Need help: Where is the microphone ? - MDA III, XDA III, PDA2k, 9090 General

Hello. Have problems when calling, I can hear the other person, but not the viceversa. So I think is the microphone.
Can someone tell me where is the microphone located ?
It can be changed ?
Where can I find one to buy or something compatible ?
Thanks !

you can prob find it here

Thanks a lot, I looked and the best information was "bottom", this was predictable because you speak in it and can be somewhere else but bottom.
I am not worried about the finding problem, but if you can tell me if it is hard to change, you can change it without breaking any wires and after you need to put it again to their places ? I am asking because I don't have the tools for this kind of operation.
Nobody changed the microphone to a Blue Angel ? At least I need a genuine Blue Angel microphone ?
Regards!

Hey there, You just need a T6 Torx screwdriver to get into the case and the microphone is a small metal unit that slots into the case and has two wires leading to it.
I took a BA apart for the first time this week and it's really easy. Swapping the microphone is as easy as undoing 6 screws, splitting the case then swapping the microphones.
If you're stuck for a replacement then let me know - I'm currently ripping apart a BA with a motherboard fault. The Mic is known to be good.
Cheers!

Maintenance manual for universal? or may fluffcat1 help me?

I think that i have read somewhere on the internet about maintenance manual for universal, may anyone has it or its link?
If no, how to disassemble my universal, the LCD coaxial cable is damaged, and i cannot hear the sound from the side speakers (the media files or ringtones) hear only the sound of call from the ear speakers on the screen side. I have read a thread before from fluffcat1, he said that he knows how to disassembe univresal and also how to repair the cable if the damage is minor which may be true in my case. Please help me, the new cable is too expensive in my country. Thank you very much in advance.
37 views aND ABOUT 3 DAYS WITHOUT ANY REPLY, I HOPE FLUFFCAT1 WAS NOT AMONG THOSE VIEWERS.
Anyway, this is my experience, may it beneifit anyone here. I decided to open my Univ. downloaded the service manual from the internet and dollowed the steps to tear it down. I didn't completely dissassembIe it, I found that a main part of the cable exposed after removing the base of the device, I fixed that part wirh a piece of paper, and i think the device is working good now, except for sporadic call drops. Do u think that this drop is attributed to the cable, or as I think it is a separate issue?

UNIVERSAL : need a Coaxial Cable Pre-assy replacement

Hello
I am new on this forum, sorry if this type of question has alreday been answered.
I've got a UNIVERSAL/ SPV M500 and the Coaxial Cable (linking the screen and the keyboard) has been twisted and is damaged.
Where can I find/buy a spare part to replace it ? the reference number is 73H00233-01M (Coaxial Cable Pre-assembly) as indicated in the service manual.
Thank for your help.
Hey,
If you find it let me know, I need one two. Actually these are two cables the Coaxial (Display) and Coaxial (Functional). My screen goes white in landscape mode and I confirmed it's the cable by disassembling my machine. However was unable to find that cable Will let you know if I find it.
Me too.
I am getting odd touch screen errors and think it can only be the cable.
If anyone knows of a supplier, please post here.
Has anyone tried contacting HTC directly?
I've tried HTC europe , they forwarded me to the local repair centre. this one do not sell spare parts without repairing the item.
I'm trying to contact various shops . I'll let you know if it is successful

Give this site a look, http://www.apexlaptops.co.uk/Universal.htm
I have been having the same problems as you guys. my uni have been getting "white screen of death" for about 6 months now.
I am going to take out the cable and try and fix it myself. (fingers crossed)
I will let you all know how it goes. I felt £60 plus vat and postage was a bit steep.
coax cable
Fixed it!!
I took apart my uni down to the last screw, and rebuilt it.
In the process I did find that i am missing an antenna in the back, it should have 3 but only has 2. oh well it works.
The 3rd antenna is for 3g and i am not on 3.
Anyway back to my uni.
The coax conectors where a little lose, so after a good clean in a solven cleaner and popped back in to the conector holder, after playing for 20 mins I found that they poped back out verry slightly, just enough to make the screen go white and not function.
So the solution is to make sure it does'nt come back out.
ok.
well I have as a tempery solution put a tiny bit of foam on top of the connecter and held it in place with a bit of tape.
If this works for longer than a month then i will solder the cable down.
Touch wood it seems to be working. I will try and get some photos done tonight

re: fixed it
Yes just a torex screwdriver size 6 to take out the 4 security screws in the battery tray, watch makers screwdrivers and a pair of fine point tweezers.
still having problems with my camera so photos will follow when i take it apart to solder.
ang how about antistatic gloves?

Anti Static gloves!!
Because of the Job I do, I have an earthing band to connect the phone and me to the wall, and put the phone on an anti static table cover. All is good so far. I am looking at Feb to solder (as i have some leave in). There will be detailed photos and description.
Untill then........

Good done man go ahaed, and plz try to post the photos.
Another question, my universal some times lost its external speaker sound, so i cannot hear the rings, when i press on the back of the device, exactly on the battery cover in the middle between the two dummy holes and the usb port, it works again. Do u think that this is due to the coaxial damage also, even i don'y have any problem in the screen??

I have disassembled my uni and checked for all connections, but there was no improvement. I can confirm that the disappearance of external speakers sound is not due to co-axial cable. The proof is that i extracted my main borad from my uni and implanted it in another one, i assumed that the problem will be rsolved, but the same problem still exists. Ok, now i can disassemble my uni for smallest piece, but any one advise me where is th connection part or the piece that causes that problem. Again a brief description of the problem:
when there is a coming call, i cannot here the ring or it is sevrely intermitent, also when i play any WMP file, i cannot here the sound, if I press firmly on the base or around the keyboard the sound comes again and may last for a few minutes or disappear after another press. So, there is a lose part in the main board i think that needs fixation, but which one????
Hi all
Now it takes me more than a month to upgrade my JASJAR due to a lot of problems I faced during this upgrading adventure… anyway, the last problem I still have is that after upgrading the screen goes crazy, I mean if you press on the screen the colours are mixed for few seconds and then its ok but at any time I touch the screen again the same happened so you can imagine what if I am going to dial a number or write a message …. So can anyone advice me what to do? …
The rom version is 1.13.82
Radio 1.04.02
Extrom 1.13.188
And I think the bootloader 1.00 and I don’t know why I feel that the bootloader is the reason ... I made a deep search but I couldn’t find problem like mine

Sitting next to my M5000 and all of a sudden the screen turned on but was white!
Following your lead I found that the first i.e. 'underneath' connector was not fully home. A little push and all is well.
Took the time to pack out the housing for the stylus to stop the little blighter escaping whilst in there.
Thank you for taking the time to post gingerchristopher.

Help! I need to find a replacement earpiece speaker.

I was able to get my Kaiser after someone at my work dropped theirs and since AT&T won't cover damage they ended ordering a new one and I decided to replace the screen which was BADLY broken but otherwise worked. What I didn't know was that the contacts on the earpiece speaker were being held in be the case.
I am looking to get a replacement 'earpiece', aka conversation speaker, for my Tilt but I cannot seem to find it anywhere online including ebay. So far I have found a few repair shops that would be willing to fix it if I send it in but as I have already successfully replaced the LCD I prefer to do the work myself. Does anyone have the part they would be willing to sell me or know of a company that would sell just the part. I have a bluetooth headset but it would be REALLY helpful to have the earpiece speaker working again since windows can be flaky when it comes to answering the phone using the headset.
if your going to do the work ur self ur going to need a soldering iron and possibly an ohmmeter (electrical evice measeuring electrical resistance ect) u would need to ohm out the speaker in the phone and u might be able to use a headphne speaker if u used a resistor with a head phone to get correct ohms for the speaker to work beacause u need the same ohms or it coul draw too much or too little current from the amplifier and the battery and if that doesnt work speakers in commercial devices are usually genaric made in korea or china u could try speaker from a different phon hopefully a cheap phone, hope i helped in some way
din,
Not looking to fix the component.
I was hoping to just replace the actual component, as I am not trying to fix the broken speaker or try to fit a different speaker into my phone. If I can't find a place to buy the speaker I probably will have to get my work to but me a phone and it will likely will be a Blackberry as that is our corporate standard.

Help... Internal Speaker Died..

My internal Speaker died today... while other speakers still perform normally..
What's the possible cause of this issue? Wanna fix it myself.. Thanks alot..
There could be several reasons for this problem, one, have droped your PDA? Even if it wasn't recently this is one of the main reasons.
What about the weather? Some drops of water at the right place are enough.
The flex cable could be another reason and there are several more.
Do you want to try the repair on your own? Go look out for the uni's service manual (you should find it somewhere here at the forum), if you can't find it, let me know, I think I must have it somewhere.
Get yourself the torx screwdriver (mmm, I think is T5, but not sure, verify this by yourself), open the PDA and verify the speaker cables, begin by opening the display side of the PDA, be very careful when you open it, verify the things I've said first and perform a cleaning of the speaker contacts (the speaker itself and the pcb contacts), my uni had this problem after a couple of drops even if it has always been inside its case.
Let me know if you need any help.
Good luck
The case is not too difficult to take apart, but you need a precision screwdriver set with small philips and torx plus a plastic case opening tool (spade end, you probably could use a knife but may mess up the case). I have just rebuilt mine and have a few spare parts including a couple of speakers (the ones that go in the main keyboard side of the case). Let me know if you need a new speaker.

how to replace microphone in HTC s620?

I would need help with my HTC s620. Sometimes the mic works perfectly, sometimes it does not, so people on the other end of the line can not hear me at all or just very-very low. I already tried changing regedit and also used the audio gain and microphone fix .cab files, but the basic problem remained: sometimes the mic works, sometimes not. I made soft reset / hard reset several times, still the problem remains. With my bluetooth headset I always have good voice quality even if the mic on the phone is not working. Altogether this drove me to the conclusion that I need to replace the microphone in my HTC s620.
On Ebay I can buy a new replacement microphone for a few $ but I don't know whether I would be able to replace it on my own. Anyone has any experience? Do I need any special tools for replacing the mic in my HTC s620? Can anyone provide me with a guide how to proceed? Any help is much appreciated.

There's a guide for taking apart your excalibur in the sticky, but honestly it doesn't specify how to change your mic but it will give a pretty good idea of what tools to use to open and re-assemble your dash.
Thanks for the response Mr. Clown. Indeed I would need a bit more specific info on how the MIC is attached to the phone and with what method it can be replaced. I read some forums on other type of phones where only the manufacturer is able to replace either the mic or the full board when it is impossible to replace the mic. As I mentioned earlier on Ebay there are two offers recently on OEM HTC mic for s620, however some forums also mention that even if a separate mic can be purchased, it does not guarantee that it can easily be replaced. Unfortunately I am not a tech expert, so I appreciate any guidance on this issue. Many thanks.
some possible solution
I searched a bit further on more general forums and it seems that I found the answer, so I post it here for others facing a similar problem.
It is not impossible but requires quite an experience and expertise to replace the microphone as it is soldered on the pcb. It needs high temparature heating and then the soldering of the new microphone. You can find new OEM microphones on Ebay (there are recently two offers: 3 - 6 USD price range + shipping), but you have to find someone who will replace the mic for you and who is experienced well and will not destroy your board with this procedure.
Here is a simple description of the process:
1. Set heater of your rework station between 400 to 417 degrees celcius, and air make the pointer of the air knob point aj 9 o'clock.
2. Select nozzle size that is not too big or too small for the mic.
3. Apply ample paste on the mic and direct the heat on it. Remove the mic with metal tweezers gently.
4. Apply paste to the interface of the mic to be soldered and then apply tiny solder on the pads to be soldered.
5. Place the mic correctly on the pcb and apply heat from the opposite side of the pcb, and remove the heat when the solder is melted.
Some have reported that this method really works, however I found no information whether it also works for the Excalibur as the interesting point is the exact place of the mic, so by heating it you will not damage other parts of the board.
I contacted the official HTC service and some other mobile experts, so I am looking for someone that can make the replacement for me... It is recommended that you also proceed similarly.
I hope this info will help.
If the mic sometimes works and other times not, why not trying to re-solder the contacts first? This is much easier than removing/replacing the microphone as you can apply the heat one contact after the other.
Dumb question: You are not covering the hole for the mic. with your fingers from time to time?
Thanks for the reply tobbie. I am surely not covering the mic with my finger or any other body parts ; ) So it must be the mic and not me causing the problem. For the time being I am still chasing someone experienced who could do the soldering for me... In the meanwhile I have flashed my ROM from 3VO.2.80.092509 to 3VO.3.50.033010, just to see whether this might be a software porblem. Flashing went well but problem remained. You are right pointing out that the MIC might be absolutely OK, as it sometimes functions well, and this might indicate that the problem is with the connection of the mic with the board and not the mic itself. However if I take the phone into pieces, then I would like to get it done, so I might still order this tiny mic on the internet. Out of curiosity: does anyone knows whether these mics are compatible with each other or not: I saw many Motorola (e.g.: V3) mics that look exactly as the HTC S620 mic, but I don't know whether they are really the identic.
For the time being I use my BT headset till I (hopefully) manage to solve this issue.
For a start, I would stay with HTC devices. All the older ones I have disassembled (typhoon, hurricane, tornado, excalibur, vox) share the same microphone (at least from the looks). Earpiece looks identical for all except the vox, ring-speaker looks identical for the 3 candy-bars while excalibur and vox seem to have the same as well.
Buying spare parts is usually more expensive than getting a used device with a broken screen or otherwise damaged. I have two definitely ruined boards (Tornado with a dead LCD interface + Hurricane with intermittent shut off) and some Typhoon parts that can not make a complete device.
Never soldered anything on the PBA - it is really delicate and if you spoil anything the board is gone. Possibly try to record something with the PBA accessible and apply some force to the mic while doing so. This should reveal if there is problem with soldering.
Many thanks for the help tobbie.
I will give a try and see how the mic would respond for such a "treatment". In the meanwhile I found a funny forum response from a guy who replaced a PCB soldered SonyEricsson W880 mic without a rework station, by just using a gas butane torch:
"I just managed to replace it. It wasn't so difficult.
First you have to unsolder the mic on the PCB (I used Gas Butane Torch from B&Q as I havn't got a Rework Station)
After that I found some old mic laying in my draw from samsung. I soldered it to the PCB using two thick copper wires
ps. If yo damage a track on the PCB you can solder a positive to the capacitor on the other side of the PCB."
Well it sounds a bit weird, anyway I would still go for an experienced expert with a rework station and proper equipment for replacement.
Danke und tschuss
Last night I dissambled my HTC s620 (it was a bit harder then I thought) and got to the mic, which is under a small rubber case, I cleaned a bit the surroundings, checked the contacts, but from the first sight everything seemed to be tight and fixed, still I pressed the mic a bit but no better mic functionality, actually now I can only here everything said in the mic very-very low and from last night there was no occasion when I could record with normal sound level. This might still indicate bad contact. Anyway, I will get now a replacmenet mic on Ebay and try to replace it. Will report whether it has really solved my problem.
The mic has the following numbers on it: S777 261, I don't know whether these types of mics are really compatible (I assume that they are - not only within the HTC brand but also with similar Motorola mics), anyway I will not go for a cheaper V3 mic but buy one which is advertised as an HTC S620 mic.
Same problem.
I've been using my excalibur for 2 weeks and, last night, in the middle of a call, my microphone stopped working. completely. does anybody have any idea of what i can do to solve this problem?!
please, i'm desperate.
