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.

hi, i got an imate jamin and i need to replace the audio jack were the handsfree pug in, do anyone know where i can find to buy this part please or if anyone had the same problem how did you solve it.
thanks guys!!
Dodgy Audio jack
My audio jack plug works fine BUT when I unplug the headset, the phone stays in headset mode i.e. no sound from the speakers. If I plug/unplug the headset a load of times it eventually goes back to normal.
Any ideas. My solution is never to use the audio jack!

I've had two M600's which have done exactly the same thing, both replaced by Orange, I've now upgraded to an M700 and unlocked the old M600 with a PAYG sim and guess what that one has now lost speaker sound so that three with the same fault and this M600 has never had a headset plugged in.
Has anyone else had similar problems?
i had the same problem othillo before it broke so be carefull cause your is about to brake too, i mailed imate and they said the only way to fix it is to send it to them in dubai.. not relally keen to send it there .. but till today i havent find ther part any where it seems that imate dont send out parts ... as soon as i find an alternative i will post it here..
Is this problem caused by the connector itself or is it something else? If it is the connector I can buy a new one at the local hardware store and modify it a little bit to make it fit in my S200, probably going to replace it with an 3,5mm jack if that is possible...
it is caused by the connector in fact htc the original makers of the prophet on there new models they changed it to a usb connector for the handsfree i changed my connector many times with regulas 2.5mm connector but the sound doesnt work properly. what it does it comes out with out bass then when you push the talk button on the handsfree sound comes out good. another thing i noticed is if when you insert the jack plug in the connector and you pull it out a little bit the sound comes better and the talk button works, i know for fact cause i tried it that its not from the handsfee cause i tried it on another device and work properly. the actuall connector for them is different from what you find to buy even if you plug in normal 2.5mm headphone sound doesnt come out right . if you manage to make it work and modify the connector please post it here so who got the same prob like me can have an idea how to fix it... thanks
Audio Jack
Here is what the problem is:
Audio jacks have what is called a normally closed contact. Each contact point actually has 2 parts. In the closed (no headset) the 2 part of the contact point make contact (shorts). This enables the signal to pass through the jack to the phone speaker. When you insert a headset, the 2 points open (break contact) and signal only goes to the headset.
I'm talking from experience as a sound engineer for over 30 years and this is usually the problem 99% of the time when it comes to these type of jacks. One of the contacts (usually the ground when no sound or mic at all) breaks or can no longer "spring" back. I haven't opened mine yet but fully expect this to be the problem.

hi jsapper, i got what you saying and your absolutly right .. the thing i replaced mine 2 times now been done by a technician who fixes phones/pdas the thing with the connectors i replaced the device doesnt work properly sound comes out with out the bass and the talk button doesnt work .. i guess that the original part got some extra connectors or most probably the pins are switched around..
do you know if there is any special connectors for them...
I have a similar pb with my S200:
After running tomtom during 2000km installed on my motorbike w/ a 2.5mm headset, sound seems to no work anymore (neither back or ear speaker), I suppose that vibrations against jack connector are responsible.
With a bluetooth or wired headset sound works.
I have soft/hard reset, upgrade to last WM5 rom, upgrade to WM6 rom, I have tried to get in/out a 2.5mm jack connector without any result.
The ring facility is working (w/ or w/o 2.5mm jack connected), so I can say that the back speaker is working.
I am looking for a solution too...
nb: I have my back speaker + screen replaced one time after 2months.
Dean.
Have you try resolder the Connector?
it was to damaged to be resolded
Hi everybody,
I aswell have this kind of problem from time to time.My solution is quite simple.You have to use the original 2,5" jack with the 3 black "dividings".(sorry for my english) This solution reduced the problem dramatically.If the problem starts now, just plug it in and out a few times and it should work again.
Cheers
Phone Jack is a mechanical mess ...
Same prob, used the headset, rear speaker dead. I opened the prophet, unsoldered the jack and found it misconstructed.
The body of the jack is plastic and not capable to withstand the forces of a plugged in headset.
There are two integrated switches - which - when headset is unplugged are closed and deliver the signal to the speaker. one of the switches does not close anymore when the headset is unplugged. My first solution was to unsolder the jack and bridge the contacts 2 and 4 as welll as 3 and 5.
The rear speaker functions now and I can use the phone.
Next step will be to find a jack solution on the market to finally solve the problem. I will keep you informed!
thanks buzzi will be looking in here... for your post!
i had the same problem with my audio jack and i searched many forums for a solution. the only thing i can say: if you really want to use it and you want go back in normal mode after unplugging, take a little needle. if you look at the audio jack (USB is left to it) you have to stick the needle in the right side of the jack somewhere an search for a little contact (the first time hard to find, the second time easy) and try to push it a bit to the left. so the prophet goes back in normal mode. it sucks but i didnt find another solution...except for buying a bluetooth headset and use software to hear music over that (for mono headsets u can use a programm calles BTAudioToggel, but make sure u use the Toggle software, because there is another one called BTAudio, it sucks because it costs money and doesn't work for me so well)

Friends,
My prophet has exactly the same symptoms. However, I opened up the phone and carefully examined the jack. It is crap, sure, but at least on my phone it is not at fault. I tested with a continuity meter and the contact mechanism was working perfectly. Those who tried this measure without success read the following thread:
http://forum.xda-developers.com/showthread.php?t=281331
In my case it is definitely a problem with the speaker, and it seems to be eqaully common. It seems that there is more than one problem dogging the speaker of ths model.
mine's got the small contact switch problem.
it started last night! SO Annoying. Plugging a friend's original 2.5mm adapter in and out solved it temporarily. Then it went again! I have only got a 3rd party 2.5mm plug, and it took me ages to trip the small switch back with that. I have now got a BT headset on order.
Can't wait for the newer design HTC headphone adapter as I have had this problem with 5 different devices! (Tanager, Typhoon, Hurricane, Tornado and now Prophet.)
would agree with hybrid the needle trick fixed it ran media player so i could tell when it was working again. it was mentioned before that using the 2.5mm adaptor with ibky 2 rings as opposed to 3 causes this problem. I can identify with this as i have been using my dopod h/free with no problems for months i use the adaptor to plug in my headphones one time and get a eap of issues!
i will adapt a h/free to plug in some nicer headphones!
Can i use the USB connection as a handsfree port on my prophet?
Cheers
Hi, Prophet's USB is not a USB hub and thus not usable for connecting external devices - only way is bluetooth ...
thanks buzzi
Hy. I have such a problem that if i plug in a headset to the jack output i have no sound. But if i unplug it, the speakers are ok. I have given in the phone for repairment, but they said it has no hardware problem. So what? I don't think it could be a softver problem because i have reflashed it for a million thimes after this. Can someone please help me?
I have reverse problem. I have sound in headphones, but no sound on external input/output. Except phone rings. Like headphones is always plugged in. It began after using usual 3-contact headphone jack (instead of 4-contact HP with mic). I have no idea what could it be (looks like a short circuit, but don't looks like one)... need extra help! Can't use my mobile phone and it's vital for me.
For sunnyRio there are two possibilities, one is the headphones, you might wel have a pair of broken headphones, try connecting them to another audio source (CD, mp3, computer, etc.), if they are ok then you could have a "strange" kind of hardware failure, I've repaired lots of stuff in more than two decades of work and I've seen the strangest things...
Your headphones connector might be "dirt" inside, it might be suffering from a false contact (very likely if you do plug and un-plug your headphones a lot), this false contact can be very hard to see, I even found a connector that has its pins broken between the PCB (printed circuit board and the connector itself), this was a tough one, this device (was a walkman) have passed by several repair shops first, the only way of figuring out was by desolding the connector.
Generally, inside the headphones connector there's a switch that disconnects the speakers while the headphones are plugged, once you unplug the headphones the speakers come alive again, this switch can even be a "simple" switch, one throw, one contact and can be switching some electronic analog switch, however, it could be necessary to take it to a very good technician to get it repaired, if you want to send it to Italy...
For alexkass84, the front speakers are not responsible for the phone rings, there's another speaker doing that noise.
Your problem could easily be a simple variation from that of SunnyRio or it could the speakers, same treatment applies in your case.
If any of you are relatively confident with electronics you might even tempt yourselves, look for the service manual in the wiki and go for it.
good luck!

I had the same problem few days ago ... and I also noticed that when I pressed the keboard with a little pressure, sound started working again. But whenever I inserted the headphones and pulled out after the use .. there was again .. No sound !
After few days when I had to change the SIM Card, I noticed that the battery was not fixed properly and after fixing the battery properly again, my problem never existed !
Try and let me know please
Regards,
Hassan
That wasn't battery. I'm often used to change batteries (I have two in case of uncharging), so I didn't observed such an effect (tried also to sqeeze keyboard).
So I bet it's the jack contacts. I need ideas how to clean it without disassembling the device (I don't have heeded screwdriver and havo no wish to give it in other hands). Also I couldn't find spare jack for 4-contacts same the headphones with mic. I didn't solved BT problem, so I can't use my Jabra 620 well (mostly I listening to music).
Now I have WM5 and gonna try broadcomm BT stack. Have anyone tested stack for A2DP with WM5? Can you give a link?
hi
i have problems with the 3.5 mm jack for music out put, somtimes the headphones doesn't work, one of them work properly and the other one goes off or the visa versa, can some one help me with how to fix it or replace it.....?????
Hello ashvirk, from the things that anyone who has some electronics experience can do, this should be one of the easiest, but remember that you're playing with a somehow expensive object, so...
First be sure that the problem are not the headphones, you might have some cable problem.
Go to the universal's wiki and download the service manual, get yourself all the necessary tools (torx driver will be the toughest to get), open it up carefully and using a good and well grounded soldering station, take the connector appart, being very careful to not to damage the pcb tracks; also verify if the jack isn't just having a false contact problem.
Finding the right jack might prove to be not so easy, beacuse this connector has 4 poles (normal stereo ones have just 3, L + R + gnd), L + R + Mic + gnd, and it will also have some switch (switches) to conmute the internal speakers with the headphones.
Be very careful as this jack can be SMD (surface mount device).
good luck
thyanx alot it will help
glad to help
Hello,
I have a Problem with my Xperia X1.
The headphone jack is broken and the device will always return to the headset mode.
So I can not hear anyone during a conversation.
I would like to disable the headphone jack completely. Is there a program for that?
Are you sure it is broken?
Does it still deliver sound to a connected headphone?
Usually the detection of an inserted headphone plug is done via dis-connecting a contact in the socket where the plug is inserted (it re-connects when you pull out the plug). The same dis-connection will also happen if some dirt has accumulated at the place where this contact is, so it stays permanently dis-connected.
Over time dirt creeps into all holes of the devices and depending on your usage and storage style that may have happened now. Try to get that cleaned - maybe it helps.
I have however also seen devices where the connector of the socket to the PBA is simply ripped-off - no way to get that fixed afaik.
Luckily one of the wizards here (ultrashot) also has an X1 (as I remember) and he did a lot of true SW hacking to it, maybe he knows a way to intercept the driver or has a hint which driver to de-activate. Mind that he is very busy with really important stuff - so a simple hint may be the only thing you may get.
@ John Carter I have had the same problem for months now, at first it took a couple of mins for the headset icon to disappear after unplugged then it turned to hours and now days if I'm even lucky . I just found this today: HKLM/System/State/Hardware/Headset 0 .This disables the headset but for me it still does not play sound out the loud speaker like I hoped, in locksreen( I use S2u2) mode the headset icon is gone but when in the main interface the icon is still sitting on taskbar or topbar. It really sucks to have to use a mic headset connector to call and answer voice calls. I'm still searching for answer hopefully somethings comes up. Edit: It's a hardware problem not software.
First of all thank you for your answers.
@ tobbbie
The headphone jack is really broken = (
I've already tried to clean it but that dosent helped.
Thank you for your tip. I'm going to ask ultrashot maybe he can help me there.
@ Viper89
Are you sure it's not a software problem with you device?
For the headphone jack is not so important. I would unsolder him. But I do not know if that would still work.
I had also tried to play with the \status key in the registry with the same (non-) effects. I guess you have to intercept/kill the signal from the HW/driver that steers the other parts into what they do. Not sure where the HW signal enters the SW stack and if that could easily be altered (e.g. by dropping a device-driver). You could play with the HKLM\System\Drivers\builtin branch and then go for headset or alike. You may end up with a non-booting device, so take care to back up in case a hard-reset is needed.
If you are willing to play with soldering (and have some skills), try to solder the contacts of the socket new to the PBA. My guess is that the contacts have either come loose on top of the copper part of the PBA (then you can re-solder) or they have been ripped of the PBA including the copper. You then have to guess where the copper-lines went and re-solder. Worst you can un-solder all parts, but this is not easy to do without decent tools. You may bake the PBA around the socket and ruin the device fully in the end.

No it's definitively a hardware problem. I have actually stopped using my phone for music now and instead my mp3 player. I haven't seen the headset icon for 3 days now so maybe I'm in the clear. I think every time I kept plugging in my headphones to listen to music it kept re-aggravating the headset jack so I figured if I stopped using it completely maybe it will stop messing up and so far it has worked .
