Roku TVs are great affordable smart TVs with tons of features. Many TV brands and manufacturers partner with Roku to make the TVs. But sometimes the Roku TV won’t turn on.

Whether the Roku-based TV is made by TCL, Hisense, Westinghouse, Element, Philips, Samsung, or Vizio, there are any number of reasons the TV is not turning on. This can happen because of hardware issues, bad connections, or even a power outage.

In this post, I’ll go over how to fix Roku TVs that won’t turn on. I’ll also explain why these problems happen and how to fix them.

Roku TV Not Turning On

1. Change the Input Source to the Roku TV

This may seem like an obvious fix, but sometimes we forget that we can change the input source in the settings menu. 

If the Roku TV shows that it’s “on” but there’s nothing on the screen, the TV could be on the wrong input source. So that’s why the TV looks to be off and not turning on. 

To change the TV’s input source with the remote control: 

  • Press the Source button on the remote control.
  • Choose the correct input source.

To change the TV’s input source without the remote control: 

  • Press the physical Menu button that’s on the bottom or side of your TV.
  • Select the correct input source by using the volume buttons to navigate.
  • Choose the input source by pressing the Menu button. 

Some Roku TV models may alternatively have a specific input source button on the bottom, side, or back of the TV. Check for that as well. 

2. Loose Power Cord on the Back of Roku TV

Check the power cord in the back of the Roku TV and to the power outlet in case the power cord is loose. 

Make sure to tighten both connections, so they’re not loose. 

What you can also do is to unplug the power cord on the TV and plug it back in tightly. 

Press the Power button on the Roku TV itself and see if the power comes on. 

3. Try a Different Power Outlet

Another possible issue is the power outlet that the Roku TV is connected to. There might be a blown fuse or another issue.

Check the power outlet to see if electricity is coming out of the wall socket by plugging your phone charger into it. If your phone is charging, that means there’s power coming out of the wall socket and the TV has an issue.

If there’s no power coming out of the power outlet, try to plug the TV into a different power outlet to make sure the Roku TV also hasn’t shorted out or had any other issue. 

4. Try a Soft Reset of Roku TV

A soft reset or power cycle can help reset any issues with the Roku TV if your TV won’t turn on.

  • Unplug the Roku TV from the power outlet.
  • Wait 60 seconds.
  • With the TV unplugged, Press and Hold the Power button for 30 seconds.
  • After 60 seconds, Plug the TV into the power outlet.

See if this fixes the issue and the Roku TV turns on again. This should fix the issue for 3 out of 4 cases. If it doesn’t, try the other solutions below. 

5. Replace the Remote Control Batteries

It could be that the Roku TV remote is out of power, so the TV won’t turn on. Changing the batteries and putting in a fresh set will help with the issue.

A soft reset of the remote will also help. 

  • Take both batteries out of the remote.
  • While the batteries are out, Press and Hold the Power button on the remote for 30 seconds.
  • After 30 seconds, put fresh batteries into the remote.
  • Try to turn the TV on.

If this fixes the Roku TV temporarily, but then it continues to happen again, a factory reset might be needed to make it more of a permanent fix.  

6. Factory Reset the Roku TV

A factory reset of the Roku TV will reset the TV back to its original, factory settings like when you first purchased and turned on the TV. 

While the TV is on: 

  • Go to Settings
  • Select General
  • Select Reset
  • Enter in your Security PIN (default is “0000”)
  • The TV will now turn off and on again by itself.
  • Go through the initial setup process.

7. Factory Reset the Roku TV Without a Remote

If you can’t find your remote, don’t worry. You can still perform a factory reset on your TV without a remote control. 

Here’s how to do a factory reset without a remote on a Roku TV: 

While the Roku TV is on, go to the TV’s Menu by Pressing the Menu button

  • Go to Settings
  • Select General
  • Select Reset

If the Roku TV is positioned in a way that you can’t access the buttons or they’re not working, there are other options to access the menu options. 

8. Backlight is Broken on the Roku TV

A broken backlight on the Roku TV is a possibility if you’ve tried the above fixes. 

Here’s how to test if your TV’s backlight is broken: 

  • Turn on your Roku TV
  • Turn on a flashlight and point it at the TV screen. Bring it as close as you can. 
  • See if you can see an image on the TV screen with the flashlight. 
  • If you see any images on the screen, that means the TV’s backlight is broken and needs to be replaced.  

9. Replace the Power Supply

Your Roku TV may need a new power supply. The power supply is what provides electricity to the TV. It powers all the components inside the TV, including the main board, display, speakers, etc. 

If you see that there are no lights, including the standby light, that are on, it could be that the power supply board isn’t working correctly and needs to be replaced. 

A replacement power supply isn’t expensive either, usually under $100 if you can replace it yourself. 

10. Fried Motherboard in the Roku TV

Much like a computer, a Roku smart TV has a motherboard to control many of its features and functions. 

If the motherboard has any issues, it would lead to the Roku TV not turning on. 

Motherboards are inexpensive and can be replaced by yourself. But with something like this, unless you’ve done something similar to this on a computer, it’s best to take it back to the store or call in tech support.  

11. Check if You Have an Active Warranty on the Roku TV

If all else fails, check if you have an active warranty on the Roku TV. The manufacturer’s warranty may cover the cost of repairing the TV if it breaks down. Some warranties will replace the whole TV instead. 

You may also be able to purchase a warranty from the retailer where you purchased the TV. Retailers often offer extended warranties on products you purchase from them.

These extended warranties are often better than the manufacturer’s warranty. When it comes to a big ticket item like a smart Roku TV, the extended warranty is often recommended.
