Hi at all. I'm a Italian iMate K-jam Owner, from this day, and with the splendid help provided by theese topics:
Wizard Windows Mobile 6 for newbies
IWT - Mameli 2.0 Beta - WM6.1 build 20273 - ITALY DOES AGAIN...
i'm happy to test the windows mobile 6.1. It's great, too much great respect the original rom
SO: My pda have a not working flash camera.
For me is much important! I use continuously this as a torch!
But now it doesn't light up...
I've umounted the pda, and all appears correct.
There are 2 possibility:
Flash led broken
Motherboard broken
I would to ask you if anyone try to change this.
I'm able to repair it if I'll know the model (or only voltage and wattage!!) of the SMD led that is mounted... There are no risks to change this because it's on a separated circuit board..
I can be try to use a normal plcc smd white led, but if it has incorrect values it can damage the eintire pda!
Otherwise, tou know about the costs or how to find original led to replace?
Very thanks at all.
Noboday knows?
Working with computers and electronics I doubt that you will find the specific LED that is used as a flash on your phone. Even if you did find the part, would have to un-solder then solder the new part onto your phone. If you are not a professional solder I do recommend messing with the circuit boadrs on your phone. You do sound confident about soldering.
I have been looking for parts for my phone and found eBay.com to be a good resource.
Try buying a used phone and salvaging the parts to fix your phone.
Good Luck

Thank you.
Unfortunately, my problem is to FIND the led. I can use a "simple" led, but this category of leds are rare, and various.
I would the model of led! Or current exact values...
There are no problems with soldering, i'm able to solder, and to sold smd leds, I did practice with a lot of this led on my car indicators...

Also they're mounted on a separated printed circuit board, a small piece that contains also the led and two contacts.
My problem isn't to mount the led... Is to find it.

Sadly, my HTC Wizard/Cingular 8125 USB connector broke off. I'm not sure how it happened but I can only guess the pressure of inserting the mini USB cable wore it's soldered mount points and gave way. I tried soldering it back but when I adjusted those little prongs underneath so it would have good contact with the board, a prong broke off. So I'm out of luck and can't recharge the battery. Does anyone know where I can purchase the identical piece so I can solder it back to the board? Also, has anyone else had this same unfortunate fate?

thanks Calouro, I'll give that link a shot.
wow, i had that happen to me too, i send it back to t-mobile for repair. but i afraid of it happening again, bc it hard to fix and my warranty expired.
These people do USB port replacements I believe:
http://www.pocketpctechs.com/
Thanks Paul.. checking them out.
I just had the same thing happen...PPC Techs as mentioned above does that repair for $60 + shipping. They mention this issue specifically as a K-Jam fix on their web site.
I sent mine in but they advised they were unable to get ActiveSync working again after trying a number the repair a number of times. They shipped back to me via ground FedEx even though I requested 2-day so I don't have it back yet to test...

They may have induced heat damage to the USB I/O circuit. This can happen if the soldering iron is too hot or left on the contact too long. In addition, if multiple repairs where attempted with not enough cool down time between heating, the USB I/O may have been damaged.
Also, if they did a sloppy job and shorted two of the contacts together on the USB plug with solder by not completely cleaning out the old solder can cause issues.
I have a working TMOUS HD2 motherboard which have a "broken/ripped off" lcd connector.
I also have a non working/bricked TMOUS HD2 motherboard complete and without any physical problem.
Is there any possibility to replace this connector?

Any help would be much appreciated.
Is the part here?

I highly doubt it. That connector is more than likely surface mounted with little tiny pins soldered to the other side of the board, and would be amazingly difficult to remove and replace correctly by hand.
That's what I thought...
But it seems that I don't have nothing to lose...
I even have a third broken motherboard (also with a ripped lcd connector) where I can test the "removal" an "relocation" of the component. I know it's difficult, but there is too much to win and almost nothing to lose.
Any tech approach would be appreciated.
I tried to remove it with a heat gun.
It was VERY EASY and the removal was perfect!
Next I removed a good lcd connector from another phone (also without a problem) and that's where the problems began.
Soldering with a heat gun, which is not designed for precision work is like killing a bug with a bazooka... you will kill the bug but you will break something else...
End of story... ended with 2 non working motherboards and learned that I need a reworking station for this kind of work.
its easy I done them so many times without fail

Sorry but can you assist some of us with the same problem in few short tips before I destroy my motherboard too
I might be wrong but is it just the clip that is broken? Do the contacts still connect? It might be possible to glue a thin strip of metal to the plastic ends of the motherboard's connector to hold the ribbon cable connector in place. Might work
I'm installing an HTC flyer in my car permanently where the radio would go (2DIN mounting), but kind of sad at the prospect of losing camera functions (video of dashboard interiors are boring).
So, what would be involved in removing the camera module and placing it somewhere else, as the dash for example? Would I just need to unsolder the camera module, solder on a whole bunch of cables, and connect them to the same contacts? Or am I barking up the wrong tree?
Alternatively, if a device has USB OTG capabilities, is there any way to make it talk to a regular USB webcam?
Discuss
Alot of research could go into what you're trying to do.......
However, I'd recommend just trying it and see what happens. Make sure your wires are all the same length.
So yeah.. In this situation, i think the Leroy Jenkins approach is appropriate.

PRICELESS!! lmao. @OP, awesome idea for the in dash flyer. Please post some completed pics!
have you thought about removing the camera from the back ad making "jumper cables" to put it up front? you might need something to make a housing for it to sit in the dash, but it would be better than writing a driver for it.

The thing is in adding(soldering?) 2 proper connectors to longer flex IMO, hard to do at home, but nothing is impossible. ^^
About OTG connecting - you'd probably use universal WebCam drivers from Ubuntu for eg. though the problem would be in powering that I think, WebCam has to be OTG compliant (with external power connector maybe?) or you'd need some special adapter, the rest is redirecting Android to use your webcam, but don't think it's hard comparing to other things.
I did this with a fascinate in my 87 BMW 325ic
I bought 2 extra cameras ( paid $16ea somewhere, cant remember off hand)
I failed at getting it to work myself as I suck at soldering.
However-
I had a friend take it into work and solder it in for me. We then took a light sensor from a 4th gen camaro , mounted it on my dash, ran the cam there, installed the phone and f-in-a . it was sweet.
this lasted for a full 3 weeks until something came undone and now the cam doesnt work. Ive switched back to the stock deck and just wired a bluetooth receiver into the tape deck, mounted a droid x down by the ashtray and it works. Not as great as what I had, but it works.
Point being, it can be done. and its pretty sweet when done right.
grab fried boards from ebay and start from there.
Wait some more weeks, cotula is developing usb host mode driver, and he has developed a working driver. Its for android. It will be available soon to public when he corrects the errors.
So u can simply plug in an usb cam to ur phone( providing only external power supplay is needed.) So u can do it with out bricking ur phone. Till then use it as a phone..

Hi,
My Nexus 7 Gen 2 usb stopped charging (it was on/off for a while but now fully stopped).
I ordered a new USB component from eBay so I was desoldering the old one this morning but unfortunatley the 5 pins at the back ripped a few of the pads from the board off.
I was wondering before I order a new USB PCB for £40 is it possible to re trace the 5 pins and wire them to somewhere different on the board??
Looking at this picture this is what I thought I could do:

You could try soldering to those solder pads right before the resistors/caps in the path. If you bypass those, and solder directly to the exposed pads you identified, you may have issues, i.e. those resistors/caps are probably there for a reason . That's what I would try anyways.
did you ever end up soldering to these pads? cause any issues?

nevermind, didnt work of course. Ended up soldering to the pads just before those caps, just needed to not be lazy about it.
I'm wondering if anyone can identify the two components circled in red in the lower right corner of this image?

I recently replaced the screen on my Nexus 6P, but these two component came loose (likely from when I took off the screen connector below them). One of them was lost as well.
After replacing the screen everything seems to work ok except that the Sim card is not detected. (The same sim works in other phones.) I'm suspecting that these two components are the issue. It's pretty likely that I would not be able to successfully replace them, but then again it might be worth trying.
Any thoughts? Thanks!
Your image link don't work..
But btw, why did you replace it? Broken?
I hear it's a very difficult and risky process to replace screens on 6P..

I just updated the image in the original post. I think it should show up now.
I dropped the phone from about two feet up and the touch screen quit working. Replacing the screen was a bit daunting, but actually seemed to go quite well until I figured out the sim was not recognized any more. It was a bit tough to pry off the camera shield on the back and to pry the insides from the body the first time. But now I can do it without too much trouble.
I think that the two parts I wan to identify might have been a bit damaged before (water damage?), and then I might have inadvertently helped them along.

I can't see your image for some reason either on Tapatalk but I can in web view. Check ifixit for a full outlook of internal parts:

Edit: On second thought, the piece you're asking about wouldn't be discussed by them.

That's gonna be tough with no markings on the board or components. Google "identify smd components" might yield some helpful results. I think they are either smd resistors or fuses. As a last resort bridge the connections individually with solder or conductive glue. Check with multimeter after you bridge them to insure no resistance (good connection). Really looks more like those are components for the display circuit though.
normally those are some resistor smd.
you can check on other phones (service manuals) what kind of component is there.
i saw a service manual for lg g3 here on xda, you can check whatever you want but try to search for a component like that.
