First, try performing a power reset on your TV. This process, also known as a reboot or power cycle, involves unplugging the power cable from the wall outlet and then plugging it back in.

While this may seem like a simple solution, it is effective in about 90% of cases. Simply unplugging and replugging the power cable can often fix the problem.

Here’s how to do this:

  • First, unplug the power cable from the wall outlet, and then,
  • Wait at least 60 seconds before plugging it back in.
  • While your TV is unplugged, locate and press the power button for 30 seconds.

Ensure that you’re pushing the power button on your TV, not the remote!

Now, try turning your TV back on to see if the issue has been resolved. If not, proceed to the next step.

2. Check the HDMI input

If the power cycling does not resolve the issue, the next step is to check and ensure that the TV is connected to the correct input. An incorrect input selection can make your TV appear turned off even though it is still receiving power. So ensure that your TV source and input match the number of HDMI ports you use.

For example, if you’re using a streaming device with HDMI port 1, set the TV source and Input to HDMI 1. If you’re using a DVD player with HDMI port 2, set the TV source and Input to HDMI 2.

Also, check the HDMI port and cable for visual damage and ensure the cable is firmly connected on both sides. If you find any visible damage, replace it.

3. Force hard reset your TCL TV

If rebooting and then selecting the correct HDMI input source does not resolve the black screen issue on your TCL Roku TV, there is only one option left for you to try: a factory reset. This is a process in which you restore the television to its original factory settings.

It is possible that your television is experiencing an internal software-related error, which is causing the screen to remain blank. In such cases, a factory reset may fix the issue. However, refer to our guides for instructions on resetting your TCL Roku TV to its default state.

Did nothing fix your TV’s black screen issue?

If none of those mentioned above steps resolve your issue, then check the following things:

1. Is TV’s backlight working?

TV’s backlight can become damaged for various reasons, such as a sudden electrical overpower flow or other unforeseen circumstances. When this occurs, the backlight may no longer function properly, leading to a poor display or black screen.

However, you can easily check if this is the case! Here’s how to do this:

  • Turn on your TV and bring a flashlight close to the screen.
  • Shine the light on the screen and observe whether an image is visible.

If an image is present but appears very faint, your TV’s backlight likely needs to be replaced as it has been damaged.

2. Is the T-con board damaged?

The T-con board is a crucial component that connects to the mainboard, generates horizontal and vertical timing panel signals, provides panel bias, and enables video signals. If the T-con board is malfunctioning, it will result in the TV displaying a black screen.

Remember that if the backlight or the T-con board is damaged, you will need to have them repaired or replaced. Contact TCL customer care for assistance if your TV is still under warranty. Otherwise, visit a nearby TV repair shop for assistance.
