Power button flex cable replacement - Galaxy S II General

So my idiot brother tried taking apart his GSII the other night when drunk and slipped with a screw driver and busted the flex cable that connects the power button to the man board.
So I found a place in Germany that sells the cable, I ordered one and it has arrived.
The problem is that for the life of me I cannot figure out how to attach the new one, it's not a plug in part, but I think it's supposed to be soldered, or something, but the size of the soldering needed is beyond miniature!! I would need an iron being operated by Lilliputians!
Is there a way that this cable is supposed to be attached? I am at a loss of how it's supposed to be done. Samsung want $450 for a whole new PCBoard... screw that for a joke though!!
If I can't repair this myself I will just sell it for parts...
Here is a link to the "exploded view" of the phone... the part I am trying to replace is QVK02

PS Yeah my brother ordered another GSII when he was drunk and gave me this one... He should probably drink less!!

no clues anyone??

Do you have some sort of a picture of it? Picture of part, the busted part and the PCB where it belongs would be very helpful figuring this one out..
Maybe you can borrow your brothers new GS2 to take a picture of it with!

I beleive it's soldered to the main board.
I can double check to night when i come home, i have a main board that i can look at.
You probably could take help from a electronic repair shop that are used to solder small things.

Thanks for the help, a mate soldered it for me! As you can see the phone works, very excited to get a galaxy s2 for fifteen dollars!

I want your broken wizard!

Please, its been about a month since the earpiece on my wizard died and i can't find the part anywhere! I found one damaged wizard on ebay which sold for $400 with a damaged screen! obviously a fradulent buyer but the seller hasn't replied yet.
So if your wizard is water damaged, smashed, or simply inoperable i need this one part to fix my earpiece. Also my brothers wizard's speakers are blown so it'd be great if i could get a hold of those two.
What i need is the ribbon cable which connected the main board to the top sliding half of the device. Its a ribbon cable attached to a circuit board on both ends.
Please i really need this so i can bring the phone part of my wizard back to life.
PM me if you know where i can get this part or if you have a damaged wizard.
Thanks in advance!
broken wizard!
i do have a working one with cracked screen. where are you located?
i should have mentioned that.. I'm in austin, texas. If u are over seas i can check to see if i can make it elligible for a corporate rate to ship it to me.
Also how much would u be wanted for it?
I'd offer you mine, but I got the same thing broken.
i just emailed 2 sellers on ebay which have cellphone parts and wizard housings in there stores, awaiting there reply. And i'm working something out with the one person with a damaged one from ebay.
What do you guys think $85 good for a wizard with a damaged screen?
broken wizard
I have a broken wizard--I dropped it, but I can still make calls from it via the bluetooth headset.
PM me if you are interested and I'll give you my phone #.
I've pm'd u, but does that mean your earpiece is broken as well? Cuz what i need is the ribbon cable that powers the earpiece, LCD, digitizer, softkeys, and everything else on the front half of the device. So if yours is broken then probably won't help mine out much.
i guess so. If you need an intact (front) then mine won't help--due to the fact that the "cal answer/hangup " buttons do not work.
The damaged one i bought off ebay came in today, swapped the parts out and now my earpiece is working again!! i'm so excited!!
Now i have all these parts lying around if anyone needs anything send them my way. The parts i got are:
The main board
Camera
Vibrator
Main housing (except for the front its really banged up)
Antenna
Keyboard
But no battery cover, didn't come with one.
Heres a pic of the mess i had on my desk but it all worked out perfectly
--------------------------------------------------------------------------------------------
I no longer have the damaged wizard so please don't PM asking for parts.
hey fone_fanatic, wondering if you ever experienced your Wizard creaking when you press down on the front faceplate(below the call/end buttons)....seems to come from the hinge right under the the right soft key (the one connected to the keyboard), only thing is it only makes noise when the keyboard is closed and my keyboard is not loose at all(nice and snug)....just wanted to know if you might know of a fix for my problem, would you recommend me taking it apart or just sending it in for a warranty repair or do you know if it is pretty easy to somehow shorten the gap between the front face and the keyboard?.... appreciate the time.
Regards,
P.S. My Wizard works fine, its just starting to get very annoying when I make/end phone calls.
no, mine doesn't make any noise when i press down there. well there is a noise but its coming from the battery cover. if your device is under warranty, i suggest sending it in if it bothers you that much. the reason being because when u open it up your bound to break a couple of clips which might make it worse.
fone_fanatic: I love that mess on your desk
You might want to mask out your First National Card though - edge detection filters would love that image...

don't worry about the card, its one of those advertisement cards you get in the mail syaing your pre-approved or whatever. i always keep those cards and use them with taking devices apart.

anyone got a 8125 with a cracked LCD but all other functions still working?
yes, i'm aware of pocket pc techs but they didn't have the part i needed to fix mine whihc is why i bought a damaged one and salvaged the part i needed out of it. Now i've got all these extra parts , but what to do with them...?
@ fone_fanatic
thanks for the advice....off to warranty it goes...hope it comes back with no new problems (fingers tightly crossed)....
Regards,
hey can I see that pic of the parts u got left?
I wouldnt mind buying a wizard with just a broken LCD if it was cheap. $180 to send it in to fix a LCD is super expensive when the phone is like $350 on ebay

The reason i bought it the this one with the damaged lcd is because i couldn't find the part i needed (Rigid Flex Board) anywhere so i swapped my broken one out with this one. So if i was to put this back together not only would the lcd be busted but the earpiece won't work also the speakers would be blown (sold good speakers to a friend). Also the front case is heavily scratched/dinged, looks like someone smashed a brick on the phone.

main board

Whilst replacing the screen on my m700 i managed to utterly nadge the main board by breaking off the clip that holds the screen ribbon in place. To make matters worse I completely fubarred the socket by pushing the ribbon in and bending all the pins over. Not only that I then managed to get the battery in backwards and fried a power component. So in short totally assed the main board up. Does anyone knoe how I can get hold of a replacement main board or the longest shot on the planet a place that could repair the stupid damage I have done?

I've seen a lot of parts for the Trinity online, but never a motherboard. I think you may have to send it in for service.

Anyone know where I can send this phone in either the UK or the Netherlands to be repaired?
Try to find ot from HTC's European web site....they must have a number or a telephone somwhere....now If you have messed around with the mainboard, to replace it, outside the guarantee it might be a costly process...maybe you will be better off with buying a second hand one and use yours for spare parts, when and if needed....better ask them for the cost before you send it

Problem on my N1 (de soldered SMD component)

Hi,
I disassembled my N1 for changing the main flex cable (cutted power button) and in the disassembling procedure I noticed that one of the SMD components on the motherboard was de-soldered or not correctly soldered (twisted). I re-accommodated with a pair of tweezers and it did not hang loose (yet!).
What kind of function does this SMD do? Can I expect the phone to work?
I have experience with soldering iron but think this is too small for me.
I can't test it right now because my new main flex has not arrived yet.
Maybe you can solder it with an oven for CMS ?

I'm not very familiar with oven soldering; dunno if I will kill other components or If i need some kind of flux.
Also a heat gun would do the work but probably desolder other components.
I broke off a couple of the smd components right next to that connector (the screen connection) they effect color on the screen. Mine showed only red after I broke 2. It was usable but not pretty.

Thanks for your answer.
You broke those very same components?
As soon as I get my main flex i will try it and see if it report problems. It probably will as that component is there for something.
You might be able to re-flow it with a heat gun.

Actually I'm looking for a chinese reflow station with a hot air gun with a tiny nozzle. Probably will do the work but...
Should I use some kind of flux? Any recommendations? Never done a hot air reflow.
Looks like the same but hard to tell in the pics. I can't really see on my phone.
Sent from my HTC Desire using Tapatalk
that is a set of inline resistors, meaning it is quite a few connections, the best way is to use some flux from a needle and a soldering iron with a small tip,you could use a hot air machine but on a fully assembled board i would not recommend it.. flux is needed but you may be able to get away with a large soldering iron.
My advice would be to pay someone to fix it.. that way if they mess up ya get a new phone
Find someone with a reflow air knife, anyone who does SMT work would have one. It'd take 5 seconds to put that RP back on as long as you didn't break any of the pads doing whatever it is that you did that caused you to break it. Yikes.
May i ask you where u got the power cable? I need one too, how much was it? And is it hard to replace?
N1
I bought it on www.aliexpress.com
It was around USD$45.
I still don't receive it, as soon as I recive it I will report if the phone works and if it is an easy repair.
Best Regards.
The phone it's not turning on.
I tried it disassembled with the new main flex cable, motherboard and only lcd conencted.
Nothing happened when I press the power button.
The only sign of life is the ambar led that turns on when you connect the charger.
The tiny little SMD part fell off the mother board so it is completly unsoldered. Could this be the cause of not turning at all?
Looking forward to your answers.
Yes, if a single component is missing or even has a bridge in the solder, it could cause complete failure. There is a reason for it being there. If it were me, I would try to resolder it. Grab an iron and some wick and get what you can off of the board. Then try to reflow the part back on. If it works, great. If not, you still have a nice looking paperweight.
Well, I soldered the little SMD back with a soldering/hot air station but the motherboard still don't turn on.
It was working before, maybe I'm doing something wrong.
Thanks for your support.

[Q] Scratch removal

Hi,
after my wife dropped my phone (accidently she swears) I have some small scratches on the phone. (See Picture below)
Someone knows some ACME Cleaner&Scratch remover for that?
Greetings .. seems that I have had the HD2 for the longest time ...
OOO!! Ouch! Looks like it's time to see the phone doctor. Or, if you feel brave enough, you can fix it yourself. They have replacement screens on ebay. Since you have the EU model the contacts for the screen and the digitizer are soldered together. So you have 3 options. 1. Take it to someone else to fix it. 2. Attempt to order just the digitizer and if you have some time and surgical skills solder the contacts yourself or, 3. Get a fully assembled LCD and digitizer that is already soldered together and swap them out. The cheapest would be to just get the digitizer but if you have to factor in the time and headache of soldering those tiny contacts together, I think getting the assembled parts would be my choice. The US T-Mobile model has a small plug-in type connector on it so there is not soldering. I replaced mine and it is quite a chore. You have to be very careful and don't rush it or you will break things. Good luck!
Yeah you've got more than scratches there! You've got a smashed screen
You'll have to replace the glass
the guy above stated pretty much everything you need to know but here's a link to a lcd+digitizer combo that is fairly cheap: http://www.ebay.com/itm/New-LCD-Dis...192999?pt=PDA_Accessories&hash=item45fdf14d27
I know guys, the scratches where just kidding
The complete replacement has been ordered already, will fix it by myself

That's great. Like I said be very careful in taking it apart. Especially the flex cable that controls the volume rocker. Take your time and you can get it fixed.
Check out this website: http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
It has some videos on disassembling and assembling the HD2 just so you see what you have to deal with. Also another good investment would be to see if you can get some double sided tape to stick the back of the LCD to main frame if you can't salvage the stuff that's there already. It can't be too thick though because you'll run into problems of getting it put back together. They have that on ebay also.
yes
option one.... change screen..
option 2...change wife.....

PDMI USB connector

hi guys - i foolishly lent my streak to my sister for a while as she had broken her iphone and after a couple of weeks she called me up to say that it wasn't charging and was dead. I figured she'd just done something daft and it would be an easy fix but i got it back today and she's managed to pretty much destroy the pdmi connector (as well as break the rear door catch!) . Phone still works fine as i charged up the battery on the dock and fired it up.
So, is it possible to change the connector or is it soldered to the motherboard? If it's soldered i'm guessing it's a pretty specialist job to get it replaced? Or alternatively, is anybody interested in it for spares? It's in perfect condition as it's always had an invisible shield on it (just removed as it was getting a bit scabby) apart from the connector and rear panel catch....if there is any interest i can pop a thread on the marketplace.
Cheers
Niall
It's soldered. There may be companies which can replace the connector, but I'm not aware of them. You may want to look into replacing the motherboard by purchasing a Streak with a broken screen.
aye, that's what i thought...i've ordered up a connector as it looks like it's the plastic bit that disappeared so maybe be able to refit that from a new one? If not i'll maybe see if a phone repair shop will solder the new one on. Or has anybody got a smashed streak lookin for a new home??
