Bad sound quality

There was a thread here about that the voice from the earpiece is distorted. I experienced to have a similar problem. From the first day the sound was excellent but in 2 months it changed to distorted and then become very-very weak. At the same time the sound was good if a loudspeaker is on or if the hands-free is connected. Thus, I supposed that the contact becomes bad. To fix it, I disassembled the device. The *.pdf-file how to do that is included (33 megs). When the contacts were formed so they touch firmly the corresponding places on the printed board and the device was assembled, I heard nice voice from the earpiece.
So, in some cases the problem with the sound may be due to weak contacts. I suppose the contacts may become poor because the material for the outputs on the earpiece is not so elastic plus influence of vibration from the vibromotor plus influence of humidity.
Backup the system before disassembly because during this the backup battery may discharge completely!

Sorry wasn't logged on...

Thanks a lot I got this problem long time ago but I don't know how to disassemble it so I always try to shake it to fix ......

Great ! Very useful
Thanks

thanks for the guide..... very useful

Where can I find the 33meg pdf? I need to disassemble the device too...

That is what I thought th first time I opened my MDA Compact! Believe me I am the very first one I did when the device first came out! After lots of research let me tell you this:
IT IS NOT THE CONTACTS! IT IS THE SPEAKER! The membrane is of low quality when you open the device and "fixing" the contacts it will only make it to work for a few phone calls up to a couple of days at most! The speaker is burnt by the high amount of volume the motherboard of JAM gives to the speaker! If you want to solve your problem then you ll have to find a Nokia Center and buy a speaker for a Nokia 6610! Nokia 6610 and HTC Magician have exactly the same speaker! The only thing you have to do is to change nokia's black cloth ribbon on the top of the speaker with HTC's black rubber get it into your magician and there you are! You have a perfect sound again! My only advise is to use the call volume just a click less than the maximum volume so you won't blow away your new speaker!
I dissasembled and reassembled my MDA compact more than 11 times trying fixing the contacts with no permanent result! After replacing the speaker with a Nokias's 6610 speaker everything seems to work like a dream for at least a month now! :wink:
Its much more easier to get Nokia's spare parts than HTC's! The speaker cost me 18euros!

any chances you could post us nice pictures of these manipulations ?

I would love to do that but please I don't think that my magician could survive one more disassembly! :twisted: In case of replacing a friend's speaker next week who has the same problem I will make sure I get those pics! Magician is extremely easy to be taken apart! The only hard parts in the removing process are the upper backplate which has to be removed very carefully in order to be fitted back in its place afterwards and the front faceplate where you will need something very thin like a thin knife or even better a razor to take it away from the black plastic on the sides! :wink:

where is the link to the pdf
Hey guys,
I cannot see the link to the pdf. I need to disassemble my Jam too.
Thanx, Martido

Sorry, I found it. Just woke up....

Oh, thank god, I'm not the only one, with this problem. But first i have two questions? Will i loose my warrenty when i open the device? Can O² discover that i opened it?
Did this contact fix solve the problem entirely, or not? Because katsj says the problem is the speaker!
Thank you in advance, such a great community!

Edit:
I read the PDF File and i have to say .. this is simlply impossible! You can cause so much damage .... i dont know where to begin. One small mistake and you can't forget your PDA. I think this is highly to dangerous. Is there no easier way to solve the problem ... some ideas??
Or do the pictures lie and it isnt that complicated??

My sound disappears during call...
Strange, during a call after a few minutes my sound disappears. I can hear the other caller, the other calleer can't hear me anymore...
But now I found a strange solution: when I pull up the volume button n the left a few times (it was already at maximum!) my sound is back!
Has anyone the same experience or a better solution?

I think when you pull up the volume there is this small tone and you hear this tone from the loudspeaker.
After you hear the tone, you cant here anything again, right?
I'm driving really crazy, i loved this XDA Mini since this prob occured and i want to find a solution as soon as possible ! I really dont know what to do
When i push against sd-card slot from inside, i hear everything .. again, so this is just a really small prob ..
I hope sb. find a solution quickly otherwise ... i dont know

I think it's a contact problem, so maybe the problem isn't that small... I don't want to open my device.
I don't think it has anything to do with the ROM or with the software.
(I wish it would, then there would be a solution in the end)

I had this problem too and found a fix:
I assume that while you are making a call, there is no audio from the earpiece. While on the call, adjust the volume up or down with the volume slider button. if you hear faint beeps and faint audio right after the beeps, your earpiece is working but there is a software glitch caused by the headphone jack.
Reset your device. Make a call (i.e. to your voicemail) and make sure there is audio incoming. Connect the (wired) headset. Disconnect the headset and you shoud now hear audio from the earpiece. You may have to reconnect/disconnect the headset a few times.

thanks
thanks for the pdf. ill check it right away!

U ROCK
THX GUYS>>>U ROCK...........I was soo worried.....
thx again..

Thanx dudes for the nokiaspeaker tip!
Just received my on ebay ordered nokia speaker and within a few minutes I fixed mine magician thanx to the pdf & already gainted knowledge on this page!
I bought this phone a year ago for a very nice price because of the damaged speaker and now at last I repeared it just for €3,- (instead of sending it to Orange risking over €100; I`m Dutch ya know )

hi guys...pulling this one out from the past....my magician has all the symptoms above, but with no luck, the replacement speaker did not do the trick...any other ideas/details/downloads....anything to get the audio back???\
BTW, i can hear glitches of sound if i play with the volume tab. That is to say, if i push it up, i hear the tone "ding" and i can hear the voice on the other end for a split second! So i must be close, no????

earphone problem

ok this is a bit funny
handsfree earphone works,,,but the ear phone in the mda compact doesnt work
the normal sound speaker works,,just not the phone speaker
ok it works stuttery when i press up on the slide switch and i can hear the caller kinda stuttering
wierd software rpoblem i think
its not hardware problem as the slider makes it work,,if i constantly press up o the slider but then i hear the caller and the beep beep it makes to tell you its at full volume

My qtek s110 is doing the same thing after i dropped it, could i have knocked the contacts?
Can anyone explain why the volume slider would make it work.
Cheers

I think its a hardware prob only! Cz if the volume slider is getting the sound volume increased, you guys still couldnt get the full volume right? If so, its probably the speaker or its contacts getting the problem!

solution for no noise problems
Hey guys and girls, I also had problems with “no noise from the earpiece only.. and were puzzled with the problem for few days….until found the reason behind it.
As I am a lover with high-tech devices, I really wanted to fix this problem by myself (not prepared to pay few hundred dollars for repair from technicians).
I also want to contribute something on this site, as I have read great information’s from this site.
Here it goes.
I had this "no noise issue" problem with one of my device (have 2 sets of o2 mini) had no sound on the earpiece only (meaning speakerphone, hands free mic all works perfectly).
Now, to make everything short, I have done a great research with few personal technicians and even official technician from O2 Company and found the answers for this problem.
The fault actually lies with what is called the "Audio Daughter Board". It is a removable internal PCB that the speaker contacts to receive its audio signal from the phone. The board has a connector that is soldered to it which sits on another connector that is soldered to the main board. Both of these connectors can become removed from their respective solder connections usually as a result of a fall or physical impact. Usually all that is needed is a touch up of the solder points.
This Audio “daughter board” is connected with black connector at right hand side only, and the rest of the board with double sticky tape.
Most likely, the black connector has been disconnected to the “daughter board during drop of the device, as you need to solder the parts back (black connector has 14 legs, 7 on the left and 7 on the right) to get your earpiece sound back to normal.
I have done it, so can you (very small legs, so has to have delicate hands).
Now, mine works like a charm…. So happy…
After all, it was neither the programs, nor the legs of the earpiece, but the actual connection between the boards itself.
Hope my information helped.
Cheers
PS: I have updated my device to 2003 second edition with radio 1.13.00 but have no idea where to get pda programs. Can anyone let me know where to find such good programs?

It works!!!! Thanks

Your a genius
Hi im so happy it worked. I bought even a new speaker but this was noit the problem.
The internal speaker is now working but i found another problem with the ring tone liudness which i have to clarify now. So the serach will start again for me.
Again thanks.

Hi need help from all of u.
Hi my o2 mini have this problem, i can't hear anthing from the caller but they can hear me.may i know how to get the problem done, hope all of u can help me thank You.

bluehanul76
You really rock m8.
I was very doubfull that this would work. I have tried everything else people has suggested to no avail.
BUT I thought I have nothing to lose in trying you suggestion.
And it worked. It really worked.
Thank you very much.

Sorry for what am i going to say, maybe i did not get things clear...
How on earth can you solder the black connector both on the main motherboard and on the audio daughter board? Am just asking cause my magician had a broken earpiece and when i open it to replace it the phone died. Strange thing is that when i remove the storage card it comes alive again but no sound from the earpiece. So this solution is great although i had to make the question just to know how to handle things.
Thanks guys
Got it guys, the one connector on the main board was detached completeley and got stuck into the other. That is why i thought that it was one piece.
Man , i said to myself how come these people got it soldered , they must all have personal nano robots lol
Update:
Burned the small black connector tha sits on the main rboard
Any chance for someone to know what sort of PCB is this so i can purchase one?

Firts of anything sorry for my inglish but i´m portuguese and my inglish is a litle rusty.
I known there are a lot of people whith this problem and i had to. I tried a lot of things and i find a solution. The major problem of the this is that the black conector don´t conect very well whith audio bord, and i do a trick, so i thake a litle peace of cotton roll in powertape (like one that is on back of keybord) and a put it as way that when e close it make pressure in de audio border conector(in left of earpiece) agaist de front cover.
I hope I can help
enduromen

i have the same problem, and i will try to do as instructed. if it succeed everyone have a drink on me

Hello.
I have the same problem ina Qtek s100 but , like I dont know very well how to do look for the hardware piece that you send me the picture file because i cannot download it from XDA, it dont appear. If you send me to [email protected] I will be gratefull.
Thank you

XDA2 - various problems.

Had my XDA2 running on WM5 for a while now.
Yesterday, I noticed it wouldn't power on - so reset it and when it did power on the battery level warning was showing, even though it had been charged in-car during a long drive. The device felt very warm.
Since then, other issues are appearing. While on a call for example, the backlight started flickering randomly before the screen went dead. Also, the device seems to stop responding to key and screen inputs - although at times it is just extremely sluggish and will actually respond if left for a minute or two. After one reset, everything worked except no sound output - this then worked OK after yet another reset and it seemed to be fine for a few minutes. It is now sitting with the battery out after it crashed following another reset.
Had a search for similar symptoms, but not found much. Can anyone point me in the right direction? I.e. loose connection, memory fault, software issue?

sounds alot more like batt or backu batt issues

Cheers Rudegar.
Will search some more on battery issues.

xda 2 sound and sim problem
Hi!
Plese help me!
I have strange problem with my XDA 2.
I bough it 2 days ago. It was in O2 network.
Now when I unlocked it for my network (polish ERA-GSM) I saw that when I'm calling I cant hear anything. Person from the other sight can't hear me too..
XDA have sound becose I used media-player ando other sound stuff, thats why I think that speaker is ok. Microphone is ok too becose I can record animations with sound. And the cable speaker and microphone works.. so what cind of problem could it be?
1. No sound from main speaker and microphone when I'm dialing. (sound works corret only after hanged call)
2.Cant see any contacts from sim card ;/ (on other phone it is and works perfectly)..
So what should I do now? ;/
Plese help...

I've had simular issues with my xda II also like:
sound would come and go, this would coincide with the storage card also not been able to be seen. In my situation i tracked it to one of the ASCIC chips on the system bord and aplied some arldite glue to set the bord arould the chip regid it still miss-behaves but not as often.

sounds like some expert re-soldering would have been a lot better solution... but the glue now prohibits that and I do not know a safe way to remove the glue...

Universal can't hear when clamshell closed

I used to be able to receive calls while the clamshell of the Universal was closed with the screen inside. I prefer to carry it that way because I consider that the screen is more protected by the hard case. It worked fine for over a year, but now, when I hear the phone ring, pull it out and press the green button, there is no sound and the mic doesn't work either because the caller can't hear me even though they know I have picked up.
In order to operate the phone on receiving a call, I now have to spin the screen around and put the screen side to my ear.
Is this a hardware fault, or might a hard reset help here. I am a bit reluctant to do that because I'll have to reinstall my applications and settings.
Thanks for any insight you can bring to this issue.
Tony

I had a problem like yours, mine was fault of a couple of falls (always inside the case) that my PDA suffered, I had to open it and clean/tighten the speaker contacts, but in my case the mic always worked, this is, it was just my PDA (outer ear speaker) with the problem, the others didn't have that problem.
Hope it helps

Known Issue
This is a common problem for these devices.
The speaker's connections are very thin leaf springs that are prone to breaking off.
Replacements can be got for about £5 GBP. (~ $10 USD / €7 EUR)

Check the wiki for the relevant manual

I'm getting a similar problem. When I get a call or make a call, the person on the other side can hear me but I do not hear any sound. I have tried it with closed clamshell, both with screen inside and outside aswell. However, I noticed that when I open the clamshell and it is halfway to be either closed or open (meaning with the phone opened just like a laptop) , I can hear from the speaker outside.
I have been using WM6.1 ranjoo's ROM since last year and havnt had any issues.
Would like to know if this sounds like a hardware problem as my phone dropped a cpl of days before I started experiencing the problem.
Regarads,

Answering speaker - Problem

Hy guys.
I bought this nice HTC Magician and it has a little problem. Speaker at the back of case works very well( I can play music and all), but the small speaker at the front panel( above the screen) for answering the calls doesn't work... You can't hear anything...
When I turn ON Speaker(back side) I can hear the caller, but and everyone around me....
And I can also normaly use it when headset is on...
In the mobile service they said that they have changed front speaker and that problem is somewhere on the motherboard...
Is there any salvation for this...

Assuming the service centre have changed the speaker for a good one, and they have cleaned the contacts on the motherboard, then they are most likely correct that it is a motherboard fault. Quite an unusual fault as normally earpiece speaker problems are either poor contact with the board or a faulty earpiece speaker.
If it is the motherboard, then a repair is not economic and could turn out to be impossible in some cases. Clearly the sound circuit is OK in as much as you get output using an earpiece. However, there could be an amplifier fault or a simple crack in the board connections. Without testing there is no way to know.
You could dismantle and check the connections (often the speaker has springy contacts that touch onto the motherboard). You can tweak them out a little and claen the motherboard contacts. BUT, if you trust the service centre then it would be a faint hope. If you don't trust the service centre (sometimes they give excuses because the job would take too much time for the amount they can charge - particularly on older devices), then you could dismantle (Always risky - unless you are familiar with this kind of thing - it could end up worse than when you start!!)
Mike

Mike, thank you very much...
I supposed that they probably didn't check everything as they should. Because hey're not officialy service or even to have experince with this devices. When servicer saw Magician he said " Oh this is complicated"... That's why I think that they even don't know how to fix the speaker or that they have put ther right one speaker. I didn't want to give them device to testing because I saw that they don't have experince as I said.
So I'm taking it, nesxt week, to service where I know that people are professionals...
I'll give feedback what i've done..
