If the USB ports can’t function properly on the Xiaomi TV A Pro 50, please refer to the following steps:
1. Ensure that the USB device you're trying to connect (e.g., USB drive, external hard drive, or other peripherals) is working properly. Try connecting it to another device to confirm that it's not the USB device causing the issue;
2. Carefully examine the USB port on your TV for any physical damage, debris, or foreign objects that might be obstructing the connection;
3. Turn off the TV and unplug it from the power source for a few minutes. Then, plug it back in and turn it on;
4. The TV has two USB ports. Try connecting your USB device to different ports to see if the problem persists;
5. Ensure that your TV's firmware is up to date. You can check for updates in the TV's settings menu by navigating to [Settings] >> [System] >> [About] >> [System update];
6. If all else fails, please reset your TV to the factory defaults by going to [Settings] >> [System] >> [About] >> [Reset] >> [Factory reset]. Keep in mind that this will erase all data and settings on the TV.
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.
