[Q] Nexus One main microphone repair/replacement? - Nexus One Accessories

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.

Polaris Scroll Wheel \ D-PAD Broken :( Need Advice

If anyone knowledable on anything that pertains to my problem could help me out I would be very grateful..here's the scoop..
I have had my polaris for over a year now (out of warranty) and for the longest time I've had issues with the touch screen not responding correctly and having to re-calibrate it all the time. I finally figured out what the issue was yesterday after I hard reset the device and the screen was still messed up...I had been using a dock for this device that isn't manufactured very well -- using the dock day in day out for a few months at work actually bent the pins on the USB connector on the cruise to the point where some of them were touching each other (yikes!)
So, I gave the phone to my dad who's an engineer, he took it to work and used a microscope or whatever and some tools and got the pins back straight again..now the screen works fine! Needless to say that dock is in the garbage now. The brand was "BoxWave" -- stay away from their products, they are JUNK!
Anyways -- I still have a problem with the scroll wheel.
Spinning the wheel does not work at all -- the Up, Down, and Left buttons work when pressed, and the wheel does light up, but spinning it doesn't do anything. Also the Right button doesn't work either. The button in the middle works okay. All of the working buttons cause the light to go on.
The logical conclusion here to me anyways seems to be that the bent pins caused permanent damage to the scroll wheel...I'm very glad it didn't cause perm. damage to the screen (or anything else, so I hope!!)..but anyways -- what would be the best option for me at this point?
Call HTC and have them fix it and pay out of pocket?
About how much would they charge for something like this (ballpark)?
My dad is a very skilled electrical engineer -- he would be willing to take it apart and fix it for me at work..he's got all the tools and stuff for it and doesn't mind at all...what parts should I look into ordering?
Thanks for any help anyone can provide here.
Hi,
I have a similar problem the up, left, right and turning the wheel does not work on my polaris either and I have not damaged it whatsoever. So, i do not think your button problem is because of a possible short circuit. But, sorry to tell you but I do not have a solution to the problem.
I thought I was certain, but occaisonally my screen still dies.
Perhaps it was permanently damaged? It is much better than before though -- but no matter what I do -- the wheel spinning does nothing, and the Right key does nothing at all.
Do you have any clue what part we would need to get replaced?
I am looking to replace the screen as well due to scratches.
I believe it's called a "digitizer" (the screen part not the wheel)
No, sorry. But if you do find out let me know as well.
Thank you.
found this on ebay
Hi,
Guys I found this on eBay. It says it can repair this kind of issue. Although I do not have the time to test.
So, here it is
http://cgi.ebay.com/HTC-Touch-Cruis...ries?hash=item19b5e3f64f&_trksid=p3286.c0.m14
P.S. if anyone does test this please give us your feedback. Thank you
What?
Did you post the wrong link or something?
That is a SIM card.
This thread is about the scroll wheel \ DPad.
EDIT:
Nvm, I see in the auction it says its a ribbon or something.
I dunno about this one...but it's cheap.
I still have not even gotten around to repairing my screen \ usb port though...god damn money.
If i order this ill let u know.
OK so I just purchased a new charge port and digitizer, but I have yet to see ANYONE selling a replacement scroll wheel.
Alot of people are selling the "housing" but it's missing the wheel!
Anyone know where to get a replacement metal panel and wheel only, not the entire housing?
I found a jog wheel for the shadow -- wonder if it would fit?
I have the same issue, the jog wheel doesn't work and neither the right button, but everything else works & lights up the keypad part....strange that this is 3 of us with the EXACT problem, maybe there's something we need to figure out? btw, i used to hardly use the buttons, but i used the jogwheel a lot to scroll.
I also have the BoxWave dock, however, i've found mine to be of great quality & use...reading your post made me paranoid so I checked my usb connecter over & over but thankfully everything looks very normal.
I came across this post, because I was actually looking for some user advice on replacing your own housing & wheel. I already found the entire housing & keypad on ebay that comes with the screwdriver set, and i have the manual to assemble & dissassemble.
I would rather do it myself so i wouldn't have to do without my phone while waiting for this to get repaired, but i also don't want to do it if it's very tricky with a big chance of busting phone, so i'm looking for a feel of easy-medium-hard. I've already done something similar 3 years ago to my I-Mate Jamin as well as replacing the speaker, so my technical skills are probably around mid-level.
Anyways best of luck, i'll update this post later to tell you how it went (this could be in 2 weeks time from now).

Housing including the jog wheel and electronics?
I also ordered a usb connector and apparently they sent me one that isn't compatible with the cruise...I think I am just gonna buy a broken one and get the parts from it..they seem to be rare compared to other HTC models!

I had the same problem but on a 2 year warranty Touch Cruise. Phone was fixed and re-installed with WM 6.1
Know I face Bluetooth connection problems again and the BT hotfix is not accepted anymore.
I do have to say that the upgrade after re-installing should have been left behind.
I have the same problem... Scrol wheel not working en button to the right
anyone ever fixed this?
Hey Guys!
I've got the same problem with the wheel and the right button. So I was wondering if anyone fixed the problem?
I have no warranty anymore
I think I know what's your problem, mates.. It seems that it is essential for almost any P3650 - the cable, which is going from the jog wheel to the keyboard control unit tears apart just before (or exactly at) the copper pads on the molex thingie, that plugs into K/B unit (damage is so slight, that it barely can be seen).
I had no luck looking for the jog wheel sold seperately from housing, or at least with that plastic-chromed buttons cover. If anyone finds out that it is possible to obtain it seperately - I would greatly appreciate
Btw, same problem goes for sim holder's cable - I have replaced mine 2 times already (you can get 'em for around 15$ from ebay).
Sorry for my english - it's a bit rusty atm
Same problem here..wheel doesn't function can't find the part by itself ..
Touch Cruise jog wheel & keyboard
Exact same here - jog wheel scrolling broken & right selection does not work. Besides, my "call" key stucks time to time.
So for now I've just got both of them - jog wheel and keyboard (not the entire housing) from ebay, 15 & 7 $ respective
wheel ordered from the following ebay location :
cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rt=nc&nma=true&item=260656153778&si=1E2jM09T8qOM9DzM6uzrXo5Qiqg%253D&viewitem=&sspagename=STRK%3AMEWNX%3AIT
same provider has keyboard also, for some reason it is not on eBay active items. But you can contact the seller and ask for it.
I gonna replace both in a near future, and will update about the result.

[Q] htc pure

I am trying to take apart my htc pure. I cannot get the part down by the stylis to release. there is a small body part still in place after removing the battery cover and the torx screws. has anyone taken one of these apart willing to give me a hint?
thanks in advance for any clues
got it apart. turns out there is a little plate just under the front nav buttons (will post pics later if possible) that needed pried off to reveal 2 other screws. I got the speaker to work, kind of. it has a lot of crackle to it. now I have a few questions I am not sure on.
how can I tell if the unit has previously been modded, should I search the rom revision on the forum?
if it has been modded, possibly just a bad radio file has been loaded, I kinda doubt that but could that be possible?
lastly, does anyone have any idea where to purchase a replacement ear speaker? I have searched high and low. only found one new they wanted $85.00 for just the speaker. Gee, little high.
I have seen dead units on ebay for $40.00, thinking that may be my only option now.

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.

Microphone not working after repair

I've had my Nexus 5 for over 3 years now and it has seen countless ROMs, Kernels, rooting, all that kind of stuff. I also bought it in white and decided after some time that I want a black one so I bought a frame and a back panel and moved everything over to the new assembly. Shortly, it has seen a lot of mods.
My father used it for some time and one day he droped it and the microphone didn't work anymore in calls.
The problem was simple: in calls or while recording audio on whatsapp and such, the mic didnt work. While playing back the recording, there was a slight noise, just as you would keep the record button pushed but not talk and let it record only background noise. I can't remember, though, if while in call and on speaker the mic worked.
I bought a used flex cable with mic, charging port and everything on it (of which I was told was new), switched the old one with it and while playing back the recorded audio you can hear an awful distortion with slight oscilations as where the words should fit in.
However, the other person can hear me while in call and on speaker, but the sound is very, very bad.
My guess is that the mic on the flex cable that I bought was broken as well.
I thought of going ahead an buying another flex from a more trusted seller, but I'd like to get some advice firstly.
I tried anything that could be done with the software, this clearly is a hardware problem. What do you think I should check? What could be broken besides what i already know?
Thank you and have a lovely day!
I don't know if this will help but this guy seems to have a similar problem you can try his solution.

Hey!
Audio rec and calls use different microphones, however, I believe your problems are due to the connector slot on the PCB itself not due to flex cables. Just visually inspect your flex cables, do you see any strong fold lines or torn sections? If not it is quite unlikely.
Regarding the connector slot, find some repairmen who is able with a heat gun and flux, who can lift things from a pcb without damaging stuff. They can either reposition it or replace it.
Best of luck and I completely share your pain.

Thank you for your answer. I know I'm replying after almost one year, but I have given up fixing the old Nexus. Maybe I will try opening it up again and checking what you said, but I don't think it is worth it anymore. I still power it up from time to time, just for the old days. Heh. ?

Main microphone not working

Hello, hope everyone is doing well.
So all of the sudden the main microphone on the bottom of the phone stopped working. So I can only talk now using earbuds or on speakerphone, and ran the diagnostics which said contact samsung, who put me in touch with some third party.
Does anyone know if it's something I could repair myself or do I have to take it in to be fixed and about how much would each cost.
The only phones I have repaired before ha a straight class no curve. And no longer have a precise digital hotplate.
Or are there a another things I should be considering here? I have tried to look to see if there is dirt or anything but even using a jewelers loupe I couldn't really see anything.
Thanks in advance!

What happened before the "all of the sudden"?
If there was dirt in the inlet channel to the microphone, the microphone should pick up muffled sounds during the propagation of a strong acoustic wave.
What produced the message on the screen you attached?
If it's a hardware defect in the phone then you won't fix it yourself cheaper than at a service center, because you don't have spare parts and experience.
Usually immediately before the repair you should be informed of the cost. Calculate if it is cost-effective for you. Sometimes after such repairs there are further problems, because the main cause has not been removed
If it was blown or had a puncture, deformation or dirt then yes there would be some distorted sounds but I have tried recording audio in other apps.
There is a very short like disconnection click when recording out of that mic. Doesn't happen when I record from the other mic. But does make the same click of I start voice recorder but then no voice.
Didn't drop it or get it or get it dirty. Maybe I got a little moisture on it whenever I take a shower, but really not much, and the mic sealed. If it was the pcb board for the mic, that's like 15-20 on eBay, and if it's the actual mic like wiring, or driver I would just need the part number for the mic.
The image on the screen is from when you go through: Device care, then diagnostics. It gives the options to test all the functions that make your phone usable. I did then I reformatted. Did the tests again.
Yes you are right they said they couldn't give a price but maybe around 150.
I just sort of like fixing things yet have never attempted removing curved screen and without precise temp control I would worry about the battery.
I have most the tools and have removed flat screen glass on a 3d printers base hot plate. But because of the curve I wonder if it would need something to hear the edge at the same time.
I'm also on workers comp right now trying to save some money and curious if anyone has had a similar experience or at least had success fixing hardware problems or curved glass phones
Also just figured out that I can use my earbuds with bixby but can not get bixby or google to do voice to text through my Galaxy buds
Oops sorry last night I changed pages to check something and thought my post was deleted
