Replacement LCD Ribbon/Flex Cable

Hey guys,
Long story short, I'm an idiot and have slightly torn my LCD flex cable.
Does anyone know if it's possible to repair or replace this cable without having to purchase a whole new LCD?
If they're replaceable, any suggestions on where I could purchase from?
Cheers.

I don't think this site has what you are looking for but I don't know the inside of the Atrix too well. It has 2 cables to choose from, maybe one will help.

It's impossible to change the Flex Cable of a LCD Screen. At least, that's what (at least) 20 electronic technicians said about changing the flex of a N97 screen to a Satio Flex cable - my last phone (now it's an Atrix).
So, I'm sorry, but I guess you'll have to get a new LCD.
- I'll search for an alternative.

Good prices, but problem with GDP is they require at least 2x purchase of every item or a min $150 purchase... So not much good for the average user.

Thanks mate. You're right. Has 2 of 3, but unfortunately these are not the droids I'm looking for. I'm bookmarking that site though, as it's hard to find those other 2 flex cables. Cheers.

Hey Erich. Yeah, I think you might be right. After pulling my old LCD apart, i doubt anyone could attach a new cable without professional equipment and a brain surgeon steady soldering hand.
I've given up and ordered a new LCD.
Thanks everyone for your help though. Moral of the story, if you're gonna bust a cable, make sure it's one of the accessory cables instead.

Bad charger port

I think I mite got a bad charging port. Is there a way to fix it or is it time to upgrade?

Is it just when your charging your phone or is it every time you plug your USB cable in? Have you tired different cables? i thought that same thing too and it turned out to be a bad cable.

Coming from the htc family, do the s2 charge ports seem to hold up better\longer?

My wife and I have had our E4GT for eight months now without any issues. I've had several other Samsung phones in my many years and never had any build issues.
Lol I even ran over my wife's phone once! Other than a few scratches there were still no issues.

I'd try a new cord first. If that doesn't work go ahead and upgrade but send me your E4GT.

I've tried everything. I guess i can try to buy a new charger to make sure, before i jump ship

Have you tried the USB cable to the PC and see if that works. If you have bought a off market charger or so, then there can be issues. Try a blackberry USB cable if you have it and see if that works. Those cables are pretty good.

Worst case scenario: Port is shot and gets no charge whatsoever = call for insurance replacement.
The port is integrated to the mainboard inside so there is no "fixing" just the port, even local cellphone repair shops won't touch it. If your phone is insured they should replace it. When I WAS with T-Mobile they replaced mine free no questions asked b/c it had been in a flood. Phone was still 99% functional other than the fact it could not charge b/c the port was shocked out. Hope this info helps

Have you gone to a Sprint service center???
Had the same thing happen to me a couple of months ago. Took it to Sprint and had a tech look at it. Got it replaced the next day.

No fixing it? If the port was just over stressed you can pretty easily solder any broken pins back on... if the port is completely shot its not that that hard to lift the broken one and replace it with a scavanged micro USB port... I just replaced a busted HDMI port on an Xbox, same principal....

Loose mini USB port

I just noticed my mini USB port is fairly loose that when the usb cable is angled at a particular direction charging stops.
I tried the same cable at two other phones and no problem. I visually inspected the port and it seems the metal that surround and supports the mini usb broke at the side making the top and bottom part separate from each other. It makes the port not a snug fit but a losse fit... And so I wonder if anyone else had this issue? I've only had my S3 for a few months and I use it roughly the same as my old phones (yes, I do use it while charging) and they didn't have this problem... Is it really that easy to break or do I seem to be mistreating it?
Note: The small pointy thing is ok, so I can still charge and do other stuff. Only issue is that it's a loose fit.

I was just dealing with this last night. It may be a little flimsy. Hopefully it doesn't get worse

I know... If it gets worse, I hope I don't get caught somewhere having unable to flash a stock rom via odin... To claim a clean warranty... Afterall, the damage is on the hardware and can be seen outside

Is it the original cable? I know my charger cable is stupid loose but my USB cable is fine.

If it is actually damaged, why not get a replacement now?

I'll have to check with Wireless Wave where I bought the phone... Because it's either they send it for repair which would take weeks and they'd give me a crappy temporary phone... Or if I'm lucky replace it on the spot... Which I doubt... So I'll have to weigh in the options... It's not much of an issue right now but pretty sure it will be soon enough so I have to ask them soon... I'm just doing some poking around to see if other people experience this as well if it's a fairly "common" issue then they might give me a replacement if I tell them fixing wouldn't help because it may just happen again.

volume flex

Dear,
Today i was trying to replace my oneplus one camera, but to be able to do that, I had to remove the motherboard.
But, when trying to do so, I broke my volume flex cable ( please dont ask me how .. )
I saw a flex cable on Ebay. but the cable it self is soldered to the motherboard,
is there any way to get that loose?
Keep in mind, I dont have a solder at home.
Please help me!

what you need to do is welding it.it is very easy.

here its very easy to do.but you may cost more money to prepare an electric soldering iron

It is the gold thing next to the qr code.
Do I need to detach that whole thing, including those gold pins?

There arn't any gold pins. However desolder the 3 Pins and pull of the flexcabel, afterwards place the new flex on the port, put some soldering flux on it and then start the soldering process.
There is no way to put a new volume flex on it without equiment...

Yes, i mean those 3 pins. Can i safely desolder them? I'm very afraid to break someting..

Well it depends on your skills, so i can't tell U if its save. Ofc u can break something when doing it wrong, like put to much temperature on the board but it will likely not happen
Atleast for me, its safe and easy to replace such parts.

buddy of mine is a miracle worker when it comes to soldering stuffs in mobile motherboards, i had my oneplus's back cover removed for some reason and ended up poking the screw tool on the flex, only one of the line got a dent and the keys stopped working, and he did his magic by bypassing the damaged line with a older droplet.
there must be someone around you who is real good with their hands, try someone/place where theres no rush, who might have plenty of time on these kind of tricky works.
good luck.

[Nexus 7 2013 16GB-Wifi Model] Help with Nexus 7 Logic Board.

I have a Nexus 7 2013 16GB Wifi Model, and i bought it to a local repair shop. But it seems i was ripped off as the repairman could not repair it.
I noticed that some of the circuits are missing from my Nexus Logic board and Nexus no longer boots up.
Can anyone please help me determine these circuits? Here is a picture of the logic board.
All that is marked with a yellow star in the picture is what i am asking about...
Code:
drive.google.com/open?id=0B7LGwJIcFvH1WUtyNWZSTnhYRFU
And also are these parts important? Will the tablet work even without it? Where could i get a replacement of these parts?
Thanks in advance.
P.S Sorry for bad ernglish

What was the original problem? What is the board's revision number?
If it is rev.1.4 and the components are unsoldered/missing, then you were indeed ripped off.

Yeah mines the same revision to the picture you attached. (ME571K_MB Rev 1.4)
The problem was that my nexus was charging really slowly but i didn't really put much attention to it. Then one day while charging my nexus i accidentally dropped it and the charging port went loose so i sent it to a local repair shop to fix the port.
The repairman said the charging ic was also the problem. but then after a few days they still couldn't repair my tablet.
They returned it looking like a mess.
battery wires were a bit chipped off. (No problem here, i used a tester if it still has a connection to the board)
the charging port was soldered upside down.
copper pads covering the circuit was removed.
some of the plastic parts on the speaker looked melted probably due to the solder mishandling.
So is there still a solution to the missing chips?
BTW. Thanks for the reply.! :good:

The charging IC is probably gone if the port was soldered upside down and powered up. The missing components can not be identified because N7/13 circuit diagram is not available. A working, second-hand N7 motherboard can be purchased for $25 on eBay and it's the cheapest solution. Let us know how it goes....
:fingers-crossed:

Oh ... so it's really busted huh. Thanks for helping me out.
But buying another logic board isn't one of the options i have.
I guess that i'll have to sell it somewhere then.
Thanks again.!

Sell the daughterboard after you fix the port, it only has the touch IC and should be good. Those are worth quite a bit. So are the screens especially if you include the frame. Just selling those separately should be enough to get you a n7 2012 or even a 2013 if you get lucky.
