[HELP] No sound / no working Mic after changing the display - Nexus 5 Q&A, Help & Troubleshooting

Hi!
Last week I damaged my display of my Nexus 5 and therefore I decided to change it with this guidance, which worked really good.
But now I've the problem that my Mic and my internal Speaker of the Nexus 5 doesn't work anymore ....
That's why I thought about buying a new Mic and Speaker for my Nexus 5 to replace the "old" ones.
I found a new one on Amazon ([url=https://www.amazon.de/Nexus-D820-Lautsprecher-vormontiert-Schraubenzieher/dp/B01860TKSS/ref=sr_1_1?ie=UTF8&qid=1488146441&sr=8-1&keywords=nexus+5+mikrofon]Microfon + Speaker)[/URL].
But I'm not sure if I should replace this one.
Does someone of you had this problem also?
Thanks a lot for good tips and for your help,

Did you check all of your connections? It's possible that the USB flex cable was damaged during the repair process.

Is there any method to test if the cable gets damaged during the repair process?

All you can really do is examine the cable closely for any breaks.

But isn't it possible to have a look at any errors in an Log-file? Or to look in the output of dmesg?

[Q] Rear speaker no longer working

So I've been using the Nexus S for a while now(about 3 months). And the other day, after I plugged in the headphones to listen to music, the external speaker stopped working after I unplugged them.
It worked intermittently afterwards but then stopped all together.
I was wondering if anyone else experienced this same issue and if there is a fix for it other than sending my phone back to Samsung for a repair.
I think it's got to be a short in the headphone jack or something sticking since it was intermittent. That's the only thing I can think of since it hasn't been dropped at all.
Any help or a link to the rear speaker module part so I can do a direct replacement would be great.
Thanks in advance folks!
Have you tried plugging the headphones back in, then out again? This used to happen to my laptop, however since you said the speaker was intermittent I'm also thinking it may be a completely different issue.

This happened to mine and i found out it was some rubbish stuck in the earphone plug so maybe try somehow cleaning it out ,,, if not then maybe its faulty somewhere.
Mine happened the same. It started hearing the speaker's sound very rare and then it stopped working.... But then I blow into the speaker and the sound came back....
Yeah at this point after cleaning the headphone jack, and even tried blowing into the speaker I'm lust looking to replace the speaker part. No just the ribbon with the front speaker as well, but I am specifically looking for a replacement part for the speaker enclosure unit. So if anyone has any idea where i would pick it up, let me know or shoot me a link to it.
Thanks for the advice folks!

[Q] Speaker replacement

Hi all just wondering if anyone here has replaced the internal speakers on their TF? Yesterday I right speaker just died, if I kind of twist it sound comes back for a sec then off again. So I opened this thing up to see how hard it is to replace it. 20 minutes later everything open and do indeed find dead speaker. Does anyone know of where to buy the speakers? Will the speakers from their netbooks work? I personally don't RMA anything so I actually would like to fix it myself. If anyone wants to know how to do it I can help. Thanks
after the last update my speaker also died
Plz How did you replaced your speaker ????
Well I havent replaced it yet. I guess what I'll do is order speakers from the asus netbooks. I'll ley you know how it works out.
I pulled my speakers, unplugged from circuit board and removed from TF.
I found, ordered some replacement plugs and used 30awg to make a few replacement wiring harnesses. It seems the original speaker wire is thinner than 30awg - in my opinion.
I got two different sizes of replacement speakers to test. I have not even tested the originals with my new ($50 scope awg, another story) audio wave generator since removing the speakers.
I was planning to complete my speaker tests and mod the next time I opened my tablet. But, I am not sure when it will happen.

OPO motherboard replacement due to audio jack malfuction

Hi everyone!
Yesterday I had an issue with my OPO (a 16GB Silk White model). In particular: I was listening to my music with my headphones connected, when suddently the wire of my headphones got stuck into something and they got forcely disconnected from the phone. When I replugged them I heard a "fast thinking" noise (similar to the noise that you listen right before a call, when your phone is near to a speaker. I hope to be understood). I played a song and there were audio problems. I already checked the headphones with an other phone and they are completely fine. So I think that something bad happened to the phone. To solve the problem, it's necessary to replace the whole motherboard (because the audio connector is placed on the MOBO itself).
I looked around surfing the net and I found another one (a 64GB model) for sale (at an affordable price) so I was thinking to buy this one and replace the motherboard with mine. My question is, are there any problems on replacing a 16GB model's MOBO with a 64's? (I mean, electronically speaking (incompatible voltage, or current problems and so on...). In other words, is this operation legit?
Of course I'm opened to any suggestion and advice.
Thank you in advance for your help, it is really appreciated.
Cheers!
So the idea is to keep the battery, screen, camera module, usb connector, antenas and just replace the MOBO?
Since between the 64gb and the 16gb version the only difference should be really the storage size. I dont see any issue coming up.
Everything u are worried about is controlled by th mobo since every connector and chip is on the mobo. Plus the batfery on both versions are the same... The only problem u may encounter may be the camera if there was any revisions to it.

Speaker not working (after replacing the speaker as well)

Hi,
I replaced my Nexus 5 battery after it was showing signs of age, and now battery life is good.
However, after changing my battery, I have noticed that the speaker is not working anymore. Thinking that I might have damaged it during battery replacement, I got a new one off eBay. Sadly enough, I replaced the speaker with a new one and the issue still persists.
Earpiece works 100% and headphones work 100%
So I was wondering what to look for; any pointers?
Thanks
When you say "phone speaker works", you mean the earpiece speaker at the top of the phone?
Is it possible the USB flex cable was damaged?
http://forum.xda-developers.com/google-nexus-5/help/to-buy-usb-charging-port-flex-cable-t3314357
Yes. I mean earpiece, I am sorry.
The USB Flex Cable was also replaced; this was due to getting a static screen on my phone. As far as I know, the flex cable is responsible for charging and such but not for audio. I might be wrong.
Edit: The Flex cable was replaced around 5 months ago, not now. I re-assembled the cable to make sure, but to no avail.
I replaced half the parts in this bloody thing!
Regards
Mine had the same behaviour, is the flex female on the mainboard that connects between mainboard and speaker, check how to fix audio at youtube.
If u press somewhere behind ur camera u get sound?

I'm going slightly mad or the case of unsuccessful diagnosis

For some time I had problems with the mic, flickering display and non-responsive touch. I have opened the phone to reseat the flex connection and it has only worsened the problem: the display would not turn back anymore.
I have ordered a new flex cable and the problem persists... but I have a problem with diagnosis. The thing is the motherboard seems to work correctly, as I can find the phone with the Google site (although I cannot play the sound?). On the other hand, before the flex replacement the display would show colorful static, so it does not seem to be physically damaged by my repairs. What else could it be, then? For a while I thought that maybe it is the flex plug on the motherboard, but then the phone is seen as Nexus 5 through USB, so at least some of the data are going through from the USB port to the motherboard...
Without having another working screen, it would be tough to pinpoint the problem.
I do not have another working screen... or so I thought. I have connected the phone through HDMI to my TV and it seems to work, except it is very, very slow. This makes the screen issue more likely.
I agree.
Even a screen that shows scrambled images or static doesn't necessarily mean it's functional.
I've gone through this myself in trying to decide which to buy first: a screen or motherboard.
I have ordered a new display - no luck... It turns out it was the motherboard after all, more specifically, the port for the flex cable. It became more evident when part of the port fell off during the screen replacement...

Sorry to hear that.
I recommend looking for a cheap Nexus 5 with a broken screen and working motherboard for a cheap price.
