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

any ideas. ??? ive ruled out the charger and the cable already.

Sounds like it might be hardware related, the USB connector in the phone might be damaged. In that case you should send in the phone to a service center for repair. Contact your local Xperia support for more information. See my signature for contact info.

I plugged it into the wall charger and it booted.
So looks like battery out repair by the computer worked for me. At least on my Z C6603

Hi @omdavice @wantboost

When turn on the sony only the red led light flashed multiple times. This could be because battery was fully drained or there
was a problem with the boot. If you press the 3 buttons Power, Volume down and Volume up for about 8 seconds and then release them, the sony logo would appear.

If this doesn´t work, you can also first run a backup of the device information like this:

Then try performing a system repair using PC Companion:

http://support.sonymobile.com/gb/tools/pc-companion/

This will factory reset your phone and erase all data. You might need tocharge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process. If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP.

I hope can be useful.

Hi @wantboost

Try a system repair or booting into Flashmode. Switch off your phone, hold volume down and connect the usb cable. If your computer detects a connection, then your usb port is ok.

I hope can be useful.

I encountered the same situation from 3days  Impossible to switch on, no light, no effect with charger, no effect when connected to PC

Hi @amigo11

I suggesto you connect your device to a wall charger and then press and hold power & volume up for more than 10 seconds. Let it charge for 2 to 3 hours, even if it doesn't seem to be charging.

You can try by plugging the usb cable as you hold volume down too.

Also if when you turn on the Sony device only the red led light flashed multiple times, this could be because battery was fully drained or there was a problem with the boot. If you press the 3 buttons Power, Volume down and Volume up for about 8 seconds and then release them, the Sony logo would appear.

I hope can be useful.

I'm at disposal for any question.

Best Regards,
