mapping hardware for this device

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.

i suspect you confuse ppl by mentioning BA in your post but writing your post in more then 1 forum not related to BA if BA == blue angel

It seems you have posted this in more than 5 different forums topics.
This will not get you an answer quicker. Please, as this is a BA device, would it be possible to just keep the posts either in the BA topics or in the Upgrading, modifying, unlocking topic.
Please don't feel insulted, it's just that some people use the "view posts since last visit" and saw 8 instances of the same message.
Anyway, to your problem:
1. I guess it is best if you do try first if the bluetooth has sound. If it does, maybe it is the speaker, if not maybe the sounds are set to off for phone sounds. Check the volume slider.
2. Can't help you with the battery problem, sorry

Qtek 9100 - Mic & speaker dead, for the 2nd time

Hello all!
First, thanks for an awesome forum! It has both helped me tweak my Wizard, and also get help when I have needed it.
Well, I have no choice now but to ask here. Last autumn, my warranty was almost up, and a wierd problem presented itself. The mic and speaker suddenly just stopped working! The sidespeakers still work, I think, because the phone rings when someone calls me. But the caller can't hear me, and I can't hear the caller. And there isn't a hint of sound in it, no static or noise, there simply is nothing.
As there were only a few days before the 2 year warranty was up, I ran to my dealer and turned it in. A few weeks later, the phone returned, working again. But now that I come to think about it, I don't remember if I got a replacement or if they actually repaired it... It looked a little like they handled it rough though, maybe it was another phone... Well, that's not important right now.
The same thing has happened again! Summary:
1. Mic & phonespeaker dead
2. Stereo speakers work under certain conditions
3. Wired headset that came with the phone works, both for calling and media
So it seems like a hardware problem. Please note, although I downgraded the phone to original, official Swedish Qtek 9100 ROM, it has been thoroughly tweaked and upgraded to a number of different WM6 ROMs - but all that has been working beatifully!
Still, what are the odds for the mic&speaker dying twice in a row, on different phones (i think the present one is a replacement)?!?
Question: Does anyone recognize this? Is there a possibility that it is software related, and maybe fixable? I have searched both the web and these forums but haven't really found any information on it.
ANY input would be greatly appreciated!
Additional information:
Qtek 9100 (Swedish), G3 model, WM6 upgrade successful (unlocked)
EDIT: There are no system sounds, which is wierd, because the phone can still ring. I thought the system sounds came from the stereo speakers on the sides of the device?

Hello all!
It is a glorious day to be alive!!! Or to have a fully functional Wizard, at least!
Lol - my topic isn't very old, and i reply to it myself with a solution (?). I Googled after the Wizard service manual, and found it right here on Xda .
In all honesty, i didn't do all that much. I just followed the disassembly instructions of the wizard about half-way through, to the point where you get down to the back of the motherboard. I poked and fiddled enough to locate the mic assembly, only to discover that the mic is soldered to the mainboard of the phone. So, i figured i'd just leave it be, because if the mic is really broken the motherboard needs to be repleaced, or a replacement mic needs to be soldered on there.
After removing A LOT of dust in there (honestly, i think the service center that had my device last time wasn't very careful with anything, even a screw was missing! ), i reassembled it. The flat cable running to the keyboard was also a little skewed, but that may have been me, anyway i corrected it too. Same with the speakers.
Long story short, after successfully reassmbling the phone, i fired it up, called my home phone and voila! I works!
Not much of a fix, as i don't really know what i did exactly, but dust, dirt and some bad connections/soldering may have benn the culprit.
All in all, i'm very pleased with my afternoon here. Thanks for stopping by .

hi epatnor,
I think the problem with your phone was a stucked microswitch in the 2,5 mm connector for the headset. I read about it here in the forum. Sometimes the switch stays in the closed position and the phone still thinks the headset is connected. Thats why all the sound is sent to the not connected headset and therefor your phone seems to be not working (unless you connect the headset)...
But removing the dust is for sure not a bad thing...
For the next time: I think there was an easier solution for this problem than disassembling your phone...
regards
huibuh_1

Thanks huibuh_1,
Yes this was probably not the smoothest way of "fixing" it. That said, the stucked microswitch theory would actually fit my problem well - I can see now that the exact problem I was having would arise if such a switch was indeed stuck.
However, I think that the problem would be more intermittent since I actually use that port now and then - especially since it's the only way to talk (besides using a bluetooth headset that is). And since I connect the wired headset now and again the switch is used and moved, I suspect that this would result in the speaker/mic coming online again maybe..? Temporarily at least?
All the same, thanks for replying - this might happen again and with your information I'm better prepared for it!

Tips for buying a used universal

Hello! could people please share tips and things to remember when buying a used universal? I mean what are the things that you should do to check or find tell tale signs of defect, hardware, the firmware the os, I have already done a search in the forums and already know some, but there might be things that I have missed, so help would be very nice, I will be meeting the seller so I get to inspect the device up close so it would be nice to armed with the info how to inspect the device from how to check the bootload etc.
Thanks for the help and I hope that this helps others too

The Universal can be bought cheap at german eBay. Look for MDA PRO. You should be able to purchase one for around or less than 100 Euro.
Preferably look for the following signs:
1) Unmodded. Many users got the Universal within a contract from the operator, but did not use it much, because it is too big for them. Such Universals are normally in good condition. When advertised that it ships with an OS different than WM5, you know that the owner has been flashing it. I personally don't like that, because that means it belonged to a power user and must be more worn out.
2) Warranty stickers. Make sure the hinges have the warranty stickers inside. If they are missing, the device has been opened. You don't want to purchase one that has been opened.
3) Screen. Screen should be without scratches and should have had always a screen protector.
4) Speaker. The external speaker which is used for calls can break, as it is fitted with some kind of pogo pins. Make sure it is working.
If you get to test the device first, do as this:
- do a call (bring your SIM card)
- check WLAN and Bluetooth (bring a headphone and try it somewhere with WLAN activity)
- bring a SD card and see if it is read
- check for bad pixels
- play a song
- take a picture
- try the keyboard and touch screen
- try all the buttons
If everything works, that is the best you can check it for.
Of course it could break the next day, but it shouldn't.
Cheers,
vma

Great guide vma!
I´ll just add:
Take special care on the swivel piece (The one that gives Uni it´s great and unbeatable form factor: PDA - Micro Lap top)

take care of another thing when i bouted my universal after i used it for about 1 week the phone was hangs soo much the reason was in the memory crd .....so you must try a memory crd and play a small video on it about 10 minutes

The most important thing everyone forgot to mention is USB port. When looking for a device, see if the port moves in any way or wiggles in its opening. See if the device synchronises with AS, charges etc.
The fact the device had been flashed or opened wouldn't play a huge part for me if everything else works well and the body is in sound condition, e.g. the hinge is not loose, the screen rotates and closes properly, all keys are present and work, keyboard backlight works with and without sensor etc.
Speakers don't just break, as post No2 claims (POGO PINS??), but it is good to check that phone is capable of making/receiving calls, you can hear the other party and the other party can hear you, can play music and earphone plug is in working condition/attached properly
Not reading SD or SIM card is a biggie, dim screen, lost touch sensitivity, scratched or damaged digitizer, worn out buttons - all obvious signs. You can open the back, remove the battery and SIM card and check for a small white blotting paper sticker covering the small mainboard pins under the SIM card, any change in color towards pink - do not buy.

@enigma1nz:
Shame on me, I did indeed forget the USB port!!! You should of course check both: charging and Active Sync connection. A broken USB connector is a mayor issue and hard to solder without proper equipment.
Regarding the speaker: I am speaking out of experience, as one faild on me. The speaker is like a small button and it has two contact plates. They are not pogo pins, but act like them. The speaker will be pressed by the case against two contact points on the PCB. What happens is that apparently some car-holders do too much pressure on the sides of the Universal casing, causing the speaker contacts to bend back and forth everytime the phone is placed or removed from the holder. After a few months the contact gets worse and worse until one of both plates brake off. Because they are so tiny, it is impossible to repair the speaker - believe me, I have tried. I ended up buying a new speaker cell at eBay.

vma

And believe me, I repair devices for a living. Thanks for the run-through, although I could give you the same. It happened to you, doesn't mean it happens often or it is a fault in design. I could give you a list of design faults in quite a few models of expensive cellphones on the market today, the mentioned speakers are not one of them.

I appreciate, the help people! any more inputs? I am happy that all the previous posts were, about how to inspect the device upfront and some other useful tips what to check other inputs will be highly appreciated

Battery can be also considered. Some are sold with good batery some with dead battery. It is not so expensive, but costs something. In general if battery shows less than 50% and devidce still works (even under load) that is a good sign.
Also as for the touch screen - the best test is to open note taker and try to paint something. The painted line must exactly follow the stylus movement if it jumps somewhere, then the touch sensitive layer is bad. I bouht such UNI on eBay (was described as perfect working order), had to replace the digitizer myself.
I do prefer buying not working UNI's on Ebay with good display. Once I bought not booting one - mtty job fixed that. Other time I bouht one where the display was still off - the flex cable popped out from connector. Etc....

Thanks for all the advice people! now, please welcome me to the HTC universal family, (well actually, I have a Dopod 900 but what the heck all are the same right?) your inputs had been essential, for me to get my new baby without any hitches I hope that nothing manifests after the one week assurance the seller gave me
Special thanks to enigma1nz for all the patience and help provided to me I asked her a lot of questions in the pm's but she answered in full detail
Now I have my own device so I will be flashing away, I hope without any problems. Again my thanks to the community hopefully there are more inputs for others who are thinking of buying their 2nd hand universal via meet ups

Excellent news! Congratulations!!! And welcome to the Uni family, of course. As you can see, we are one friendly bunch, all help and support will always be available. Have fun

Damn, I was hoping to do a very good Marlon Brando Godfather impersonation with 'Welcome to the family'

Phew, My Shift is Back to Life: Thank God !

After frying my Shift motherboard sometimes last year I had given up any hope of ever getting it to work again. ( http://forum.xda-developers.com/showthread.php?t=701950 ). I tried HTC support to have the motherboard repaired or even to be supplied with a new motherboard without any success. Tried any relevant outlet I could think of that could source a motherboard but still nothing came of it.
I tried searching for anyone selling a Shift at the cheap but the few ebay listings I came across showed that the device cost is still very high. I started a link here hoping somebody with a dead Shift could sell it to me for spares but nothing came of it. To make matters worse the thread was moved to Xda Marketplace and it was lost and burried in the market. ( http://forum.xda-developers.com/showthread.php?t=937322&highlight=shift+motherboard )
But as fate would have it the other day I searched the Marketplace and came across a guy who was selling 2 dead Shifts and high capacity Shift accesories and spares including 2 Gb Ram stick, SSD and higher capacity batteries. But I was a bit late to the party! The sale had been on for almost 2 months and most of the valuable items had already been sold. But I was still in luck as the dead Shifts were still available. I bought one of them as the other was a complete shell even though the motherboards had problem as the power switches had detached and gotten lost for the both of them.
Fortunately an electrical engineer friend of mine was able to remove the power switch from my dead Shift and solder it to the purchased motherboard. It was a delicate procedure but I can confirm that all went well and my Shift is now back to life. Infact even with the replacement motherboard my Shift booted with all the data and settings exactly the way it was before roasting the motherboard.
Just thought of sharing my experience with fellow proud Shift owners here.
I would also wish to thank the seller (TopRowGuy) for a very swift and smooth transaction. Thumbs up buddy. ( http://forum.xda-developers.com/showthread.php?t=961663&highlight=shift+clio )

Hi Ed, congratulations for resurrecting your Shift and thank you for posting here the info.
While having the spare Shift and old motherboard at the hand, would you please be so kind to have a look at the circuitry of the socket for external headphones&microphone. My interest is related to the non-working condition of the Shift phone on external headphones&microphone with the custom ROMs.
Therefore could you please check if the socket is simply switching mechanically between internal speakers and external headphones, respectively internal microphone and external microphone (just like in any other audio-tape device) or other circuitry is also involved invalidating the phone function when external devices connected. What else gets disconnected when plugging-in that is influencing the phone? Can the microphone switch be overridden to use only the internal one permanently and let only the headphones be switched?
I'm pretty sure that there are many members here interested in your answers to the above questions. So thank you for contributing to this community!

Thank you Axel.
Ok I will check the switching mechanism for the mic+headphones for the Shift and report back. If relevant I will also take close-up photos with both the the jack plugged in and plugged out. Since I have the extra motherboards boards (both winmo and Vista) I will try severall things. But if i am not wrong the headphone jack is actually attached to the windows mobile motherboard and not the windows vista motherboard....
I will do the necessary and report back. Of course I am also very much interested in finding a solution for the century old problem of non-working external mic phone side..... I will also snoop around the Memory Card Reader and see what gives ......

Thanks Ed!
My idea is that we all might get lucky if the phone would work on external headphones (i.e. have some privacy), but with the internal microphone (you have to speak-up loud anyway).
I expect that, just like in any classical audio set, the switching circuitry on the audio out side gets the signal out of an audio stereo IC, which is led further to the ext phones socket and involves nothing more than the connection wires, socket, loudspeakers and earphones. If so, that means that we are OK on the earphones side. Of course this is an assumption and means that there are no active speakers or anything of the kind linking the audio outputy to any input of the mciroprocessor.
I also looked at 4 contacts 3.15mm coax plug of the HTC earphones and microphone and the contacts for the limitation comes from the microphone circuitry, this can be arranged by disconnecting the internal microphone from the ext socket and leaving it connected all the time.
My guess is that the internal microphone is hardwired directly to the socket and is not going trough the motherboard PCB (printed circuit board), in which case can be desoldered from the socket and resoldered to the audio in signal path (also coming from the socket). With this mod inserting the plug will have no influence any more on the microphone path.
In reality things can be more complicated since the same ext socket is serving both WinMob side and Vista side. I wonder if there is a single audio out IC or just the two processors deliver in paralel to the same load (speakers).
Looking forward to your findings.

Axel,
I had a long and hard look at the mic and audio jack/port and I am afraid there is nothing much to gain from a physical examinations of those items. To start with the audio port is covered with a black plastic on the outside so you cant really see what is going on inside when you insert the jack.
The audio port is connected to the phone mobo and not the Vista mobo. The phone motherboard is not spoilt and hence I would not want to strip things from it as it can come in handy at a future date. The internal mic is also attached to the phone motherboard through a printed cable. Problem is without first booting the Vista Bios the phone side does also not boot. I am trying to see if there is a way I might get the phone side to boot. If I can succeed that way I would then disconnect the mic from the phone motherboard and see whether the wired mic can become active as you have suggested.
But all this I am only doing with the dead Shift because of course I cant touch the recently resurrected Shift. I wonder if there is absolutely any way of being able to boot the winmo side without first pressing the power button (attached to Vista mobo) which is missing from the motherboard that I am playing with??? If that was to be possible I could try various things with the mobile powered on and probably even be able to use the mobile side ad forget about Vista on the cannibalized Shift?
Here are some photos of the audio jack port and the mic connection area. Sorry the images are not great as i took them at night and in low light environment.... These are self-explanatory but the long and short of it as per your inquiry is that it is possible to disconnect the internal mic from the motherboard. As to how the wired mic would behave when the internal mic is disconnected is subject to real tests with a working Shift. As to whether you can solder these around I will leave that to those of us who are more technically oriented.......

Hi Ed
I'd read your post. Also, I have som problem about my Shift
the conditions are:
1. it can not be turn on even vista or snapvue
2. When I switch on the power button, only the green light was on at the bottom of LCD screen.
3. I can hear the fan turn on but nothing happened
4. When I use the charger, the battery can be charged and finished it.
Do you think that the mother board have something wrong?
The HTC care center want me to change the board but it cost a lots.
Regards,
Vincent

If the green light is turning on I think yours is a software problem. What about the mobile side? Does it come on when you press the button for switching between the Snapvue and Vista? Try that with the green light on and then we can try troubleshooting from there.....
In the meantime try press FN+F10 immediately the green light comes on and see what happens.....

Hi Ed, thank you very much for your endeavour. Of course I didn't expect to work in this experiment with the ressurected Shift, but only with the spare one.
What kind of a switch is the power switch, is it a single section switch or with multiple sections, is it a bistable or a tip-switch. I expect that it is a single section tip switch which is connecting 2 contacts on the pcb only for a short while while you press on it. If this is correct you may connect the 2 contacts with a jumper-wire just to start-up the Shift. It is true that the Vista part will start first, but I don't see a big draw back in that.

Here are some photos of the audio jack port and the mic connection area. Sorry the images are not great as i took them at night and in low light environment.... These are self-explanatory but the long and short of it as per your inquiry is that it is possible to disconnect the internal mic from the motherboard. As to how the wired mic would behave when the internal mic is disconnected is subject to real tests with a working Shift. As to whether you can solder these around I will leave that to those of us who are more technically oriented.......

Thanks again for the pictures, maybe some other time you'll have the opportunity to come up with more clear ones.
To get some privacy while using the phone my intention was to switch only the speakers on the headphones, but still using the internal microphone of the Shift. That would require some small modifications to the jack-port.
I didn't get it exactly how many motherboards are there inside the Shift? Are there in 3 pcs, i.e. Vista mb, Winmo mb and phone mb, is that right?

Hi Axel,
The Shift has 2 motherboards - Mobile and Windows Vista. But both are connected where the 2 boards get into contact with each other through connectors on each side. There are no cables/wires involved but just direct connectors between the 2 motherboards where they come into contact with each other.
Apparently most of the connections take place inside the printed circuit boards so you cant tell which connection goes where. But of interest is that both the mic and the audio jack are all connected to the phone motherboard yet they dont work in the mobile side. So either these have been physically disconnected within the circuit board or it could be a software issue. Remember how we could not use GPS or phone functions until the great rom breakthrough by the likes of Thaihugo and Cmonex....? I still believe that the issue of wired mic not being active is a software issue.
But the SD Card is a different story as this is attached to the Vista motherboard. It is very likely that there is no physical connection between the Sd card and the mobile motherboard. Well I might be entirely wrong here as come to think of it there is a solution about accessing SD card from the windows side but Vista has to be on...... Will look for that thread and read some more and see how the connection is established.
By the way I did home-made switch for the dead shift's motherboard. The Shift was able to power up and boot but it appears that the Lcd cable is dead (or perhaps the lcd screen itself is dead but most likely the problem is with the cable). I was able to connect the Shift to the Tv through a Vga cable. But I could not do much with it as the Vista software appears to be corrupt. Further the HDD connection cable too is not in very good shape. I hope to get the Hdd cable to be able to do more tests on this Shift using the Tv as the external monitor.
This other Shift will be the official guinea pig and I am willing to make various tests with it as soon as I get a working Hdd cable and re-install windows. However there is a big limitation to this too because apparently the windows mobile side does not show in the external monitor. In other words even if you switch to the mobile side using the Shift button the external screen does not change and is only active for Vista......
But I can tell the snapvue side is active as I was able to call the sim card number inside the Shift I was using for tests.... My intention is simply to use this Shift with my Tv for internet connection and as a basic pc in the living room. I confirmed that the internet connection to the Vista side is active even without having any access to the windows mobile screen. I made these tests with the Hdd cable from my good Shift for a few minutes and thus did not make extensive tests.
So guys I will get back to you with more tests once I get a working Hdd cable which I may have to import from China (parts4repair.com). I might then end up with 1 Shift and half a Shift......

Hi Ed
I'd read your post. Also, I have som problem about my Shift
the conditions are:
1. it can not be turn on even vista or snapvue
2. When I switch on the power button, only the green light was on at the bottom of LCD screen.
3. I can hear the fan turn on but nothing happened
4. When I use the charger, the battery can be charged and finished it.
Do you think that the mother board have something wrong?
The HTC care center want me to change the board but it cost a lots.
Regards,
Vincent

After playing with my other Shift as described above I believe your problem is not the motherboard since the power light is coming on and the fan is coming on when you power your device. So chances are that your Lcd screen is not getting any signal from your Shift. Yours could be a simple problem with a disconnected Lcd flex cable or problems with the lcd screen or damaged lcd flex cable. Easiest test for you is to get Vga cable and test your Shift using an external computer monitor or tv that supports Vga in cable..... Hope this helps.

Thanks PlayStation, great post, thank you for your endeavour!!! Looking forward for further details.
