If you are in the middle of watching your favorite program or trying to catch the big game, nothing would be more annoying than when your TV turns off by itself. Imagine if it started happening every five minutes.
Having a problem with your television that you cannot find an easy solution to can be infuriating. Calling in an expert or taking it to a repair shop can be expensive. Luckily, most problems that cause your TV to turn off by itself are fixed easily through some troubleshooting.
TV Keeps Turning Off? Here are Easy Fixes
There are many reasons that your TV keeps turning off every 5 seconds. It could be something physical like the power cord having a short or a faulty switch. But most problems are simple and may have something to do with your TV’s power settings.
1. Check the AC Cord Is Plugged in Properly
The AC cord to most appliances and electronics is designed not to come out unless pulled straight out. But the plug could slip a little if it gets plugged.
If anyone has been behind the TV lately to clean or to connect a new game system, they could have bumped it. If your Vizio TV keeps turning on and off by itself, look back there and be sure the cord is securely plugged into the outlet.
2. Ensure the AC Cord Isn’t Damaged
If your TV turns off by itself and won’t turn on, there could be something wrong with the cord. Cords can get damaged by vacuum cleaners, people stepping on them, or pets chewing on them. Look at the AC cord carefully, and be sure you do not see any signs of damage or fraying.
Be careful doing this, especially if the cord is plugged in. A cord with a short in it could be a shock or fire hazard. You may want to unplug it from the wall before you inspect it.
3. Test the Power Socket
If your Samsung TV turns off by itself, find another device you can plug into that socket and see if it works. If it does, you know that electricity is coming to that outlet and the problem is somewhere else. If it does not work, you will need to call an electrician.
4. Reset the TV
If your Samsung TV turns off by itself, you can reset it. Let the main menu load; you should see an option for settings. That will bring up the power settings option. You can reset the TV to go through a power cycle so that it turns off and comes on again. If the problem was a random power surge, this should fix it.
5. Inspect the Remote Control
Sometimes the solution to a problem is simple. Did someone sit on the remote? That could change the channel and make the TV turn on and off by itself. Even if that is not what happened, the remote could still be at fault.
It could also be a problem if you notice your TV turning on by itself. The power button may have become stuck and is constantly signaling the TV. Try taking the batteries out of it and see if the problem still happens.
6. Disable the Auto Power-Off
If your Samsung TV turns off by itself, it could be the setting that turns it off after a set amount of time. For example, if you do not change the channel or touch the volume control for a couple of hours, your TV will assume you have left or fallen asleep without turning it off. It will turn itself off to save electricity.
Your TV probably came with this setting turned on. If you are wondering how to stop your TV from turning off automatically, you can go into your power settings and set it to “off” easily enough.
7. Look at Your TV Timer
The TV timer is also known as the sleep timer. It is a failsafe that some people use when they watch TV at night while they lay in bed. It allows you to set a timer that will turn the TV off. Someone could have accidentally turned it on.
If you are asking, “why does my TV keep turning off by itself,” go into your power settings and be sure the sleep timer is deactivated. If it happens again, you will know that was not it.
8. Check Your CEC Settings
CEC stands for Consumer Electronics Control. That allows devices connected to your TV with an HDMI cable to be controlled using one remote. For example, turning on the device will cause the TV to turn on itself and automatically switch to the HDMI import the device is connected to.
This reason could be why your Fire TV turns off by itself. It may go off when the device is turned off. Try disconnecting your devices and see if the problem happens again.
9. Disconnect Your TV From Wi-Fi
Everything connects to the internet, and your TV is no different. You most likely have it connected to your home’s Wi-Fi so you can stream shows and movies without running an ethernet cable to it.
If the TV turns on by itself in the middle of the night, or if your TV is turning off by itself, it could be due to a faulty router or modem. It does not happen much, but it is a possibility. Try connecting your TV with a wired connection for a while and see if it happens again.
10. Clear the Cache
TV apps have a cache to keep your preferences in place, so you are not setting it up like new every time you turn it on. You do not want to put in your Netflix password every time, and the cache keeps that from happening.
But like other devices, when caches get full, it can make them act strange. So if your Roku TV keeps turning off by itself, go into your application manager and clear the cache on as many apps as possible. That could solve your problem.
11. Turn Off Eco Mode
Eco mode works a lot like your TV’s auto power-off. But the eco mode is designed to let your TV run in a lower power state with a dimmer picture and quieter sound. If your LG TV turned off by itself, the eco mode could have turned it off. If so, go into the power settings and disable it.
12. Check for Firmware Updates
Your smart TV has to install updates every so often, similar to how a computer updates. Go to your settings. Select “system” and then “about.” You should find the prompt to check for updates.
Updates are something that will take a while to do. So if your screen appears to freeze up and you cannot do anything with it, give it some time. But if your Samsung TV keeps turning off every 5 seconds, it could be a problem that the manufacturer fixed with a patch, and you just need an update.
13. Factory Reset the TV
Doing a factory reset should be the last resort, but if you cannot find the solution, you can reset the TV to its original state. If you go to the power settings, you will see the selection. Remember, this is making the TV forget everything since you bought it.
My TV Keeps Turning Off Every 5 Seconds
It could be any of the problems listed above, but the top culprit is the remote. There may be dust or debris caught in the power button and causing it to have a hair trigger. Try using a different remote or downloading a remote control app to your phone until you can buy a new one.
TV Turns Off Randomly
If your TV turns off randomly, it may be a power issue. There is a chance the AC cord is not plugged in properly or has a short in it. Try replugging it and checking for breaks or frayed places.
Why Does My TV Keep Restarting?
A smart TV, just like a phone or computer, can get viruses. So why does your smart TV turn off and on by itself repeatedly? You may have downloaded one. Try doing a factory reset on your TV. If the issue persists, contact the manufacturer.
Why Does My TV Turn On and Off Repeatedly?
If your TV continues turning on and off repeatedly, try unplugging it and plugging it back in. If you can get it to stay on long enough, go to your power settings and turn off everything you can. If you do that and follow all of the steps above, but it still doesn’t turn on, it is time to call the manufacturer.
If your TV turns off by itself, a few steps will usually remedy the problem and have you binging your favorite show quickly. However, if you use these tips and it still happens, call your manufacturer.
Frequently Asked Questions
The number one reason for this is the automatic shutoff, which can happen if you don’t interact with the remote or TV for a while. The TV probably thought you had left and turned itself off. You can turn this feature off in the device settings.
Some LG TVs have a removable power cord. If you checked the outlet and ensured you plugged it in correctly, you can check the connection to the TV. Be sure it is plugged all the way in. If it is, you may need a new cord.
Check for updates. It is easy to miss them or ignore a message to download them. But the updates have patches that fix problems with your electronics. If this is a problem LG knows about, there could be a patch to fix it. So download them and see if the problem continues.
