Hello.
I am in need of board-level repair for my XT926. The connector that the FFC ribbon cable from the LCD screen plugs into was damaged and is missing pins. It will probably need to be replaced.
I have called and searched and can find no repair company that will fix it. Even Motorola (as they will just send me a replacement).
I am worried about the data/pictures I have stored on the phone, so I would like to get this up and running.
Does anybody know of a shop that can do this? I know it isn't a "common" repair, but am willing to pay for it being done to save my data.
Thanks in advance...

I'm still looking for this, if anybody has the skills or no where I can get this done. Money talks.
Thanks.

It would require serious equipment (hot air soldering station with proper nozzles) and a new part, probably from another motherboard. It's by no means an easy fix.
But why don't you try this:
If the phone boots up, hook it up to a TV or monitor with a HDMI cable.
You should see your phone screen on the TV once it booted.
Connect a mouse with a USB OTG cable to the phone.
You can now either enable bluetooth, connect a bluetooth mouse, so you can free up the microUSB for connecting the phone to the PC to save all your data/pictures/etc.
Or you can leave the mouse connected through the USB and insert a microSD card into the phone to save your data there.

My Xda/Qtek's charging slot is loose or bent and as such I am now not able to charge it or synchronise at all. Brought to the repair shop and was told that I need to change the whole mother board as the slot is attached
to the board and it is as good as getting another one than to fix it. Seems to me that the 2 pins in the centre or the slot is bent and I cannot get the connection on when I plug the charger in unless I twist the charger to one side I then get the yellow/orange light which indicate charging.
Appreciate if someone could help fix it. Cheers.
The charging socket is part of the mainboard, I have had this in the past with ipaqs, I got a jewellers eyepiece and a very slim pin and managed to get them lined up again, I am sure there was a post today about this very problem.
Thanks for info. I managed to strip apaart the xda and then soldered the
loose charging slot. It works fine now and I save having to pay for the replacement of the main board which is not worth it and also the service
costs.
help for newbie pls?
Hi, I currently have the same problem. I also want to try the solution that cruisin-thu suggested, unfortunately, I'm not much of a techie and I'm afraid that I might damage the mainboard if I don't know which parts to move. Does anyone know of any sites that have a picture of the xda II mainboard? I'd really appreciate the help.
Help - the connector into which the charge cord needs to be plugged is not making contact and so can't charge G-tablet. Any suggestions? Has anyone opened one yet to get inside?
Thanks for any help.

this is a thread with a hardware breakdown, should come in handy. I've never taken mine apart but it looks easy enough.

Been there, done that... You do need to crack it open (gently of course) and the thread above does show to do that. Once you're in there's a metal tab that you'll see within the power connector assembly but from the side (do NOT go through the connector hole). Once you see that, use something small to push it in about 1/8-1/4". You should get connection then.
Be warned that it will most likely stop working again as that tab is now weak(er). I'm going to see if I can find a better connection option for that or just resort to charging on a dock.
As you may be able to deduce, I've had the same problem.
Warranty Repair?

Have you thought about sending it in for warranty repair?
G Tablets have a one year warranty so it has to still be within warranty.
Call Viewsonic tech support. Their phone number is on their G Tablet page on the web site.
Hi guys. This is gonna sound awkward. I'm having issues in my personal life and I was talking on whatsapp with brother when I got angry and threw my nexus. the screen is broken like colors and stuff and lines so I tries to turn the phone off by touching where the power off button appears on screen butI couldn't.
since I was angry I removed the back cover and cut the golden wire at the bottom point where it turn. I've tried turning it on by holding the cut ends but no luck. tried charger too but nope. All I wanna do is get into recovery somehow (TWRP) and dump my internal storage.
Thank you.
After some thought about your description.... I wonder if you have actually cut the main ribbon cable from the microphone/speakers/USB assembly this is the one that runs down the side of your phone. your best bet will be to purchase another cable assembly.. since you are dealing with a multi conductor ribbon cable.
I really doubt that you will be able to repair and re-connect the cable without some pretty highly skilled soldering ability.
The battery cable is very short and comes directly out of the battery itself... it is not likely that you actually cut it but did cut the main circuit cable. Too Bad, but this will be a real problem for a repair.
no joy... but you might want to investigate a reputable repair shop.

Thanks so much for replying. Yes indeed I cut the ribbon cable. I'm in no position of buying a new one. I guess I'm gonna take it to someone with high soldering skill. Before that I'm gonna try tape too

Question: if this ribbon isn't battery wire then why the phone doesn't start
main connection cable ( do NOT cut)

That ribbon cable is the one that interconnects the working boards in your phone, Microphone, Speakers, buttons. Unlike the battery cable you probably won't be able to fix it... it is pretty much a replacement only part.
this part is called -- LG Nexus 5 D820 D821 Charging Port Flex Cable Dock Connector USB Port With Mic Microphone Flex Cable Repair Part (amazon.com)
you will have to source a supplier close to you... but the good news is that it is relatively inexpensive... Ebay has it listed for $10USD or so.
not trying to be the bearer of bad tidings... but I've spent 20 odd years repairing computers and associated devices. It is always best if you don't cut ribbon cables.
Hi! My mother's S7 is not recognized by any PC right now. Before I order a new USB PCB I'd like to ask for some help here. The symptoms are:
- Charge and fast charge fully working
- Everything inside the phone is workin, not a single scratch
- When I plug in to any PC, no data mode transfer appears, neither under quick settings, just charging.
- Windows doesnt recognize anything when the phone plugged in, seen on device manager.
Did you install the Samsung USB drivers?
9 times out of 10 it is the USB port. This can be replaced by dismantling the phone and connection a new USB ribbon.
If you have tried this and ruled out the port, I had one where a dodgy charger had fried some components between the USB ribbon connector and the multiplexer IC. I had to replace components ZD8008, ZD8008, R8019 and R8020. These serve as input protection on the USB data lines.
Someone with microsoldering repair experience will be able to replace these for you. You be no more than 75 Euro. It does involve dismantling so may void warranty/water resistance.

I guessed so. Where can I find this components? Are they smds resistors, capacitors? I know microsoldering but does it deserve the effort? I mean, can I found a USB pcb replacement and just replace the whole piece?
Thank you very much!
EDIT: Like this one
EDIT2: I missunderstood your first line...I haven't already tried to replace the usb pcb. I think I'll try and if it doesn't work, well... I hope not -.-"
I draughted this reply before I saw your edit; sounds like you know what to do though: :good:
Sorry, it never occurred to me that you hadn't tried a new USB port flex yet. 9 times out of 10 it is that. Get one to try; fitting it is a pain because you have to separate the screen from the mid frame for the back/app button backlights but you can test it without removing the old one. They are very cheap and available on eBay etc.
If the new USB doesn't help, the fix is probably the microsolder repair I described above. Those components are in the main PCB so a USB daughterboard swap won't help.

So before my xz premium completely stopped charging my phone used to randomly stop charging and charged very slow I used quick charge 3.0 and certified usb c cable I had to put the usb type c cable in a certain position to get my phone charging but after a while it completely stopped charging I inspected the port it was fine no bent nor broken cleaned the port but it didn’t charge after sometime I started messing with the phone so I found a way to charge it when I put pressure on the bottom of the phone from front and rear of phone where usb port and flex cable is connected it starts charging but I have to put a lot of pressure to get it to charging I don’t know about hardware so I am here If someone can guide me ty.
Is the charge manager enabled?
In this case the manager try to think at which time you disconneythe the phone from charger and stopped after a while to continue in front of disconnect (or what he think at which time it is)
No the charge manager or (Battery Care) is not enabled but I opened the device myself because I thought it might be a loose connection of charging port's flex cable but it was connected to the motherboard fine but the situation was the same I pressed the flex cable where it connects to the motherboard and the phone started charging I think it's some sort of motherboard problem as it happened with some other xz premium users as well.
P.S:Replacing the charging port didn't fixed the problem.
Hello,
I had a similar problem.
At first it only carried in certain positions or pressing the region where the flat connection. After 1 months it stopped completely.
My problem was in the motherboard charge connector, I needed to buy a new connector to replace with solder. After 30 days, everything continues to function normally.

Thank you very much that's the answer I was looking for one more thing can you guide where to buy the connecter for the motherboard and can you tell me how did you manage to replace it.
Update I just got mine fixed the btb connecter for the charging port on the motherboard was loose it needed to be resoldered in case it is more damaged you should get a new btb connecter I'll put the link to buy from link: https://rounded.com/sony-board-connector-btb-socket-2x10pin-1306-0093.html
can u guide me how to do it?
If u know any trusted and skilled repair person just tell him what the problem is and make sure the repair person fix it the right way as described otherwise he might end up damaging ur phone.

Changing the port won't fix the issue it can only be resolved if u change the btb connector on the motherboard.
Anyone knowing how to do it?
Hi. Stripped phone down and removed old BtB connector. How do you solder the new part to the motherboard. Is it just the four corners you solder or do all x10 pins on each side need to be soldered?
Can somebody who has changed a BtB put a step by step guide if poss?

ok update i've been trying to repair it/solder it in a couple 3rd repair (because there's no sony xperia service center here in indonesia..) and they say they can't, then i wen't to this repair shop (this one looks not promising) then i got a message after 3 day they say they can't repair it, i was hopeless, i left my phone there.., and after 1 and a half month i think, i finally went to get my phone, and when i arrives to get my phone they charge me 15$, in my head i was thinking "why they charge me? they didn't even fix it"
then the repair man said "we fix it" i was shock they didn't even message me and said it was fixed (they have to) so i pay the 15$ and check the phone its completely normal it's charging the fast charge work, but.. they reinstalled everything (factory reset) kinda strange.. but it's find ok so that's it
