earphone problem

[doctorforsh]

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!

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?

Hi im so happy it worked. I bought even a new speaker but this was noit the problem.

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
