6 Reasons Why Samsung TV Turns ON by Itself [SOLVED] – Let’s Fix It

Samsung is one of the leading brand in digital gadgets and Televisions, and it’s a fantastic product to have at home. But many users have claimed that their Samsung TV turns ON by itself without even touching it.

In the middle of the night, you wake up to the sound of your television. It’s so loud, you can hear it over your air conditioner or fan. What’s going on? It turns out that your Samsung Smart TV turned itself on for no reason and left you a little angry and frustrated. The cause: a simple problem, and it doesn’t need to be repaired.

Samsung TV Turns ON By Itself – Troubleshoot and Diagnosis

Your TV might turn on randomly for a couple of reasons. You might have set a timer to turn it on at a certain time, or the remote isn’t working properly, or your TV might be having software updates.

When your Samsung television unexpectedly turns on by itself, don’t freak out. In most cases, this is the result of a simple glitch that can be resolved in a matter of minutes. The first step is to check the power cord and sockets, because they’re commonly the cause of issues like this. The next thing to double-check is your TV remote control; make sure there are no batteries missing or that the transmitter on it is working.

Samsung TV Turns ON by Itself

1. Reconnect Power Cable

Samsung TVs are usually kept inside of cabinets. If you need to access the back of your TV, there may be a removable cover on the back of your TV. Carefully remove the cover with a screwdriver, and then carefully unplug the power supply cable (don’t pull it; use pliers).

First, check to make sure the power cable is firmly plugged in. If you’re sure it’s securely connected, try unplugging it, waiting a few seconds, and plugging it back in again. This can often re-establish power to the television.

This is a common solution for an older Samsung television model — you may want to test this with an older Samsung TV if you have access to one. Simply unplug the cable from the TV, reconnect it, and then plug it back in. If there are any visible cracks in the HDMI slot, it’s possible that your TV will work again after some repair work.

2. Disable Anynet+ (HDMI-CEC)

HDMI-CEC allows your HDMI devices to work together automatically and lets you use your TV remote to control some of your connected devices. It also gives HDMI devices limited control over your TV, letting you use the remote control for your TV to operate some of your connected devices. This can save frustration by helping you find and operate the right remote.

If you have a TV with HDMI-CEC, you can control your DVD player with the TV remote. Or, when you turn on your DVD player, your TV automatically switches to an HDMI input.

It’s often the case that you’ll want to prevent your HDMI device from turning on your TV as soon as you turn on your source device. In fact, it’s likely you want to do this with every HDMI device you own.

Samsung’s Anynet+ is a convenient feature that allows you to control many of your home entertainment devices like your TV and sound system wirelessly via one remote. However, if the TV turns on by itself or the screen goes black, it could be due to an issue with this feature. To fix it, go to the Settings menu > General > External Device Manager and turn off Anynet+.

NOTE: If you disable Anynet+, your TV will no longer accept commands from a connected remote control.

If it doesn’t work, make sure all of your devices are fully charged and restart them.

3. Disable Sleep Timer

The Sleep Timer is designed to automatically shut or start your TV off at the selected time. And while this feature can be convenient, it’s still best to turn it off if you’re concerned about energy efficiency.

To disable your sleep timer, locate the settings of your Samsung TV Remote control (or select ‘Home’ on your remote, and scroll left to find ‘Settings’). Scroll down to ‘General’, and then down to ‘System Manager’. From there you should see ‘Sleep Timer’ and ‘Off Timer’; click either of these options to display a submenu.

4. Disable SmartThings

The SmartThings app works with your Samsung TV to allow you to control multiple devices throughout your house no matter where you are. You can even turn on and off your lights, adjust the temperature in your home, or even lock your doors from your phone no matter where you are.

A popular smart TV feature is Samsung’s SmartThings, which is mentioned to be turned on by default. With this feature activated, your TV turns on when a nearby smart device does — like your thermostat, for example. However, Consumer Reports says this feature isn’t really necessary and may not be something you want enabled if you don’t regularly use it.

If you have a Samsung TV, it’s worth checking to ensure that its SmartThings is turned off. But if your TV is set up to automatically turn on with a connected phone, then all you need to do is disable that setting. The way to do this varies depending on the version of SmartThings installed on your phone — for example, Android or iOS.

To disable SmartThings, do the following:

  1. Click the Home button on the remote.
  2. Go to Settings.
  3. General > Network > Expert Settings > Power On with Mobile.
  4. Choose OFF option to disable it.

5. Upgrade the Firmware

As with any device, it’s important to keep your TV updated with the latest software. If you’re not sure what version of firmware your TV is running — or if you need help updating — there are a few ways to figure it out. First, go to your TV’s menu, find the system or settings tab, and look for the option labeled “system information” or something similar.

You can check which version of software your TV is running by going to your TV settings menu and then looking under the System tab. There will likely be three options: the most recent update, an older version, and a previous old version. If you see an old version there, it could be causing issues with daily use or entertainment on your TV.

In most cases, your TV will automatically update when you turn it on. However, sometimes the process fails and the screen doesn’t update. Make sure that you check to see if you have downloaded the latest version from the Samsung apps store on your TV. If this isn’t an option for you, try installing the TV’s current software version (which can be found in the settings).

6. Power-cycle your Samsung TV

Power-cycling your devices is an essential first step in troubleshooting. Whenever you experience an issue with an electronic device, power-cycle it to ensure that there aren’t any residual power issues.

You can do this by unplugging the TV from the wall, waiting 30 full seconds, and then plugging the TV back in while holding down the power button. This step helps to refresh your Samsung TV’s system and allows it to run more smoothly.

Power-cycling your Samsung TV can help to solve a wide range of issues that plague your device.

7. Disable Eco mode

Samsung TVs come with an Eco mode that, as the name suggests, is designed to help the device save power by automatically powering off various settings. In all likelihood, you don’t need these settings — and in fact, you may even be experiencing some issues as a result of them.

Turning off Eco mode on your Samsung TV is easy — just follow these steps: Select Settings on your remote control. Select General. Select Eco Solution. To turn off Eco Mode, disable Power Saving Mode, Eco Mode, and Motion Detection.
