[Q] Xperiaj J many issues.....

Hello,
I recently bought Sony XPERIA J which accidently slipped into water tank which with no doubts remove the warrant of My phone & have caused several issues with its working. I kept the phone switched OFF for 5 days and successfully removed moisture from its motherboard. When I turned it ON everything is fine except malfunctioning of WiFi & several Touch Screen issues.
1. The problem with Touch is that whenever I press the POWER KEY to unlock phone I have to wait for atleast 5-10 sec for TOUCH to start responding. Is this a software issue or is it a hardware and also is there any way to fix it.?
2. Another problem is the small LED light (notification indicator), it is constantly glowing BLUE and does not show any other color for any notification and even never turns OFF. Can it be fixed?
3. Problen with WiFi is that it just keeps on trying to turn itself ON with no success, which is consuming the Battery Power a lot. How can I turn OFF the WiFi permanently?

Dude, those are clearly hardware issues. There's no way we can help you with that... take it to a repair store or try your luck with the official warranty.

Thanks for Your reply.
I actually took it to the sevice centre but the said it can only be fixed by replacing the motherboard which costs Rs10000/- , so I just thought of asking for help over here.
Alright, I can bare with these TOUCH & LED issue, but I really need to disable WiFi, so is there any way to do it like removing WiFi module or something like that?
you can try and say to the service centre officials that it started happening after u tried to update but it failed...ofcourse you have to find another service centre
just prove this is happening due to software reason even though it isnt
As they say, bring it to a Sony care point.

I have exactly the same problem with my Sony Xperia Z3 Dual that I bought today 1 year ago.
I got a new screen 4-5 months ago as warranty to repair this problem and now it is coming back again. Seems to me that there is a mistake in the design somehow if it appears again in the same way
I googled and I didn't find anything particular about it, apart from changing the screen with the warranty and doesn't look like a common issue for many.
As my warranty expires today most probably I cannot do this trick again and even if I do how can I make sure it doesn't come back again?
Has anyone any idea of this problem? What causes it?

xperia z3 no screen backlight! then screen dead!

I've a problem with my new sony product, I was in swimming pool after taking some photos the phone stop working, and the screen blinking and can not boot up the phone, after checking it I notice that there is some water in the back camera cover.
So i waited about 5 hours and tried to recharge it, then trying to boot it I heard the startup sound with no data on the screen!
I noticed that the screen/touch working but there's no back-light!
then I shuttled it down and wait again, after booting the screen has no data and the startup sound works, ( Also there is no vibration anymore! )
I tried to use the small off button but no way! I've also upgraded it via PC Companion but still have the same issue!!
I don't know what to do the phone is new I bought it from another country so its international warranty! the the xperia care here in Egypt is too disappoint.
Please help!
I'm sorry to say, but the service centre is your only option. U might wait more because it's international warranty, but since the dead screen was caused by a faulty water resistance they should replace it for free

What ??
When phone boots up it gets as far as the android 'welcome - lets get started' screen. The touch screen is unresponsive so i can't select 'lets get stated' the after a few seconds it reboots going into same cycle.
Vodafone said it was the screen however after a replacement screen it is still not resolved. I've tried software fix through phone pc companion but no luck.
Vodafone won't look at it again so I'm stuck with it.
I just wondered if anyone had a similar problem and if it easy a fault with a small component that could easily be replaced.

Sony xperia z3 d6653 screen problem

Hi, guys im having a problem with my z3 sometimes it only vibrates but doesnt turn on, sometimes it doesnt go past sony logo turns off and sometimes it turns on.. My z3s screen used to flicker from time to time so I thought of buying a new screen but I just canceled my order as I thought if it shows the sony xperia text its not a screen thing, idk if its software related cos when *rarely* it boots I can use it normally. I have its back cover opened whenever I try to turn it on there is a noise on the motherboard (dunno if its normal) if any of you have any suggestions you are welcomed!
My d6603 has the same issue (flickering,all that u mentioned above),have you managed to fix it pls tell me how....( Cant use flashtool for rom flashing)
Unfortunately no, I concluded its a motherboard issue so im looking for a new one...
