Hello, thank you for your reply. You can try the following methods to see if it helps you.
- Connect the power adapter. When the device is turned on or off, press and hold the power button for 30 seconds. Release the power button after the power light flashes, disconnect the adapter, wait for 3 seconds, re-plug the power adapter, and then press the power button to turn on the device to check if it can return to normal.
If the above method does not work, I will ask after-sales service to contact you. Thank you.
