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

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.

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.
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!

Hi i have looked just about everywhere i can find and have been unable to find any sort of concrete information, if anyone has themselves replaced the digitizer how did you go about doing it? As of now i am unable to tell if it is possible to take the screen off from the front and snake the connector back through where the other one went and just hook it all in that way (it is my understanding that it is held in by double sided tape making this possible) thus avoiding taking it apart piece by piece, or if i will have to take the entire unit apart piece by piece to do the install(also i suppose if anyone knows a few specific screws that will release the whole insides as one unit it would be very helpful). Anyways anyone with any experience doing this your advice would be greatly appreciated and if not i suppose i will be tinkering with it and try to figure it out on my own.

Try youtube. I found one for the eepad tf101 i think http://www.youtube.com/watch?v=k-6dKsGJ4VY&feature=plcp its the best reference you can get...otherwise keep trying repair websites I think Ifixit would be a good place ( although I can't be 100% sure). I dont know for sure but it seems that the lcd and the digitiser are most likely adhered together, most capacitive displays are these days are; so the best option would be to use a heat gun to seperate the two or i guess a hairdryer. But thats after you remove all the frame and stuff off it lololol. So you might just have to spend at LEAST two days with nothing to do besides repair...If it happened to me and if asus voided my warranty or i ran out of warranty I would do it...considering I have experience with repairing laptop lcds and phones, so I guess I would be brave enough to try. Otherwise the cost of repair is 200+...and by comparing replacement digitisers http://www.ebay.com.au/itm/Asus-EeePad-Transformer-TF300-Touch-Screen-Digitizer-Glass-Replacement-Brand-New-/280929374154?pt=LH_DefaultDomain_0&hash=item4168b20fca#ht_4213wt_1397 this being the cheapest, you might have to look at the most viable option here. Hope this helps. Goodluck
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??
Hello,
Unfortunately, I am in possession of a Galaxy S4 I9505 which has been dropped into water. It doesn't show any signs of live except a single vibrate after around 6 seconds of holding down the power button. Drying the device in rice hadn't helped, so I upped the ante and submerged the motherboard of the phone in ethanol as per the instructions of a revive-a-phone kit and left to dry for some time. After this it still didn't work, so I assumed that the motherboard was simply too damaged.
I had managed to buy another used phone (working, but with a smashed digitiser) and swapped over the motherboard from that one onto the new. Unfortunately though, it still doesn't work. I have disconnected all of the connections to the motherboard (the externals that is, camera etc) with the exception of the video cable and it still does the same thing.
Is there anything I am missing? Or does it look like the LCD is at fault? If so, would it be in any way possible to exchange the LCD without replacing the digitizer too?
I am sorry for the drawn out question, but any help would be very much appreciated!

AFAIK, digitizer is connected with LCD by some glue...
However, putting the phone into ethanol itself could potentially kill the phone, as it is a good solvent for any acrylic based paints, isolations etc...

I think the idea of it is that it will dissolve any deposits from the water that might be left on the motherboard. I had used it to some success on another phone, but no luck this time. In any case, it was only the motherboard that was submerged, not the entire phone as the guides would suggest, so that couldn't be the problem.
Agh, I see what you mean. I have gotten time to view some videos and it seems it is neigh on impossible to remove the screen from the digitizer. I bought a second phone with the only piece I needed being broken!
