Samsung TV Flashing On And Off [Fixed Solution]

There are few things as annoying as a Samsung TV that won’t stop turning on and off on its own especially. 

When you have your popcorn ready and are all excited to watch your favorite movie or the latest episode of your series. 

This is a more widespread problem that can be caused by several factors including software issues, connection problems, or hardware failure. 

This sea of restless waves will be dispelled in this article as we will explore the possible reasons for this disturbing problem and how to fix it so that your TV works perfectly again.

Understanding the Problem: Why Is Your Samsung TV Flashing On and Off?

 

Software Bugs

The flashing problem can be usually attributed to the software glitches that come with any gadget. 

 

All smart TVs, including Samsung, have their operating systems which need to be kept up-to-date. 

 

However, even a software update may be paradoxical and create more problems by causing bugs which may put the device into a cycle of frequent on-off on-off states.

 

Power Supply Problems

What is a power supply? That is without a doubt one of the most crucial tv components for its functioning. 

Any problem with the power board, or the wires that would connect the TV, would lead to the device switching itself on and off as he would be glitching in between functions.

 

Problems with HDMI Connection

These problems can also be caused by issues with HDMI connections. When there are several devices connected to the TV, an HDMI cable. 

That is malfunctioning or an incorrect setting may cause the devices to not communicate properly, hence the TV keeps blinking on and off.

Overheating

Samsung TVs come with certain safeguards to avoid overheating. 

If your TV is in an enclosed area with bad airflow, it will most likely overheat and automatically shut down for its protection.

External Devices

In some cases, external devices like sound systems or gaming consoles that were connected to the TV can prevent it from working properly. 

When a device is not functioning properly, it may send the wrong signals to the TV, resulting in blinking lights and the screen turning on and off.

Defective Hardware

Hardware failures caused by defective components, for example, the main board or general failure of any of the capacitors located inside the TV can also be the cause of the problem.

 Most of the time, these need to be fixed by a technician.

Personal Anecdote

 

When I was watching a football match, my Samsung TV started turning on and off repeatedly. 

Initially, I thought it was a minor issue, but when the TV went off and on for the umpteenth time, I was no longer excited but rather annoyed.

I attempted every kind of way out, from simply switching it off and switching it on again to checking the HDMI connections, all to no avail. 

I did not come across this problem until later when I was looking for an answer to my problem by trying to resolve the problem. 

 

Only to discover the culprit which I had completely ignored: a loose power cable.

Step 1: Reboot the Samsung television first.

It helps because: 

There could be temporary glitches that interfere with normal operation; rebooting the smart TV helps get rid of them.

First, switch off the television. This can be done either with the TV power button or with a remote.

Next, unplug the Samsung television from the mains.

After this, let the television machine rest for a minute. This should allow all electricity to disperse from the television’s capacitors.

Then, turn the television machine on and check whether the problem persists.

Step 2: Check the power supply’s integrity

It helps because: 

There may be sporadic power supply issues if the power supply is faulty.

To begin with, double-check the power cord and ensure it is properly inserted into the TV and electrical outlets. Then, inspect the cables for visible damage.

Test Another Outlet: 

Simply connect the TV to another power outlet to check for a problem with the preceding plug.

Examine the Power Supply Unit: 

If you have that much confidence, open the back cover and search for bulged or leaking capacitors. 

If you happen to see any, the power supply board will probably have to be replaced.

Step 3: Check HDMI Connections

Why It Works: 

Faulty HDMI connections can lead the TV to interpret signals in the wrong way.

Moisten All HDMI Devices: 

Ensure that there is no device interface with the HDMI port.

Look Over the Cables: 

Check if any fraying or damage has occurred.

Reconnect Devices One at a Time: 

Connect the device back in switching the TV on each time, to determine whether the affected device was muted.

Change HDMI Ports: 

Change the ports in the TV to see whether the problem is still there or not.

An unusually hot TV should be switched off for some time.

Step 6: Reset the Device to Factory Setting

Go to the Menu Bar: 

This option may be found in the top right corner of the screen.
