If the Xiaomi TV lags after running for a while, please refer to the following methods for troubleshooting:
1. Check whether the TV is overheating due to prolonged operation or excessive ambient heat. Try putting the TV in no-operation status for a while. Ensure it is placed in a well-ventilated and room-temperature environment.
2. Please restart the TV to clear the temporary cache and free up memory.
3. If there are too many App caches, the system will lag. Please clear the App caches.
4. Please check whether there is an available system update and update it in time.
5. If the TV still lags, reset the TV and check whether the problem persists. Resetting the TV will clear all data, so please consider this before proceeding with this step.
6. If the above methods cannot solve the problem, please apply for professional after-sales inspection.
