What to do if the Xiaomi TV A 65 2025 cannot adjust brightness or contrast?

If you cannot adjust the brightness or contrast on your TV, 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. Clear the APP's data or cache in settings;
2. Check for updates for the APPs installed on your TV. An outdated APP can cause compatibility issues;
3. If clearing cache and data doesn't work, you can uninstall it and then reinstall it from the Google Play Store.
Scenario 2:
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. Ensure that the HDMI cable connecting the external device to the TV is in good condition. Try using a different HDMI cable to rule out any cable-related issues;
2. Ensure that the external device is configured correctly. Check the settings on the external device to see if there are options related to brightness and contrast.
Scenario 3:
If the issue occurs when you are using casting on your TV, please refer to the following methods:
1. Make sure that both your casting device and the TV are connected to the same Wi-Fi network;
2. On your casting device, check the screen mirroring or casting settings. Make sure you have selected the correct TV or casting device;
3. Please adjust the Picture mode on the TV and see which one can resolve the issues;
4. You can also make corresponding picture settings to adjust brightness or contrast;
5. Check for available updates for the system;
6. 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.
If the above troubleshooting methods can’t resolve the issue, please contact the local after-sales service center for further assistance.
