Based on what you say, it appears the logic board was damaged. The iPad should boot up without an LCD and Digitizer so if it is not being recognized by iTunes, then the issue is most certainly on the logic board (check you cable and computer with another device just to be certain). It’s very important to isolate the battery from the logic board when doing repairs. The typical issue is usually the backlight circuit but just about anything can go sideways.
