If the USB ports cannot work properly on the Mi TV 4 32, 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. Sometimes, a simple reboot can resolve minor issues. Please turn off the TV and unplug it from the power source for a few minutes. Then, plug it back in and turn it on;
3. Carefully examine the USB port on your TV for any physical damage, debris, or foreign objects that might obstruct the connection. If you notice any issues, you may need to clean or repair the port;
4. Try connecting your USB device to different USB ports to see if the problem persists. This can help determine if the issue is with a specific port;
5. Ensure that your TV has the latest software updates installed by going to [Settings] >> [Device Preferences] >> [About] >> [System update] and check for updates;
6. As a last resort, consider performing a factory reset on your TV by going to [Settings] >> [Device Preferences] >> [Reset]. This will erase all the data on your TV, so make sure to back up important data before proceeding.
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.
