What to do if the Xiaomi TV A Pro 55 can not be powered off via the remote control?

If the Xiaomi TV A Pro 55 can't be powered off via the remote control, please refer to the following troubleshooting steps:  
1. Ensure that the remote control is functioning properly. Check the batteries in the remote control. If they are low or depleted, replace them with new ones;
2. Please make sure there are no obstructions between the remote and the device. Obstacles sometimes interfere with the remote control's signal, preventing the remote control from shutting down the TV;
3. Please make sure that the buttons on the remote control are not stuck. If the power on/off button of the remote control is stuck, the TV cannot be powered off using the remote control;
4. Please ensure that you are using the original remote control that came with the TV. Sometimes, third-party remotes may not work properly;
5. If there are other devices connected to the TV, such as external hard drives, unplug them and attempt to power off the TV;
6. You can force your TV to turn off by unplugging its power cord;
7. You can check for system updates by going to [Settings] >> [System] >> [About] >> [System update]. If it is the latest version, a message will appear on the screen indicating that your system is up to date;
8. If other troubleshooting steps do not resolve the issue, you can consider performing a factory reset. Please go to [Settings] >> [System] >> [About] >> [Reset]. Please note that the operation will erase all data on the TV, so be sure to back up important information 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.
