Not heard of this before. I'm guessing the backlights on the three silver menu buttons at the bottom of the screen don't light up either.
As a first step I'd just charge the battery for approx 12 hours/over night as after any storage the phone probably needs a good charge.
Given you have had the phone operational now for a while and probably a few charges, has the back-lighting now restored it's self??

Another problem with battery of xperia sk17i

Sorry for open a new thread in forum, but i didn't find no topic which talk about that problem of mine.
Some days ago i installed applications from play store on my device. The battery was 30% while i downloaded app and install them. Sooo, i downloaded and installed some apps, until battery was 1%, and i powered off the device, and i was want to put it to charge...i charged that until had 100% power, (i was put that to charge to 23 a clock - pm, and i was pull out to 6 a clock - am). And i tryed to power on, and the green led blink very short, after that vibrate but, don't show to me nothing on display. I know is anormal to blink that led green, and also i knew he must show sony or sony ericsson (the brand) after vibrate...but only vibrate, and that's all..............I dont have any idea, where to be the problem...Pls help me, and also, sorry for my english. Thanks a lot!

and i forgot to say that, i tryed to install a news firmware, and to i leaved battery out from phone 2 days...but no change...is same - black
So, when you try to turn on your device, green LED blinks, phone vibrates and that's it?
What happens if you plug in the charger? Does reinstalling the firmware(Flashtool or Update Service) fix the issue?
What ROM/Kernel did you have? If stock, rooted or not? Any modifications?
Also, wrong section to post it.

no, is doesn't fix the issue no firmware; i tryed with Update Service also flashtool, and still the same. When i plug the charger, show me is completely charged (the led - green) but dont show to me nothing on display. When i connect it on the usb in pc, the led remain green.
Rom is the last one from SEUS, i dont know to say the model, but anyway, i tryed not only that, also all i founded compatible for my model. Without root. I know normally is to dont blink any short led when is power on...

looks like hardware problem. check the battery by putting it into someone else mobile.
What firmware did you have last, when phone was still working?
Was your bootloader unlocked or not?
My next idea is warranty service.

[Q] Xperia Neo L not switching on

Hi,
I have been using xperia neo L for quite some time now. I have not faced any problems with it till last week.
My phone got switched off suddenly and it went on restarting continuously.
It switches on shows sony logo and then logo of xperia and it again restarts.
I then reinstalled my phone using the update service.
My phone worked fine again for 2-3 days.
After that again the same thing happened,suddenly got switched off and it gets restarted.
This time logo of sony appears, after that immediately it gets restarted.
So again I did the same thing, i.e reinstalling,worked well again for 2-3 days, after that same problem happened.
This time I cannot hear the vibration while switching on and no logo appears.In fact its not switching on at all.
Red light that blinks while connecting the charger is also not shown
I cant even try for a reinstall this time since while connecting the USB and holding the back key no response is being shown.
Can somebody please help me out??
Since i dont have warranty for the phone, can somebody let me know what the real problem is and how can I fix it??

If your LED doesn't blinks while connecting phone to computer, then there is a chance that battery might have drained out... Blindly charge for an hour.. Press and hold the 'back' button on your phone... Then try flashing the phone... All will be good if LEDs work fine... Else it'a hard brick... If flashing is not working out for you, then you need to go to customer care... Suppose if the phone works now and if you are not rooted and your bootloader is unlocked, then I recommend you to root... Sony Official ICS is not that smooth on Neo L... So root, unlock bootloader because anyway you are out of your warranty... Then install custom kernel ROM.. There are so many custom ROMs for Neo L... Good luck...

[Q] XP charge light stuck

Hello, I have a problem with my Xperia P charge light, it stays lit even after removing the charge cable. It also still says it's charging in the Android OS. I have Moonwalker 7.5 ROM, it also happened on stock 4.1.2 0.400 and 1.100.
Can someone shed some light on this?

Its normal !!
Just turn your screen on and off and its gone.
Its not only with my rom but every romas you can see by your own.
Ask Sony to solve it.

Turning the screen on/off doesn't fix it, it disappears after a while only

So why doesn't it happen on my phone, mostly stock?
Baterry stats change immediately to not charging and led turns off if screen is on, if screen is off takes it few seconds to turn off.

So it might be a hardware issue at my side? Can anyone else confirm it doesn't happen on other Xperia Ps?
@ChikeD he mentioned it was on stock also so its Sony's problem. I have it but after turning on the screen it went away

Have you installed any apps that control the notification led such as light flow? If thats the case, try delete that app and see if the problem persist

Sony Z5C in bootloop - Red LED flashing 4 times *edit only no screen

Hi all,
A while ago the back of my Sony Xperia Z5 Compact had a big crack. Since I was opening my phone to fix this anyway, I decided to replace the battery + ribbon cable for the side buttons and vibrating motor as well.
All seemed good when I deassembled it and put it all back together. Unfortunately my phone hasn't booted since.
When booting, the backlight lits but I see nothing on the LCD. I get a blinking red LED for 4 times, after which it stays solid red for a little while followed by a reboot.
Somewhere on the internet I found that the 4 flashes represent a defective LCD, although I have no verification of this.
What I've tried so far:
All the possibilities given on the internet using the volume up/down/power button.
Using the off button near the sim tray (10 sec pressed / 120 sec pressed)
Used the repair function of the Sony Xperia Companion (which succeeded without any result)
Changing ROM / Kernel using flashtool after unlocking the bootloader
Using the old battery to see if this makes any difference
Measuring the L fuse, which seems to be fine.
Charging my phone for many hours
Unfortunately non of this seems to work and I'm out of options. All was working fine before. Also the new battery gives 3.8 Volt and the ribbon cable with the new buttons works.
I can get my phone into fastboot / flash mode
Does anyone know what else I can try, or is it a defective motherboard and is it time to say goodbye to my z5c?
I hope someone can help me out
Update:
I flashed another rom (nougat 7.11 ) and used greenkernel. Now the phone stops flashing red. The battery shows its normal green (fully charged) LED.
Unfortunately still only backlight and no LCD.
Hey QuuN,
I got the exact same problem, and tried exactly what you tried, including measuring the L fuse (and it was normal).
I would just like to know if you finally achieve to repair it.
I hope you are doing well in these times of pandemic crisis.

Hello Destruktanc,
Unfortunately I wasn't able to fix the problem. As it was an older phone, the costs for replacing the motherboard / LCD wasn't worth it for me.
Hopefully there is an other solution for you which doesn't involve replacing hardware. As for the pandemic crisis, I'm doing great. Hope that also goes for you.
