Short answer: A dark screen may reflect low charge, display settings, or a fault. Check the manual and battery indicator for your exact model before assuming a repair is needed.
Simple checks
Confirm the packaging film has been removed as directed. If the model supports recharging, follow the maker’s charging instructions while present. Check whether its manual describes a screen sleep or lock mode.
Stop using if damaged
If the device is hot, leaking, swollen, damaged, or behaves unexpectedly, disconnect it if safe and contact the seller or manufacturer. Do not open a sealed battery housing or try undocumented button combinations.
For battery precautions, see the FDA battery safety guidance. Follow the instructions for your exact device.

Does a black screen mean the liquid is empty?
