Sony Xperia Z - Dead, won't turn on, won't charge, PC doesn't recognise

[fundars]

Hi there

Bought an Xperia Z about a month ago. Had slight lag issues but nothing too serious.

My phone ran down and the battery died two days ago. I put it on the charge (its been on the charge pretty much ever since) with the red LED lit up. LED turns off completely when unplugged.

Phone will not turn on at all; have tried all of the manual resets (holding power button and volume button etc); have read these forums and searched the web for a solution to no avail. PC doesn't recognise the phone so can't reset it via PC Companion. Basically, I have an $800 unresponsive brick.

Very very disappointed to say the least. Phone was very well looked after, and to have it die simply because the battery ran down is extremely worrying. I've seen that this issue is very common yet there doesn't seem to be any definitive fix for it whatsoever.

Any help that anyone can give me would be really appreciated

I will just add another unanswered question, but it at least feels good to do so.

My screen had a shock and got it replaced. Got my phone back and no way to turn it on.

It is very strange :

-If I plug it to my computer the blue light appears and I can hear the typical Windows USB recognition and nothing happen. PC Companion never finds the phone.

-When I plug it normally to 220v (with original cable) that's where it gets odd. The red light appears about 1 or 2 seconds. The Sony appears on the screen and phone vibrates. Red light goes dead straignt after vibration and screen goes black. Then the red lights come again for a few second, and same again Sony on the screen a few seconds... and so on... It goes on a loop but never charges and no way to switch it on.

No clue of what it could be...

Help would be appreciated even if I have not much hope.

Have you tried this yet?

My Z3 would not power up and no charge LED when cable plugged in. Finally found this solution on Sonymobile support website which fixed my phone!

To force the device to restart

Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") until the device has emitted three vibrations, and then release the OFF button. The device turns off automatically.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
If a forced restart procedure as described above doesn't succeed in turning on your device, you should try another kind of forced restart - the 2-minute restart procedure.

To force a 2-minute restart

Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") for 120 seconds (ignoring any vibrations), and then release the OFF button.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.

I had to hold the 'off' button for about 60 seconds before the phone vibrated and sprung into life - phew!

Having the same problem.

let your phone charge for a couple of hours as the slow flashing red light while charging means that your battery is completly dead.

then take off charge.

to reboot, first hold down the power button and whille holding it, press and hold down the volume up button until you feel 1 short sharp vibration. release both buttons and as soon as you do, it should reboot.

reboot wont work if you get to 3 vibrationsits which comes after the one short sharp vibation.

the reboot should turn your phone on using safe mode..... im still working on how to get it out of safe mode....

very important to remember to hold the power button first, and while holding it, press and hold down the volume up button.

dont press and hold down the power button and the volume up button simultaneously, the reboot wont work.

What to do...?

But the phone is not connected by pc

That's fine, even though the PC cannot see the device, you should still be able to go through the repair process.

Hey I have the exact same problem. How did you fix your phone?

[Orange_123]

Please try a 2amp charger with a smaller USB wire.

Your charging problem will be solved.

Thanks
