I had tested a few universal remotes for my TCL TV earlier, and during my testing, the TV randomly gave me a black screen almost three times.

Since I review many products with my TCL TV, it was obvious that this was going to be an issue later on.

I talked to TCL support and did quite a lot of research online, and tried a whole lot of fixes.

I documented what I found in detail to make this guide to help you fix your TCL TV that's going black.

To fix your TCL TV that's showing you a black screen, restart the TV. If it doesn't fix the issue, change the HDMI cables.

I've also gone into detail about how to Reset your TCL TV.

Possible Reasons For TCL TV Black Screen

A black screen can be a sign of a more serious underlying problem, and identifying what that issue is is the first step to troubleshooting.

One of the probable reasons why this can happen is an issue with the HDMI cable that outputs the display from whatever device you are using the TV with.

Another reason can be that the TV's backlight is failing. Most TVs rely on a backlight to light up the image, and an issue there can cause black screens.

Other possibilities include a software bug in the TV or the device you are using with the TV.

But don't worry, with this guide I aim to fix whatever issue that your TV has, as easy as possible.

Power Cycle The TV And Remote

The first order of business to any troubleshooting guide is the restart. In this case, we are trying a type of restart called a power cycle.

As you might have guessed from the term, a power cycle is basically unplugging or removing the power source, leaving the device off for up to a minute, and plugging it all back in again.

A power cycle can take care of issues that occurred due to an accidental setting change that either you made or was done automatically made that caused the TV to turn black.

To power cycle your TCL TV:

1. Turn off the TV. Wait until all the status lights on the TV go off.
2. Unplug the TV from the power outlet and wait for 1-2 minutes.
3. Plug the TV back in and start it up again

To power cycle the remote:

1. Remove the batteries from the remote.
2. Wait for 1-2 minutes.
3. Insert the batteries back in.

To test if you have fixed the issue, try to reproduce what you were doing when the black screen appeared. Use the TV normally and watch out for the black screen to reappear.

Power Cycle the TV Using an Alternate Method

There is another way to power cycle the TV if the method described above doesn't work.

First, you'll need to get your hands on a paperclip or something similar. Then:

1. Turn off the TV and unplug it from the wall.
2. Find the reset button on the side of the TV. It looks like a tiny hole that only a paperclip can enter.
3. Press and hold this reset button for at least 30 seconds.
4. Power the TV back on.

Reproduce the exact situation again and confirm that the issue has been fixed.

Restart the TV Using the Remote

This method is applicable only for TCL Roku TVs. You can restart the TV by pressing a certain key combination on your remote.

This combination is pretty easy to execute and is detailed below.

1. Press Home five times
2. Press Up once
3. Press Rewind twice
4. Press Fast forward twice

Once you correctly complete the combination, the TV will begin its restart. Use the TV as you would normally after the restart and look if the issue persists.

Check the Cable Connections

I had indicated before that a probable reason for a black screen on any TV could result from the connections being loose or the cables being damaged. Go to the back of the TV and check if all connections are intact.

If your HDMI cable is getting old, I'd suggest getting a replacement.

Even if you are using the stock HDMI cable that came with the TV, getting a new one from a good brand like Belkin is a good idea.

I'd recommend getting the Belkin Ultra HD HDMI cable .

It's gold plated, so you can rest assured that it will last forever and has great speeds that ensure a lag-free display.

Update Your Firmware

Software on TVs has started getting frequent updates ever since TV moved to the Android ecosystem, and the TCL TV is no exception.

Software updates fix issues major and minor all the time, so it would be a good idea to update your TV as well.

For Android TVs, a software update updates the TV's firmware, so it is easy to check and install firmware updates.

To update your TCL Android TV:

1. Press the Home button on the remote and navigate to the Settings menu.
2. Open the Settings menu and select More Settings.
3. Choose Device Preferences>About.
4. Select System Update
5. Select Network Update from the box that is displayed.
6. The TV will look for a software update and, if available, download it.
7. After it finishes, click OK to confirm.

Tweak Fast Start Option

People on forums online had reportedly fixed their black screen by either enabling or disabling the Fast Start option of the TCL TV.

Enabling it if you had it disabled or disabling it otherwise is something worth checking out, and I will guide you through the process below.

For the TCL Roku TV, follow these steps:

1. Press the Home button on the Roku TV remote.
2. Navigate to Settings > System.
3. Choose Fast TV Start
4. Enable or Disable Fast TV Start as applicable.

For TCL Android TVs:

1. Open the Settings menu.
2. Select Power
3. Change the "Instant power on" setting as applicable.

Restart the TV and check if the issue has been solved.

Factory Reset the TV

A factory reset must be your last resort chiefly because a factory reset will wipe all settings and logged-in accounts from the TV.

You'd also have to go through the initial setup and connect to your WiFi network again.

To perform a factory reset on your TCL Roku TV,

1. SelectSettings
2. Scroll down to find and selectSystem
3. Go toAdvanced system settings >Factory Reset.
4. SelectFactory reset everything.
5. Enter the code on the screen to proceed with the factory reset.

To reset everything to factory defaults on an Android TV,

1. From the home screen, press the settings button on the remote.
2. Navigate toMore Settings >Device Preference >Reset.
3. ChooseFactory data Reset.
4. SelectErase Everything.
5. Enter the PIN displayed on the screen and press OK.

Final Thoughts

TCL TVs are very good for their price. It is a great choice for anyone who is looking for a 4K TV but doesn't want to splurge on a Sony or an LG and at the same time not miss out on features.

Sometimes the TV is not the only thing that can stop working. Sometimes the Roku remote doesn't work well but fixing it is quite easy.

All in all, TCL's Android TVs and their newer Roku TVs are a great choice for your first smart home entertainment system.
