So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Hi, I've still got a SPV 500 and a MDA Compact, need to find it if you want you can have my MDA Compact screen.
Just PM if you are interested.
Hey guys!
I've a really big problem:
I tried to fix the "white screen of death" syndrom of my SPV M3100. But when I put together the phone again (the LCD-part) I didn't push in the flex cable of the LCD hard enough into its connector, so when I closed back the LCD part, I might have damaged the flex cable. What I know for sure is that I broke the 2 white small crooks of the connector (by accident of course). Now when I turn on the phone, the screen stays off (but the upper LED for GSM/UMTS connectivity glows for a few seconed, also the LEDs from the small keypad), only when I push hard enough on the LCD-flexcable-connector, I see a white screen, sometimes some lines, but I never saw a "good screen" again. Now my fear is, that I screwed up the LCD flex cable, what can I do in that case? buy a whole new LCD only cuz the ribbon is broken? Do I have to replace the flex cable of the phone itself too, (cuz the crooks of the connector ar broken) or can I glue the connector somehow?
I hope you know what I mean. If you need any more info plz ask me.
Plz help me in this issue, this phone is the best I've ever ever had, I don't want to lose it! Thanks in advance!
greetz from Vienna, sebid.
PS: took you a pic, so you know about what connector I'm talking about.
You will need Both.
Go on ebay and try to see if someone is selling the same Cell for Parts that might help you in getting your parts cheat.White Screen is indication of a bad LCD and you said you damage your flex cable too so should try ebay for a Parts Phone.Good Luck. D
I now have to fiddle with the connector to charge and/or sync when plugged in
I suppose after nearly 18 mths of using in car at home on the move and jabbing in various Micro USB connectors it was inevitable that there would be issues
Can anyone advise if repair is a viable option & if so where .......... UK Midlands based
Many Thanks
Via the HTC site or look in the Sunday papers, its a new motherboard, so its about £200 via HTC
Or.....................do it your self instructions are on this forum somewhere and the spares on ebay
Sorry, after looking there is no motherbaord currently on ebay
a bit of switch cleaner, maybe a (very)dry soft toothbrush, give the port a spring clean. Grime can build up in the bottom, stopping it pushing as far in. even a 1/2mm in a corner can be enough to stop the connector being snug.
New motherboard is the easy way yes.
Just buy a broken HD2 and swap the motherboards.
Resoldering is almost impossible, so tiny,
Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!
I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm
Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!
From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered
Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

Hi guys,
Here is my contribution to da community, hope so it helps.
h t t p s : / / docs . google . com/open?id=0B9lrf7AWQW7ETjRZTkFXb1luN0E
On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.
^^ Here is the link for above! (Thanks!)
Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.
^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.
Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone
No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

I don't have he white antenna coaxial cable neigh the PCB antenna board that this cable is connected to but I have WiFi.
Could it be for WiFi N(150Mbps)?
Watter damage, LCD working/not working?

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.
