xbox, soundbars, or flicks in your case) are disconnected from the HDMI ports. 

After that, switch the TV off and back on again. If this device does not switch off, it means one of the devices plugged is the cause.

Check HDMI Cables: 

Vision cables may be damaged or have exposure through wrenching. Consider experimenting with a fresh cable to see if the grievances continue.

Disable HDMI-CEC: 

Steps followed include going to the settings of the television and disabling the HDMI-CEC feature. 

It lets connected items control the TV, which is often prone to conflict that turns the TV off.

Step 4: Update or Reinstall Software

For cases where the Samsung TV displays issues as a result of an outdated firmware, it is applicable to follow the

Check for Software Updates:  

Software Updates: 

Navigate to Settings > Support > Software Update and see if there is an option for updating the available firmware. 

If there is, make sure to update it as per the instructions provided on the screen.

Factory Reset the TV: 

If the issue persists even after updating the firmware, you should consider a factory reset. This would help rectify any software related issues that may be the cause. 

To reset your TV, navigate to Settings > Support > Self Diagnosis > Reset and follow the instructions provided.

Step 5: Inspect the Remote Control

It’s possible that you accidentally pressed a button on the remote control which makes it send a signal to the TV which makes it turn off by itself – this is worth noting:

Remove the Batteries: 

The first thing to do here would be to take the batteries off the remote. Then see if the TV turns off by itself. 

If it does not, then the mayo fault lies in the remote control which requires replacement.

Check for Interference: 

If you have other remotes with you, then remove them and check if the issue still occurs.

Check for Interference: 

Eventually, take a look at the configurations of your TV again and check whether it has an internal timer shut-off or energy-saving configuration which is the trigger behind the TV being switched off.

Step 6: Adjust TV Settings

Eventually, take a look at the configurations of your TV again and check whether it has an internal timer shut-off or energy-saving configuration which is the trigger behind the TV being switched off.

Turn Off Sleep Timer:

Turn Off Sleep Timer: In Settings, navigate to General > System Manager > Time > Sleep Timer and check whether this is the cause of concern.

Disable Auto Power-Off: 

Disable Auto Power-Off: Furthermore, go to Settings > General > Eco Solution > Auto Power Off and deactivate this option.
