No sound from Charmer - MDA Compact II General

Today the sound on my phone has stopped completely. Works through the headphones and bluetooth but nothing through the speakers and the mic doesn't work. Tired rebooting, hard resetting etc to no avail.
Does anyone know if this is fixable please?
--update--
Just threw the phone to the ground several times in sheer frustration and the sound is back perfectly. I'd still like to understand what caused it for future reference in case it happens again. thanks.

there is a switch in earphone jack,try using some kind of contact spray,there is some oxydation in it

Sorry, I don't know what contact spray is. Does it have a brand name and where do you get it, how do you use it and do I need to take my phone apart? Yes, the problem's back. Thanks

HELP! MDA Compact - Cannot hear out of the ear piece!

I have a strange issue. I can not hear anything out of the normal phone ear piece. The only way to hear a call is with the headset or the speaker phone. When i turn up the volume all the way it beeps out the ear piece and i can hear my phone call in the background. As soon as the beep stops I can no longer hear the phone call. I have tried wiggling the headset to see if it makes a difference, and it did not.
As a side note, when i got this thing, it is a T-mobile compact with an I-mate ROM load...i didnt do this, the guy i bought it from did.
Does anyone know how to fix this, or has anyone else encountered this issue before?
You got a lemon. Send it back.
I cant send it back. Anyone else have any ideas on how to fix this?

Problem is; there's a little switch in your headphone socket, when you plug your headset it turns off the internal sound, and when u unplug it should normally turn on the internal sound. But if the switch is locked, jam does not recognize that u unplug your headphone.
My solution is, plug-unplug your headset's plug (or something thinner) several times in different angles carefully to your socket while your jam is playing something. Till u hear the sound.
Mine is ok now. And I don't use any 3. party plug adaptors anymore.

There is an issue with some XDA where the headphone socket jams after using the headset, insertion/removal/insertion or jiggling of something in the socket often frees it, or maybe a squirt of switch lubricant.

DON'T DO THIS. Switch lubricant is oil based and because it's very fine and sprayed under pressure, it gets onto every nook and cranny. If it gets under your screen it will ruin it.

I don't see how you cannot send it back, unless it is stolen.
See if the guy you bought it from will do a refund. If not, try and find out where he bought it from in (e.g. nowicom or mobilejoker in Germany?), and get proof of purchase if possible. Email the original supplier with the serial number and ask if they can do a warranty repair or replacement.
T-Mobile now do the MDA Compact in the UK. Contact T-Mobile customer services and see if they will repair it. You will need to reflash it with T-Mobile ROM before you send it to them.
If no joy, try HTC themselves, who make the device. You can check your serial number and log a ticket on http://www.htceurope.com.
At the end of the day it's still covered by the manufacturer's warranty, so there's no reason why you shouldn't be able to get it fixed. Let us know how you get on.

I know. Doesn;t change the fact that it's really bad advice.
I bought it from a guy on ebay. He is asking me to send it back to him so he can get it fixed. I tried plugging and unplugging the headset but that didnt work. I will see if he can tell me where he got it from and see about getting it fixed.
Thanks,
Jason
Next questions, where can i get a t-mobile rom so i can get this fixed?

cruisin-thru said:
It isnt something that can be fixed by rom upgrade, it appears to be a hardware fault on the headphone socket, this can normally be freed off with a bit of patience, reference the spraying of switchgear spray, I have used this solution and it works to free off jammed switches and relays etc, obviously you do not drown the thing in the spray, you could spray the end of the plug and insert that and hope it will penetrate it also.

cruisin-thru - you miss the point.
If you send an MDA Compact to T-Mobile with an "unauthorised" ROM, they are perfectly within their rights to refuse to honour the warranty by saying that it has been tampered with and mis-used.
Similarly, traces of oil inside the unit could be classed as being outside "normal use" or the result of an unauthorised repair attempt. These are standard exclusion terms of any warranty.
Whilst switch cleaner may be suitable for large electro-mechanical switches and relays, it is *not* suitable for delicate micro-electronics like the MDA. Switch cleaner spray is designed to penetrate *everyhere* it can in the most inaccessible places - so you cannot just hope it won't get where it shouldn't. Not only is there a risk of it contaminating the screen or touch membrane, it can also permanently damage buttons and keys within the unit that commonly use conductive rubber or capacitance membranes instead of old-school "contacts".
Neither is it likely that the headphone socket would be jammed with dirt, grease, carbon or oxidation, like you would find on a old relay, when the device cannot be more than a few months old. It's not an old car! The headphone contacts are probably gold plated - but only to a few microns. Putting oil in there will damage this coating and simply as as a dirt magnet, leading to even quicker failure.
Jason's MDA is still under the manufacturer's warranty. Why risk that being refused by attempting a botched repair?

There are several threads on this forum pointing to the right places. Might be easier to let the guy who sold you it put it right though, as it is a fairly involved process and you could end up with a paper weight!
Or send it to T-Mobile or HTC and hope that they don't notice, or object to, the ROM.
I had this EXACT problem with my MDA compact a few months ago, but it went away after 2 days. Very strange. Try taking your SIM card out and putting it back in. Also try bringing the volume up and down.
Same problem
Just thought i'd share:
I had the thing for 2 days, then discovered the same 'no sound thru earpiece problem'. Offcourse they wouldnt swap the thing here... and now its been gone for 3 weeks...
apparently they ARE gonna swap the insides of the phone.... Go figure... they could have spared themselves the trouble by just giving me a new one right away...

Problem with speaker and mic

Today I lost the speaker and mic in my 8125. I don't know what's the problem. I can't hear anything from the speakers nor use the microphone. The headphones work but not the internal speaker. What could be the problem?
I need help!!!
Diego
Still no microphone nor speaker in my 8125. I tried restoring to original set up without a change. I think it's a hardware problem and I';m taking it to CIngular for a exchange.
If anyone can help, please let me know.
Thanks
Diego
exact same thing for me. had this playing music when i removed the head phone jack and was surprised to hear that no sound came out of the external speakers ...
now i can't even use the phone ... WTF?!?
Well, I contacted Cingular Suport on the phone and they're sending a replacement. Apparently is a defect of the 8125 hardware and many have reported this problem too.
@MeatPopSci
Contact your service provider to get a replacement.

Dont Worry Bro Its No Big Deal, Calm yourself down and listen carefully, The reason its not working is that when you insert the headphone jack into it (there is a small jumper in it which works through a spring so when you insert the jack inside so it disconnects the main audio circuit) so sometimes due to some dryness or may be somethingelse it doesnt connect back, I just recently fixed one Device with the same problem but since i know how to open it and so i did but for you, i guess the top priority would be not loosing the warranty and that you surely will once you tried opening it but ofcourse you need tools for that, so heres a small tip which may work, Open media Player, Play a song and than try inserting the jack back into it and take it out, do it with a little force, it may start working but that will still not be a proper solution to it. Thats all i can help, if there is still you need my assistance in understading the way how to open it than dont forget to drop me a reminder mail on my mail box and ill check back and will tell you more if it didnt work.
Thanks man, a replacement is coming anyway, but it's good to know.

first i thought software was the problem so after a soft reset followed then a hard reset both failed to restore the sound i figured it had to be mechanical.
so i basically did what you said till TOOL started playing via the external speakers.
needless to say i am very concerned that this $$$ phone is so easily made useless.
BTW thanks for the help!
No Problem! It made me happy
Well, im so glad my idea worked n yes u know for me if it stinks, its chemistry
if it hurts, its biology
n if it doesn't work,
its definately physics(electronics) lol
so i dont depend or trust electronics
Anyway the pleasure was all mine, no need to thank

HTC not vibrating anymore

Hello to all,
I have a HTC 3600 with the rom “Karmba_a 7.2 eLiAs EN-20000” for a long time and everything was working great, until last Friday when it stop vibrating as it was suppose to do when receiving a call.
After trying lots of things I decided to reflash it. And it’s still the same, does not vibrate.
Does anyone have any idea what might be the problem?
Thanks in advance
try change motor vibretor or see if there are humidity in bord neer the contact. it´s an easy operation

Changing motor vibrator needs to go to repair.
How can see bord to see if there is humidity? Does not look like a easy operation.

it may cause of the loosen screw which stick the vibrator with the phone. I have this happen before, you can try open the case and screw it back or take to some repair shop.

Thank you enduromen and ctrlaltdel.
Well, I'm having the same problem again, sometimes vibrate, sometimes don't.
And I can hear something loose inside the phone maybe it's the screw that stick the vibrating motor.
Can anyone tell me if there is a tutorial for opening the phone and check that out?
Thanks in advance
please me too ..it stoped vibrate

take a look
unscrew (inside trinity 1.jpg; screw circled with red) and open the cover, then you will see the vibrator and the screw that stick the virbator with the MB (inside trinity 2.jpg; circle with red). Screw it back and done.

Thanks for the suggestion
I've tried flashing a new rom, as well as trying a different headset... same deal
(I however haven't tried if those headsets work with other phones... so I'll try to do that next to make sure I'm not unlucky to the point where both mics dead)
Had a similar problem today--erratic vibrating and occasional strange noises. Thought it was the ROM that I had just reflashed but thankfully stumbled onto this thread - it was the very loose screw! Thanks for the advice.
Just to add a little levity, here's a solution that you probably didn't think of and most likely wouldn't have thought you needed. But... it's a funny idea, nonetheless...

My trinity also stoped vibrating.
Same here, and fixed it now.
Thanks astroganger for asking this question.
And everyone how answered

One word of warning: There's also another screw under the stylus. Don't forget that one when you dissasemble or it might break.

The tool needed can be bought at most electronics stores, ie: Radio Shack, etc...
It is a #6 Torx driver. Also called T6 Might find it at Auto Parts store, but not sure, it's pretty small...
It seems the stopped vibration is almost always the loose screw. Mine fell completely out and was wedged against the vibrating motor, stopping it's rotation. After the phone was open, it was an easy fix.

umm problem with the internal earpiece

what should i do i have the tmobile wing and speaker works everything works accept the earpiece thing if i put the phone on speaker i can hear the people but when i put it to work on the earpiece thing inside the phone i cant hear anything so how do i fix that and where can i buy another one THANX

I would try to find one on ebay that's broken and yank the ear piece from it.
ok thanx but can i use a headset or a bluetooth thiz way ti will make life a lil easier for me
If you have about 70 bucks, dr. cell phone will fix it. or if its still in warranty, call tmo
sigh no warranty this phone is about 1 yr old sigh....so where can i find this dr
google dr cell phone. they are slow though, just to warn you. took mine like 2 months because the part is rare
The earpiece speaker is really simple - two wires connecting to the plug - that sometimes can have a break in one of the wires. I had one recently that had the black wired severed completely because it got in the way of the screw hole. Might be worth taking apart and checking.

No sound

My Hermes doesn't do any sound until I connect headphones.
Is there any way to find out where's the problem?

Hi
There are lots of threads dealing with thisproblem.
The first thing to do is ruleout a software fault. Do a hard reset. (use a full backup program like SPB backup first if you want to avoid losing all your installations and settings).
If the problem remains then you may have "contact" problems with the front earpiece speaker. (Not sure if you are getting sound from the rear loudspeaker?). Anyway here's just a couple of existing threads that describe the fixable problems with both speakers:
http://forum.xda-developers.com/showpost.php?p=2001027&postcount=5
http://forum.xda-developers.com/showthread.php?t=288728
One other less likely but possible problem might lie with the USB port. (However I feel it's more likely a speaker issue).
Mike

I'm afraid of breaking the VOID stick.
But it's HW problem with the front speaker.

Well yes, if you have a warranty that you can use then do not break that sticker! It crumbles into bits very easily and they'd know you'd been inside even if you can get it off in one piece.

Ok ... now i connected Herm to USB and sound works. o__O so what's wrong with it? ((
i know I'm maybe acting little dumb

Well if you look at the last line in my first post above, you'll see that a fault could lie with the USB port. This is because the USB port is linked to a switching circuit to divert sound from internal speaker to a headset. If that is damaged then sound may not be reconnected when the headset or any USB plug is removed.
So is it now working or does it only work with a USB cable plugged in?
Mike
I unplugged, it worked. Then I did softreset and now it doesn't work even if I connect it to USB.
pajousek said:

OK two things to try.
Visually inspect the inside of the USB housing. It's very small but is there any sign of the fine wire contacts being bent or crossed over? The best you can do to solve this is to use a pin and straighten any that are out of line.
If that looks fine then I think we just need to rule out a software issue. Unfortunately that means a hard reset. Hopefully you have full backup software, if not you will lose anything you have installed and settings you have made.
After a hard reset you ust try the sound BEFORE restoring any backup you have made.
There is a small chance that repeatedly inserting and removing a USB plug will sort the problem - but it's by no means certain. It's perhaps something to try first. Also try wiggling it a little. If it's a slightly bent contact it may straighten it. If it's a broken board contact it will not sort it (long term at any rate)
Mike
I have done hardreset, but it did not help. Wiggling and reconnection too.
Housing looks fine, but i'll check it out in the morning.
So maybe it's really a mainboard issue? (
I woke up and I got an idea. Is it possible to make app, that would DISABLE headphones and point all audio to speakers?
hello, i seem to have the same issue.. i have tried all thwe things above... not working.. i can only assume the phone is broken inside!
although sometimes it comes on.. randomly.. i can only think that there is a broken connection to the built in speakers.
i'll keep following

Have you dismantled and checked those connectors or have you just done the hard reset etc?
The most common problems are the reare speaker push on connector has slipped off, or if it's the front speaker the contacts need tweaking out a little.
