[Q] Xperia Z2 without image but turns on... HELP - Xperia Z2 Q&A, Help & Troubleshooting

Hi everyone,
I'm new posting here but i folow some tips and tricks from this forum along ago.
First sorry if my English is not always correct i now it... I am Portuguese.
I need some help with my xperia Z2, i wil describe step by step:
The touch of Z2 broken and after that booth LCD and Touch doesnt do anything, no image no light and no response from touch but the phone turns on and off, so I change booth lcd and touch from a official seller but it still almost the same no light and no image, it still turns on and now i ear the touch working but i do know what i am touching i can see nothing in the lcd... Then i replace the main flex thinking it could be a problem with the cable but it still the same... I tried to flash some roms and update with pc companion and all worked fine except the lcd stills the same... no image and no light... Someone can help me i dont know what to do now i about to selling it for pieces its all new in this phone except the mainboard... could be a problem in the board???
I almost forgot, it receives calls and sms but i dont see anything... i think all the function are ok just the image not.
I searched for hours in this forum something like this but i didnt found anything, i tried some tricks like the rubber and power + vol up but didnt worked. Help please before i sell it for peaces.
Greetings to all.

Sounds like the board to me, you've changed everything else so it doesn't leave anything else really

I think this can be closed if there is no more solutions... i tried everything... if anyone needs pieces for a xperia Z2 just tell me i have a new touch and lcd mounted on it i think someone could use the case of it... the board just for pieces its damaged.

Touchscreen broken ?

Hi,
i bought a used mda via ebay and got it yesterday.
First thing i noticed was that the touchscreen didnt work right... i somhow managed to get through the calibration tool that poops up if i turn the device on. After that the touchscreen worked really good for 1 day and then suddenly it stopped working completely...
Anyone had this problem before and can give me some advice ?? I already got a 20e refund but i want to try to repair the device instead of selling it as broken.
And another question i have: Can i use the wm 2003se on a german device ??
Thank you
Seraptin
Edit: got it repaired myself... I opened the device and cleaned everything... there is still some dirt between the glass and the screen.. if anyone knows how to remove the glass to clean that, im listening But i dont think thats possible anyway.
my screen is broken
Hi,
Glad to read that you have repaired it yourself. I just dropped mine on the floor yesterday and the screen is broken. Touch screen still works but the screen is cracked and I can see a black spot. I wish someone can help me purchase a new screen. I would try to install it myself.

[Q] Xperia MINI PRO sk17 , screen remains black, although working

HI everyone My Xperia Mini Pro worked just fine, then one day the screen remained black after unlocking it... it still worked, i could feel the touch and vibrations, i could basicly do everything just that i wasn't able to see it. After some shaking, pressing, sliding the keyboard out, it came back to its normal state, but would go black again if i pressed it hard and hold...Now the screen is always black. I hadn't really dropped it, it wasn't exposed to high temperatures, it just happened......i took it to some service centers and they have changed the flex cable a few times but didn't work..they assumed it was a hardware issue.....My warranty's long out.....WHAT SHOULD I DO???...Is there a chance that a screen change might help it and what would it cost me? please help

You have to replace the screen of course . Not very expensive i think .

My friend broke his XMP screen bro, and in the service center they charged it too heavy such that he can buy an another device
try flashing stock ics just to check if it is software problem else you have to bear expenses if you cant miss such a good device

[Q] Xperia PRO - touch digitizer recalibration?

Hi boys,
yeasterday I changed digitizer on my Xperia PRO mk16i, which was broken, but still fully functional.
Now I have problem with this new - in the middle of LCD it´s don´t read my touchs. In the top and bottom of LCD is situation better - it is almost functional.
I found some recalibration functions, but it´s no possible via standard phone menu. So I tested change firmware with Flash tool. I tested A 2.3.4 and 4.0, but everything is bad - I cannot found any calibration function. (When I bought my phone, first thing which I must do was calibration).
Please, can you help me? What I must need for run calibration process?
Many thanks,
Petr
Wow, I've never heard about touch calibration on capacitive devices. I'm pretty sure your new digitizer is defective. Happens to the best of us hehe.
I have similar problem with this guy. Middle of the screen doesn't read my touch, I'm using mini pro. My case I hold my phone with wet hands, then the day after, it happens. Flashed to stock didn't help. It seems your digitizer is defective as said. Take the phone to where you changed the digitizer and ask for warranty.

[Q] [HELP] Xperia Mini Pro Broken Screen

Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!

[Q] SOS: Elephone P8 touching itself??

Why, hello there!
First of all i would like to apologize for two things:
(1) My English is awful so bear with me please!
(2) I couldn't find an answer for this question and i tried really hard. So if there does exist an answer please point me to it nicely
Now, concerning my problem.
I have bought Elephone P8 from Banggood . com
(link could not be uploaded cause i am a new user)
(if you want to view the phone go to Banggood and searh for Elephone P8 :angel: )
From Day 1 I have had a problem with my screen. It touches itself!!
I didn't do anything for that problem as i didn't believe it could be possible for a phone to touch the screen itself.
Now into details:
When i unlock my phone and use it after a couple of minutes (i have enabled the option to view the clicks on the screen) i see thousand clicks on my touchscreen in a vertical line. From the speaker (where you talk) to the home button. It is always in the same line!!
And when i close the display of my phone and unlock it again, the thousand clicks stop and the phone works normally again.. :/
I know that it is hardware problem because i have changed roms, i have rooted and i did all i could to fix it softwarely! :fingers-crossed: SO i am convinsed it is Hardwared reallated issue! :victory:
MY QUESTION IS:
How can i fix this problem if i want to open my phone?? If i change the glue between the glass and the LCD will it fix it??
Please , please , please! Don't tell me to send it back and ask for a new one OR take it to an expert to fix it!
THANKS A BUNCH GUYS!!!
It could (!) be just some stress on the Screen. Maybe you could do something if you just disassemble it, look where the stress could come from, and put it together again after that.
I had that a few years before, and for me was the Solution to bend the Case a bit, in which the Screen was pressed.
Hopefully that works for you
Thanks for your reply man! I really appreciate it!
Now that you mention it, when i dissasembled my phone i couldnt unscrew the last screw that is attaching the motherboard to the screen. It was so hardly screwed!
Maybe that little screw does the job, so i will try and unscrew it!
ONE MORE THING
If for some reason i can't find the pressure point from inside the phone, what other options do i have?? Since i have scratched the front glass a bit, i am in the temptation to change the front glass and clean the Screen a bit.
What do you think?
P.S.: Further advice is very much appreciated!
