Loudspeaker not working after battery & mic replacement - LG G6 Questions and Answers

Hi, yeasterday I replaced broken mic (incl. charging USB port) and battery on my LGG6+. After that I tried and test if everything is OK and I found that loudspeaker is not working .. I dissassembly and assembly phone after that a few times, I checked every possible reasons for this problem, I gently cleared all connectors between board and mic part (and tried to use also old mic & USB part) .. but without any success.
Maybe it's related (and I'm not really sure, that this part is from LGG6) with this problem, after first dissassembly I found this little peg with sealing ring on my table (in attachement).
The size (lengh) is appr. the same as 11 screws holding plastic cover of board. It seems like screw, but it's a little thicker and without thread. Do you have any idea if it's also part of this phone and if so, where is this peg placed inside the phone? I have absolutely no clue, where is this part from ..

So, please give me any hint how to solve the problem with not working loudspeaker, I'd like to use my phone again :] .. Thanks!

How to repair the sound issue on Prophet
Hi
I could read a lot of posts on that issue and found this solution:
Remove the battery cover. Then the camera cover: to do so, lift up the gently the cover starting from the side of the battery.
You will see something looking like a fan. This is the speaker. the problem is with the red wire whixh connect the speaker.
Turn on your prophet and run your favourite MP3 song.
then touch the red wire with your stylus. The sound should come back. Insert a piece of folded paper to keep the cable properly fixed. that's all
Watch out not to wish to fix it too nicely, you could damage the wire !
Hope this help, otherwise a return to the service department will be necessary !
Hope this helps

Hay the paper trick works!
I went here to learn how to remove the flap to the speakers:
http://www.modaco.com/index.php?showtopic=240109
Well, my speaker had the voice coil broken... touching the membrane would bring it back to life but that is no real solution. I replaced it with a speaker from a used old cellphone with some minor use of hot glue to fix it in place and seal around it.
It works now just as new.
Nir
yeah it is a real Problem.
mine is broken twice in 6 months.
tried the paper thing. but it sometimes sounds weird and there's some hissing. maybe I did it wrong. so I tweak it a bit and just lost it completely. no sound whatsoever now.
went to the service center today. they said that they have a new batch of speaker which supposed to be better than the previous one. if anyone can confirm.

That's great, this fixed my problem. After I touch the red wire with my stylus, the speaker just works fine, don't even need a folder paper.

I'll try this one myself - my speaker just died again - it's been back once already.
Well, I followed the instructions above and now I have a working speaker again. A very low tech fix to a high tech device.
I have found a small bit of sponge does the job better than folded paper.
what is the type of speaker.
i mean can i use any speaker?
what's the best?
Mohammad, you seem to have missed the point of the replies in this thread. We don't know where to get another speaker from but we do know how to make the existing one work again.
oh, dude!!!
sorry
What a piece of ugly Speaker: O2 xda Neo!
Hay Guys,
I am suffering from this nasty problem since sometime. My brother has tweaked the speakers with a metal piece seem to work. However if I use speakerphone, it goes off.
Is there a permanent solution to this constant spurce of unhappiness.
Incidently I have been blessed with a on & off camera problem as well. I think I will never buy a DOPOD product in my life again.
My Camera has those colour matrix instead of proper images. Occasionally it behaves normally. I have tried hard reset already.
Any body? help !!!!!

I wedged in a piece of foam. That's worked a treat.
The manufaturing quality of HTC is bad
I also have the speaker problem. And thanks for all of you to suggest that sponge and folder trick. I did it and i have put a small slice of ear plug sponge. For past 2 days my spearker is working. But dont know how long will this sponge give my speaker lifesupport. I am sure after few days again its going to be problem. Hey,...... is there anyone in this thread who has used sponge/paper and the speaker is working for long time.. at least a year ?.
These HTC products seem really bad quality products.
that worked

motorola l7 speaker is too a candidate
It's too bad they saved on the speaker. Guess the manufacturer of the speaker had a very nice presentation @ HTC
Trying to download that pdf file, but it's not working :/ However I've read on other occasions that people talk about that motorola speaker as a replacement. Might be worth giving a more detailed look into that.
What exactly is the problem with the speaker btw? Did anyone narrowed that down already? Why is the speaker not functioning properly?
pdf
The file contains instructions to change the original speaker using the spk of a motorola v525.
I did it yesterday, and works fine, but isn´t easy to do it

Loose power connector causing no sounds

Hi, I've finally discovered the source of my sound issues, and its due to the power connector being loose (possibly from being dropped by the previous owner)... I've read around a few other threads and thought this might help others experiencing the same problem...
Is there anyway I can sort this problem though? I've bought one of those screwdrivers to open up the case to see if there is anything I can solder back in place... but any tips would be greatly appreciated
Thanks!
I'm posting this from my Hermes, so forgive the brief response.
1
How do you knpw it's the connector if you have not opened up yet?
2
There is a specific thread here with pics, showing the rear speaker connector - that in one guy's case was pushed loose by the stylus.
3
If your rear speaker connectpr is loose just push it back on.
4
Some sound problems can be caused by a faulty/failing speaker.
5
The front speaker has spring contacts that can be bent following a fall. These can be bent back into shape. If the front speaker has failed it can be replaced with a motorola model - there is a thread on this forum.

For a collection of dismantling instructions go to my web site in signature below. Scroll down to the loose stylus/keyboard part of the blog for links and info. A copy of the service manual is also available for download. It includes a dismantling procedure - more detailed than you need!

Hi, Thanks for your response!
Im pretty sure its the usb/power connector thats at fault, as it looks like its popped out of where its suppose to be and when the sound drops, if I try to push it back in/fiddle with it, the sound suddenly comes back on. Anything else I try doesnt work at all.
Im guessing that when the sound drops its because the device 'thinks' the headset has been plugged in, hence why there is no sound.
Thanks again.

No Sound Out of Speaker Unless...

I dropped my 8525 this morning. It didn't seem like it hit anything very hard.
Now I get no sound at all out of the speaker - including the phone ring tone - if the stylus is pushed all the way in. I can pull the stylus out about 1/8" and get the sound back, but then it won't fit in the case.
Do any of you have any ideas on how to fix this?
*UPDATE*: Edited because I've now found that it's not just the speakerphone.
I have a similar problem but i don't think i dropped the phone. (well, I've dropped the phone, a bunch of times actually, but not recently.) It just seems like the problem showed up out of nowhere. I tried soft and hard reset, updated the radio and SPL and ROM but nothing has worked so far.
I'm not sure if this may just be a hardware problem because i get no sound at all (no ring tone, alarm, touch pad sounds, sync sounds... etc. ) But when i plug in the headset i can hear everything just fine.
Any suggestions would be much appreciated.
Thanks
Simple - known and posted about problem. Your rear speaker connection is loose. It just needs pushed back on. (and by the way it's near the stylus end taht's why fiddling with the stylus makes it come on)
Here is a link http://forum.xda-developers.com/showpost.php?p=2001027&postcount=5 You'll see a pic of the rear speaker and it's white block and red/black wires.
In short the rear casing needs to be removed and connector pushed back on.
You may or may not find the stylus rubber block is loose. If so PM me and I'll tell you how to fix it.

HD2 internal microphone - how to replace?

Ok, so.. i have this broken microphone on a hd2 board and need to replace it. But.. the microphone is soldered to the board + a metallic shield over it, also soldered to the board.
I removed the original (broken) mic and the shield and noticed it has 4 contacts to the mothebroard. I don't know if it's a digital mic, or what type of microphone is it. I soldered a couple of wires to that spot and placed an external mic to test to see if the board is fine. It worked, but i had a relatively low gain on the microphone. I tried to solder a nokia mic inside, but failed because i heated the mic too much (microphones and heat.. not good buddies). I cannot fiind a direct compatible mic so i need to improvise something.
Does anyone has an ideea about what types of microphones htc uses on hd2 or similar phones? And how to safely mount it on the board?
hd2 mic replacement
Hi Bogdan. Can you please share your experience with the hd2 mic? I have the sae problem after keeping a hd2 board in isopropilic alcohol after the phone took a bath. it works fine noww but the mic has very low gain and I think it's diafragn was destroyed (or at least the glue) by the alcohol. I would like to change it to some other mic, but after I red what you wrote, that it has 4 connections i'm in doubt. Did yu manage to make a "transplant" and have ot working? Also, I have a problem with the screen orientation (internal gyro sensor ) meaning the screen won't auto rotate after i removed the metallic band from the bottom of the screen, that connects the front to the bottom of the screen of smth like this (GND). Have you seen that problem? Problem is it works normally on Windows mobile but doesn't on android.
Thanks.

teardown problem?

HI,
New to oneplus 5 forum.
I recently bought a used oneplus 5 with a broken screen.
I am reasonably familiar with replacing screens, and the odd modular parts of phones
So, replaced the screen and frame, put it back together, everything seemed good
Checked everything, all things seem to work, except for loudspeaker?
Headphone output works , but I get a clicking from the speaker.
Have tried another working speaker - same thing.
Have ordered another flex cable from motherboard to speaker in case thats the fault.
There are several contacts on the speaker and underlying module that appear to connect with the back case.
The back case has the headphone and usb charging port, and several electrical contact points.
So - does anyone know if the back case has to be clipped back into place to get the speaker working?
I am reluctant to try it just to see see because it is a pain in the xxss to get it off again without scratching my shiny new frame.
if anyone can enlighten me who has experience of this I would be most grateful.
pootler
YAAY!
t'was the motherboard cable
Solution found and thread closed at OP request
