Strange issue... Does your Z2 ask you for a PIN code when you turn it on or not?

"also in some locations it has signal but manly it don`t" --> unfortunately this feels like an hardware problem, defective or disconnected antenna or something like that.
If it was software related flashing the stock rom should have fixed it...
Have you tried another sim card on your phone? maybe a defective sim card could be the cause too and you can test that easily. if it's also not sim card related i would send it to sony if i still had warranty.
If i was out of warranty i would open the phone (buy new adhesives before you do this, i don't think you can reuse the original) and check the coax antenna cable. I never opened my z2 but it doesn't look that hard.

on step 6 you can see the coaxial antenna highlighted in the blue circle, it looks like a pigtail connects it to the motherboard i would check that first.

I'm not an hardware expert but if it's not the sim and you're seeing some water damage inside the phone that's probably the cause. you might have water residue or oxidation on the antenna connectors which will make your signal weak. you can buy a new antenna online cheap and replacing it looks very easy. after a quick search i found this: http://www.witrigs.com/antenna-rf-cable-for-sony-xperia-z2
I really like my z2 and i would try everything that was not too expensive/hard to fix it

Problems with SGS3 - how to read logs?

Hello,
My friend has problems with her SGS3. It's about 1 year old and it started restarting and turning off itself. Sometimes it's on a keypress, sometimes while charging and something it just went off without touching anything. She sent it to repair and they said that there is some damage on motherboard from water (but it was never wet so it's weird) and it's glass is broken (it felt on the floor and broke a few days after buying), but the screen and touch digitizer work fine.
Since the repair is more expensive than new device, she wants to check if there is some software problems before giving it to someone who can try to fix it. The phone is not rooted, so is there any easy way to check its logs (some app or something)? Is it even possible without rooting?
In case of hardware problems, what should she do now? If the mainboard is broken and the glass is broken too, it's almost impossible to sell it for parts because only battery and soem minor parts are usable. Is it worth repairing the motherboard?

Isn't that the USB port? Looks like it's already fried. From the looks of it, the service center is right it's a hardware problem and for them to say that the motherboard is broken probably means other components are also fried. In my opinion it's better to buy a new phone as a repairing it outside warranty is much more costly than buying of a new phone.

Yes, it looks like USB port. Maybe something is fried, but the phone works so all chips and electronics must be okay. They said that there is corrosion on the motherboard. The phone was never wet but it can be due to condensation or humidity. I have a friend who told me that he can fix it if there is only little corrosion, but before trying, I would like to take a look on logs if there is some software problems. Another friend told me to wipe and flash original kernel and ROM from fresh, but I don't think that this is a smart move since the port could be broken and we could brick the device if it lose connection during flashing.

I see... so the phone still works. That type of damage is probabaly because of humidity like what you suspect. In my opinion further use of the phone with an existing hardware problem can lead to a more bigger problem so no logs can be of help here. That fried usb port can also hinder on flashing a new rom like what you said as it may fail during the flash that can corrupt the internal memory of the phone. I think your friend's options are only two. Have it repaired or just buy a new one.
Yes it works but it's barely usable. It's blocking (getting stuck) and restarting all the time. Do you know maybe how to read those logs? I never used logs so I don't know. I was googling about it but I didn't understand it well. It seems that the phone has to be rooted.

Water Damaged Z2.. Trying to fix it!

Hello.
So to make a veeeery long story short, the phone leaked water in a lake at about 0.5 meters depth after a minute or two with flaps definitely closed (checked 5-10 times before submersion). The screen then flickered and died.
Phone gets sent away to a service center, tested and results unsurprisingly say its watertight so must be user fault. Sony and service provider refuse to help me in any way to fix the broken phone, so basically they say i have to pay it as normal (it was 4 weeks old at time of damage).
I received the phone back after countless phone calls to sony and service provider trying to get them to take responsibility, especially sony, but to no avail.
So now im trying to fix it myself. I took the phone apart, and the screen connector at the bottom was fried as expected. I bought a new screen and flex connector cable but still my screen wont show. The touchscreen works perfect, and so does the phone. When i connect it to my tv via MHL it works flawlessly. Every function including the new touchscreen works perfect, just that the screen is black on the device.
Am i missing something?? I really want to get this working so i can say IN YOUR FACE to this stupid company SONY. Im thinking the only thing it could be now is some faulty component on the mainboard regarding screen output, seems strange though that everything works perfect via MHL, especially the touchscreen.
Anybody have any ideas? Would be greatly appreciated if anyone can share similar experiences!
Cheers, Vincent from Sweden.

Hello.
The phone has booted ever since it got water damaged, even with the bad screen. Yes the touch panel works perfect but no display, and i can see and use everything on the phonebon my tv via mhl cable. I even updated firmware whilst using mhl to see if it would help but still no picture on the device.
I have replaced the touch screen and the flex ribbon cable that connects screen to mainboard. I have also removed mainboard and cleaned it with 95% alcohol incase some water or dirt causing a short circuit somewhere.
The mainboard looks fine, and everything works apart from the visual screen. Nothing is overheating. Im really baffled as to what could be wrong, but it surely must be something on the mainboard?

I got same issue on Galaxy S4 but that wasn't water proof so this type of damage was normal for it.
have u tried ur display on another board?
- as Sony said it was user fault... after phone get wet have u tried to dry it with heat?
+ as i read the warranty agreements when u open phone by urself or others (non official center) it will void the warranty.
anyway If ur display not working with another board so thr is problem in display panel and not anything on board.
Please Inform me if u got any info or result of this damage
Thanks

Yes the phone is thoroughly dried out. I only opened the phone after i had received it back from sony service. They said it wasnt covered by warranty because it was water damaged and was caused by the user (even though both water indicators behind the 2 flaps are still white and not been exposed to water), and they said that they never repair water damaged phones.
Thats why i decided to open it and try to fix it myself, i had nothing (more) to lose!
I havent tried the new display on another board, thats exactly what i want to do but cant get hold of a new board. I've even been taking apart previous smartphones to see if the display can be connected to it somehow just so i can confirm it works. But the probability is that it does work, as the first "broken" screen worked in the same way as this one, touchscreen fine but no display. Thats why i changed the flex cable also, i thought it must be that when the mainboard seems to be doing everything else perfectly.
Does the problem have to be in one of those 3 components? Screen, flex cable, mainboard, or have i missed something?
Thanks

Yes, it should be those factors. From what you have stated, its most probably the connector on the main board. Before you make more purchases, try to take it to a shop and ask them to test the screen on another phone, so you can see if its the screen or not. It MIGHT be a faulty flex cable that you just purchased, hopefully, since its the cheaper solution. I actually bought one in ebay that was water damaged, changed the screen, middle frame and flex cable, and have a brand new refurbished Z2, good for me the main board was intact. I would take the board out, wash it with 95% alcohol again with a soft toothbrush to brush impurities off the connector piece. Then spray it a little with electrical spray and leave it in rice to thoroughly dry out overnight and try all the connections again. Look through the main board with a magnifying glass and see if anything obvious burned out, the smallest connection can cause problems.
If all fails, then take it to a shop to test the screen or the main board, hopefully they are friendly enough to do it.
Good luck buddy. :good:

Sounds like good advice elbello
Good to know that you have managed to fix a water damaged Z2 using the same mainboard, hopefully i can have the same luck.
So you think it could be the flex cable? Are they known to break easily?
I have already cleaned the board twice with alcohol, maybe using electrical spray might help, and i will check it with a magnifying glass aswell.
Hopefully i can find a shop that will test the screen for me, but this is Sweden, the place where no favours are done, and where everything has to be sent away and fixed by professionals!
Thanks for the replys guys
I have just checked the whole mainboard with a magnifier, and found no oxidation anywhere. I found quite a bit of dirt in some places, and i have once again cleaned the screen connector with 95% alcohol and also the other side of the board behind the screen connector. I dont have any electrical spray at this time so cant test with that.
Another thing i have realised is that there is visual damage to two contact points that are located at the bottom of the phone, very close to where the flex cable connects to the lcd screen. What are these two contacts for, and could they be causing the problem? I will attach an image of them.
Thanks.

From that picture, I dont think that affects the screen at all. Bad thing is you cant try the two pieces you bought with another board so you can narrow the problem down.
I doubt the electrical spray will make wonders, it just good to clean dirt and make the contacts react better after oxidation, but if you state they are clean...
Think your only options is to consider it a loss, sell it in ebay for parts and stuff, or try getting a new flex and see if it was that, but if it wasnt, its like throwing money away. I would say the same for the screen, but those go for $100+ easily.

Yea i was thinking about selling it for parts, but its not really worth much without a working mainboard. I will probably just keep it and wait till i can get hold of a new board. How much do you think a new board would cost? I cant find one anywhere at the moment when searching on ebay/google.
Wish i had access to a working board for testing
Hello,
I have the same problem ... black screen on the tv works perfectly, xperia z2 also drowned after 10 seconds under water .... someone back to life solved the screen, that you have replaced?

Hello,
I'm now in the exact same position.
Water damaged, Touchscreen is still working I can enter recovery any press stuff but no display only shows black.
Had my screen replaced in a shop here but same problem prevails.
They told me to replace Mainboard 3500 THB.
But they didnt have one right then.
He could fix it?

Thinking of buying a used z2 with intermittent touchscreen issues. It works but seems to be intermittent it either takes multiple taps to work or it goes mad like your pressing the keys could this be down to water damage or possibly just a software issue and need re-flashing a ftf by clean install it's a totally stock z2 in mint condition for £50

It's probably hardware problem. Trust me, ghost touches make people go crazy,so don't buy it.

Ghost touches are a digitizer problem right?
You can buy a new one for about 30-50$

Xperia Z2 water damage? How can I fix it?

Yesterday afternoon about 4 o' clock I tried that my Z2 is really waterproof by putting it in the sink full of water. After that everything was working fine except the speakers and the microphones, but that's normal when they're wet and after they dried they was working fine. My girlfriend said that she called me about 5 o' clock and she said that my phone was off, but it was on, I'm sure. I read about this somewhere that after putting Z2/Z3 into water they can't receive calls. Except this everything was working good, but about 11 o' clock I realized that the touchscreen has a stripe that isn't working, but about 9 o' clock it was working. Now when I open the phone app I can't write 1, 2, 3 numbers. I opened the service test menu and chose touchscreen test and there was a stripe that wasn't working. I tried to reboot the phone and after that when I write in the service menu code nothing happened, it doesn't open the menu, but the touchscreen was still not working.
I tried to repair it via PC Companion but it became worse. Friday I will take it to the shop where I bought it. I have warranty so they should do it right? and with this problem they will replace it to a new one or repair the one I have?

Better late than never hehe... Also you could try a hairdryer with cool/warm air. I own a z1c and some water come into the phone 3 weeks ago (the back is loose in SIM card slot). The screen started to flick. So immediately I put it in rice and then used a hairdryer for 1 hour .And from this the phone is working fine.

on my hair dryer there is only warm function (what is really warm and I think that maybe it could melt the stickings) and it was 5 days before. I want my device replaced with warranty
how you opened the service menu if you cant press number 2 and 3 ?

Yes, it's very risky if you blow warm air into the phone. About warranty, go ahead, Just be sure that the indicators in every port are white, and take a close look to the back and front construction, maybe are loose or there are gaps (That's what happened to me)

Maybe . If those papers under every port/flap are still white, simply talk about the touchscreen trouble and gaps/loose on the back or front but don't tell them about water damage and request a refund or replacement. But if one of the papers is red tell them how the gap is related with the water damage and request the replacement. If they don't believe you ask for a waterproof/pressure test in the technical service. Anyway try to get a replacement. [emoji1]
now I'm waiting to that they'll replace it or fix it
I'm in the same boat (pool water though), still under warranty but I still fear they won't repair it.

for me they looked the phone and they said that this is a motherboard issue so they'll send it to a Sony Centre and there they'll decide that they'll replace it or repair it (I hope they'll replace it)
also check the water indicator if it's white or red (it's under the usb and sim card cover above the sim card slot). if it's white then they should replace or repair it, if it's red then they won't replace it

also check the water indicator if it's white or red (it's under the usb and sim card cover above the sim card slot). if it's white then they should replace or repair it, if it's red then they won't replace it

Before sending it, I checked it out and I think it's white so hopefully it's ok. I hope they replace the phone not fix it though, aren't these phones built for this type of stuff? it was just about 10 minutes (3 seconds interval) at the pool.

I used it in the pool for a short time, it was working fine right after until that day at night the touch screen started acting up, by midnight the touch screen was all but ruined (not responsive), I left it in some rice overnight, but in the morning it still wasn't working so I sent it for repairs (phone is only 2 month old under warranty).
The Xperia Z2 user guide states it can be used in chlorinated water and I made sure the flaps were closed so not sure I want the phone repaired seeing as it could be faulty, so can you keep me updated?

yeah of course. I called the shop and they said that they haven't got any news right now, no bad or good news. they said in the shop if it's water damage then sony centre will refuse warranty, even with the indicators are white. but if water damage is caused by build quality or something like this (not user fault) and the indicators are white then sony should repair it or replace it, I think. now I don't want replacement instead of repair, I don't care about they'll replace or repair, I just want a working Z2
Question: if the thing that is between the usb and the sim card slot is red, does it mean that there is no water inside the phone?
I'm asking out of curiosity, since i am not planning on dunking my phone into water

Is there any chance of a short circuit, loose screw or loose connection, any source electrical interference?

No loose connection there is one strap which is connect display to board it is perfect. If it is loose connection mean it should also not work at without sim but it works fine

Assuming, everything is ok with the screen, Sim card is still partially conductor. If something misplaced, it can interfere easily.

I checked a screen replacement guide, screen and touch digitizer plug and play, so they supposed to work when it's replaced properly.
Things you can do without opening the device that I found on internet,
- There is a suggestion to remove if case or a screen protector and I don't think it's relevant.
- Any other suggestion on the internet is knocking the corners of the screen.
- Getting kernel log and android log is another option. There might be something crashing.
- If you didn't reset the device already, you could try to reset it to see if it works.
Then there is no easy fix. You need to disassemble the device, check if there is wrong connection, dust, anything shouldn't be there. If you can find you can try spare screen. If there is no problem you should check components for faulty responses, voltage levels, etc.

Strange behavior after screen replacement

Hey Folks
So I replaced my screen in order to fix those ghost touches. I ordered a screen from aliexpress and its totally fine.
But since the replacement my cellular network connectiom goes crazy.
1. I wasnt able to register the phone in the providers network, so I double checked the antenna and now am able to connect. (antenna wasnt correctly in place)
2. I only get Internet Connection for some time, then I have to reboot the phone to get internet back. That sounds for me just like a Software Issue so I reflashed everything. But I still got that problem.
Has anyone got an Idea?
I now ordered an antenna Cable and a daugther Board, but Im not sure about that board. What about frequencies? Do I need to get an eu Board or smt for switzerland?
Greetings

I think that wifi sigaunal is joined to the daughter board. The cellular signal is handled by the plastic cover on top of camera lens. See if it is intact or have you played around or damaged it
i have almost the same problem.
Sim gets recognized but no network service.
Plastic cover looks undamaged...
