(SOLVED) How to Fix a Roku TV that Keeps Switching OFF?

Why do Roku TVs keep turning off?

The most common reason why a Roku TV turns off randomly because of a loose HDMI cable, insufficient power, a time limit has been set, or outdated software is installed.



  • Loose HDMI cable
  • TV getting insufficient power
  • Time limit reached
  • The software isn’t up to date


Loose HDMI cable

Loose cables- especially when it’s the HDMI cable- can send interrupted signals to your TV’s main board. Your TV can handle this most of the time, but when the interruptions are too frequent, your Roku TV will turn off on its own to save itself from any damage. In such cases, you should cable reset your TV immediately.


Insufficient power

Your TV needs the power to function properly. If it receives no or insufficient power, it won’t be able to function properly and will turn off by itself. So, if your TV turns off out of the blue, try checking whether your house is receiving a stable supply of electricity.


Time limit reached

All smart TVs come with the option to set viewing time limits. This helpful feature allows users to control their screen time and prevent them from wasting hours and hours on end watching TV.

With the time limit feature, you set the number of minutes or hours your TV can run each day. Once that limit is reached, your TV will turn off automatically.


Outdated software

If you’re running old software on your device and a newer version comes along, your device will update automatically. When the updates are complete, your TV usually needs a reboot to implement the changes. So, if your TV turns off automatically while you’re watching it, it could be because of this.

Roku TV keeps switching off


Why does Roku TV keep switching off by itself?

The reason why your Roku TV is turning off on its own is either because of a power supply issue, because your TV is overheating, or because your TV’s software is outdated.



  • Outdated software
  • Overheating
  • Power supply issue



If you’re in the habit of binge-watching shows on your TV, you will probably face this issue. Letting your TV run for hours and hours on end causes it to overheat- just like any other tech device. In such cases, your TV turns off automatically to protect its internal components from damage.


Outdated software

Another reason why your TV might turn off by itself is that its software is outdated. When your TV updates itself automatically, it usually goes through a reboot before it can apply the new settings. So, your PC turning off can mean that your TV has finished updating and is simply rebooting. If your TV hasn’t been updated and you’re using old software, this issue may arise due to glitches.


Power supply issue

If your TV is old, a power supply issue might be causing your problem. The most common type of power issue is some fault in the power cord, meaning that you’ll have to get it replaced. Unfortunately, doing so is not an easy task, and it requires expertise in electronics. Call Roku’s customer support or get an expert technician to take a look at your TV.



How do I stop my Roku TV from automatically turning off?

You can stop your TV from automatically turning off by giving it sufficient breaks between long use and checking for software updates.


Give your TV Sufficient breaks between long use.

As we mentioned earlier, using your TV for hours and hours without breaks will cause it to overheat. Since this might damage some of your TV’s sensitive internal components, your TV shuts down to prevent that from happening. To prevent your TV from doing so and to prevent it from overheating in the first place, give your TV plenty of time to cool down between each long-term use.


This will cool down your TV’s internals for the next long use and, as a bonus, give you time to rest your eyes as well.


Check your TV for software updates.

Outdated software can cause your TV to turn off automatically. Here’s how you check whether there are any software updates available on your Roku TV:


  1. Find the home button on your TV’s remote
  2. Find settings on the menu that pops up
  3. Click System
  4. Click system update
  5. Find the “check now” button and click it to see whether you have any software updates available.
  6. If there is a newer version ready to be downloaded, click “update” to install the newer version.



Why does my Roku TV’s backlight turn off?

The reason why your Roku TV’s backlight turns off while everything else functions normally is either because of a glitch or because your TV’s internals is overheating.



Sometimes, random unexplained glitches cause your TV’s backlight to turn off mid-use. There is no need to over think this or look too much into the issue; simply power reset your TV to resolve the problem.



Overheating can damage your TV’s internal components, including the backlight. If you’ve been using your TV for multiple hours in a row, its backlight may turn off automatically to prevent further heating. This protects your TV from irreversible damage.


How do I turn on the Roku TV backlight?

To turn on your Roku TV’s backlight, either conduct a power reset or give it time to cool down after long usage.


Power reset

Here are the steps:


  1. Use the remote to turn off your TV and then unplug the power cable
  2. Now, move over to the power button on your TV (not on the remote) and hold it down for 30 seconds. (This is to drain any remaining power from within your device)
  3. Next, leave your TV unplugged for about 5-10 mins
  4. Come back and plug it into the wall socket
  5. Use the remote to turn your TV on



Using your TV for long hours without breaks will cause everything inside it to heat up. So, the solution to this problem is to give your TV long cool down breaks each time you use it for a long. This will prevent your TV’s backlight from turning off.



Why does my Roku TV blink and then turn off?

The reason why your Roku TV might blink and turn off is either because of a power issue or because your TV’s light panel is damaged.


Power issue

An insufficient power supply (usually due to fluctuating currents or a damaged power cord) will mean that your TV won’t have enough electricity to function properly. This might cause your TV to blink and turn off.


Damaged panel

Alternatively, you will experience the same thing if your TV’s backlight panel is damaged (typically the case with older TVs). Get this issue fixed only with the help of an expert technician. If you try to repair your TV on your own, you will risk causing further damage.
