Hi,
My Sony Xperia Z4 Tablet has these problems:
- No connection to PC > Nothing happens. (Only connection beep, nothing else. I tried Vol.Down or Up then USB etc.)
- Connecting to USB charger > Nothing happens.
When Powered OFF:
- Connecting to USB charger > Vibration, Red and Green flashes but nothing happens.
- Power button + Vol. Up > Vibration, Red and Green flashes but nothing happens.
- Forced Shut Down (Memory card slot OFF button for 120sec) > Vibration, Red and Green flashes but nothing happens.
RARELY after repeatedly Force Shut Down "Vibration, Red and Green flashes" these happens RANDOMLY:
- Red LED lights up and charging very-very slowly (2 days ~ 23%) (In this case the upper right quarter of the tablet is warmer.)
- Red LED lights up but NOT charging at all.
- Red LED lights up, display is black and backlight dimly lit but NOT charging at all.
Any suggestions?
Thanks in advance!
