Mengapa handphone saya mesinnya hidup tapi layarnya tidak menyala

Handphone saya awalnya jatuh dan pecah LCD, lalu saya ganti LCD baru, tapi tetap tidak mau menyala, tetapi bisa di sentuh walaupun posisi layar tidak hidup

Translation Indonesian - English

Why is my cellphone engine on but the screen is not on? My cellphone initially fell and the LCD broke, then I replaced the new LCD, but it still wouldn't turn on, but it could be touched even though the screen was not on
