Hi all,
As i started servicing all pdas for a couple of monthes (only as a hobby, i fix them for friends and relatives), i came across one BA that gave me some trouble.
i got it to replace its LCD that was broken as it was dropped and thats very simple to replace it, so far so good. now it has two main problems :
1. no sound from speaker (even when in speakerphone mode), but there is sound in the stereo earphones (i plugged to the connector by the sd card slot). - i can only assume that a bluetooth handsfree device it will also work.
2. although the backup battery is fully charged, if i remove the main battery even for a brief second, when turned on, the BA acts as if i made a hard reset.
as for solving the problems :
1. using a digital multimeter, i managed to track the conductivity from the internal speaker through its connector, flat ribbon to the connector which connects to the main pcb - so there is no contact problem from the speaker to the main pcb.
using the help from WIKI, i went to site that has the list of all components and their description - the IC that is responsible for audio amp is a MAXIM's MAX4410 which is a stereo headphone driver. a quick look at its charasteristics and typical configuration and i understood that (assuming this is the IC that drives the internal speaker) the speaker should have one pin which is ground and the other goes to the amplified signal from the IC. neither one of the pins showed it has GND to it. so maybe there is a bad GND line to the connector.
2. regarding the backup battery issue i do not know what makes this problem.
I am sharing this info with you all with two ideas in mind :
1. to resolve my problem and know those devices hardware better.
2. because i am quite a while watching xda-developers and WIKI and i got the feeling that a lot of eforth is given to the software side of all those pdas (which is greate!!! keep going, this work helps lots of people and it shows al thos mega corps they are not the only ones), but the hardware is a bit forgotten and left behind. let me tell you this, there are many VERY simple mini projects i made useing electronics (i am an electronics engineer in my profession) that made my life easy . i am now investigating those instruments hardware as i have several ideas to develope useful accessories to my pda (like an external IR transciver to control IR devices like TV,DVD and to communicate with my laptop, and some other ideas) and i believe we can do the same info sharing as done on software side but on the hardware side.
I will thank any ideas, thoghts or commentsabout this matter. Yol.
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.

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.

You try to check the headset jack may be the cause of it
I bought this phone used and didn't find out until later that the headphone jack plays distorted music.
Here's an example. Everything else with the phone is fine. In this video I taped the headphones to the mics on my laptop.
[edit] crap, i'm a noob and can't post my youtube vid. This is the title of it if you want to hear an example:
Samsung Galaxy Note 2. Distorted audio via headphone jack.
Here's what I've done so far to try and solve it.
1. tried 5 different sets of headphones.
2. made sure they were properly seated in the jack.
3. cleaned out the jack for possible debris.
4. disassembled phone and replaced jack with a new part.
5. disassembled phone and cleaned the motherboard and all connections with Electronic cleaner and a toothbrush.
6. Reset phone
7. tried several different music players.
8. turned off WiFi, BT, put phone in Airplane mode.
9. altered all the sound settings I could find, surround, balance, boost, etc.
The water mark on the battery shows it got wet.
The water mark on the frame and speaker is missing.
The water mark on the motherboard is dry.
Also, I've used the iPhone for the last 5 years, so Android is new to me. BTW, except for this, I love the phone. I have thought this was a hardware problem, but before I give up I'd like to make sure this is not a software issue.
I finally resorted to the Reset, and I'm dealing with that right now. I also ordered a BT adapter so I can re-route everything through that. So I can play music in my truck.
Any advice or idea of where to go now would be welcome.
Thanks,
Kevin
I think the water indicator is your best clue that it's a hardware issue. I dunno how to test to isolate the component so you can try to fix it yourself though.
Out of curiosity, did the seller dispose that it was water damaged?

No, he did not disclose that it was water damaged. He also said that the headphones worked perfectly the last time he used it.
I find it funny that one of the screws was missing and the watermark was missing. Obviously someone had been in there and tried to fix it?
It doesn't matter, because I bought the phone and he's not going to take it back. Caveat Emptor. I didn't buy it at Best Buy, I bought it from some dude on Craigslist. I just got a $23 iKross device that will do both music and phone via a bluetooth adapter. I'm going to give up fighting it.
I thought I was going to be in the clear swapping out the headphone jack for $9. It was kind of fun taking apart the phone and checking out all the parts of it. This was kind of a forbidden activity with my iPhones, so it was interesting.
Thanks for your help, and Happy 4th of July!

Wow, that is quite impressive work....You deserve to have it work after you did all that.
It does sound like a hardware issue, but just out of curiosity, have you tried a different ROM?
Also if you have att, you could possibly do an insurance claim if it comes down to it.
I have the same prob. I took it to the Samsung repair center the guy quickly opened it , cleaned the audio jack... dint work, replaced the audio jack.. didnt work...
He mentioned sometimes connecting the jack to some other output devices like some amplifier or some sound system may have damaged the component/IC/Diode/resister/or whatever is responsible as the place where im am.. they have poor electrical earthing as the electricity standards are very poor and may have short circuited / excess electric current reached the phone and spoilt it
The solution >> Get a new motherboard !!! according to the Samsung engineer..if anyone has found a solution please share ! apart from changing a costly motherboard !

I had the same problem, i tried everything. Wiping, different rom, viper audio drivers...
Then i read in a comment on youtube to tighten the screws (especially the one between the camera en the led). Everything works now!
here another solution I found. I know this is a year old thread but it might help other people
I tried testing the earphone jack while the back housing is removed and while trying to figure out what causing it I found out that the ribbon is losing the connection to motherboard so I added another layer to the top of the ribbon connector to keep it in place and the sound distortion never happened again.

Yeah me too. Thats what I do. So annoying
Hey people, I was wondering if anyone has had the faulty headphones issue. After a few days, my headphones stopped working properly, there was a lot of static and they need to be pushed and held towards the screen to function again. This is going on with 3 pairs so it's a phone fault.Maybe all the tech savvy experts here can chime in and propose something.
Thanks!
I have the exact same issue since yesterday... I already tried to clean the headphone jack with no effect so far.
I will unscrew the device and have a closer look at the headphone jack when I find time. Probably not today.

Sadly it's not the same problem visi0nary describes on his blog. The Mass contact is fine.
I had the phone open for a few minutes and it seems like all contact wrap thight around the plug. I guess the problem is a broken soldered point at the back of the circuit board.
I had no time to remove the board completly and check the back.
Maybe you can ask your repair shop guy what he did to fix it? Thanks.

Hey shadowseed,
I took it to a couple of guys in downtown Athens and none said they wanna take a look at an Elephone. And these were techie Asian guys lol. Let me know if you find anything via pm or through here. Thanks. I'll keep looking myself otherwise I'll buy bluetooth headphones.
the problem with bluetooth headphones is that Elephone set the Bluetooth A2DP Bitpool to 35 (basically means compressed data = better range and quicker transfer rate ) which results in terrible sound quality over Bluetooth audio.
I'm not an audiophile but I can't listen to music over bluetooth in my car like I used to with my previous device, it sounds horrible.
This is a software issue but it can't be fixed with a root app or something like this, it's set in the bluetooth drivers. There is a setting under "Sounds & Notifications" called "Lossless BT-Mode", but it does nothing... or not enough, I'm not sure. The Bitpool needs to be raised to 52 or higher for "lossless" mp3 playback.
I wouldn't have bought this phone if I had known this...
UPDATE: I fixed it. This soldering point broke. I didn't solder it, I put a piece of cardboard under the circuit board which presses against the shell. I did this yesterday in the afternoon and used it multiple times since then, it seems to work great.
Put some solder on every point now. That fixed the problems for me, looked like there was no solder there.
Same on my phone >.< seems that the headphone jack has been horribly designed/built then!
The design is excellent, but there are multiple points with no solder on top, just glued or something. That can obviously not work in the long term.. The fix is very easy if you have a soldering iron, you don't need precision tools.
Hello
I have the same problem. I've bought it a few days ago (it has not one month).
What can I do? This phone is warranted?
Thanks,
Diego

the problem with bluetooth headphones is that Elephone set the Bluetooth A2DP Bitpool to 35 (basically means compressed data = better range and quicker transfer rate ) which results in terrible sound quality over Bluetooth audio.
I'm not an audiophile but I can't listen to music over bluetooth in my car like I used to with my previous device, it sounds horrible.
This is a software issue but it can't be fixed with a root app or something like this, it's set in the bluetooth drivers. There is a setting under "Sounds & Notifications" called "Lossless BT-Mode", but it does nothing... or not enough, I'm not sure. The Bitpool needs to be raised to 52 or higher for "lossless" mp3 playback.
I wouldn't have bought this phone if I had known this...
UPDATE: I fixed it. This soldering point broke. I didn't solder it, I put a piece of cardboard under the circuit board which presses against the shell. I did this yesterday in the afternoon and used it multiple times since then, it seems to work great.

Could you please give us a detailed tutorial on how to open up the elephone?
I've tried it today (got the same problem) and failed on removing the white case from the fingerprint scanner.

I've tried soldering the points today and the connection seems more stable for now.
No more bzzing in idle when using headphones (Teufel Aureol), but the quality still sounds like some bad compressed mp3.
Pushing the plug (display frontfacing) to the back left seems to fix the problem.
I've tried putting cardboard between the 3.5mm port and the casing of the phone but no luck.
When using in-ears (some cheap philips) there is still a semi-loud bzzing in the backgroud and since the cable goes sideways there is no way of getting a stable connction.
Did I do faulty soldering or might I've broken the port with the soldering iron?

Thanks!!!
i'm in the business too, since two days, bought a bt dongle, with eragon rom no bad sound issue, but the asycronious in videos of sound and lips movement is bad, so i have to solder...i need an iron, tomorrow i will try, i hope i will fix it. what about warranty??
thanks for the solutions
I don't care much for warranty on a china phone...
I had the problem that the right in ear speaker didn't work but the left one was okay. But after some time even the left got worse and wasn't usable anymore.
Then I opened the Elephone and soldered the parts of the audio jack (like in the picture above).
It improved the audio quality but it still works only for the left speaker. How do I get both working?

I'm facing the same issue, soldered all the contacts and then only left is working.
Did you solve this?

Unfortunately it is still the same.
Well looks like im sticking to bluetooth headphones, was hoping someone would confirm the soldering would fix it.
