Many people have claimed that when they want to watch TV, it unexpectedly and constantly turns off and on.
This is sometimes referred to as inadvertent power cycling. We will walk you through the actions you may take to address the issue so you can resume watching your preferred movies as quickly as possible!
In this article, I will address your query, Why Does My Samsung TV Keep Turning Off? and How to Fix it easily?
Why Does My Samsung TV Keep Turning Off?
There are numerous common causes for a Samsung TV to turn off within a few seconds. Let’s begin with a few of the simpler fixes before moving on to ones that will need you to disassemble your television.
1. Issues with the Power Supply
Quite often, the solution is as simple as double-checking your power cable and socket. If there is insufficient electricity, your Samsung TV will not be allowed to stay on, resulting in abrupt turn-offs within 5 seconds.
If that’s the case, here are several solutions:
- Firstly, check the power cable for any power difficulties. If you discover that it has been damaged or degraded, you must replace it.
- If the issue persists, the following approach is to inspect the socket for power issues. Disconnect your television and plug it into a separate power socket.
- Plug another electrical appliance into the socket to determine if the outlet you’re attempting to use is operational.
A voltage breaker or extension connector might possibly be the source of the problem. Before changing your power cable, double-check these too.
Preferably, you should remove the surge guard and extension cables and simply plug the TV straight into the socket to see whether it solves the problem.
2. Check If Anynet+ (HDMI-CEC) is Enabled
HDMI Consumer Electronics Control (HDMI-CEC) is basically an HDMI function that improves the interoperability of your smart devices. It allows your HDMI-connected electronics to manage your television and your television to control those devices.
For instance, using HDMI-CEC, you might use your television remote to operate your DVD player. Whenever you switch on the DVD player, it might seamlessly switch the input on the television to HDMI.
In certain circumstances, HDMI connections are set to switch off the TV promptly when they are turned off. This functionality is called Anynet+ (also termed HDMI-CEC) by Samsung, and if your television is going off on its own, you must investigate it.
To Enable Anynet+ (HDMI-CEC) in Samsung TV, follow the steps below.
Step 1: Click on the Home Button on your Samsung Remote.
Step 2: Select Settings.
Step 3: In Settings, Select System.
Step 4: In System, Select Expert Settings.
Step 5: In Expert Settings, Scroll down and in Anynet+ (HDMI-CEC) and select On.

Check to see if turning off Anynet+ resolves your problem. If that doesn’t, there are numerous more likely causes for your Samsung TV to switch off every five seconds.
3. Your Samsung TV Is Overheating
Due to a major lack of sufficient airflow, your Samsung TV may potentially turn off by itself unexpectedly. Your television may overheat and glitch if there is insufficient circulation and airflow.
Here’s something you should do if this is the case:
- Unplug your television
- Employing a soft dry cloth, eliminate all dirt from the rear of your television

Press in and then lift up to take out this cable. This will interrupt the transmission that is shorting out the television, forcing the motherboard to reset automatically.

Particularly, the issue is frequently caused by failing capacitors on the motherboard. Capacitors may malfunction for a variety of causes, but the most common is an electrical surge across a thunderstorm.

Nevertheless, if you’re really daring, you may remove the back paneling of your television and inspect the motherboard for abnormal bulging capacitors. But i totally recommend you to consult a TV expert or go to the Samsung Authorized Service Center.
8. Disconnect Your Samsung TV From the Internet
Smartphones, smart home gadgets, as well as other televisions linked to the very same internet connection as the Samsung TV may interact with it.
These gadgets can switch on your television by transmitting orders to it. When you enable Screen Cast on a smartphone, for instance, your television will switch on immediately.
Certain items may be accidentally interfering with your television, which you can test by unplugging your television from the network and utilizing it for a time to see whether the problem persists.
