[Q] Motherboard problems - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all, I have a galaxy s4 which I have had no problems with, but I am having problems. I was getting a lot of static when headphones connected and only left side working so I bought a replacement headphone jack, while I was waiting for delivery also noticed that there was static through earpiece speaker too, anyway I have now replaced the headphone socket and still have the same problem, only difference is both sides seem to be working now but loads of static.
I am now assuming that it is the motherboard at fault so my question is can I replace the motherboard without any problems? I have found a few for sale on eBay at a reasonable price but don't want to shell out and find out it won't work.
Amy advice would be greatly appreciated
Thanks
Mike

I-Mate speaker blown

The speaker on my I-mate appears to have "blown". Sound still comes out of it but it is a bit distorted and the volume is low. When using a plug in heatset the sound is fine; so I do not feel there is an electronic or software problem.
So.... How can I get this fixed? Are there replacement parts available?
Thanks for any help.
btw, I am in the U.S.
How to fix it...
Hi,
I experimented sort of the same problem.
It turned out that it was the speaker connectors because they where not making solid contact with the motherboard. As you can see on the walthrough, the speaker is not soldered to the motherboard, instead HTC used a spring mechanism that conntects the speaker to the motherboard when assembled. Over time, some devices tend to loose this solid contact so the speaker starts to loose it's power and eventually fail. However, there is a way to fix it yourself if you already ran out of warranty and if you like to take things apart...
Here's my walkthrough: http://forum.xda-developers.com/viewtopic.php?t=8525&highlight=
Good luck!

Re: How to fix speaker problem
This is great Rayan !! I _will_ try it and let you know.
My speaker stopped working full stop a week ago. At least the vibrating mode is fully operational but, of course, this has nothing to do with the speaker's functionality.
A colleague suggested getting a bluetooth headset for operating the phone through it, in case there is no solution to the speaker problem.
I do not know whether anyone tried this alternative but if they have, I would like to know if it worked (just to get a feeling of whether there is a workaround solution too).
Thank you Rayan.

Headphone jack socket faulty...

I've been using my Touch HD for 8 days now, everything's been great until now.
The headphone socket has stopped working properly - I only get sound through 1 headphone when the jack is fully inserted, and only get stereo by pulling it out by 2mm or so.
Has anyone else had this issue, or does anyone know of a simple fix for it?
I bought this as an unwanted upgrade from someone, so would Orange UK (who it was originally from) or HTC would offer any support? I guess not, but wonder if I took it to an Orange store if they'd ask for proof of a contract or just fix it (any experience in this matter could be very handy!)?
Thanks for any help or thoughts!
I had the same problem but quickly realised that the jack needs to be pushed in firmly.
Works fine now!
Thanks for the reply. I don't think it's quite the same problem - on my HD pushing it in firmly results in getting sound from only one earphone, I need to pull it back to get stereo. I think a contact must have moved to the wrong position, not sure though.
Hi all, i just got my Blackstone last tuesday and i have the same problem. Only i don't have stereo even with the headphone plug a bit out of the jacket. Please tell me there is some sort of setting somewhere for single headphone speaker because i would really hate to return the htc blackstone for a failure like this......

Audio Jack Broken

Hello, today, all of a sudden, my audio through the 3.5mm started giving problems, until the headset stopped working at all, and wouldn't be recognized anymore. As I looked at the jack, I saw a small fissure across the jack, which seems to be directly related - but I do not recall applying extreme pressure to the headphone plug, so I'm sure it was not me.
It was purchased over a O2 vendor, and before I go and send it in myself, I would like to know what the chances of this being repaired within the warranty are, and if so, what repair-times are likely?

Replacement ear speaker - where to buy? Found one for my old G1...

I replaced the housing on my old BB Pearl, and my G1 (which was way, way more complicated).
I've got a Magic now, and the ear speaker is acting up. When I make a call, sometimes the ear speaker is just dead - I can switch to the speakerphone no problem, and then when I switch back I usually have sound in the ear speaker, but I suspect physical speaker damage because sometimes it'll cut out and I can squeeze the top of the headset just right and it'll come back. Crossing my fingers that it's not something else electronic in the board.
I want to replace it - and while I've got it apart, may as well give it a new body since they are only $10-$15. (wish I could upgrade it to the Fender body with the 3.5mm headphone jack lol)
Problem is, although I can find new housings all over the place (including eBay), I can't find the replacement speaker anywhere but some GlobalPartsDirect website, and they have a 5-unit minimum wholesale order quantity.
Any suggestions on where to look? Thanks in advance!!
Bump on this-
I had PM'd a seller on Ebay who said they had one - just waited over 3 weeks for it to arrive, only to discover they sent me a replacement speakerphone speaker.
I could not have been clearer with them that it was the ear speaker that was not working.
Any help is appreciated - I now need to resolve this urgently, as I can't use my phone as a phone, and I'm postponing all sorts of things that I need to resolve - of course the timing is such that I need to liquidate some things and I can't set up Craigslist ads because I can't talk on my phone. Please help!

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
