I had to repair a no speaker fault in one of these. what i found was the rear housing was touching one on the solder points of the hands-free socket, shorting to ground. See the picture for location.
The speaker would work sometimes, but then stop, especially if the unit was put in the cradle (which probably moved the housing slightly to cause the short).
A tiny bit of electrians tape over the solder and problem was fixed
If you have resoldered you handsfree socket you DEFINATELY have to put tape over the solder because the extra solder will make it touch the housing.
Hope it helps some of you. Maybe when sometimes when people jiggle the headset socket to get their speaker working they are really just moving the case slightly and that's what's fixing the problem?? ... or maybe 2 separate faults, not sure. Try the fix and see...
EDIT: cutting away the intruding part of the housing seems to work better than the tape
I've tried this in 2 XDA II's. I put my headphones it one and it works but you cant hear it and you have to hit the cap around a little for it to get sound for a slip second. I put my headphones in another XDA II and it works fine.. So obviously there is something wrong with this XDA II's headphone jack. The rubber cover to the headphone jack is missing, would this have any effect on it?
EDIT-
When I put it in the broken headphone jacked PDA when I insert the headphones in it makes a crinkle noise from me pushing it in. The other XDA II goes in smoothly. =/
Hi.
Rubber cap doesn't change anything (apart from stopping rubbish from getting into connector )
What you described is a case of worn out connector (in PDA).
It happens sometimes. Jack type connector aren't so tough, especially when you plug in and out often.
If you dismantle Blueangel, you'll have clear view of connector body soldered to PDA's mainboard.
You can do it. You can let somebody do it. Or You can leave it to professionals.
The connector needs to be replaced (very cheap part).
Maybe it's enough to bend metal terminals inside a little. A person who does hardware will know.
There's a optimistic version though.
Maybe only cleaning the terminals would do for you (I doubt it though).
It can be done without opening BA.
I'd recommend using some special spray (for cleaning electrical contact metals). Ask in electronic parts shop.
Good luck.
I ment my XDA II, not XDA IIs, lol. I have no expierence with opening the phone but I am good with electronics, but I don't know exactly what I'm looking for =/. I think I might just buy the HT820's Bluetooth headset, that would solve my problem overall.
Faulty socket repair...
Hey guys,
I have the same problem as above (crackling sound through headset) and the O2 service centre said it would cost £97 to fix.
But just did a web search and found a small company in London that said they can fix it (within 2 hours!!!!) for only £30!!!!
Im off to get it sorted so I'll let you know how it all went!!!
Richie Rich.
Mine wasn't like this until I bought it. I bought it from a friend for only $100USD because I'm very good friends with him, it works fine perfectly but the only problem is the headphones don't work in it (any headphones) and he knows there is something wrong with the jack, it wasn't like this until recently it happened. It's cheap to fix probably... but I'd rather just buy the HT820 bluetooth headset, its a good replacement instead of having to send in the PDA to fix a little headphone jack port I wont be ever using sooner or later.
but hey if that place fixes your phone, reply to this topic I want to know!
Headset Jack
I had this exact same problem in the past.
The headset would crack and go out every once in a while, sometimes I would have to move it around in order to get any sound at all.
I didn't do anything about it until it completely broke off, yes the inside plastic connected to the motherboard broke...
So I went to open it up, its not that hard, just a few screws, but I had to buy a torax screw driver (not that expensive)
I was also a bit shy about opening it, but I found this post:
http://forum.xda-developers.com/viewtopic.php?t=8525&highlight=opening+himilaya
you wont have to open it all the way up... just pulling the back cover off, then you will see the headset jack,
If it isn't broken or cracked then your solution would just be to take the metal connectors and a flathead screwdriver, and bend them,
Don’t bend the metal connectors too much so you can’t put a headset in, but just enough where there is definite connection around the headset,
You might want to put a headset in and see the dimensions before you close it (to save you from opening it up again)
You might want to clean the metal if it is dirty, ether with a dab of eyeglass cleaner on a soft cloth (eyeglass cleaner works well with electronics, due to the alcohol that evaporates)
Although if the metal is encrusted or rusty, you might want to take a small strip of sandpaper, or some abrasive object, but don’t rub too hard or you'll take them off!
Don’t worry too much about opening your device up; it is not hard, just open it with caution.
Good luck!
imablackhat, hi, did u mean that ht820 can output sound from media player & every sound from xda2? my current BT is bluetrek G2 and as far as i'm using it for talking only. how many hours the batt can last if we continously hear musics?
its 17 hours of music, www.expansys.com, search HT820, its the headset. I'm considering buying it for cheaper on eBay.
i damaged the internal mic of my magician while trying to change the housing.
so i just removed the mic from the board so that i could solder a new one as there is no service spot around.
the replacement mic i have, has only two terminals but the place from where i removed the mic has 4 (as marked in attached image in red)
and the similar mic is not available.
is there any way i can make the spare mic i have to work on magician.
can somebody guide me where i should solder the two terminals? and put a new life in my old favourite?
thanks a lot.
Microphone Problem
Hi mariner_heart,
I'm new to this forum, I bought an internal mic from ebay, the ebay trader's name is e2shop.
I was wondering how you are going with that as I have to replace my mic when I receive it.
Is their any way you could explain to me how to take the old mic off please would be much appreciated.
Regards,
tassie
hi dood. as in your picture, use a usuall mic and put a 4.7 kohm resistor between 3,4 then wire pin 4 for + of mic and - of mic to pin 3
Hi. I broke my 3.5mm adapter, two of the connections are now broken. I soldered both wires back but I don't know if they should be soldered with a specific contact. I chose the each wire with a contact, randomly. I put the little plastic case together and, of course, it doesn't work. The sound still comes out of the speakers.
So, is it ruined? The adapter is very simple so I thought I could do it myself.
My second question is that if I buy another adapter, would I have to buy one that's stereo? I saw some descriptions on ebay and some are listed as stereo and some as mono, but they look the same.
Thanks.

I did some surgery on my 3-in-1 USB Adapter and repaired it. I'd left my headset plugged into it when I put it in my bag and something must have pressed against it, pushing the socket at an angle and causing the case halves to split apart. I fully dissasembled it and when I realised the studs which the screws go into had broken clean off, it was out with the superglue with a thin bead around the edges and squashing the halves together in a rubber jawed hobby vice while it dried. It's all fixed now but as the halves are now inseperable, I cant tell you which of those thin wires goes where. The obvious choice would be to carefully inspect the blobs of solder to see which have a 'stump' of wire still embedded in them and try those but be careful because Russian roulette with the wires cannot be good for the circuitry in the phone if you get it wrong. There is a picture of the HTC extUSB pinout accessible through the Kaiser wiki and if you have a multimeter, some thin copper wire for probes and lots of patience, you should be able to work it out.

I've not seen a mono one but as the device I have was very cheap (under £10) and plays stereo fine, you may as well splash out on a stereo one
Ok, so.. i have this broken microphone on a hd2 board and need to replace it. But.. the microphone is soldered to the board + a metallic shield over it, also soldered to the board.
I removed the original (broken) mic and the shield and noticed it has 4 contacts to the mothebroard. I don't know if it's a digital mic, or what type of microphone is it. I soldered a couple of wires to that spot and placed an external mic to test to see if the board is fine. It worked, but i had a relatively low gain on the microphone. I tried to solder a nokia mic inside, but failed because i heated the mic too much (microphones and heat.. not good buddies). I cannot fiind a direct compatible mic so i need to improvise something.
Does anyone has an ideea about what types of microphones htc uses on hd2 or similar phones? And how to safely mount it on the board?
hd2 mic replacement
Hi Bogdan. Can you please share your experience with the hd2 mic? I have the sae problem after keeping a hd2 board in isopropilic alcohol after the phone took a bath. it works fine noww but the mic has very low gain and I think it's diafragn was destroyed (or at least the glue) by the alcohol. I would like to change it to some other mic, but after I red what you wrote, that it has 4 connections i'm in doubt. Did yu manage to make a "transplant" and have ot working? Also, I have a problem with the screen orientation (internal gyro sensor ) meaning the screen won't auto rotate after i removed the metallic band from the bottom of the screen, that connects the front to the bottom of the screen of smth like this (GND). Have you seen that problem? Problem is it works normally on Windows mobile but doesn't on android.
Thanks.
