What to do if the screen of the Xiaomi TV A 65 2025 dims or glows abnormally?

If the screen dims or glows abnormally, please refer to the following scenarios and their troubleshooting methods:
Scenarios 1:
To check the TV, please refer to the following methods:
1. You can check for the brightness, contrast, and other display settings;
2. You can check for the available updates for the system;
3. If the issue persists, you can consider performing a factory reset. Be aware that this will erase all data and settings on your TV, so make sure to back up anything important before doing this.
Scenarios 2:
If the issue occurs when you are using APPs on your TV, please refer to the following methods:
1. Clear the cache or data of the APP in Settings;
2. Check for updates for the APPs installed on your TV. An outdated app can cause compatibility issues;
3. Check if the videos that you are playing are dim.
Scenario 3: 
If the issue occurs when you are using an external device like a 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. If you're using external devices, like a cable box or gaming console, ensure that the HDMI or other cable connections are secure and functioning properly. Faulty connections might cause display abnormalities;
3. If the issue is related to an external device, check for firmware updates for that device.
Scenario 4: 
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. 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 resolution and aspect ratio.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
