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........
Just found a coax on e-bay
Hi I hope anyone who is after this coax cable can read this before the weekend is out, as there is one on e-bay for £40 this is the link.

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.

my phone speaker has stopped working, can only use on speaker phone. Any ideas or know where i can get spare parts.
i really dont see htc getting spacial custom speakers made for their phones it would be too expensive and there really would be no reason to
so if i were you i would
http://forum.xda-developers.com/showthread.php?t=275788
take apart my device
and get the part nr from the speaker or simply remove the speaker
and take it to a electronic store and get one like it
The speaker on my mini s stopped working shortly after using headphones in the headphone socket.
I googled the problem and read somewhere (can't remember where) that a solution might be to "blow" into the earphone socket.
They couldn't be serious, could they??? So I blew, and blow me, it works ok again. Maybe muck gets into the socket. As I say, it worked for me.
Headset connector causing issues with internal speaker..
Before you start pulling apart your unit (and voiding any warranty left), make sure to try a bit of Electrolube contact cleaner into the headset connector (and a few insert / removes of the headphones).. The little metal ground pin seems to deform and lock 'out' sometimes.. causing the PDA to get stuck in 'headset inserted' mode...
Unfortunately the only way to fix this if the connector is bent is often to bend the connector back into place (open the unit).
Good luck!

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 !
http://wiki.xda-developers.com/index.php?pagename=BA_Technical
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!
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.

Hey all,
I just replaced the charging port on my m8 and wanted to let people know it is straight forward. My port got corroded and was shorting out, melting the adapter and not charging the phone. I sent it in hoping for warranty, but the replacement quote was $400! (due to S-off they "had" to replace the entire motherboard). The phone has a separate pcb with the micro usb charge port and headphone input.
example:
http://www.witrigs.com/media/catalo...a71cb48e3d52cb890e76f9e6353/1/0/109063-01.jpg
To remove this board you need to do a few easy things:
1) disconnect the ribbon and remove the insulating tape (to reattach to new part)
2) unsnap the small white power cable
3) loosen the screw on the motherboard near the headphone input. This is clamping down the assembly a bit
tools required:
phillips 00
t5 torx bit
spudger/guitar picks
I would recommend prying the phone out of the frame starting from the bottom. I started from the top and bent the thin strip of aluminum above the sim slot when prying it out.
Also, you can pry the bracket/spring off the top of the old usb port to give the new one a tight fit if your replacement didnt come with it (like mine)
Lastly, just note that power button fell out as soon as I pried the frame apart from the guts. This made it a bit of a pain to reassemble - just be sure to reassemble with the top in first. That will keep the power button in place.
The replacement part cost me $30, so it was definitely worth it! phone now works great.

Hey there. Interesting to know that you replaced it all your self . Did you put everything back perfectly ? I mean the display being aligned properly to the body, the speaker grills being flushed with the body; ? Weird to ask, but did you damage anything while doing it all yourself ? Like the screen scratches, or something else ? Sorry, for asking these... Thanks in advance :good:

I haven't re-glued the speaker covers back on yet so I dont know if they will be perfectly flush or not, although they still look flat so I think it will look good.
The only damage is a slight bend in the frame on the screen side of the sim tray slot. The metal is thin, and I pried against it to get the hardware out of the frame. That is why I recommended to start from the bottom when separating the two. Doing this should allow others to avoid this problem. It is slight, maybe 1/4mm gap where it used to be flush along the side of the screen above the sim tray.
Otherwise everything was smooth. The screen/frame etc are still mint.

Cool, you've done it like a pro then. :good: .Any picture describing the damage would be helpful, if you can provide. Is the display mint ? No scuffs/scratches on it ? But, my speaker grills were damaged onto the edges after the repair was carried out. Does yours show the same sign ? I don't mean the flatness of the grills, but the damage that should be done, while prying out the grills. A picture showing your damage would be helpful to me. I could do the same, if you insist. Thanks ! :good:
Mine is busted. But I cannot find the PCB. The link in the op is dead.
Any ideas?

I actually got one off eBay for $17.21. Works perfectly.
Just wondering....
Sounds like you were able to avoid some steps in the teardown guide, if I recall it was damn near a total disassemble. Do you have a lot of experience with phones? I want to fix mine, but don't need a tedious project right now. If I repair mine I'd like to put a mini USB in place of the micro if possible, I've seen too many damaged micro usb to trust or like them. As for the speaker grills, if you're picky buy replacements, they're cheap.

My HTC M8's main call microphone has stopped working, and through searches on Google it seems that perhaps that this mic (first mic, non-speakerphone mic) is built into the charging port. Is this the case? I cannot find anything that explicitly says this, and I'd love to get the phone back in working condition.

I called HTC, the mic is on the USB port, although you should make sure that it's not a software issue first. There are several threads on the internet easily found through Google which discuss doing a factory reset to resolve this if it turns out to be a software problem.
Thanks for your reply. I did a factory reset when I got the phone but it still doesn't work. Does that mean it's not a software problem and that if I replace the usb it should work?

No, but from what I've studied about it, it should work. Feel free to contact HTC, they actually have a live chat available somewhere on their website. Good luck to you.
Very interesting, I contacted htc and we went through diagnostics together and the rep said that I have to send it in. I asked him if the mic was on the usb assembly and he said that it wasn't and rather it was on the motherboard, and I clarified that we were talking about the primary mic which is located near the usb port. Confusing bec everywhere I saw online said that the mic is on the usb assembly. Go figure!

I asked him if the mic was on the usb assembly and he said that it wasn't and rather it was on the motherboard, and I clarified that we were talking about the primary mic which is located near the usb port. Confusing bec everywhere I saw online said that the mic is on the usb assembly. Go figure!

What did you end up doing? Did you discover if it was on the motherboard or the part with the USB port? I've waited a while to repair mine for other reasons, and I am now prepared to fix it. Any information would be helpful.
Just a few notes on my own experience.
I replaced the screen in my friend's M8 a few months ago. Seemed like everything went ok, except after I got done, the mic didn't work anymore. This is strange because it worked fine before, and all I did was remove/replace the circuit board in the process (yes, the small one at the bottom with the uUSB port). However, the upper rear microphone was still working I believe, because people on the other end of the line could still hear if the phone was put into speakerphone mode. I don't know why it would stop working all of a sudden.... Ran the HTC audio test using *#*#3424*#* to confirm main mic wasn't working and that the aux rear mic was.
Fast forward to this week, with my own M8. The uUSB connector was going bad, and I was having trouble charging, so I figured it was time to replace that circuit board. Ordered a new one and replaced, but when I got it back together, the USB port was fine of course, but my mic wasn't working now, just like my friends! On top of that, the headphone jack didn't work at all. Most likely the "cable inserted" signal wasn't getting back up to the motherboard, but didn't check. So pissed off. Also, the new board I got didn't have the bottom left RF connector/circuitry populated. Thinking from research that it might be for the GPS? I should have tested when the board was in there, but didn't. Fixed a bad solder joint on the original board's uUSB connector, which helped, but still charging is a bit messed up. I'd rather have a working mic and headphone jack and have to play with the cable to get to charge for a while until I get another board (from another supplier, jerks).
Yes, the mic is the small chip on the very left side of the board. It has a hole underneath the chip, going through the board and to the front face to receive the acoustics.
I don't know why the mic not working is so common after an HTC One M8 tear down, as it seems many others are having the same issue. One theory I have is that pulling the circuit board from the motherboard while power is still applied (not unplugging the battery first) might be jacking the microphone somehow. Just a theory, but I'd recommend to be safe that anyone replacing the board should unplug the battery cable before replacing the USB/mic circuit board.
I'd just like to chime in to say that I've read about some people having problems with the mic not working after replacing the USB board. From what I understand, there are two different versions of it, and replacing it with the wrong one can cause that very issue. You should look into it.

Mic broken after USB repair
Old thread but I have the same problem. Replaced USB board and now my mic does not work. However I am pretty certain I did order the correct board (had 2x connectors for my Verizon HTC m8). And my microphone jack work great which others indicate is often broken along with the mic. Anyone have any workarounds?
