Lenovo S8-50 screen is unresponsive

[AC Question]

The screen on my Lenovo S8-50 tablet has become unresponsive, even after carrying out a factory reset.
Unlike on some other Lenovo models, the recovery menu does not feature a screen calibration option. With the screen inoperable, I am unable to use USB debugging mode to see if a calibration option exists within Smart Assistant.

Does anyone have a possible solution?
