Xiaomi Mi 8 Lite - can't turn on and no reaction
Client brought a broken Xiaomi device few days ago telling that it got stuck during alarm clock. Somehow he turned it off and never turned on again.I’ve disassembled the device, removed the battery and replaced it with “hot power supply” at 4.1V. After pressing the power button the device starts to drain >200mA of current to immediately drop to ~90mA. No vibration occur, no backlight, no image on screen. I’ve checked for water damage, physical damage and measured capacitors (those, which were able to reach due to the permanent shield mounting), and everything seems fine.
Has anyone got any suggestion what should I do next? Or it’s just now meant to be a brick-phone?
Edit: Screen seems to be fine. No cracks and no leaks.
Is this a good question?
