Devices, especially routers and phones, are nearly always instructed to be rebooted as the first line of defense against problems that may arise.

And despite the fact that you may be hesitant, it can also work quite well for your television.

Your device’s hardware and software will both be restarted when you do a reboot.

As a consequence of this, any little issues that may be the root cause of the black screen will be resolved, and you will once again be able to take pleasure in seeing high-quality images.

Rebooting your TCL Roku TV is as easy as unplugging it from the power outlet (but without turning it off), waiting around one minute, and then plugging it back in and turning it on again.

The majority of the time, following this technique will resolve any small issues that have been impacting your TV.

Method 2: Reset your TV to the factory settings.

Did the reboot not work? The problem can be a little bit more severe, for example, the settings on your TV might be compromised.

In such a scenario, doing a reset to factory settings could be able to assist repair the problem.

There are primarily two methods available for resetting your TV:

By navigating to the settings menu

People who posted on online forums said that activating or removing the Fast Start option of their TCL TV resolved the issue of their television having a black screen.

It is something worth checking out whether you had it disabled or not, and I will walk you through the process of enabling it if you had it disabled or disabling it otherwise below.

Please follow these instructions for the TCL Roku TV:

  • Step 1: Press Home button

Using the remote for your Roku TV, press the Home button.

  • Step 2: To access the system, go to Settings > System.

  • Step 3: Select the Fast TV Start option.

  • Step 4: Alter the settings

Select “Enable” or “Disable” for the Fast TV Start option, as appropriate.

By doing a factory reset

It is necessary to do a hard reset in order to access the menu, since photographs must be present for this option to be available.

  • Step 1: Navigate to the rear of your television set.

Proceed to the TV’s rear panel or one of the side panels (where HDMI and other connector ports are located).

  • Step 2: Press the button labelled “Hard reset.”

Locate the button for the factory reset and then push it (you might need a sharp-pointed object for this).

  • Step 3: Hold the button down for 12 seconds.

After keeping your finger on the button for around 12 seconds, you may let go (your TV will power off).

  • Step 4: Press the Power ON button

Turn on the television and finish the steps in the guided setup process.

Performing a factory reset will result in the deletion of all settings, including network settings, as well as any stored data.

As a result, after you are finished, you will need to go through the process of setting up your Roku account all over again.

Method 3:  Make sure the cable connections are secure.

  • HDMI cable
  • HDMI 2.1 cable

Do you intend to connect the Roku cable box to the TCL television set? It’s possible that the issue is caused by sloppy cable connections.

If the HDMI cables are broken in any way, this may be a very severe situation, so check to be that they are in good condition.

There is a possibility that the power cords are either broken or have become loose due to which the screen might glitch.

Consider purchasing the a high-speed braided cable in the event that the HDMI cable seems to be defective.

It is possible to stream HD material without experiencing any latency, and since it is braided, there is a much-reduced risk of the cable being damaged. Amazon is a good place to look for the cable.

Your TCL Roku TV comes pre-loaded with firmware, which, for maximum performance of your device, has to be kept up to date.

  • Step 2: Traverse to systems update
