Your Roku TV’s screen may be getting darker than normal. This can be caused by several issues, including a dead backlight or an intermittent power supply. There are ways to solve this problem, including rebooting your device and turning off local dimming. If none of these solutions work, try contacting Roku customer support.
Changing the picture mode in the Roku TV’s settings may also solve this issue. This method is useful if the issue is occurring when playing video content, such as youtube. It may also be caused by a recent update. To power cycle your Roku TV, simply turn it off and hold the power button for ten to fifteen seconds. The screen should brighten up again after this. You can also try playing a movie or shoes on the television to see if the issue has been fixed.
If the problem is related to the display, you should first check the display. Some Roku TVs have eco lighting, which is an energy-saving feature. This feature dims the screen when the surrounding light is too bright or too dim. Depending on your model, the display can be set to increase brightness in low light conditions. You can also set the TV to a black tone, which makes dark regions appear darker while bright areas are bright. If none of these steps work, contact Hisense customer support.

How Do I Stop My Roku From Dimming?
If you want to prevent the screen on your Roku TV from dimming, the first step is to find out which settings are to blame. This problem might be caused by a defective backlight, or it could be a temporary glitch. In any case, there are some things you can do to fix the problem and keep the TV bright.
First, check whether the local dimming option is turned on. Using this setting will enable your television to have optimal contrast and brightness. Also, you should turn off the auto-dimming feature. If the problem persists, you can also try to update your Roku TV’s firmware. To do this, you need to go into your system settings and choose the “Check Now” option. After this, restart the device to see the changes.
Another common reason for a dimmed TV is a problem with the power cord. Make sure the cord is tight and secure. Alternatively, if you have a weak power source, try re-plugging the TV in another outlet. If this doesn’t work, you can try hard-resetting your TV. This involves unplugging it from the wall and holding the power button for 30 seconds.
Why Does My TV Change Brightness by Itself?
If your TV is constantly changing brightness, there may be an issue with the backlight. Check the settings on your TV and disable local contrast and local brightness, if applicable. Then, enable Adaptive Brightness to adjust the display brightness depending on the surrounding light. This mode detects your environment and automatically chooses the best brightness for your viewing environment.
If the brightness problem continues, you can try updating the firmware of your Roku TV. This will ensure that it is operating at optimal efficiency. In addition, you can adjust the display brightness, contrast, and Gamma settings. The default Gamma setting is 2.2, but you can adjust it to 2.0 or lower to see a more natural contrast.
Another possible cause is incorrect picture mode settings. If your TV is displaying too dark or too bright, check whether your settings are set to Eco lighting or Dynamic contrast. These settings prevent your TV from dimming when the room light changes.
Why Does My Roku TV Keep Getting Dark?
If your Roku TV keeps getting dark, you may be experiencing a software issue. If this is the case, you can perform a soft reset by unplugging it for around 30 seconds and then plugging it back in. This reset will reset the TV’s hardware and software settings. Depending on the model, the TV may also have a feature known as local dimming to enhance contrast.
You can also try a hard reset. This will restore your television’s settings to their factory defaults and erase any downloaded applications and saved information. To do this, press the Home button quickly five times and then press the Rewind and Forward buttons twice. When you have completed the hard reset, turn off your TV. If the problem persists, you can try replacing the HDMI cable or source device with a known-good replacement.
Another common cause for a dark screen is an incorrect resolution. You may want to use a power tester to check if your Roku TV has plugged the power cord into the wall. If the problem continues, you can also try changing the resolution of your television.
