7 Reasons Why Your Roku TV Keeps Turning Off by Itself (2023)

Roku TVs have some great features that allow them to stand out from the competition.

Thanks to Roku OS, you can have a smart TV that’s actually smart and has good software.

But what if your Roku TV keeps turning off without you pressing the power button?

Here are 7 reasons why your Roku TV keeps turning off by itself:

1. Your Roku TV is dead on arrival.
2. The power supply in your Roku TV is broken.
3. Your Roku TV is overheating.
4. A cable is causing the issue.
5. The firmware on your Roku TV is old.
6. An app on your Roku TV keeps crashing.
7. The Roku app on your phone is turning the TV off.

Read on to learn how to troubleshoot your Roku TV and how to stop the issue from happening again.

1. Your Roku TV Is Dead on Arrival

Unfortunately, most of us will experience that a product is DOA.

You see a new package on your porch, you get excited, you unbox the latest gadget, and it just won’t turn on.

When a piece of tech is dead on arrival, it doesn’t necessarily mean it won’t turn on, though.

In the case of your Roku TV, it could very well be that the TV was tested by the manufacturer.

TVs are expensive. So, it’s much easier for the manufacturer to test if it’s working from the get-go. However, they might’ve missed something.

If your Roku TV is brand-new and turns off by itself randomly, it’s probably DOA. If it happens after only a few seconds, then that’s a dead giveaway.

Of course, most new TVs have a decent warranty policy. You can return the TV and get a replacement or refund.

2. The Power Supply in Your Roku TV Is Broken

If you’re on the other side of the coin and your Roku TV is old, it might be a power supply issue.

TVs have a built-in power supply. It takes the electricity from your wall and steps it down into something that your display can use.

And the power supply is almost always the first to fail in an older TV.

If your Roku TV has problems turning on in addition to turning itself off, that could be a sign of a faulty power supply.

Unfortunately, fixing or replacing a TV power supply is difficult. It requires a lot of advanced knowledge of electronics.

Unless you know how to repair tech, it’s best to bring it to an electronics repair shop.

But only do this after you test everything else.

3. Your Roku TV Is Overheating

According to a study, 72% of Americans enjoy binge-watching TV shows regularly. If you’re one of us, you probably keep the TV on for hours at a time.

And even when you’re taking a break from the TV, you probably keep it on. You’ll be watching it again in a moment or two anyway.

However, this type of use is bad for the electronics inside your TV.

You can check whether your Roku TV is overheating by simply touching the back of the TV. Do this immediately after it turns off by itself.

If your Roku TV only turns off after you’ve been watching for a while, it’s probably because of overheating.

Some TVs will shut themselves down to prevent damage. But others will only shut down because the heat has already caused irreversible damage.

4. A Cable Is Causing the Issue

HDMI cables can be very finicky and cause some odd issues. Sometimes, these unnoticeable problems will cause the TV to turn off by itself.

Of course, the best way to troubleshoot an HDMI cable is to plug it out. If the TV stays on, then you know why it’s happening.

It could either be a problem with the HDMI cable or the device you plugged into your TV. Troubleshoot the cable first by using a different one.

If your Roku TV turns off again, then it has to do with the device you’re using.

If you have a regular TV with a Roku device plugged in, test the TV. Perhaps it’s Roku that’s causing the issue.

If the TV stays on, then some of the reasons below could explain it.

Also, there’s one other cable that comes out of your TV. And it’s the power cord.

You can usually tell that the cable is bad if the TV turns off when you wiggle it.

Thankfully, TV power cords are very easy and cheap to replace.

You can buy the Pwr+ TV 12 ft Power Cord on Amazon.com. It’s a 2-prong AC plug that works with Samsung, Sony, LG, TCL, and many other TV brands.

5. The Firmware on Your Roku TV Is Old

If you’ve been putting off the latest Roku TV update for the past few years, then this could be causing your problem.

Firmware, in general, can be very odd. Maybe your Roku TV worked fine for five years.

But all of a sudden, Roku dropped support, and your TV started turning off by itself.

It’s always a good idea to keep your software up to date on all your devices. Your Roku TV is no exception.

Maybe there was an important patch that you never installed. Or perhaps it was a major system update.

Whatever the case, updating the firmware on your Roku TV is very easy. Here’s what you have to do:

1. Go to the Home screen by pressing the Home button on your remote.
2. Open Settings.
3. Press on System.
4. Open System update.
5. Choose Check Now and allow your Roku TV to check if there’s a new update.
6. Allow the Roku TV to update automatically.

You can also see when the last update was. If you noticed that the TV has been turning off by itself since the update, then you know the cause of the problem.

For example, many users have reported issues with the 9.4 update.

Unfortunately, you can’t do much about this except wait for the next update.

6. An App on Your Roku TV Keeps Crashing

Sometimes, apps can cause weird issues with your Roku TV.

Even world-famous apps like Netflix and YouTube can act up and cause the TV to turn off every time they crash.

The problem can get so bad that you can’t even turn the TV on for more than a few seconds.

You can troubleshoot your apps by uninstalling them one by one until you find the one that’s causing the issue.

Also, I recommend trying to keep all the apps updated. If there’s a major issue with an app, most developers will hotfix it.

Your last resort would be to do a factory reset. Here’s how you do it:

1. Go to the Home screen by pressing the Home button on your remote.
2. Go to Settings.
3. Open System.
4. Open Advanced system settings.
5. Choose Factory reset everything, and complete the reset.

Also, your TV might have a hardware reset button on it.

Check the back and sides. You can use it instead of going through the menu.

That’s pretty handy if you can’t even keep the TV on.

7. The Roku App on Your Phone Is Turning the TV Off

Sometimes, the Roku app can cause some unusual issues as well. It can cause the TV to turn on or off by itself.

You can check if the app is at fault by temporarily uninstalling it. If the problem goes away, it was because of the app.

Don’t use it until Roku releases a new update.

By the way, keep the app updated at all times to reduce the chance of weird issues.
