For some users, they have a black screen (i.e no picture) and also can’t hear any sound on their Roku TV. For other users, they have a TCL Toku TV black screen issue, but sound works just fine. Whichever category you may fall into, this guide will cover everything you need to know in order to fix the issue quickly.

Without any further ado, let’s dive right in!

TCL Roku TV Black Screen Fix

To fix a TCL Roku TV black screen issue, you need to first restart or power cycle your Roku device. Next, you should check the cable connections (power cable & outlet, HDMI cable and HDMI port). Then, you need to clear the TV cache and restart it again. If you still have the issue, then you need to reset your Roku TV.

If you are wondering how to reset a TCL Roku TV with black screen, I will show you how to do just that later. First, let’s start with the simple but effective fixes that do not require a reset.

1. Restart Your TCL Roku TV

If you have a black screen on your TCL Roku TV, the first thing you need to do is restart it.

Because it sounds too simple, a lot of users think that makes it less effective and search for more “technical” solutions instead.

To restart your Roku device using your remote controller, follow the steps below:

  • Press Home on your Roku remote.
  • Scroll and select Settings.
  • Select System.
  • Select System restart.

  • Finally, click on Restart.

Once your devices boots up again, the black screen issue on your TCL Roku TV should be fixed. Otherwise, you need to power cycle the device. 


2. Power Cycle Your Roku TV

One of the most effective fixes for TCL Roku TV black screen issue. If a simple restart didn’t fix the issue, you can take it a step further with a power cycle or soft reset (by the way, a soft reset does not touch any of your saved settings or installed apps/channels).

That said, here’s how to power cycle your TCL Roku device to fix the black screen issue:

  • Turn off your Roku TV
  • Next, unplug your TCL Roku TV from the power outlet
  • Press and hold down the power button on your TV for 30 seconds
  • After that, plug it back in and turn it on
  • Now, your Roku device should have picture and the black screen issue should be fixed.

If that worked for you, good. Otherwise, move on to the next step.


3. Check Power Outlet & Cable

A faulty power outlet is another reason why you may be seeing a black screen on your TCL Roku TV. The power outlet may be faulty and not delivering enough power to your Roku device.

Therefore, try plugging in your TCL Roku TV into another power outlet that you are sure is definitely working. You can of course check that by plugging in another device into the power outlet to check if it works.

In addition, you need to check the power cable in case it’s faulty. It is one thing to have a working functional outlet, it is another thing for the power cable to actually be working.

If you have another power cable, you can switch it to your Roku TV and try to turn it on. If that fixes the issue, then the power cable is responsible for the black screen on your TCL Roku TV. In addition, make sure the cable is plugged in securely for proper connection.


4. Check HDMI Cable & Port

If you connected your TCL smart TV to your Roku device via HDMI cable, then you need to check both the HDMI cable and HDMI port. There are 2 possible scenarios that could cause your TCL TV to show a black screen when connected via HDMI:

  • Your HDMI cable is faulty
  • Your HDMI cable is working, but plugged into the wrong HDMI port

You can begin by switching your current HDMI cable into a different HDMI port, while making sure that the selected input source on your TCL TV correlates with the port you have the cable plugged into. You can switch the input source on the home screen.

If that doesn’t work, then you need to try a different working HDMI cable. Also, ensure that the cable is securely plugged into the port for proper connection. If the issue is coming from the HDMI, switching the HDMI cable or port will fix that.


5. Clear Roku TV Cache

Another way to fix a black screen on your TCL TV is to clear the cache and allow the device to restart itself. This applies if you Roku TV actually turns on, but later shows a black screen when you try to stream a channel.

On the other hand, if your Roku device won’t even turn on at all, then there’s no way you can apply this method, so just move to the next one.

That said, here’s how to do clear your Roku TV cache:

  • First, select the Home tab
  • Now, press the ‘Home’ button on your TV remote 5 times
  • Next, press the ‘Up arrow’ ⬆️ button on your remote once
  • After that, press the ‘Rewind’ ⏪ button twice
  • Then, press the ‘Fast forward’⏩ buttontwice

The device will freeze for a few seconds and then restart automatically. Once it comes back on, the black screen issue should be fixed. Otherwise, move to the next tip. 


6. Perform a Hard Reset

If your TCL Roku TV still has a black screen, then you need to perform a hard reset (i.e factory reset). There are two ways to do this:

  • The first method which can only be done on settings dashboard applies only to those who can see a picture on their TCL Roku device, but only shows a black screen only when they try to stream or open an app
  • The second method applies to you if you can’t even see any picture at all in the first place, and hence can’t access the settings dashboard. However, the people with TCL Roku TV black screen with sound can also use this method.

Now, here’s the first method to perform a hard reset on your TCL Roku TV:

  • Click on Home button on Roku remote
  • Scroll and select Settings
  • Select System > Advanced system settings > Factory reset

reset TCL Roku TV to factory settings

  • Finally, enter the code displayed on the button right corner and click on OK.

On the other hand, if you don’t have picture at all, you can use the physical reset button on the TV. Here’s how to do that:

  • First, locate the physical reset button on your TCL Roku TV (on the back or bottom of your TV). It will look like any of the images below:

  • Once you locate the reset button and, press and hold the button firmly for about 10 seconds while your device is powered on. When it shuts down, keep holding down the reset button until it powers on and shows the TCL Roku TV logo again. Then, you can release the button
  • When the factory reset is complete, the TV will reboot twice and finally turn on

Now, your Roku device will restart like a brand new one. Go ahead with the activation and configuration. Once done, the black screen issue should be fixed.


7. Check for Faulty Backlight

Your TCL Roku TV could be on, but if the backlight is defective, you will not see any picture at all on the screen. You will basically just have a black screen on your TV.

So, how do you check if the issue is with your TV backlight?

  • First, make sure your TV is plugged into the power outlet
  • Next, point a flashlight to your TV screen (you can also move it around the screen).
  • If your TV backlight is working well, all you should see is the reflection of the flashlight.
  • However, if you can see dull images on the screen while pointing the flashlight, then your TV backlight is defective.

In order words, your Roku TV is on, but the backlight needed to show bright images is faulty. Therefore, you might see a black screen that turns purple or dark blue with sound on.

The backlight can be fixed by replacing the LED strips on the screen. It’s a quite a tricky process, and I will advise you get it fixed by an expert. Considering the cost of fixing this, your best option might be to get a new TV.

While a faulty backlight is one of the most common reasons why your TCL Roku TV might have a black screen with sound, there are other potential causes and ways to fix it appropriately in such cases. Now, let’s look at some ways to fix a TCL Roku TV black screen with sound.

TCL Roku TV Black Screen With Sound

If your TCL Roku TV screen is on with sound, but the screen is dark totally or only when you try to play a show or movie, then you most likely have a faulty backlight strip. You can check if the backlight is faulty by pointing a flashlight to the TV screen. If you can see dull images, then the backlight is defective. 

However, if your backlight is not defective as shown by the quick flashlight test, there are some other ways you can fix the black screen issue then.

First, let me mention that the tips I discussed in the previous section still apply here too and can help you fix the issue. Therefore, make sure you try those first if you haven’t. If none of them work for you, then proceed with the ones below:

  • Check Your Internet Connection

If your TCL Roku TV screen goes black only when you try to stream on it, then you may have a slow internet connection.

First things first: You need to check the status and signal strength of your internet connection on your Roku device.

  • To do that, go to Settings > Network > About, and see if it’s showing ‘Connected’ or not. 
  • On the same page, you will find the signal strength, is it showing ‘Poor’, ‘Good’ or ‘Excellent’?

Roku TV network settings

If the network is not connected or the signal strength is poor, this might be the reason why your Roku device is lagging when streaming. 

  • Finally, click on Check Connection.

You Roku device will start checking your Wireless/Wired connection and Internet connection.

Once the check is complete, you should see a prompt showing ‘Connection check was successful

connection check successful

If the connection check was not successful, check your network router and setup the connection. Otherwise, if it was successful, there are still other things you need to check to fix your network issue. These include:

  • Restarting your network router
  • Switching to another network router, especially a dual band router with 5.0 GHz frequency
  • Switching to hardwired ethernet connected instead of Wi-Fi

If the issue is coming from your network connection, any of these aforementioned tips will help you fix it successfully.


  • Check for Software Update

Nothing much to say here. If your TCL Roku TV software is outdated, then you need to update it to the latest version.

Here’s how to check and update your Roku software:

  • Click on the Home button on your Roku device remote
  • Select Settings > System > System Update
  • Click on Check Now to manually check for any update

If there is any available software update, your Roku device will download it, install it automatically and then reboot once completed.

NOTE: Your Roku device should be connected to the internet for you to use this method. Otherwise, try the manual update method.


  • Re-install the Channel Affected

If your TCL Roku TV black screen issue only happens when you try to stream specific channel(s) like Netflix, Hulu, Sling, Amazon Prime, Disney Plus or YouTube, then you need to delete the channel and re-install it.

This is a three-step process: First, you remove the app that causes your TCL Roku TV screen to go dark. Next, you restart your Roku device to clear the cache. Finally, you add the channel to your device again from the Roku channel store.

Now, here’s how to go about it:

  • On the Home Screen, click on ‘Streaming Channels’
  • With your remote controller, hover on the channel on you wish to remove
  • Press the * (star) button on the remote to bring up the options menu
  • Select ‘Remove channel’ and then, click on ‘Remove’ to delete the channel
  • Finally, restart the Roku device.

Once the Roku device has booted up again, you can now proceed to add the channel back from the Roku channel store by following the procedures below:

  • Press ‘Home button’ on your Roku remote
  • Select Streaming Channels to open the Channel Store

If it’s a popular/featured/new channel, you may find it at the top of the Roku channel store under featured, new and popular categories. Otherwise, click on ‘Search Channel’ 

  • Once you find the channel, hover on it and click on ‘OK button’ to view the details
  • If it’s a free channel, click on ‘Add Channel’.

Once done, try to open the channel again and the issue should be fixed.


  • Contact TCL Roku Support

If you have followed all the tips stated above, your TCL Roku TV black screen issue should be fixed by now.

However, if the issue still persists, the only thing you can do is to contact TCL Roku for support. The contact number is 1-877-300-8837
