Bad sound quality

[718]

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!

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!

[snorlax]

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

[katsj]

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:

Hey guys,

I cannot see the link to the pdf. I need to disassemble my Jam too.

Thanx, Martido

[martido]

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

[JackBauer]

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:D!

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??

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?

[JackBauer]

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 :(

BauerI 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)

[swedbass]

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.

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

[dutchiesmokah]

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 ;) )

[mlecho]

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????

[chuniboy]

Thank you A LOT, this afternoon i dropped my qtek on concrete steps, killing it. After opening the case (decharging the battery in the process), checking wires, and closing it again, it works! You saved me from breaking the damned thing open 'the usual way' (involving knives and big screw-drivers) and killing it permanently.

[ninakaira]

let me see this..i really need it too

[nasmith]

Hi All,

I just bought a used s100 and had the sound problem. It would cut out on phone conversations. I came straight here and found the excellent PDF (thanks very much for that), and I took the s100 apart.

Actually, I didn't clean the contacts, I found the two screws at the top of the unit to be - not loose - but not tight, if you know what I meen. I tightened them firmly and I could see the circuit board making better contact with the speaker connectors. It seems to have helped, but only time will tell.

Anyway, I just wanted to say thanks, especially for the great PDF.

Cheers,

Nick

i dissmantled the phone following the instructions , and ... 4 very small silver "contacts" and 1 small plastic shaped like "U" fell off.
I dont know where to put it , i cannot find them on the instructions, the problem is that i closed the covers and i tryed to open the phone, does not work, i also tried to charge it for 1 hour and the light stays red :(
Please assist ...

[jimiol]

problem solved.
The new cover is 2 mm shorter the plastic that makes the switch to turn the phone on so a putted a small paper and it works perfectly, the main thing is that the new imitation cover is 3 times better !!
