Troubleshooting TCL Roku TV Screen Mirroring Not Working

If your TCL Roku TV screen mirroring not working, then you’ve found the very best post addressing your issue.

Here we’ll discuss what might have gone wrong and how to fix the mirroring mode on TCL Roku TV.

The solution to a non-working mirroring mode on Roku TV includes a power cycle on both your devices and troubleshooting the network. If the mirroring mode is disabled or the devices are not connected to the same network your mirroring mode won’t be able to connect.

There is a lot to discuss so let’s get started with the most frequent causes and then how to solve them efficiently.

Why TCL Roku TV Screen Mirroring Worked Once but Not Working Now?

If the screen mirroring was working in the past but recently you have noticed that the feature is unresponsive, a few things could have happened to your TCL Roku TV:

1. Screen Mirroring Not Enabled

In case you had the screen mirroring enabled in the past but not now, this could be the reason you’re unable to use the screen mirror.

2. An Issue with Your TV

Anything from outdated firmware to a glitchy interface can cause certain features to be inactive.

3. Bad Source Device

If there is an issue with the source device, it is more likely that you will be unable to use the screen mirror.

4. No Using the Same Network

If both your TV and source device are not connected to the same network, they might be unavailable for screen mirroring.

These are the usual suspects, and your issue is most likely related to them.

Next, we’ll start excluding possibilities one by one until you discover the nature of the issue.

How To Fix TCL Roku TV Screen Mirroring Not Working?

Once you’ve gotten familiar with the possibilities for the issue, let’s proceed with the best troubleshooting solutions we’ve managed to bring upon you:

Solution #1 Enable Screen Mirroring

If screen mirroring worked once for you but is no longer available with your new device, it is possible that the screen mirroring is named differently in your interface.

The screen mirroring feature could be labeled differently on your device so here are some examples:

• Smart View
• Quick Connect
• Smart Share
• AllShare Cast
• Wireless Display, and even more.

Note: Try searching for each of these results in your device interface.

Once you’ve found the correct screen mirroring feature, follow these steps:

1. Enter your device interface.
2. Search for Screen mirroring or one of the labels above.
3. Once you’ve found it, click on the result and select Setup Screen mirroring.
4. Follow the on-screen steps and scan for your Roku device.
5. As soon as your Roku device shows as a result of the screen mirroring, select.
6. Establish the connection.

If it does not work, and you still haven’t tried to restart your devices, this is what we’ll be doing in the next solution so let’s jump right in!

Solution #2 Reboot Your TV & Source Device

If after enabling the screen share, the feature is still not functional, try rebooting both of your devices before proceeding.

You might as well power cycle your TV to remove other possible interruptions that might be occurring.

Power Cycle for Roku TCL TV:

1. Unplug the power adapter’s both sides.
2. Wait for 5 minutes.
3. Plug the power adapter’s first end into the power source.
4. Plug the power adapter’s other end into your TV and turn on your TV.

Reboot For Smartphone/Tablet:

1. Hold the power button on your device until a slider appears.
2. Drag the slider towards the power offside.
3. Press and hold the power button for 10 seconds until your device turns on.

Once you’re done, try screen mirroring your devices through the options again and if it is still not working, let’s check for updates!

Solution #3 Update Your Source Device & TV

If the TCL Roku TV screen mirroring is not working, then the firmware versions of your devices might not be compatible with each other.

Thus, it’s possible that you won’t be able to use screen sharing until further notice.

The best workaround would be to update both to the latest possible version of the firmware and then test.

Here are the steps to updating your TV and source device:

Firmware Update for Roku:

1. Go to the options of Roku.
2. Head to the System/Firmware tab.
3. Click on Check for Updates.
4. Click on Apply to initiate the update.

Firmware Update for Smartphones:

1. Go to the Settings.
2. Click on General.
3. Select Software update.
4. Click on the Update window to begin the firmware installation.

Once both devices are up to date, make sure to reboot them again and then try to set up the mirroring.

Solution #4 Connect Device to Same Network

If both of your devices aren’t connected to the same network, your Roku TV will be unable to initiate and allow your smartphone to be screen shared.

To move both of your devices to the same network, follow these steps:

1. Go to the WiFi options on both of your devices.
2. Check if your TV is connected to your home network.
3. Check if your phone is connected to your home network.
4. Connect both devices to the same home WiFi network.

Note: If you’ve split your network into a 2.4GHz flow and a 5GHz flow, you must ensure that both of your devices are paired with the same connection.

Solution #5 Resolve Network Issues

Now when you’re certain that both devices are up to date and using the same network, the possibility left would be a network issue.

As you probably know, to communicate both devices require a reliable internet connection so let’s inept your network.

To inspect and resolve network issues do the following:

• Reboot your router.
• Check signal strength (if weak, move closer to the router).
• Remove any electronic devices around your router.
• Call your ISP.

Note: You can run a free online internet speed test, to determine whether there is something wrong with your network or not.

Solution #6 Factory Reset Your Source

Since there is not much that could go wrong with your TV, the main suspect remains your source device. If nothing has worked so far then you should revert your source device back to factory settings.

Note: Mind that the factory reset will erase all current contents on your smartphone, putting them back as it was when you first opened it.

How To Factory Reset Source Device?

1. Go to Settings > System.
2. Click on Erase.
3. Select all Phone contents.
4. Confirm by entering your password.
5. Wait for several minutes.

How To Factory Reset TCL Roku TV?

1. Press the home button on your remote.
2. Next, go to System.
3. Scroll down and choose Advanced system settings.
4. Then go to Factory reset.
5. On the next screen, choose Factory reset everything.
6. Wait for the reset to complete.

Once ready with the factory restore, simply set up both devices and test if the screen mirroring will finally work.

To fix a not-working screen mirror feature, reboot and power cycle both of your devices and connect them both to the same network. Then, try re-enabling the screen mirroring feature, update their firmware, and lastly perform a factory default reset.
