I got my Xperia pro just two weeks ago and since the beginning it started to show erratic behaviour in the loudspeaker as from time to time it stoped working and the only way to bring it back to work was two remove the back cover of the phone and then pushing over the loudspeaker piece.
As I had great need for the phone and its contents I deliberately decided not to send it for warranty ( my bad i know) but instead try to find a solution myself, so I take it to a friend´s and we unscrewed and retired the loudspeaker piece from the phone... so far everything just seemed normal, i found that there are two pairs of contacts on the pcb that make contact on the loudspeaker piece. Watching the phone from the back the ones on the left are the actual source of sound and directly connecting those to the loudspeaker (I split the whole piece open) made the sound come clear and fine, the other set of connectors on the right I couldn´t find what they are for. Since the phone does not seem to be bothered by having this piece removed i ran test with it on and so far every componente except the loudspeaker is working fine: BT, WIFI, GPS, GSM, 3G, Accelerometer, Vibrator, Mic´s, FM, cameras, brightness sensor, proximity sensor, touch, hardware buttons, compass.
The solution I found was tho completely strip the loudspeaker from the original contacts and make direct connection with two tiny cables two the pcb, IT WORKED!!.... but in the process I just broke the other pair of contacts, the one on the right (looking the phone from the back) so now they are not connected and whatever were they for is not working now, it´s just that I don´t see what could it be since every component I´ve tried so far is working fine.
If someone coulb bring further enlightment on what are those connectors for and what I broke I woul really appreciate. THANX XDA!!
Don't you have a valid garantuee?
EDIT: Oops, read over it.

Can you tell what the type-number of the Pro is (like MT15) for the Neo? MK15i?

I´ve aready check out that schematics but I´m too noob to figure out what is what and definitely I don´t know what are those connectors for.... So far I´ve used the phone the whole day and I noticed two things:
1. Early in the morning after playing music on the loudspeaker for about half an hour tho sound got distorted, after a little while and without my intervention it fixed it self and the sound has been clera and fine the rest of the day... maybe a loose contact?.
2. the signal strenght has been like a half of what it used to be. maybe those connectors are some kind of antenna?
Anyone willing to confirm that??
Another question. In your NEO´s do you have also those two pairs of connectors??
since the PRO and the NEo are very similar I would guess so but I don´t have a NEO to check it.
the model of the XPERIA PRO is MK16a
THANX forum!!
Update I´ve started tweaking with inserting aluminium paper to try and guess if it is an antenna and guess what??:
1. signal strenght without aluminium filling the holes:
-73dbm 20 asu hone alone
- 93dbm 8 asu :sandwiched between my hands
2. signal strenght with aluminium filling the holes:
-65dbm 28 asu hone alone
- 82dbm 15 asu :sandwiched between my hands
so what do you think??

I don't plan to open my Neo as long as it's under garantuee or working. I opened my previous phone (Sony Ericsson K330) to remove some dust. I touched some connector with my screwdriver and I saw a huge flash and some coming of it and then it died.
And that's why I bought a Neo.
well I understand nobody will be as dumb as me by open their brand new phones... hehe... anyway if you find a way to helpme I´ll be so glad... by the way aluminium paper folded seems to give me a pretty variable signal.... anyone an idea to replace it for a better component.... and yes I´already told the seller of the phone to look and see if he can find the original part for me.... guess it is´nt that easy in my country

A couple of days ago I updated my Xperia Neo from 2.3.4 Gingerbread to the newest ICS.Well today I woke up with 6 missed calls, because apparently the back speaker stopped working.Not even the slightest bit of sound comes out of it.
Headphones work, "call" speaker works, but the back one just died.I haven't physically "abused" the phone.I dropped it lightly a month ago, but I doubt that's the problem.
Repaired software via PC Companion - still not working, so it must be hardware.I haven't rooted the phone.Haven't tried any speaker mods/apps only the stock Xloud.
The phone is 1 and 1/2 months old and the speaker died already...what the hell is with hardware quality these days...
Any ideas guys?Please help.

most probably a hardware problem.. give it a service ASAP.
The problem is no SE authorized service in my country and sending it to another country just to get the speaker changed...I don't know.
Would it be expensive to find someone who knows what he's doing and get it changed?

yeah..maybe..you could try some help from the recognized contributors.. if its a hardware problem, try finding someone nearby..or just ask for an exchange where you got it.
Have you already tried the service test menu (*#*#4636#*#*)?
So music playback etc also doesn't work, how about touch feedback sounds?
You can also try going back to Gingerbread with flashtool.
Same thing happened to mine a couple of months ago. I sent it for repairs, and the report indicated that the speaker's metal contacts (?) became loose.
I've found people complaining about the same issue on another forum I use to go to. So yeah, unfortunately it seems that the device is poorly built...
i have the same problem here but not totally..
several moths ago i accidentally drop may xperia neo v and then there is a bit of change in sound.
sometimes it is so silent and then somtimes it is to loud.
but i think it's fix now..

I've had this problem twice - once I missed my alarm in the morning.
Solution was to gently whack the phone against something hard and it's fine again - I've got a case round it so no damage done. I got the phone secondhand so it could've been damaged before I had it.
try plugging in and out the headphones

Remove the back cover and try applying pressure on the areas near the back speaker. It happened to and this works
Here's how I fixed mine.

This is how i fixed mine:
---This is only for fixing the loose connector problem. Luckily, this was my case.
I need to clarify that you don't need to open the whole phone and take it apart. Just the right side panel (The one without any buttons)
1. Remove the back cover. (of course, your phone should already be turned off by now)
2. Remove Battery, sim card, and sd card.
3. Unscrew 6 screws at the back of the phone. (actually, you only need to unscrew 3, but just go with me now)
4. Remove the two plastic side panels.
Take note: side, not front panels.
(and actually, here, the only panel needed to be removed is the right one, the one without buttons)
5. look at the back of the phone. place it in a table in such a way with the speakers near you and the sd card slot away from you.
6. you will see a fine black wire running on the right side panel (after you already removed the plastic panel)
7. It runs from below the sd card slot to the right side of the speakers.
8. take a tool(preferably not sharp)
---The connectors can be seen because there is a small gap/hole where you can see the connector pins.
9. Now, use the tool (i used a small flat screwdriver) to push down the first connector (the one on below the sd card slot)
10. Next, push down the second connector (beside the speaker)
After that, boot up your phone and try playing some music. It should work fine now, if the problem was loose connection.
I notice that I'm a bit too late but i hope this helps anyone else who might encounter this problem.
BTW my phone is NEO V but i think it should be the same with your NEO's. Cheers! :fingers-crossed:
If u need a picture, you can private message me, or i can give u a link from youtube. Just search: disassemble xperia neo or assemble xperia neo. Both helped me in the process. Find the videos by mobi mobirout. That's it!
Update 1: Here's the vid on disassembly.
Update 2: @Pantamorph
Sorry I got messed up when I sent you those two messages. Check this new image, it's more complete.

Don't whack it you can try applying pressure as pinuno2007 suggested if you want it simple, or try the solution I posted http://forum.xda-developers.com/showpost.php?p=47544468&postcount=11
btiu idea
PLEASE DO NOT PERFORM ACTIONS THAT ARE DESCRIBED ABOVE !!!! THIS IS NOT A SPEAKER CABLE THIS IS AN ANTENNA YOU CAN GET ADDITIONALLY PROBLEMS WITH YOUR RANGE (if you damage this cable or connectors)
Hello,
A few days ago I dropped my phone, which caused the front speaker to completely stop working. I disassembled the phone and saw that the front speaker got its front disconnected from the back. Here are a few pictures to illustrate: (I'm not allowed to post links apparently, so here is the URL: imgur.com/a/0IGjm
As you can see in pic 6, I have drawn lines that (as far as I understand, although I'm probably wrong) represent the 2 options I have for connecting the wire back to were it was before the front disconnected (obviously I would have to do the same for the other end of the wire on the other side).
Unfortunately I have absolutely no idea which option I should choose, how I should do the connection (soldering?), or even if those options are completely incorrect and I should connect it to a different location.
The phone is a Sony Ericsson Xperia X10i. More information is visible in picture 1.
Any ideas on what I should do?
Thank you.
Hi All,
I'm not sure if this is the proper section to post this question but since it's Q&A, I thought it won't hurt.
Desctription:
My wife owns Xperia U and our daughter managed to spill couple of drouplets of vitamin C, on the part of the phone right above the "Sony" branding, not sure how you call it; "hearbud" maybe.
And now my wife can hardly hear anyone on the other end of the line during a call...unless she uses loudspeaker or headphones.
Actions taken:
I did wipe the fluid with a tissue, also powered off the phone and wiped that part with ear cleaning stick with alcohol and then dried it with hair dryer and powered the phone but that didn't seem to help.
Question:
I was wondering if anyone had similar case and what would be the recommended action to take at home, before I take it to shop for repair.
Many thanks in advance
Just wait for a day or two
When I happened on my e90 ( yes I used that brick type of phone)
I kept it in sunlight for 2-3 hrs
Bt still had some issue regarding voice quality
It's been few day now, since saturday and still the same problem.
Any other inputs?
Hi,
Have a xperia z2 and the backlight its off i see the lcd its ok i change for new one and have same problem.
The problem its in motherboard, i see in internet xperia z backlight problem but i have xperia z2 and not find any solution for this.
I think problem its a fuse but not have pic of fuses xperia z2.
Thanks at all! And sorry for my english!
it is a rough thing to do, but it is the only way..
I have the same problem, I found these photos online, but the big deal is how you are going to replace the fuse, it appears to be a surface-mount component, and where to find a new one anyway.. It is hard way for both of us, we'll not throw away the motherboard, heh sony..
If you dont care about working without a fuse just remove it and solder the two ends, you can remove it using heat gun or hairdryer. Or search for this video on youtube Surface Mount Soldering 101, I cant post links
dont forget to pull the battery flex connector first!
sorry for the late replay

After a few days the microphone of my new realme 6 stopped working. At first it worked perfectly and then it just stopped. I can not make recordings, voice messages, I am not heard when I call... All you hear are some cracks. I tried already a few things like factory reset, disabling 'hey google' ... I want to try to boot in safe mode but I keep failing.
Does anyone have a solution?
Meanwhile I try to get help from realme aswel but they are so slow and not very helpful so far..

Hm.. Strange I am using this devices for more than 2 months I pre-ordered it I am not having any similar issue might be a device fault. Keep calm and wait for the support or replace your device(which is a good option)
Maybe this is due to dust stuck on the mic hole, or there is a short circuit on the mic because of conductor dust, or the mic connection to the circuit board got loose, or the mic itself broken.
---------- Post added at 12:15 PM ---------- Previous post was at 12:13 PM ----------
But i think it was the mic glue are not applied properly, so its loose and the copper wire for the mic got loose and will make cracking sound.
