From there, select system update. Make sure not to turn off or unplug the TV while the update is taking place.
A broken backlight can be caused by several issues. A black screen with sound is the most common issue, but other problems can also arise. If the screen is gray or dull, the problem may lie with the LED strips.
How Do I Fix a Backlight Problem on My TV?
If your backlight isn’t working, you should check the circuit board. Usually the led driver board is located on the powerboard, but some have a separate board. You can use a multimeter to check individual pins. If the readings are high or low, the board is bad and needs replacement. If you’re unsure where to start, read the user manual for more information.
First, you should make sure the screen is dark. If the screen is too dark, the problem may be with the LED backlights. Another sign that the backlights are failing is a dim image or flickering. The backlight strips are located on the bottom of the television, and if they’re failing, they won’t project the image correctly onto the screen. Fortunately, diagnosing the problem is simple. To do this, first power down the screen. Next, unscrew the metal sheeting covering the LED panel. Then, carefully remove the LED panel from the back of the TV.
If the backlight isn’t working, you can try replacing the LED strips on the screen. This may fix the backlight issue. However, you should be aware that you may have to buy a new television if the LED strips on your TV have failed.
How Do I Fix My Roku Dim Screen?
Changing the backlight can be a quick fix if the screen appears too dim or black. The backlight is controlled by the LED strips, which are usually connected to the power board.

Alternatively, you can use the Ambient Light Detection function to automatically adjust the screen brightness based on the amount of light in the room. This will enhance the quality of your picture.

What Causes Backlight Failure?
A backlight failure occurs when the LEDs in the backlight are not working. This issue can result in poor picture quality. To find out whether the LEDs are functioning, turn off the TV and use a flashlight to look at the LED panel. If you can see a shadow in the panel, the backlight is not working and you should replace it.
The backlight may also fail if the power circuit of the TV is not working properly. This problem can be caused by broken LEDs or by a defective power supply board. In some cases, the backlight LEDs could have moved inside the television. Luckily, this problem is easy to fix and can be easily solved.
LED backlight failures are a common problem among low-end LCD and LED televisions. When the backlight fails, the TV displays a black screen when the screen is turned on.
Why Did My TCL Roku TV Go Dark?

Once you have finished, your TV should be back to normal and you should see a full picture again.
If the problem persists, you may want to contact the company’s Customer Support for assistance. While you can usually fix software issues over the phone, there are times when the television will need to be sent to a technician for repair. If this is not an option, you can also try to find a TCL authorized repair center.
A hard reset will return the TV to factory defaults and will delete all downloaded applications and saved information.
