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

Dropped Magician. Sound stopped working!

I dropped my magician when i stepped out of my car. :shock:
The problem now it that my sound isn't working anymore. The back speaker as well as the ear speaker are both dead. I disassembled the phone, cleaned all the contacts with alcohol and bend the ear speaker contacts a little bit up, but still nothing. When i connect the headset i can hear sound and make a phonecall.
Another thing is that i hear a high frequenty sound coming from the screen. I only hear it when my ear is near the screen. Never had that before.
Maybe you can help me! I want my baby back working again. So if you have any suggestion i can try.. :idea:

My refurbished MDA does that [t-mobile replacement after my one 'went wrong [see below]']. I dont remember the previous out of box one doing it though.
Cant help with the sound problem - everyone seems to drop the magician though.. even me once[belt clip sucks]! and then my 2 other friends.

Since disasembling my phone, cleaning everything and putting it back together not fixed my problem I put the phone on my desk. It just layed there not working. Till this morning... i picked it up again and knowing it is not working but out of frustration I just try again. And to my suprise. It Works again! :shock: My sound is back?? How the hell is that possible... I tried shaking the device to see if there was maybe a lose contact. But how hard i shake the damn thing. It keeps working. 8)
Anyway, I'm happy again Only thing left is the strange sound coming from my screen, but I can live with that.

o2 XDA Neo no sound help

something weird just happened today the phone has no sound what so ever screen taps, playing music on speaker, incomming and outgoing call no sound no mic on both ends, the only sound I get is the ringtone when someone calls any clue?? I tried a hard reset twice but nothing only way now for me to make or receive calls is to use the headset then there's sound and mic.

after some searching the post I guess I have the common rear speaker problem I try opening it and touching the wire but no go I guess I have to send it back. Now heres the problem I'm in canada and I bought this in hong kong I have the recipe and everything and I pretty sure this has the standard manuafactory warranty but I have jester rom on this do I need to flash it back to the o2 because I'm sure I can't I have the G4 model and can't downgrade any suggestions?

After some tinkering I'm thinking that its the headphone jack thats causing it I think there might be some sort of sensor in there to let the phone know a headset is in and now the phone thinks that theres a headset even though theres none because when I recieve a call the ringtone goes off. I would open it but there 4 screws holding the plate together and on one screw theres a sticker that reads void if remove and I'm scared that if I'm wrong O2 won't fix it if and when they anwser my email.

I have the same problem with my Dopod 818 Pro bought in Malaysia. So I ended sending it to pocketctech.com for repair btw I am in Canada too.

how much did it cost no including shipping and is pocketpctech canadian or american??

fixed it kind of well heres my story after opening it up and having no idea what to do I put it back together got a little pissed and jammed a screwdriver in there now my my headset only has sound from one side, so I said F it and decided I was going to take it to a cell shop when I have time to get it fix since o2 asia is no help, when I was at work I was thinking what could be wrong I know that my speaker works and I'm sure there's some kind of switch in the headset hole so when I got home I decided to find a small pin and bend the front of it a little so it looks like a very small hook. after that I was jaming it in the hole (LOL) anyways I was right theres a small switch in there if you are look at in my view the screen is facing down the switch on the left behind a metal place, to my supprise my speakers came on yay!!!. But this is not the right way to activate the switch since if the speakers on and you plug in the headset the headset don't work lol you have to use the pin again to switch it back but then the speakers stops working. I did this a few times to confirm the switch is there but don't blame me if you try this and screw up your headset plug hole.

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..
