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 have a Wizard since more than a year. Unfortunately my wire stereo hands-free is broken. Unfortunately I can't find a replacement in the country I live in - Bulgaria.
So, please if anyone knows the original electric scheme of the stereo headset, so I can be able to reconstruct an available one. Also, if there is a compatibility with any popular model..... it would be great.
http://web.it.kth.se/~maguire/iPAQ-photos/iPAQ-audio-adapter.html
http://wiki.xda-developers.com/index.php?pagename=Connectors
should be the same for Wizard
Thank you...
I will try...... Have you tried this? Nowhere in the text is said that it would work for the wizard. But still it's worth trying... as nothing will be destroyed.
the hardest part with wraping up a wizard compatible headset is the jack part - i wasn't able to find a neat small jack with four connectors in any local store - all they offer are some cheap plastic plugs that fall appart after few uses. the best replacement for it would be some kind of jack - jack camera cable - four wires, four connectors, solid plug. this cable costs about 1-1,5 Euro and was the best thing for me to use since i had nokia 5510 ;] good luck
Guys,
I bought a cradle from ebay (leeonline) because I cannot get a 4 in 1 adaptor from HTC. I tried using the vga-out (17 inch CRT Monitor), rca video out (our Television Set), Brandless USB hub, Generic/standard USB Keyboard and Generic/standard USB Mouse on it all at the same time. Everything works.
Now, I really no longer bring my laptop to work. My athena is all I need for Word Processing, Spreadsheets etc. There are quirks though. Sometimes, the mouse stops working or the athena hangs. (It may be the amount of programs installed.) Then again, It is still faster to boot than my laptop. The other downside is that even with the cradle plugged to the adaptor, It will still consume energy from the battery of the unit.
What I have done to my athena may not be new to most people but I would like to hear from other people what attachments or modifications they have done to make their athena more useful and powerful. In this way, we can all benefit from these ideas. Thanks!
Thanks!

I used to do that, but the novelty wore off eventually. Now i just bring in a mini notebook. It's easier than carrying loads of bits about and connecting things to monitors (though that option is still there if necessary).
Pretty cool though if you like your gadgets.
Leoni is correct, however he can always leave the other stuff connected to the cradle and use it sorta like a docking station, but you would need a second cradle for the home TV. I'm glad this thread started because I myself was considering getting one for my TV. However, what should I do about the audio coming from my device (will I still be able to connect audio to my AV receiver)? As far as the 4 in 1 cable I would be able to get to the audio jack on the Athena however the down side is that not all USB flash drives would be supported with the 4 in 1 cable. Yetdy can you tell me how you work around getting audio streamed?
I think there are a few ways to stream audio.
#1 S-Video if I'm not mistaken is supposed to stream audio to your TV.
#2 Audio Jack to RCA Audio converters connected directly to the TV or amplifier would also help assumming you are using the 4-in 1 adaptor. Cradle cannot help you out with this option.
#3 Of course there is bluetooth connection which is what I am going to use. Got a bluetooth transmitter and receiver from ebay but is currently busted (bad seller). Another is to get a BT that has a changeable earphone/buds. Change the earphone to an audio jack to RCA Audio jack and follow #2.
Hope this helps.
yes and no

****You are mistaken, S-video is video only (the pins are luminance, chroma, ground and something else I can't remember off the top of my head) ****
#2 Audio Jack to RCA Audio converters connected directly to the TV or amplifier would also help assumming you are using the 4-in 1 adaptor. Cradle cannot help you out with this option.
****if it is anything like the one I got from ebay then no, as it covers up the headphones out port from the athena but does not replicate it on the back ! the athena also carries audio out from the same USB connector that you charge it from (this is why the socket on the athena is an unusual/different shape compared to your plug on USB charger) if they had replicated this port propely on the dock then you could have got audio out that way, but the dock connector for that is also wrong (standard USB shaped socket, not the odd one from the athena) ****
#3 Of course there is bluetooth connection which is what I am going to use. Got a bluetooth transmitter and receiver from ebay but is currently busted (bad seller). Another is to get a BT that has a changeable earphone/buds. Change the earphone to an audio jack to RCA Audio jack and follow #2.
****it is feasible to have the athena transmit stereo bluetooth to a nearby device !****
Hope this helps.

just my 2 pence worth
If you want to play audio on your home theatre speaker, you could also consider the option of plugging an FM transmitterinto the headphone jack, then use your FM receiver to play through your theatre speaker.
That was how I used to play my music in the car, through the car's srereo speakers.

wont work if the Athena is in the ebay dock/cradle, as it covers up the audio out port, but does not replicate it.
Ice coffee,
Maybe you can share some other options here. You may have other ideas that may be useful to us. I just got my athena last month and cradle last week so I cannot really say with authority what it can and what it cannot do. If you can help us out in maximizing the athena with its cradle, many will appreciate it.
None of the video outputs from the 4-in-1 carry audio, the only options are BT a2dp or the headphones jack. Seems a bit long-winded to me though - I'm sure there are less fiddly mods out there. I just used to use the magnetic keyboard as a stand, slipped a BT keyboard over the top of it and the 4-in-1 for usb hub etc. This left a free audio jack to use as I wished. Seems like the docking station is more of a hindrance than a help.
HTC Advantage
Docking station
Keyboard
Mouse
Hifi Bluetooth A2DP adaptor
USB Hub....
I think my EEE pc is a more convenient device on the whole than the above setup would've been if i'd carried all that with me I wouldn't have had any space to fit my work stuff!
I came accross another docking station for $119.00 USD that has the audio option on the side along with 2 standard USB ports instead of 1. I think it's a bit too pricey, due to the fact that on flebay they do have a2dp stereo bluetooth adapters for like $50 USD. Besides with that and your bluetooth headsets it might still be possible to answer a incoming phone call on your bt headset without having to hear the audio coming from your A/V receiver (considering you left the phone on). Leoni, both options have their own drawback (no powering source with the 4 in 1 cable for all USB storage devices and the inaccessable headphone jack when using the docking station). But anyway I'm going to order the 4 in 1 cable too and see which one works best for me on a day to day use.
as I said the only simple option is to use bluetooth and as tootalk2000 pointed out you can get adaptors on ebay for £25 ish, I suppose the other more complicated option would be to, take your cradle apart and replace the USB connector into the phone with this,
http://cgi.ebay.co.uk/2in1-Audio-US...oryZ3728QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
and then take the other end of this apart and make it fit in your cradle, it would actually be quite easy to do as there is a lot of space in the cradle.

Awwwww shux, someone just gave me some experimenting to go do. I'm ordering one of those jacks today, and hopefully it will come around the same time as cradle. I'll just super glue it to the back portion of the cradle and plug it in externally. Due to the fact that the USB port is still on there you would still be able to sync even when the ear phone jack is still in use.

lol my thoughts exactly.
Hi all,
to my great frustration, I've discovered that my SGS2 line-out / headphones jack seems to have a slack joint, i.e. if you turn a connected plug around its long axis, a crackling sound is heared in the speakers and at some angular positions the stereo signal will be reduced to mono (i.e. one speaker gos silent). With one device (mobile outdoor speaker) I even had no sound at all at when inserting the plug with the wrong "orientation".
Did anybody experience the same problem or am I just out of luck here?
I am wondering whether sending back the device to the retailer (Amazon) or directly to Samsung (I'm situated in Germany) will yield the faster round-trip time, any experiences here?
Thanks!
PS: I know this may be a stupid question but can somebody PLEASE tell me how to search for multiple keywords with AND logic in this forum? Tried "+word +word" and "word AND word" (without the quotes) but nothing seems to work.
Are you using the headphones that came with it? My better half went through 4 sets of the stock samsung headphones with her original Galaxy S and all produced the same issue of losing one channel after a matter of days/weeks. having the jack inserted to about 2/3rds is a workaround but not ideal as you still lose some frequencies and it's insecure... They're just a bit pony.
No, I used different kind of headphones, including Sennheiser in-ear headphones and a standard male-male audio jack connected to some bigger hifi system. With some jacks I did not encounter the problem, but most of them lost some part of the signal with some orientations: I persume that the manufacturing tolerance of the jacks also plays a role...
Anyway, it's definitely not a problem of the jacks but of the device since I tried it with the SGS2 of a friend yesterday and it worked with the same jack that made problems with my device.
I will proceed sending my phone to Samsung for repair, I hope that won't take to long *sad looking*, I am so used to it now, it's card to survive to weeks without it.
I had the same problem, all I had to do was insert headphones cable "HARDER" into the audio jack until I herd a "click" sound.
I was way to over protective of this phone when i first had it, and wanted to handle too much with care, forced the dam cable in, and "click", sounded like it snapped into place, the audio worked correctly without cracking noise or without the need to wiggle to cable get clearer sound.
Perhaps your friends SGS2 is already used to headphone being inserted, but yours not. Just add a little pressure until you hear clip into place.
If this doesnt help, then repair or return.
Thanks for the hint, but unfortunately I had the jack inserted to the very end, so this was not the problem... sent in for repair now, let's see what happens.
I have a fix for you i think!!!!!!!!
ok . when i got my s2 like 4 days ago (at&t usa version) i noticed that when i plugged into my aux cable in my car that it was low sound cracking more volume on the left side , very annoying . NOW FOR A SIMPLE FIX FOR SOME TO TRY! PLUG IT IN ALL THE WAY! i noticed when plugging it in i wasnt fully plugging it in . it should go all the way down FULLY! the sound is perfect once this is done . I HOPE THIS HELPS YOU !!!!!! good luck
