I've accidently cutted the PCB cable that connects the LCD to the motherboard.
How to replace it? Were to get it? anyone has a spare or used?
Please... I really need help, can't afford to buy the hole screen, need to fix this one.
Thanks guys!

cables that fragil and are mainly a plastic with either a conductive paint or copper cladding is not a repairable thing other then replacement, a few have suggested searching ebay as you can get a replacement screen cheap this may also apply to getting the cable only if it's detachable. but believe me I've tried this and i'm great with surface mount on the PCB direct soldering on the ribbon is possible but the wire type adn tools needed out weigh the cost of the LCD used or new

Hi there!
While replacing the speakre of my BA the lcd cable broke. But I already changed the lcd some time ago and now i have one broken lcd with a good cable and one good lcd with a broken cable.
Does anyone know how i change the cable?
Sorry friend, I had made the the same mistake; there's no way to replace it.
You have to buy a new BA lcd screen.
Well....
Some of those ribbon cables are attached to the glass via what amounts to glue. Electrical contact is done just by touch (no soldering).
At this point, I'd take apart one of the LCD's to see. It's not like you are going to make things worse if you break the glass on the dodgy LCD, it's already dead, correct?
Just try to post the results so the rest of us know as well!
yeah please post your results...
better if you have pics for it.
... im interested in "frankensteining" our BA's
hey guys, im in urgent need of a xperia play logic board, because my sim card slot is damaged due to a bent pin, can anyone that is striping their play and selling parts please pm me
Wouldn't it be far easier to just wire up the bent pin directly?
what do you mean? the actual pin is acctually like fullly bent and riped off.

I mean that you would make and attach a wire or something else to make the connection because it would actually be easier and cheaper than taking the whole phone apart and anyone with a soldering iron could do it. Now, that I have seen that the sim contacts are actually on a module, I see that you can just buy that module and not replace the entire motherboard.
sure? because its the sd card module that comes apart, not the sim slot, and if im to soder a wire, it means i need to unsoder the metal plate thats repaining the sim like the cop covering.

I see. I thought they were on the same module considering their proximity. If it means avoiding buying a new motherboard, I'd rip the plate off before I bought another.
hmm true true, would you know where to buy a new logic board?
Logic board? This isn't Apple dude. We don't use made-up names for parts to sound cool.
Anyway, if you check your local craigslist you might be able to find people selling broken ones for parts. Or perhaps Ebay. I've bought replacement parts for a LOT of electronics on Ebay.
And as CZroe said, you could probably just replace the module instead of the whole board, or if it's not part of a module, solder a small piece of wire.

alright, ill see, i dont think theres a craiglist in australia? haha but ill see, ill probably be going with sodering a wire onto the connectors.
Thanks anyway. and motherboard haha sorry.

"Logic board" is actually a pretty old name for any circuit board containing logic circuitry and components (doesn't need to be a "printed" circuit board or "PCB"). I hear it more often when talking about devices and "motherboard" more often when talking about PCs. I hear mainboard more often with older large appliances (think: "TV" or "arcade machine"). "Backplane" or "planar board" were actually really common ways to refer to a PC motherboard at one time!

Mainboard ive always called it

haha, i call it motherboard haha but yehs, so you rekon sodering a piece of wire or something wouldnt hurt it?
Provided you do a fine enough solder job, and it's conductive enough, I assume it would work.
On my old iPod mini, the molex connector for the button panel broke because those models had a defect in the design. I had to use a large magnifying glass on a stand (like what wristwatch repair guys use) and a sewing needle attached to a soldering iron to fix it.
You may need to do something similar.

outch, thats going to be painful.. you think repair shops will be able to repair it?
Possibly, but in my experience repair can be expensive.
Sent from Silent Earth 3
what was your problem? how much it costed?
That fix I did on my iPod mini was quoted at over 100 dollars at a repair shop, for both parts and labor. I fixed it myself without any replacement parts in an hour.
Sent from Silent Earth 3
wow... but the thing is im scared of burning any of the parts with the sodering iron. and what wire would i need?
I'd take a wire of similar width to the pin, and flatten it so it's the same shape and size.
If you do the soldering a little bit at a time, and don't hold the iron on too long, it should be ok.
Sent from Silent Earth 3
alright, thanks for the tip, so basically all i need is a sodering iron, piece of wire and side cutters to shape the wire?
Got my brothers old mytouch 4g with a shattered screen. upon replacing the lcd and digitizer I somehow broke the connector for the lcd ribbon cable. not sure how I did that it just seemed to crumble. does anyone happen to have a used one sitting around that they can sell?
just in case you can't find a cheap motherboard. can i buy your mt4g accessories? i need a cheap original accessories.

I have six of them, but they all have the bad emmc chip and have failed... So i dont think you would be too interested in those. so i highly doubt you will find what you are looking for as well, if it is in good shape, then why would they want to sell it, and there are few, if any other than me that have tried anything like hardware hacking these things...
is it possible to swap the emmc chip from one board to another?

not that i am aware of, check ebay for a board though...
the board i have now has a good emmc chip in it and works great except for the lcd connection point. the top plastic broke off to the ribbon cable is loose and it causes the screen to flicker real bad. ive looked online and a new board is around $120 new. im trying to get a broken phone off of ebay but so far they have all had bad chips.
Epoxy might be the dirty fix you need...
Me too!

I have the same problem. The LCD connector is all messed up after attempting to replace the screen. Did you find a solution?
Me too! Let us know if you figure out either how to fix it or where to get some good motherboards.
Well, In replacing my spring I broke the flex cable somehow. Kinda irritated at myself, especially since I have my old razr in my pocket, but oh well. I have one ordered on amazon, and my phone is setting on my desk torn apart. Unfortunately, how to replace the flex cable is not immediately obvious to me, as it appears that it's one ginormous piece , and glued down in certain spots.
I figured I'd do some research waiting for my new cable to get here, but I'm finding nothing. The tear down guide that was very helpful in replacing the springs and tearing it down to find the damaged part of the cable is of now help on how to get the cable off!
My first instinct is just to get something flat and pry up the glued parts, assuming that I'll be aligning everything when I get the new cable, but I thought I'd ask first if there is some better solution.
Well, for posterity, that really was all there was to it. There are several easy reference points on the ribbon cable as to how to line up the new one, if you're lucky there will still be some adhesive from the original. The only slightly tricky part is getting the Microphone seated just right, and getting the screen-> mainboard cable through all the slots it has to go through.
Also, an obligatory search bomb

I have Galaxy SM-P600 (2014 edition) which was the victim of poor repair at local shop... Now back has popped off and since the tech(???) did not glue down screen and it slipped and locking bar on mother board connector for LDC connector was damaged and popped out of "connector" and lost....
My question is where can I get replacement "lock bar" ... Rest of table is fine, just no screen becasue of no clamp bar on LCD connector...
Or is there a repair that may be not official but workable?

Hello Dale,
What you want is LCD´s FPC conector lock, and that´s hard to find.. Made a quick search on aliexpress, but couldn´t find it. I have bought lots of fpc connector from this seller , contact them, maybe they have what you want, but unlisted.
There´s an ugly repair you can do, but require good soldering skills: You can solder lcd flex directly to main board, not a task for begginers. I have seen some connectors like yours "fixed" with duct tape, it seems to work for a while.
Thank you for the reply... Looking closer, one pin on motherboard part of connector is damaged so I would guess its toast.... Unless I can get another motherboard, but that doesn't seem practical... The cost of this it ridiculous as it was $550 (purchase price) to begin with and I have another $235 after the first accident, now this..... Think I may just have to walk away from this...
Again thank you...
Dale
Just looking for a used or bad motherboard on ebay, then remove the connector and solder it to yours. It requires skills and equipment to this re work.
May be just look for another mainboard, depending on luck, I see someone list the used one for over $100.

usually beggining and end pins are ground, so it shouldn´t be a problem. just need a multimeter to check it out. if you spent $235, I guess you had to replace LCD. take it to the guy that made the mess, and tell him to work it out.
It is not going back to that person.... Bought a new one, I like the tab so well, and was trying to salvage this one....
Might watch for 32k machine with broken screen and maybe get something going, but for now its a basket case....
Originally I was going to do screen repair myself, now I wished I had...

Here is an used motherboard, you can replace it by yourself . I can take out the motherboard within 5 minutes as it has only 3 screws on two speakers to hold it.

Or this one, a completed tablet with flickering screen, this problem can fix easily by re solder the battery connector. You can use the motherboard and keep extra parts like LCD asssembly. An used LCD assembly can sell for $150 easily.
