Hi all,
As i started servicing all pdas for a couple of monthes (only as a hobby, i fix them for friends and relatives), i came across one BA that gave me some trouble.
i got it to replace its LCD that was broken as it was dropped and thats very simple to replace it, so far so good. now it has two main problems :
1. no sound from speaker (even when in speakerphone mode), but there is sound in the stereo earphones (i plugged to the connector by the sd card slot). - i can only assume that a bluetooth handsfree device it will also work.
2. although the backup battery is fully charged, if i remove the main battery even for a brief second, when turned on, the BA acts as if i made a hard reset.
as for solving the problems :
1. using a digital multimeter, i managed to track the conductivity from the internal speaker through its connector, flat ribbon to the connector which connects to the main pcb - so there is no contact problem from the speaker to the main pcb.
using the help from WIKI, i went to site that has the list of all components and their description - the IC that is responsible for audio amp is a MAXIM's MAX4410 which is a stereo headphone driver. a quick look at its charasteristics and typical configuration and i understood that (assuming this is the IC that drives the internal speaker) the speaker should have one pin which is ground and the other goes to the amplified signal from the IC. neither one of the pins showed it has GND to it. so maybe there is a bad GND line to the connector.
2. regarding the backup battery issue i do not know what makes this problem.
I am sharing this info with you all with two ideas in mind :
1. to resolve my problem and know those devices hardware better.
2. because i am quite a while watching xda-developers and WIKI and i got the feeling that a lot of eforth is given to the software side of all those pdas (which is greate!!! keep going, this work helps lots of people and it shows al thos mega corps they are not the only ones), but the hardware is a bit forgotten and left behind. let me tell you this, there are many VERY simple mini projects i made useing electronics (i am an electronics engineer in my profession) that made my life easy . i am now investigating those instruments hardware as i have several ideas to develope useful accessories to my pda (like an external IR transciver to control IR devices like TV,DVD and to communicate with my laptop, and some other ideas) and i believe we can do the same info sharing as done on software side but on the hardware side.
I will thank any ideas, thoghts or commentsabout this matter. Yol.
For somereason, my phone is stuck in Headphone mode.
like on the top corner, it shows that my phone is still in headphone state.
the problem is that even when my headphone is unplugged my phone is still in that state...
...meaning that, without my headphones plugged in, the other party cannot hear me and i cannot hear them.
i tried soft and hard resetting the phone, but nothing works.
Everything else is working phone, it just that i cannot make a call, answer a call, listen to music without my headphone....
Any help or tips is greatly appreciated.
Thanks alot!!
it already happend to my phone.. what i did is i connect the headset again and did remove my battery and remove the headset then turned on the phone again and the headset icon disappears.
if your problem still continues, i guess you should go to sony ericsson for replacement it seems your jack is grounded or alike. i heard that the jack is somewhat tight and could put a groove in you headset male jack.
PROBLEM SOLVED....

apparently its a hardward problem...
I had the same problem. This is what i did put your headset back in turn windows media player on now start a song and pull out the headset. Now it should get out of headset mode. Thats what has been working for me twice.
The other thing to watch for too, and this was a big problem with the older model HTC/SPV Devices, is that the detection switch inside the socket gets stuck.
I had this happen many times on my various SPV's up until HTC Started producing models where the headphones plugged into the mini USB.
If it does happen to be the switch getting stuck, you can try plugging in the headset and wiggling it about a bit, or i found that a wooden cocktail stick was a rather good device, to just poke in and rattle about a little bit.

the stylus is good too.
Hi there,
got the same problem. Tried everything, soft- and hard-reset, cleaned the connector with some alcohol....
Just before i got in the mood to open the case to have a deeper look at the connector, i stumbled over here
This is what i did put your headset back in turn windows media player on now start a song and pull out the headset. Now it should get out of headset mode. Thats what has been working for me twice.

This also worked for me
As a conclusion, i think there are several reasons (as usual ) that lead to this problem.
It may partly rely on the connector itself, e.g. bad "on" resistance of the contacts or mechanical twisted in any way.
Maybe some of the internal pull-up resistors are to weak also.
Additionally the software driver may have some issues, to indicate the "plug out" properly.
I also had such issue on HTC universal once upon a time.
It was also partly software related. In other words some "plug-in-plug-out" loops while playing some music solved the issue on that device.
Anyway, this maybe called another weird bug on a winmob platform.
Thanks for the hint again!!!
Best regards,

It's me again
I wonder if these headphone problems had gone with the latest firmware.
With R1AA017 the "headphone mode" issue could be reproduced a 1000 times.
1. Today screen, plug in the headphone
2. plug out headphone, headphone symbol stays active
3. plug in headphone again and start WM player
4. start some music, plug out headphone, symbol is gone, sound from the speaker
EDIT:
As it seems with R2AA006 the "headphone mode" issue is gone.
1. Today screen, plug in the headphone, headphone symbol appears
2. plug out headphone, headphone symbol disappears
Works as it should!
Anyway, please report if you ever got these problems and what kind of firmware you are using.
Let's try to concentrate on stock images (R2... , R3...), otherwise this would get very confusing
Cheers,
scholbert
sent it back for repair ... this happened to me twice and i sent it back for repair and the problem was with the headphone not the phone itself
Hi it happened to me as well. so after few times i was pi.... off and i send it to back to SE repair centre. and i also claim a crack in case. and believe or not they fix it in 12 days. That means SE knows those problems very well. my advise is dont be shy and send it there , they will fix it without any hassle.
try to drain the battery and charge it back up.
I also sent it back. After 5 weeks the idiots at SE Service returned it unrepaired, charged me 40 €, and claimed that the phone was once opened (it was not).
Will now buy an HTC or Nokia. Never ever again an SE.
It Got Solved
Hi It's very simple take your stylus and insert it into the headphone socket and move very gently, It will solve the problem.
For me it had worked always.
Weird but works
Hi all
ive been having the same prob here ... :
phone remains in headset mode even after jack is unplugged.
have been trying:
turning registry entry
blowing (worked at very rare times )
stylus/ pin playing ..
till now, no good solution
my request:
is there a way ( cab install, registry hack) so as to disable the whole of the headset.. its ok if i dont use it anymore.. ! i want it software, like some sort of software to disable the headset module completely ...
awaiting reply.
thanks & Regards,
Yeah I think there is a way. If you search for when I posted about this last year I think someone says how to do it in the comments.
Lots of people seem to be claiming that software tricks can solve this problem. If that worked for you, that's a co-incidence. Even re-flashing a different ROM won't sort out a mechanical fault. Just go get a safety pin.
my experience about the headphone problem
First time, when happaned I was crazy, because I coudn't answer a call and the phone looks like was broken. I suggest,(not a big deal) to close the player program prior you disconnet you headphone or in radio panel mode, to swicth to speaker listenig first and then plug off headphone. Nothing else, don't worry
Well, since I'm using a new phone I've decided I'm going to open my phone up to manually fix this problem as for me, what happened was, a very tiny screw got lodged within the headphone jack. I managed to get the screw out but I think I damaged the connector responsible for signaling that a headset is plugged in.
I have one problem however, I dont have the security screwdrivers nessary to gain access so I'm wondering, if anyone know any tricks to open the phone up. I've heard I can use locktite to bond the screw to whatever I want to use however that would be something I'd consider if I cant think of anything else. Until then I'll try using a screw driver just large enough to wedge itself in place and unscrew but if anyone has any ideas or suggestions, please if you would be so kind.
In the meantime if I make any headway I'll let you know what happens. (Does anyone want to know anything if I do open it up?).
Ok I opened it up... Let me tell you it certainly was difficult. My phone had suffered the cracking problem which made it somewhat hard to take apart without it falling to bits but I managed nevertheless.
As I peeled away parts of the phone to get to the small headphone jack, I instantly found the problem, the little clip that performs as the switch to headset mode was buckled... I got some really tiny pliers and I managed to re-bend it however, the clip wasn't touching the contact switch! *RAGE*. So I play around with it a little more and realise hang on... it's moving too much, I then noticed that the clip was actually cracked *ANGER*.
So I decided... ok, off goes the clip. I permanently soldered the connection instead and hey presto, no more headset mode, of course this means, I can never use headset mode but that's not a problem for me.
If anyone wants any help, please feel free to ask . I managed to give the keyboard a clean also! (No more double presses or keys that dont respond either!).
With this goddamn problem, is it possible to connect stereo bluetooth with sound?

Answering the last question: YES it should work as bluetooth audio has nothing to do with the headphone jack and I normally used bluetooth headset with the headphone mode stucked
coming back to topic It seems it is depending on case more soft or hardware-related. in my case it was rather hardware, no mediaplayer/radio method helping and putting stylus in helped only two times.
So I used compressed air to blow through the jack and then cleaned it with the earbud head/material ONLY (as the bud does not fit in) on a wooden stick (but then you might have hard times to pull the rest of the budhead out)
Anyways it worked, so far after many tries to make sure it doesn't get stucked !
I guess in future WD40 may be even better
Man this phone is so good and yet so full of bugs !!
its been a few months now and still no parts for my xperia so i cant get it fixed.
i have been wondering if its possible for someone to make a cab to turn off/on hardware headset jack or forcibly use handset speaker when in a call orsomething?
BTW i have tried all possible fixes using the "search feature"
Are you describing the problem where even though there is nothing plugged into the 3.5mm jack, the XPERIA thinks you've got something plugged in? If so, I'm having the same issue and have found that a quick way to fix this is to take the stylus and wiggle it about at the bottom of 3.5mm jack. This clears it up.
well yeah that worked before but my jack is kinda broken but working
some of the metal in the jack is really loose and the jack has a small broken part.
I had the same issue where my headphone jack reported that there was a constant headphone plugged in, it happened after I plugged a damaged headphone port into the phone.
It took many hours of research and a very intricate and careful dissasembly to fix the issue. I meant to take photos, but my primary camera ( my X1 ) was in pieces at the time..
Anyway, there's a little connector inside the headphone jack that makes contact with a pad, closing a circut, if the connector is bent too far out of the way, it doesn't make contact, and the phone thinks there is a headset inserted.
If your connector is actually broken, you'll have to jerry-rig a wire or something between the two plates to force it to know there's nothing in, but then you lose all headphone functions.
I had to bend the strip of copper to -exactly- how it should be, and it worked out for me, my phone is back how it used to be.
I hope this is of some help to someone, if it happens to me again, I'll document it properly, unfortunately I was in a rush this time, so I didn't have time to prepare properly, I went gung-ho and ripped it to pieces to get it right again.
what about a "software" method of fixing this problem?
doesn't windows mobile support turning headset off, from the registry, for example?
while using radio you can still redirect the sound to the main speaker, (this option is available on the radio panel) something like this feature can help us, i think..
Same problem here. I have tried some suggestion over here but didn't work. You may try it: http://forum.xda-developers.com/showthread.php?p=4485113#post4485113
I'm tired with annoying wire headset and now using a BT headset to be able make/receive calls.
Hope somebody can help us before we send back for repairing.
It happened to me, simply insert a clean "cotton buds" and pull it out again. I think, a dirt just got stuck causing some hardware short circuit or something. Don't know....but it definitely worked for me. I have tried those hardresets, softresets, tweaks and unfortunately none of them worked.
try to drain the battery and charge it back up.
Sometimes would be nice to combine some of the threads because they refer to the same problem
http://forum.xda-developers.com/showthread.php?t=529449
Anyway from my knowledge there are two reasons for this problem.
You may guess
1. Hardware:
This issue had been described very often. Of course the jack is a delicate piece of hardware, which could be damaged physically due to some bad plug or violent force.
2. Software:
It's obvious that the connection is controlled by a piece of software.
I realized that the problem had gone with the latest update.
Maybe it would be helpful to know about the firmware version you got on your phone.
P.S.: Anyone out there who may add this issue to the wiki?

I've been thinking about this for some time as I have some nice headphones (HeadDirect RE0) that I use with my Defy. But I miss having a microphone (taking/making calls without too much hassle). So I thought of cutting off the headphones of a Nokia stereo headset and putting a 3.5 plug so that I can have an extension cord with microphone.
I searched around the net but didn't find a good pinout so I opened the Nokias. They only have a 470ohm resistor (if I remember well). I tried to rewire those (to get a button push) with no success.
So I opened the original Motorola headset (quite easy and with no damage) to find quite a circuit inside. I'm putting the a picture of the circuit here, maybe someone with more experience can help me. The circuit is quite small and as I have minimum experience with circuits...
PS: I was thinking of getting a third party headset, but at about 10 euros... kinda expensive to break.
Heh, this is how i modded my headphones - got Creative EP-630 headphones, but no microphone, and sucking (compared to senn) motorola ones.... ...and voila!
Take pilot/microphone apart --> solder out old connections --> cut new headphones cord somewhere like 20 cm from headphone -->solder them in to original connection points.
EDIT:
Ohhh... and the worst part was to carefully remove original rubber gasket around original cables which were to be removed, and pulling/glueing new cabling through it. But the effect is awesome - there is almost no visual hint that someone modded them
..and sound quality....
I was thinking that I could get away with it without taking apart the original headset, but it looks like I'm slowly getting there...
Thanks for your reply!
I have a sony headset with mic, but they have the old sony ericsson socket. Could it be possible to solder a 3.5 jack onto them. Are the even selling 3.5 jacks with 4 rings?
I don't know if you could find a 4-rings 3.5 jack? Check the closest electronic parts shop. Or, if you have a Nokia headset lying around like I had...
From what I've found out the mic and headphones work OK just connected to the respective rings*, but what I couldn't make work is the button. As you can see in the attached picture, there are a few SMD capacitors.
*if I remember well, from tip: Left, Right, Mic, Ground (Corrected: Left, Right, Ground, Mic!!!)
Cheers!
NO.
There is right:
Left, Right, Ground, Mic
This is my modification:
Hello
I got an I9000. A few days ago I dissasembled the phone to separate the glass from the frame to fix the "home" button.
I was able to remove it without breaking the screen and fixed it. When I assembled everything back together I noticed that the earphone doesn't work and I can't hear what the other person says in a call. If I enable hands free it works well (uses the main speaker of the phone) and if I connect headphones to the audio jack it works as well.
Microphone is working fine (using the audio jack or using the phone's microphone).
I tried to replace the earphone-audiojack-light sensor module and it still doesn't work. I tried 2 different ones with no success.
The light sensor / proximity sensor works good as well. So I don't think there's a damage on the motherboard or the socket itself.
According to the I9000 technician manual it says to follow a few checks for this module that I attached on the attachments.
The components it asks to check are:
U207 - IC-CODEC
UCP200 - IC-MODEM
HDC302 - HEADER-BOARD TO BOARD
Surpsingly I am sure those components are used for other features of the phone. For example the IC-Codec must be the audio codec used to play sound. Sound works perfectly on the other speaker and on the audio jack. IC-MODEM is probably the chip that holds the modem.bin firmware of the phone, so if there was a failure with this chip I think I should have no signal, and I do. HDC302, well, could be, I wonder why tho since I've been carefully with this and I have dissasembled this phone a few times already with no issue.
Could you help me? How do the tests indicated in the manual? I only have a multimeter, but not an oscilloscope.
Thank you!
Hello
Seems this is a tough question. Do you know where I could find information? Maybe another forum that it's more into mobile hardware stuff?
Thank you.
Hello
After checking the pins with a multimeter I noticed that the pins 11 and 13 from the earpiece were not in continuity. Replaced the piece (a few times because all of them were broken) and phone is working again.
Thanks.
