[HELP]Replacement Microphone - Verizon Samsung Galaxy S III

So my phone went for a quick swim a few days ago and the microphone seems to be the only thing that suffered any damage. From what I understand, it's a module that's soldered directly to the motherboard. I've seen modules that claim to be for the SIII online going for under a dollar.
Has anyone had any success in replacing their microphone module on these phones? I've been told that the module is "heat sensitive," making soldering impossible, but that seems counter intuitive to me, since to the best of my knowledge, the module is soldered to the board in the first place. If anyone could point me in the right direction, that would be splendid! Where to purchase parts, how to fix, where can I send it, etc.
Thanks.

NVM fixed. Bought a new board and replaced

[Q] Nexus One main microphone repair/replacement?

Hi all,
I've recently had a crash - my N1 fell out from my pocket while climbing (stupid, I know..) - cracked screen, all that.. I've managed to replace the digitizer without big problems, but I have a more serious issue: the main (built-in) microphone stopped working and now I have to use the headset for every call
I've sent it to HTC service and they said the motherboard needs replacing and wanted me to pay 300$ for it..
Since it's quite a lot for a microphone, before buying the new one (at least 200$ for tho mobo alone) or sending it again to the HTC guys for repair, I'd like to ask you if there is anybody who had anything to do with those microphones or issues similar to mine.
The microphone itself is a small gold rectangle-shaped thing glued to the motherboard, but I cannot make out any markings on it (there seems to be something written on it, it's just not readable any more). It seems to be exactly the same as the noise-cancelling one near in the upper part of the phone. Of course, before cutting or soldering anything I'd like to know as much as I can..
So.. the questions are:
Has anyone repaired a thing like that or managed to replace a microphone on Nexus One motherboard? How could this be done?
Does anybody know where I could buy a microphone that would match?
I know it's a long shot (and a long post ), but I figured it's worth a try to look for somebody who might have some insight.
Thanks in advance,
Kuba
P.S. Could anyone move this question to Q&A, please?..first post gone wrong..
you could just buy a new one for under 300$ on ebay or a used one for less than 220 for everything new If something like that is messed up its not worth fixing, too much work
hitmanre,
thanks for the reply, but...
As I said, I figured the part on buying another mobo (or a broken N1 for parts) on my own.
I was just curious - from a DYI perspective - what's going on on the board and what's actually broken around the microphone.. If it was only the microphone then it should be easy enough to replace - but if it's a crack somewhere in the inner layers of the board, then bummer..
In fact, I opened my N1 again yesterday and cut the mic out...curious thing is that there seem to be only one connected soldered part between mobo ant the mic.. Could anyone explain how a microphone could work with a single connector? there doesn't seem to be any ground connection anywhere..
If I have some time, I'll post photos - but no sooner than in a week - going on vacation
See you,
Kuba
I have the same problem, and I live outside the service coverage area. I've had my Nexus One since May 2010, so it was more than one year old. It's really sad to quit such a really nice phone just because it can't make phone calls. It seems that nobody here in Lima know how to repair a N1. And I'm so afraid to open it...
I have seen 2 of these phones with the same issue. one mine and second a customers. and I have tried replacing the mic headset jack (headset jack can short out audio) and still nothing. mic works with loudspeaker but not in normal mode with earspeaker.
ok today I was able to get my hands on a working nexus. and swapped the upper flex and that fixed it.
the only thing is that we ordered this part from one of our sources to fix a power button (which is on the same part) and it had this issue. so I had to replace it again

I also have a problem with the mic suddenly not working and working again suddenly. So it must be a damaged flex since the phone has a dent on the upper left part of it.

Chances that an LCD + digitizer will fix this?

A coworker I started working with a few months ago told me about the much-better Sensation he had before his MyTouch 3G. It seems that he still had it, but stopped using it "because the screen cracked." I correctly surmised that it was a simple and cheap to replace touch screen digitizer and described to him that it was "just the glass cover" and that it was "cheap to replace." I have done many such repairs on other phones and gadgets.
He then told me that he had continued to use it until the LCD went blank. There is no reason to think that the LCD inside suddenly cracked, but I can only assume that it also sustained some kind of damage and now also requires replacement. Knowing that the LCD isn't cracked, what are the chances that a replacement LCD + digitizer will restore the phone? I'm concerned because we've already purchased a kit for $65.
Nobody can tell you that off the internet. If we do, that would be pure guess, just as accurate as you would have guessed.

Well, someone could have had the exact same problem and already tried it. I ran into people with the same problem already. I'm just looking for more because some, no doubt, have tried it and others may have an alternate explanation. Reasonable.
there is a good chance that will fix the problem. but since the LCD was working for a while until it blank out, it is possible the problem might be with the circuit board. only way to know is to try it out.

The LCD could go blank for several reasons. Faulty LCD, loose cable, faulty board etc. etc. Even if someone had the same problem, the reason for it could be completely different, thefore this wont help you at all except for giving you hope. If this is what you need, then i would say "yes, the change of lcd & digitizer should fix the problem" but you never can be sure unless you try When you start the phone, do you hear the startup sound? This could at least indicate that the phone isnt completely faulty.

The plus side is that you can't make it worse. So you've got nothing to lose by trying to repair it, other than the few bucks for the parts.
Well, I took it apart to re-seat all the cables and it's still blank. Reading online, I see that a lot of dropped Sensations/Pyramids develop a loose/broken SMT capacitor component near the headphone jack, but I'm not registered on any of the forums I see it discussed on and I can't see the pics. They describe a slightly different problem anyway (screen goes blank after standby). I needed sleep, so I put it all back together and I'll check that out when the parts get here. My hunch is that the LCD panel is fine and that I'll have an extra, assuming the capacitor problem is fixable. I've done some delicate soldering work before but I can't really say that I'm good at it! I didn't see any loose SMT components rattling around so I hope it didn't fall completely out somewhere.

Thanks but it's almost $70 for the parts.
Works great! Well, it had the touchscreen sensitivity issue pretty badly but the T-Mobile OTA update fixed that. Transferring all the adhesive bits from one screen to another was down-right frustrating, but I pulled it off and I only see a single spec of dust inside. The dude will be thrilled. I broke the earhook on my Looxcie so I did not make a video but it was full of me tearing and ripping the things anyway and not a good example of how it should be done!
FWIW, there was no way to remove the old screen without denting up the backing plate and prying the heck out of it to free it from multiple adhesives and glues, so I would not have had two good LCDs after testing the replacement even if there was nothing wrong with the original. Good thing it was the LCD at fault! I didn't have to drill anything like the glass replacement video I watched instructed me to do. They didn't realize that the LCD removal allows the flex PCB through just fine. I forgot to thread it back through before seating the replacement LCD in the adhesives and tape left-overs but it flexed enough to allow it through without removing, which was quite a relief after seeing how the original fared after being removed.

Look above pictures please.
I sold a phone on ebay ( phone was about new) and buyer said phone isn't working so ebay told me to do a refund and get the phone back. Phone came back like seen in the picture.
Any ideas on how to fix this? Can it be that somethink got out of place during shipping?
EDIT:
Update info:
I removed battery cover and battery, squeezed gently all over the phone, put it back and phone started normally, after first reboot it became grainy again.
Can it be that something got unplugged?
I have no warranty on this phone, so to open it further will not void any warranty, can anyone point me what should I look for?
Awaiting any comments,
Thanks
help
Any one to pass an idea here?
Solution
Well, I managed to fix this phone and thought to come and share what I did.
First I kinda narrowed down the problem to lcd or main pcb board.
As I have two htc sensations 4g (t-mobile usa) Ithought I will open both and try main pcb board from bad phone on good one.
Problem was on main pcb board as it did the same grain display with it on good phone.
After I put together phone which originaly worked fine I examined this bad pcb board and everything seemed fine to naked eye.
I connected all cables and flex cables and before putting back cover with 6 screws I tried it once more and its was same grain picture.
Then I gently pushed over video flex cable connector and phone was all fine. I removed the battery (which at this point I was holding in place with my hand) and used a piece of wood to push that flex cable connector some more as it seems that was one part which was doing all this.
Seems that from fall this socket (connector) moved out of its place.
In case you need to do this or anything inside your phone I sugest you watch this youtube video:
Code:
http://youtu.be/go8l4XeiGM0
I didnt understand much of what the guy was talking but video quality explained it all.
I hope no one need to go through this, but if you do then my experience with it might help you.
Check picture of connector in question:
Bake it
I had the exact issue and after I tried everything and was ready to order one from ebay I put it in the oven for 6-7minutes at 360 degree.
Its working perfectly for last 2 months now with no issue.
NOTE:
Please do this as last option as I did.

any one have the schematic?

so i recently purchased a used doubleshot to give to my fiance, her biggest deal about a phone seems to be the camera and her g2 just isnt cutting it. well im cheap and handy so i buy all my phones broken and just fix them.
i found this almost mint doubleshot for about $50 with the only problem being the internal speaker is shot. so this is should be a hardware fault most likely but to be safe i rooted it and gained radio s-off and flashed a few roms. definitely hardware. so i bought a speaker for $7 (should be here by weeks end) and looking around i see the main flex being sold with the internal speaker attached. this got me wondering if the speaker simply sits against the contact points (my experience on well every phone ive disassembled) or is it soldered or what?
i dont mind doing the extra effort but google has not explained to me what i should expect. i even called htc and of course got the id love to help but i just cant response. so if anyone has experience with this or can point me to a full breakdown (not just digitizer replacement as it skips this) i would be forever grateful. thanks!
Here is a guide to help aid you in the taking apart of a doubleshot.. I'm not sure what help it is, but this is all I can personally help you with as I haven't any experience with this. http://forum.xda-developers.com/showthread.php?t=1586028

Send a message to jjbz. I traded my bricked DS for a working one with him and he said he's going to use my old one for parts.
Sent from Spaceball One.
The internal speaker is soldered down to the ribbon cable. If you are going to attempt to replace it yourself be vary careful of the light and proximity sensors. I fried the proximity sensor when I attempted to solder in a new speaker. After a month of dealing with the missing proximity sensor, I went with a new ribbon cable.

[Q] Question about One pus One logic board

Ok well here is my issue. While replacing the LCD assembly on my one plus one I managed to rip off the metal connectors(I believe they are called pogo sticks) on the logic board that make contact with the antenna's on the back cover. I ripped the ones that control the WiFi/Bluetooth and also the GPS one. I was trying to figure out how to fix this since when trying to soder them back on there was nothing they could be soldered to. I'm basically left with the empty spots on the PCB board where they are supposed to go. While looking at the logic board I saw that there are a couple of pigtail looking connectors on it that don't have anything particularly connected to them. I was wondering if I could use those to repair my connection issues. Or of any of you have any advice to give thank you for all your help ^_^
