Xperia Z not powering on

Hi i have a sony xperia z that just doesn't want to power on when it's plugged into the charge the red led appears however that red led goes off after it's been in the charge in around half an hour of it charging it doesn't get recognised by the pc by flashtool or sus or pc companion not any hard reset or any of that work such as vol up + power and vol down + power or vol up + plugging usb in even if i hold the buttons for around 5 minute nothing happens, this phone isn't water damaged as all the indicators are white

Connect to pc's usb and leave it for some times.
And maybe you can explain more what you was doing before it happens like this.

i have connected to the pc and i also left it for more then an hour just when i first connect it to the pc it has a red led but later on that red led comes off and i honestly don't know i bought this phone in this state

I had the phone connected to the pc and that red led went off for a bit then it came back on

Are you using the original charger?

yes i tried multiple chargers aswell

i heard about dead xperias without reasons(in most of cases they turned off the phone and it never turn on again) maybe is better if you take it to a centre

Could it be the battery by any chance

Help?

hold down the volume up and power button for 10 seconds, it reboots the phone
let me no if it works

Try what Andy194 said. Falling that try speaking to Sony themselves. Mine did that and they offered me a warranty replacement. Luckily the problem solved itself. As I was about to put it back in its box and send it off, it suddenly booted up fine, on its own.

My Z refused to charge when it was on 1%, as if its conntact with usb cable is not working well, happened once already but it returned to normal. So I decided to turn it off as it would turn itself off anyway. Plugged it in, but it didn't work. Used my Arc's cable and the red led light came up. I waited a bit for the phone to boot up to get to the charging animation, but nothing happened so I plugged it out and to my surprise the red light didn't go off and I can't do anything to turn it on. The phone is just rooted to 4.2.2, BL is locked.

Edit: left it plugged in my laptop and after 15 minutes or so it powered up. Yay T-T

[HELP] Xperia Z brick?

hi,
sorry for my bad English,
I bought Xperia With a damaged touch. The phone is normally turn on. the touch did not work. I decided to take himself for the replacement of touch (glued to the LCD). I disassembly phone . before removing the motherboard still plugged in the battery to see if the battery will not hurt the dismantling of the display, the phone is turned saw the Sony logo and disconnected the battery (do not know if it was a good idea). After removing all nicely warmed the screen and slowly removing pieces touch. Unfortunately, at the end it turned out that a little too much it warmed, because the screen began to appear discolored, so were pissed, I ordered a new display and in the meantime, as I wait for the touch I wanted to see if it works. I have connected to the display board, tape, buttons and battery. Turned on, the phone vibrated and enough black screen. So I stitched it to "poop" and I wanted to run, but it was all the same. Computer can not detect, etc.. After some time, as it was plugged into usb turn on the red light. Ive loaded software program SUS, and after you press the power button flashing red LED 3 times. I left the phone on the charger overnight from nokia (1200mA), but it does not improve, after that, that when you try to turn the vibration and again, so much. The phone is detected in fastboot mode (blue LED) and flash (theoretically green), because as I press the phone turned off and hold down my Vol- is a second red LED will flash immediately changes to green and then turns off the computer recognizes the phone as SOMC Flash Device (SEMC not SOMC) and in this mode for the update service is normally upload the software to the end, in the Flashtool the same situation. I do not know if it's important, but after every uploading the software when you try to turn this unfortunate flashes red LED 3 times as if the battery is discharged. Could this be a defective battery? Phone before you got in my hands was lying unused for some time. How it got it it plugged into the car charger (840mA) for around 40min +/- and normally work. I do not remember whether if it was on some LED.

Why could you buy a Xperia Z with damaged touch? And why you try to repair it yourself?

If battery was working properly before the experiment that you did there must be something wrong that you must have did.
Try a different battery and see whether it solves issue or else you must have damage the mo-bo

My Xperia dead after remove battery.
Stuck in flash mode.
Fastboot and flash mode works. (Blue and green led)
unbrick from flashtool?

[Q] sony xperia T10 wont turn on, flashes red

Hi.
so the thing is, that even some time before this happened my xperia T10 was restarting while not connected to the charger.
I couldnt use it daily because it just kept restarting whenever somebody called me or I used the mobile internet.
Few days ago I left my phone without charger for night and I believe it kept restarting over and over again.
When I woke up, I couldnt turn it on, when its not connected to the charger it simply flashes red 2 times and thats it, if connected it flashes still red light as long as I press power button.
I thought its the same problem like I had with a tablet long time ago and it would be enough to let it charge for 2 days or so.
its 3rd day now and everything is still the same.
What should I do?
I dont have an acces to PC or laptops since I dont have one.
Any advice?

Bump up

I opened the case and took the battery off for few hours and then put it in again, and ofc i attached all the cables and such back again.
Now when i hold volume down button and power button the led turns green for 5 secs and then fades. Then whenever i push power button the red led flashes still light but it dissapears after 10-30 sec and comes up again after few seconds.
help...

I know this from my xperia T. I hold (in holder not in my hand) the power button for long time (about hour) with connected power cable. And after this time it starts work. Try that

xperia sp doesn't turn on and red led blinking

Hi guys my xsp has gone to sleep since 2 days ago. it had low battery percentage and it was in my bag. i just pick that and tried to turn it on. nothing happened. i thought it is out of charge and I plugged it in for many hours but i didn't see any signs of charging ( led or turning on. red led turns on after some minutes and turns off again) and when i removed the charger and tried to turn it on the red led blinked for 2 times for each power button pressing and no signs of turning on! i tried both yellow button in the back and volume up + power and also setting in charge for long hours. no changes! plz help
you can see video from this link https://files.fm/u/47qk6fxj

you can try jumpstarting your battery (requires a bit of disassembly), and if it still doesnt take a charge the battery protection IC (it should be part of the battery, it usually is) is bad, and you will need to replace battery.
good luck
