Hi
I bought that ; http://www.ebay.com/itm/LCD-Touch-D...102?pt=LH_DefaultDomain_0&hash=item4602f56036
once I installed all the pieces, I restart the cell. It starts, I can hear sound, but no image on the actual screen. What could I do wrong? Does anyone has a video? All I can find on youtube is a video of how to disassembled it but never how to change the digitizer.
Thx for ur help!

just make sure the flex cables are plugged all the way in.... if the lcd plug is just barely off it will not work...if all are plugged in it should work... there is a chance the part could be bad..(it does happen) if so just return it for another.... but the best advice is check the connections... dont force them... but unplug and replug them... anything that has to be forced is wrong and will cause damage if you force it...
no real need for a video as with the part you have shown is a pretty simple remove a few screws and unplug connections... also inspect the flex cables on the new unit... one small nick in the lcd one and it also could cause this...
hope this helps...

I tought that maybe it had something else to swap or something.
I already sent back one digitizer to the sender cauz the other one wasn't working... So my guest was that if a second one didn't work I was probably the problem but seem not...
When I reinstalled my old (and broken) screen its work like a charm.
Anyway thx for ur help I'll try to reinstall it
Moved To Q&A
Please post questions in the Q&A section
Thought I'd share what I've just done! I (rather stupidly) was listening to music while working on my car - the only headphones I had to hand had a big size (6.35mm) headphone jack, so I had an adapter in there too. Al this meant a rather large lever poking out the side of the phone. I'd obviously bent down to do something and wrenched the socket to one side. The 6.35mm adapter had been bent over and broken... and when I tested the phone I found the socket was broken to - only working in one ear
I went on line and found this guide to dismantle the phone! http://www.youtube.com/watch?v=kGD64_g-ssE
Actually nothing to it! Except Even though I do have a very small set of screwdrivers the screws used on the phone are really small!
I bought a new headphone jack from here for £20.08 delivered : http://www.etradesupply.com/catalogsearch/result/?q=lg+p880
And it arrived in the UK in less than a week from the US!
Out of interest the headphone jack can be removed without any of the other circuit board connectors, or the board itself being loosened.
It also houses the proximity and light sensor, I did put it back together and find the proximity sensor was constantly reading 'near' (using the hidden menu 3845#*880# )So I quickly opened it back up again, removed and replaced it one more time. Now it works great, I must have had it badly placed
Well, at least the video was not published in vain
Nice work!
Sent from my LG-P880 using xda app-developers app
Thanks for decribing this.
I guess I have to replace my jack, too, since it doesnt hold my headphone strong anymore and sometimes the electric connection of the headset mic gets lost.
I have found the jack for about 5$ incl. shipment at DX:

I got the ETrade one. Also I think parts4repair.com sell parts for the p880.
The little arm you can see poking out actually bends and doubles back under the socket part. I found my screen wasn't waking up when I moved the phone away from my face, I just opened my phone back up and padded it out (between the socket and the sensor part) with a little shim (card etc, I actually cut off and used a little piece of a lens cleaning fine cloth) and now the screen wakes perfectly for me! That was my biggest gripe (apart from huuuuge lag when the browser opens!) and i no longer feel I need to ditch the phone!
Don't lose the little square rubber part that the sensor part sits in! And I recommend using a tiny flat-head screwdriver for the phone's screws, the posi-head screws are so tiny I couldn't get a good fit, and it's all too easy to ruin the tiny screw heads.
on/off button doesn't work.
Anybody know how to fix the on/off button. ?
I'm really pissed, I've had the 4x only 6 weeks and don't think I overused it.
button placement and size isn't that great to start with.
I flashed Arararagi vanir 4.3 and it was running great too.
I've never had any problems with the headphone jack, have my phone for about 4 months now

The on/off button? buy a broken 4x?
I took mine apart a few months back to clean the inside of the screen.
Had to send it back to LG as had a few issues regarding call quality and the screen not coming back on when you take it away from your face - Just got it back and they replaced a case and a lense? Not sure what lense though.
It also said Software update - They sent it back with ICS

they probably even permanently locked your bootloader, if it was unlocked your "phone not turning on when moving away from ear" problem was sensor miscalibration that you could've fixed easily.

No. it was new when I bought it.
Had it for 6 weeks before the power button stoped working.
just used it everyday, rooted it, a few roms, then daily use.
i expect something like this from a cheap chinese knockoff, not an LG 4x. i had a star b92m where the screen became unresponsive.
next time I'll get a SONY XPERIA Z.
The 4x has been in the shop for two weeks already. .
OverVoltage on the headphone jack =(
I believe is overvoltage, I connected a plug from my radio for louder music(as I usually do) but wasn't working, and tried moving the connector on the radio and instead of plug in input from radio, I plugged in the output from the radio, a sound came from the radio and that was it, no more sound signal from my P880, I love this phone, I'm so angry about this.
So I checked with earphones and nothing, just noise, no volume up or down, and the headphone mode is turned on all the time, do you now a site where the earphone jack flex can be delivered to South America, Bolivia? and if you have some other suggestions or solutions specially for taking out of headphone mode, I even can't make calls! thank you in advance
The two parts places I have used are I have used are etradesupply and parts4repair. There's probably lots of others out there. Not sure where they ship to though

Hi,
Sorry but I don't understanting ... in the video the motherboard is removed. You replace the headphone jack without removing it?
Thanks
Help me please ....My galaxy note n7000 showing charging message after removing charger pin.............:crying:
Try rebooting the phone... It should solve the problem
Hit the thanks button if I helped you
clean the charger port with a needle with power off. if it is clean there is this thing in the middle of the port that you have to push it higher very gently. don't blow in the port .

most probably the port.. clean and test it
got around to cleaning the USB port, now it's fine. It was also affecting transferring of files larger than 400mb from PC to phone too. the phone would freeze and I'd have to reset it.
Thanks for this video. I faced the same issue which is now sorted out after cleaning the charging port.
Thanks to the OP who floated this thread.. I had similar problem yesterday. special thanks to @andreasarxon. and nokiamodeln91. Thank you guys at xda. Probably due to rough handling of usb cable this happened. All is well now.
Clean It With A Little Whisky :]
cotton, dip it in a little whisky and then clean the usb port with a help of a needle/pin... worked for me :]
*make sure your phone is turned off and the battery is out while you do this application*
try and clean your charger as well.. Cheers!
you would have to change the usb port inside the phone. small cleaning here and there is just a temp fix. fortunately the part is easy to install. Takes 10 minutes total. You must take out the original part and take a look at the revision of the part. comes in rev. .8 rev 1.0 etc. Mine is rev. 1.0. now the bad news: most parts you will get from ebay will be defective. I have had 4 usb ports and only one worked. Most have microphone problem. No mic and the other party can't hear you. one had problems with mic and also with charging. The last one had problem with mic which produced loud distortion and no sound can be recorded apart from distortion. In order for you to get the right part, take a look at your defective usb port inside the phone and write down the revision number. must have the same rev number. Then make sure you buy the part with the antenna amplification tape in the back to amplify the cell signal. the parts without this tape will give you a weaker cell signal (40% less). this makes a huge difference where signal is already weak. so take a look at your original usb port first and then get an exact one with reflective tape on the back covering the antenna.
good luck

Hi guys. I recently broke my screen on my one and i order a replacement for it. I decided to do the repair myself and everything went well but when I powered on the phone after i had replaced the screen i noticed that the camera, the upper speaker and the headphone jack weren't working. They are all related to the sister board but i can't find what i have done wrong. I have already checked the connections and i flashed a new rom just in case it was a software problem. Can anyone help me with this? Is there a connector that connects all these things to the mother board?

before you do everything/anything see these videos first, or you can follow how to reassembly it, maybe you forget to connect cable/s

I have already watched these and everything seems to be in place. What is weird is that the vibrator which is a component of the sister board is working fine. I' m trying to figure out which cable connects the parts that are not working to the motherboard.

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

found the schematic here

any help from someone who are an expert in this thing will be really appreaciated

Yeah, tried it before, and the audio chip is gone
Perhaps something wrong with the audio chip, will try to replace the IC tomorrow
