Hello, I tried alot and hopefully someone can help me at my problem.
Mx Xperia Z had a water damage. At disassembling and cleaning the phone with isopropanol I scratched both data cables.
The phone is working again (everything) but now I have one problem. The screen is flickering at some colors at some spots as seen on the picture.
I think its because scrachting the data cables. Does someone knows for sure or with a high possibility what exactly could it be - Am I right with the data cable and what can I do?
I couldnt get the cable without display and just want my phone back 100% to work.
I would be really happy and thankful for some purposeful tips or especially for the final tip what can help me.
Best wishes

ps. As seen in the pictures. Its not in every color and not in every position of the screen. The flickering is a combination of color and location on the display.
pps. The flickering is sometimes getting stronger or lesser strong depends on the pressure on the phone / backplate. I´m nearly 100% percent sure it´s the data-cable. I added last picture after prssing backplate back on the phone. What can I do with the datacable? - Is it the datacable?
i do have same problem....no a single reply to this problem....did u got any solution for this problem plz reply

You damaged lcd flex cable (the black one on the right side) while removing your battery. I think that you don't have many options, you must change that cable (complete lcd). You can try with adding some thin tape on that scratch, and try with reconnecting that flex cable (see if the connectors on the mbo r damaged). Good luck bro.
the same problem with Z1
Hi,
i have the same problem but with Z1. I replaced display with touchscreen and i can see the same effect of flickering, stretching.
In my case, when phone is working longer I have more flickering, up to the moment when i can not see anything. The back side of phone is getting warm (around NFC logo). Also i got more flickering when on screen are pictures, icons with high resolution. Simple text are almost always clear.
Is it possible, that other thing than lcd cable is the problem?
My doubt is warming of the phone and that i got more flickering with time.
Also supplier wrote to me , that they check every single part before sending. I can not notice any visual signs of damage.

Hi there can anyone help me please on this matter.
My wife has a HTC One M7. last week the phone fell in to the bath. I managed to open the phone up and clean it.
The phone was taken apart and cleaned correctly using the correct circuit board cleaning solution (sorry cant remember the name).
I then ordered a new battery as the old one was not holding full charge. I also ordered a new screen + digitizer as the old one was cracked.
I have put everything together and charged the phone.
The phone charges correcrtly and has no problems at all.
When i switch on the phone it starts as normal and makes normal sounds etc BUT the screen is dead.
There is NO life in the screen at all even though its a new screen etc.
I know that the old screen is working and even using that i still get nothing.
Has anyone else come across this issue ?
Are there any guides to test the screen driver IC etc ....???
Thanks for your help in advance
It seems like that you have got a faulty screen.

MIght be a faulty screen as said above, maybe a broken or badly connected flex cable. And since the phone went into the bath, maybe a defective motherboard. Its very hard to tell.
as @alray said, it's hard to judge what's the cause of the dead screen, it may be one of the three causes.
so first, you can connect your old screen to the motherboard, if it can still work, to check whether the mother board was damaged or not
if the old screen can be lighten up, you can exclude the possibility of damaged motherboard.
second , you can connect your new screen to the motherboard again. Just be carefully and pay attention to the connector. Make sure it is connected correctly. If the screen can't be lighted up, you need try to use achohol or something else in a small brush to clean the connector. Handle gently to avoid damaging the IC. After that check whether the IC has lost some part or not. Then, if the flex cable or connector is fine, you can connect the new screen to the motherboard again.
finally, if the new screen still keep the same same situation. you can almost judge that you ordered a defective part.
May the steps above helps!
Hi there
the screen works fine as well as the connectors.
These have been tested on another htc one phone.
I have noticed that the motherboard connecter is damaged..... i will try to get some pics up later today.
Thanks
My nexus 6 falled from my hand to a small puddle of rainwater like for 15-25 seconds, i picked off it then i saw that all works normally i dried it with my shirt and, saved it in to my pocket after a few minutes i wanted to do a phone call but saw that the screen were all black and showing some lines i went to my house and tried some times to turn it on but anything worked, then i left it in a container with rice for 24 hours today i tried to turn it on but it is not working , when i push the On button it just show some lines with a very light green/yellow background and the green notification Led is turned on. What i can do? what is happening to my nexus?i need to buy a new screen? is there another way to save my phone?
Any suggestion?
Hope someone could help me
i had taken some photos but i can't post it due to the restrictions of a minimum of 10 post in the forum but there is an album with two photos of the nexus in my profile.
It could be the screen. Mainboard is also a possibility here. Someone is going to have to look at it and see what's wrong.

Thank you so much for answering, by the way i have posted some images of the phone in an album in my profile.
Rule of thumb with possible water damage is NOT to turn the phone on until it is dry. By turning on the Nexus, you guaranteed yourself a repair bill at best, or having to purchase a new phone at worst. Looking at the pics in your profile, your problem is on the motherboard. Someone will have to take the device apart and look at it to be sure, but you're likely looking at a motherboard replacement.
If you have a warranty, try using it.

[UPDATE] First i opened the nexus and disconected the battery from the phone dried competely with a towel then i left the phone for half an hour in a warm place then i dried it a little more with a heat gun , after that i left it in a bag of rice for two days and today i taked out the nexus, conected it to the charger then the green led started to turn on again, left it like for 4 minutes charging and then the nexus suddenly turned on! with all functioning correctly the screen the sim wifi all! , i was so happy and lifted up the smartphone to look at it but then the screen started to show some blurred lines and blue colors and a little bit distorsioned graphic interface in the screen but with all elements in screen.
Now i turned off the nexus
The problem could be the flexor of the screen?
because when i removed the back cover of the nexus with a guitar pick maybe i damaged the flexor or something like that
What i should do?

As I've said repeatedly, get someone to look at it. With the symptoms you describe, there could be multiple causes, and only a technician or repair center can determine the actual cause.

Thank you
Don't get angry
It was the flexor , All works nice but the flash does not work
I will try to repair it
I'm not angry, but I don't like having to repeat myself. Anyway, let us know if you get the flash fixed.
Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?
Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?
@fengels did You bought original lcd, where can I buy it in good price?
I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine
ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.

Well, will definitely try it then, but what alcohol? Does it need to be something specific?
