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

bump

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

[Q] Unable To Turn My Xperia Z On!

Hey guys, got an Xperia Z c6603, unlocked bootloader, flashed Paranoid Android and have been running fine ever since. However, last night while in use the phone just went black. I can't turn it on, when holding the power button I get the LED in the top right corner flashing red 3 times. It won't seem to take a charge either.
Things I've tried;
Power Button + Volume Up (No Response)
Power Button Holding (Red LED flashes 3 times)
Power Button + Volume Down (No Response)
Connecting to charger (sometimes the LED flashes red once for a moment and then turns off)
All the above combinations while plugging into charger (No Response)
Connecting to PC (Same as above and Windows won't detect it)
Trying to enter Flash mode and Fastboot mode (No Response)
Anything I can do to revive my Xperia Z? It seems to me like the battery is almost completely discharged. Already sick of returning to an iPhone after having a great eXperiance so far
Any attempt at help is appreciated!

Hmmm, I think something might be wrong with either your motherboard or the on/off button. I'm pretty sure it's not a battery related problem in terms of it being almost dead. I've got my XZ since Feb 28 2013 and my phone still survives for days.
I don't know how long you've got your phone, but it might be time for a repair center, since there isn't really much you can do. Especially since the phone isn't being recognized by Windows anymore.

I got a few red led blinks in the past but i fixed it after charging (just pluged the charged and booted fine)
Try to leave it on charger or wall charged for 1 day and see

[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?

XSP won't charge or boot

Hi
I am stuck with a phone that won't boot, charge, or be detected by flashtool (or windows) and will not boot in flashmode/fastboot either.
I had plugged in the phone for charging when the battery was considerably low ~ 5-10% before I went to sleep. I remember the red LED glowing, meaning the phone must've been charging.
The next morning I check the phone, the LED was STILL red and the handset was kind of dead - no response at all, whatsoever. Even the reset button on the bacl panel doesn't work (no vibration).
The phone was running BlissPop (5.1.1) with Tangerine kernel.
Now when I plug in the phone for charging, nothing happens at all, not even the red LED. The LED does glow red for as long as I press and hold the power button while it is plugged in (both PC and wall outlet)
I took it to the service center; they say they'll have to change the motherboard. Obviously the phone is not in warranty and there is no way I can pay 10,000 INR that Sony is demanding for the job.
Someone somewhere in the forums suggested allowing the battery to drain completely, but I don't think my battery is holding any charge.
Can anyone help me out?
Thanks

1. Press and hold the reset button for 8 seconds and check if it vibrates. Now plug in charger as there is a possibility that phone is not booting because of insufficient charge.
2. Charge for atleast 20 min without switching on phone.
3. Make sure flashtool is installed properly and so as drivers.
4. Flash Stock ftf
If the above didnt work then try Fastboot mode and simply flash Tangerine kernel.
If nothing works, then its an hardware issue and there is no point in spending 10k in repairing.
Get yourself a brand new Moto G or yureka.

http://forum.xda-developers.com/showthread.php?t=2717303 <- this guy had a pretty similar problem and managed to fix it
I was following the steps he provided: i plugged the phone to PC and held the power button pressed. Surprisingly the PC did recognize the phone after a while- but it was only momentarily and the red LED also stopped glowing. Unfortunately I haven't been able to reproduce a similar situation after that.

Xperia T - stock, not rooted potentially reversed USB connection, now won't switch on

Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks

Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken

Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:

When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!

SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!
