wont turn on /blinking red led

[Space_pilot]

Hi all, have my xperia z3 for about two weeks, not rooted, not unlocked, without any modifications. Yesterday before sleep it was with more than a half of akku, today as im woke up and got it in my hands it was off, im plugged charging cable, was thinking maybe the battery was drained, but nothing happens still, its just blinking red (led).
Was trying to hold power + volume up, nothing.
Reset key near sim dont works for me either - i'm just notice 3x vibrations and thats it, its just repeat vibrate 3x times again and again but nothing happens, no boot.

?

You may need to perform a software repair using PC companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% 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).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

Trying to do so, (Assistent is asking me to connect it with volume down key but seems not seeing my phone) nothing happens, its just keeps blinking red, maybe its not fully charged, but its ready 2h connected to charger. Im not sure if its even charging cose all what i can see its red blinking led. Will wait 2h more...

P.S. 3x vibrations i can get only with a key that is near sim slot, power +volume up dont works - no vibrations.

Also make sure it is completely turned off by pressing power button and volume up at the same time or by pressing the small button.

Sadly its not working. To replycate my steps: im put it off by pressing powerbutton + small button near sim, i get 3x vibrations so its off, than waiting enough (more than 5 sec), connecting it with cable that is ready on my leptop by pressing volume down button at the same time as im promted by PC Companyon, nothing happens , the only led starting blinking.

Im thinking its not on its just always off and simply cant start, something with battery maybe.

P.S. Should i contact O2, its where i bought this phone, and send to repair?

I'd had the same problem and tried the same steps to revive my xperia, today I sent it to Sony and the support has said their lab is going to see what problem it has.

Sony is the worst company , their phones have a short life span , Do not buy!!
