[Q] Xperia Z Strange chargins issue

[dinesh17]

I replaced my broken screen recently, the battery had been lying dead for more than a month. Now after replacing the screen when i try to charge the phone, the RED LED blinks on a frequency of 7-10 seconds.
When I disconnect the battery flex and connect it to my PC it goes to fastboot mode, I was even able to flash a stock rom. When I connect it to main charger with the battery disconnected, display shows sony and turns off.
When reconnect the battery it won't display anything and the RED LED keeps blinking frequently. What might be the problem faulty battery ? or main board problem ?

The battery is completely discharged. Keep it on the wallcharger for 24 hours and then try to boot it.

But if it is discharged completely and when tried to recharge why would the red led keep blinking and not continuously glowing ?

It is not unusual. Just wait and you will see that it comes back on

Now the battery is charging I guess, RED LED is now glowing constantly which has been blinking earlier. Even though I was not able to Switch it ON.

The only way to recharge the phone is by using charging dock
