What to do if the screen of the Xiaomi TV F2 50 dims or glows abnormally?

If the Xiaomi TV F2 50 screen dims or glows abnormally, please refer to the following scenarios and their troubleshooting methods:
Scenario 1:
If the issue occurs when you are using apps on your TV, please refer to the following methods:
1. Consider the lighting conditions in the room. Excessive ambient light can cause the TV screen to appear dim. Additionally, if the room is too dark, it might cause the screen to appear abnormally bright;
2. Turn off the TV and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can sometimes resolve temporary display issues;
3. Navigate to [Settings] >> [Display & Sounds] >> [Picture Settings] >> select the input source >> check for the brightness, contrast, and other display settings;

4. Clear cache and data by going to [Settings] >> [Applications] >> [Manage Installed Applications] >> select the app >> [Clear data] or [Clear cache];

5. Make sure that the app is up to date. Go to the Home screen >> select the [Search for] icon with your remote >> go to [Appstore] >> select the app you want to update >> press the three-horizontal-lined button on the remote control >> select the [More Info] option and update the app;
6. Reinstall the app and see if the issue still persists. Go to [Apps] >> select [My Apps] >> select the app and press the three horizontal lines button on the remote control, select [Uninstall] and then reinstall the app;
7. Ensure that your TV's system and the apps you're having trouble with are up to date. New updates might resolve bugs causing login and syncing issues. Go to [Settings] >> [Device & Software] >> select [About] >> select [Install Update];
8. If all other methods fail, please reset your TV to the factory defaults. Go to [Settings] >> select [Device & Software] >> scroll down to find [Reset to Factory Defaults] and select it.
Here are some friendly tips:
1. A factory reset will delete all user data, including installed apps, accounts, settings, and personal files;
2. Before initiating the factory reset, make sure to back up any critical data. This might include photos, videos, documents, app data, and any other files you want to keep.

Scenario 2:
If the issue occurs when you are using external device like DVD player or game console, please refer to the following methods:
1. Disconnect any external devices (such as gaming consoles, Blu-ray players, etc.) connected to your TV. Test if the issue persists with only the TV itself;
2. Ensure that all cables (such as HDMI, power, etc.) are properly connected to the TV. Sometimes loose connections can cause display problems;
3. If you're using external devices like a gaming console or streaming device, try using a different HDMI cable to rule out cable issues;
4. Switch to a different HDMI input on your TV to see if the issue persists. This can help determine if the problem is specific to one input or affects the entire TV;
5. If the issue is related to an external device, check for firmware updates for that device.

Scenario 3:
If the issue occurs when you are using casting on your TV, please refer to the following methods:
1. Please ensure that both the casting device such as your computer or your smartphone and your TV are connected to the same Wi-Fi network;
2. Navigate to the TV's settings and check the picture settings. Please navigate to [Settings] >> [Display & Sounds] >> [Picture Settings] >> select the input source >> check for the brightness, contrast, and other display settings;
(The pictures are the same as Scenario 1.)
3. Check the casting device settings (e.g., smartphone, tablet, or computer) for any display or casting settings. Make sure the casting device is set to the correct brightness.
