[Q] Digitizer remplacement problem - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

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

i will say this once, it is a general rule to keep in mind and everyone should follow it. If you dont 100% of what you are doing or how to undo what you want to do, you probably should not be doing it in the first place. SEARCH.

Google it. I don't think there's any soldering involved in replacing the screen. Ribbons should slide/clip in IIRC. There are plenty of videos out there. I followed a Youtube video to replace my Excalibur screen.

Lower part of digitizer not working

Hi,
My friend gave me his broken G1(digitizer+screen).
I've bought new ones and replaced them.
Now i have a weird problem that the lower part of the digitizer is not responding, i cannot open the menu button or touch anything there.
but if i hold my finger for few seconds and then let go then it will open a "quick search".. like it is responding.
is it possible that i've messed something along the way or that the digitizer was not working from the factory?
Also was wondering if there is some program to calibrate?
Thanks
Anyone?
can't help you actually, but i hope this hint helps you:
the g1 has a capacitive touchscreen, it doesnt require a digitizer / calibrating...
but as i don't know how capacitive touchscreens work in detail i can't help you...
I have the same problem :S
I have seen posts about the lower part of the digitizer not working. I think your digitizer is defective. Try wiping and installing your rom again or If you can, see if you can disconnect the ribbon connecting the digitizer to the LCD and then connect it back to the LCD, restart your phone and If it still does not work then your digitizer is probably defective. Contact the seller and ask for a refund or replacement would be the best choice.
Ye I managed to fix it.
I opened and reconnected my phone probably 100 times :S
Oh well, I hope its fixed permanently and Iwon't have to open it again incase it drops out again :S
If you just recently bought the digitizer, i would suggest you ask for a replacement so that problem would not occur again.

X1 touch screen issues and more

Hey guys, this is my first post, I'm glad to be a part of this community.
3 days ago, while surfing the web, my phone stopped responding. After restarting it, the touch screen stopped working with the phone flipped in landscape mode. In normal mode it was working fine. After one day the touch screen wasn't responding fine even in normal mode, I would have to perform screen alignment a few times a day for it to respond correctly. In addition to that, now the screen won't even change to landscape mode when I flip the phone, it just freezes. I don't have warranty, I have the latest software version from SE installed. Clear storage didn't help. Got any ideas? Do you think it might be a hardware problem or software?
Thank you for reading this!
PS: I've just reinstalled the latest software from SE and still the same
nat'
Welcome, bro, but sorry to hear about your problem.
Did you make any tweaks to the registry or anything? If not, I fear this is a hardware problem. You could try installing the X1 softtouch cab in my signature, because that maxes out the screen sensitivity, but I'm not optimistic.
Let us know.
This is definately a hardware problem, if your under warrenty send it in asap, other wise browse this forum 4 other cases
might be ribbon problem
anyway I would second it's hardware related
Thanks allot for the quick answers. After reinstalling the entire software again, I'm also pretty sure it a hardware issue. I'm gonna look into that ribbon thread. If I don't solve anything I guess I'll just have to take it to a service. :|
Hello, sad to hear about ur problem.
There has also occured a similar problem to me, but way more harder problem.
I read about the ribbon thing, and looked into it a bit more. How to open the whole phone and check the ribbon cable, also named flex cable if I am correct.
The cable were cut in half.. At the moment I am trying to find a store of where to buy one, I found a site from Sweden, cause that's where I am from but the price is not that cheap, around 600sek=85 dollars.
Does any1 know a site where I can find a cheaper one?
If not, I guess I have to buy this cable..
Edit:
I found another site, ebay. Way more cheaper than the previous site I gave.
http://cgi.ebay.co.uk/for-Sony-Eric...ries_MobilePhoneBatteries?hash=item563a472301
Sorry dont use the link above, out of sale..
Edit:
However, if the problem is the ribbon cable.. Go into ebay and search for Xperia ribbon cable.
You will find way more lower prices.

Usb charger port question!

Hi guys,
I hope this thread is in the right place but I have a question.
My usb charge port got bent a little bit and I had trouble charging my phone so I ordered from eBay the part I needed which is this thingy
http://i.ebayimg.com/t/New-USB-Charger-Port-Flex-Cable-Replacement-For-Samsung-Galaxy-Note-N7000-i9220-/00/s/NTAwWDUwMA==/z/4msAAOxyMxpRpE~d/$(KGrHqMOKpYFGWfj3M)VBRpE+d(Spw~~60_12.JPG
and then when I got it I installed it according to an excellent guide I found on youtube.
When I installed it,the USB charge port came back to life but the microphone (which I late found out was attached to the same flex part) was broken so I had to use my speaker for two weeks until the seller shipped the part again.
Today I installed the part again and now the USB charge port works fine,the microphone works fine,but to my supprise - the speaker doesn't!
My question is :
1.is the speaker also connected to this part and due to that I have this problem or is it possible that something else went wrong ?
Please only answer if you're sure of what you say.
2.Where can I get this part (OEM) from a place that will surely send a working part ? (if it's not possible to write it down here, please PM me)
Thank to all you helpers out there!!!

Open up the phone again. and check the screws that hold down the usb port
the speaker is attached to the plastic cover on top of the usb port. it is not making contact with the right points.
try it whilst the phone is on, play a audio or video file and hold down that part with your fingers. u will see that it will work.
meaning that the screws are either loose or too tight and not properly aligned.

No Audio after screen replacement

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

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
edi--
found the schematic here
https://data.dendik.id/Data/Schematic/Xiaomi/Mi5_SM.rar
now on the journey to repair this stupid mistake, lol
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
