Earlier today my phone fell onto a carpet - and when I went to check the phone, it was still on, but the screen was completely black even if I hit the power button. The screen occasionally flashed, as if the backlight was trying to turn on, but only for a second. Even I boot, the screen is black BUT the backlight is on then. There is NO boot logo. There is no bootloader even if I hold X. It's just a black screen. Is there anything I can do?
