Anyone know how much to replace the motherboard on Bell S3

Hi,
My phone cannot turn on anymore and i got it more than a year from Bell Canada. I went to a place who can repair the phone and found out the motherboard was burn because of some water around the usb port. (Not sure why...because no water go in that i can aware of)
But they cannot fix the motherboard for me and i would like to know anybody know how much samsung will charge for the whole repair?
If expensive, i think i will go to get a new phone instead.
Thank you

[Q] The thin vertical piece on the mainboard that leads to USB connection cracked

Hello to anyone reading this,
This crack in the board happened after it went through the clothes washer, and it was gf's phone so i feel really horrible about it :crying:.
Anyways i have yet to even find out what this piece of the board is named. It's cracked in two places on the vertical part of the board that leads down
to where the usb connector is located (everything else appears looks ok just these two cracked pieces). I'm just looking for any help at all, hoping
someone might be able to offer any help at all, or if it's even possible to salvage. I have an uncle that is got a good amount of experience in
soldering/electrical stuff and can handle the soldering/fixing since im still a bit of a noob, but he was unsure about how to go about it since it would
require some very small wires to fix the connection traces, so if anyone can offer any advice or instruction on mending i would greatly appreciate and
can send some BTC for your help. I attached 2 images, and can supply more if you need more detail.

So far the only thing i can think of is to get a broken board and remove the part i need at the easiest location it could be re-attached... no clue if that easier area exists though..

Why not just bring the phone to some phone repair shop (or a samsung specialized one), if available in your region. They should be able to repair it (if the price is ok with you), or be able to sell you the part you need (order it).
**It looks like even some chip is chopped... at the very least, probably too much water damage on them. You don't want to do this repair by yourself (or you uncle)... there are cases of phone components getting too hot and on fire if there are faulty wires/connectors.
****Definitely a new board is required.

Thanks all

Hi,
Only thing I can think of is that somehow it has damaged the cable from the touchscreen or the tiny wires that feed into the cable without damaging the screen. I came across a brand new screen I was replacing once for someone that had a similar problem where the bottom left hand corner wouldn't respond to touch unless there was firm pressure on the screen to create contact, and this was a brand new screen. It could also be that the touchscreen connector needs to be pushed back onto the board if it's come a bit loose.
If this is the problem, you can fix it by yourself although I'd have a good look around youtube, there are heaps of DIY videos of how to replace screens. If you do go down this path I recommend you replace the touchscreen/LCD/LCD frame in one go, as it's generally already pre- assembled the only thing here is that there are 3 brands of LCD's HTC used with the phone and they aren't all compatible, and you can only tell by pulling down your phone and looking at the LCD flex cable colours, and the other thing is that the screens that are available aren't always the same quality as the original. If this sounds to hard your best bet is to take it somewhere and diagnose the problem just in case it's something else

Wifi and bluetooth stopped working after rain..

Hello,
my S4 mini took a lot of rain under an incredible thunderstorm where i live (Italy).
i dryed it with a ventilator but after 3 days the bluetooth and the wifi stopped working..
also since today the radio stopped working..
i opened it and i found the left upper corner with a lot oxide..but i found oxide also in other parts of the mobile (the mobile was used for an year by one of my friends).
I ask you if this damage could be fix..i thought about a spray for oxide (used also with a toothbrush), or trying to change directly the wifi and bluetooth antennas, changing directly the middle frame of the device..
I am not an expert so i ask you help, please
Thanks in advance.

Severe water damage... Rip
Sorry man I don't think it can be fixed
Its already damaged I would disassembly and clean everything with a contact cleaner and try

If u have warranty u can claim it.
If not you may have to pay for repairs.
But i fear that your device is seriously damaged. Do not attempt to repair it urself. If anything goes wrong it will affect other working parts.

thanks to both mates

For exple in my country the problem is that water damage is not covered by warranty, yours could be different

any chance to find schematics of the pcb?

Hi guys, i have an issue...my phone dropped in water...everything is working fine (i swapped components with another phone) but not the charging part...battery is good...
disassembled the phone, in the pcb under the metallic plate there is a burned component...i have a friend that can replace it but i need the schematics of the motherboard to choose the right component (voltage, power ...)...i can't find online a schematic of the motherboard, can you guys help me ?
the problem is that phone won't charge, it gets power (with tester i can see it) but phone olny turns on for a second and then shutdown...i think the component is a power regulator or something like that
ps. sorry for bad english

Since you dropped it into water it's big chance that much more parts are screewed. I suggest you to disassemble phone and look to motherboard an electric parts are they rusty, rust will be white color if there is a lot of that than you shouldn't fix that part because a lot of stuff is broken or will break soon. You can try placing phone in supersonic bathtub but that won't help for long time in most cases. If your friend can replace part than he should know how to find that part if he have knoweledge in that area.

don't worry, the other parts work good...i swapped all parts (lcd, speaker, touch and more) with another motherboard and everything working fine...after i dropped in the water i cleaned the phone without turning on from everything...the only damaged part is that chip (burned) under the metallic plate...the rest is clean as new and working...if i can identify that chip (o what the hell is it) a friend of mine can replace it

Well, I doubt you will find scheme anywhere online. What you can do is to post picture of that part which is broken/burned and post picture to some forum for electronics maybe someone will recognize it.

Hey, is this (https://goo.gl/qMGcmV) what you're looking for?

i don't have the phone right now, i asked my friend for a picture but still no answer

thank you but no...i'm looking for the schematics of the motherboard...i'm putting a picture of the damaged component
