The first step is to open the settings menu. This will bring up a dialog box that lists numerous settings. Highlight the option you want and then press the “OK” button to confirm it. The change will instantly show up. When you’re watching a movie, for example, you may want to increase the brightness of the picture.

How Do I Fix the Backlight on My TCL Roku TV?
The first step is to diagnose the problem. If the backlight isn’t working, it could be due to a hardware or software issue. Backlights are necessary for presenting images, so a malfunctioning backlight will make your television screen appear dark. If you’re not able to diagnose the problem, you can take it to a specialized repair shop.
Another common problem with LED backlights is a faulty power supply. If your TCL Roku TV isn’t receiving enough current, the LEDs will not turn on. To check whether your LEDs are getting the correct amount of current, you can test the voltage on the power board. If it’s still not working, you can try replacing the board, which can cost up to $200.
Another way to fix the backlight on your TCL Roku TV is to try to hard reset it. This will return the TV to its factory default settings. However, this will delete any apps and saved information you might have saved on the device. To do a hard reset, press the Home button quickly five times and press the Rewind or Forward button twice. When the process is complete, turn off the TV and re-download all the applications and personal settings.
Why is My Hisense Roku TV Screen So Dark?
A black screen can be an indication that the backlight on your Hisense Roku TV has failed. If this is the case, you can try restarting the TV to restore brightness.

In some cases, a damaged USB cable may also cause the TV’s screen to become dark. If this is the case, contact Hisense support and ask for help. If you do not have access to a local repair shop, you can opt to send your TV in for service. The cost will depend on the level of diagnosis and whether the work is covered under the warranty.
