① You can try restoring the device to factory settings to see if it helps.

② Check the device’s firmware version. Older firmware versions can be updated to the latest version.(Note: If it’s not an official program, always upgrade to the official version regardless of the date.)

③ if you have a computer, you can directly connect the device to the computer’s network port with an Ethernet cable. After restarting the device, try accessing the device’s lP address directly from the computer to see if the device’s image is displayed properly.
