Has anyone replaced the flex cable for the two buttons? I'm just wondering if anyone was successful, and how difficult it is. I have my watch taken apart down to just the motherboard, but I'm not sure how that cable attaches to it.
Thanks
The ribbon cable is soldered on.
I have been told it is not a very difficult job.
I have the broken power button issue but I am hesitant in replacing the cable as I don't trust my soldering skills.
Perhaps I will replace the whole motherboard.
Have you had any luck with this issue? What did you do- replace the motherboard?

Alright; so the connector where you plug in the ribbon cable for the mic, the white fastener that
acts like a breaker decided to fly off so my mic doesnt work. If I put solder in the area where the
fastener was; will that make the connection work and therego make my mic work again? I really
don't want to buy a new mobo, I just bought a new lcd and digitizer...... response asap would be
greatly appreciated!

Not unless you can solder the individual cores of the ribbon cable back onto the right place on the motherboard, no.
I took my TF700 apart last night as the digitizer was not working following a drop and assumed that a cable had come loose.
Anyway, made a mistake while doing it.
I could not disconnect the cables between the LCD and digitizer and the connectors.
I since realise that there is a small white bar that you flip up. I presume I have "broken" the connectors or something as the tablet works fine when plugged into HDMI, but I cannot use the digitizer and the screen does not come on.
Any suggestions? Most that I have found have suggested "throw away and buy again as spares too much", but wondered if anyone had a bright idea.
I have found why the digitizer was not working, there is corrosion over the SD card and around the top connector to the digitizer nearest the SD card slot. It looks like mositure/drip got into the slot and may have shorted something? I have cleaned off the surface debris as much as can.
Anyway this would not impact the LCD which still displayed (until connector concern.)
Following that, is anyone getting rid of their TF700 and would be interested in selling it at a sensible price?
Thanks
If you didn't pull that white bar off or break it, it could possibly be that you have not properly inserted the ribbon cable and fastened the connector. I would open it again and check this before I did anything else.
Most of them work like this:
Open it by pulling at each end of the white bar until it moves foward a little, then gently lift it to about 45 degeres and the cable slides out with a slight tug. Putting the cable back in is the reverse. That bar has to be loose and at about 45 degrees to get the cable back inside the connector. Make sure the end of the cable is in straight and close the connector. Cable should be tight and not come out if you gently tug it.

Thank you for the suggestions, I have tried that, but none of the 3 connectors (2 for digitizer, 1 for LCD) respond. I connected it to the HDMI, but cannot see the screen respondin to my finger (maybe that is broken also ha ha)
Is it more likely the connector, or cable is broken? I suspect connector pins to be honest. Abit small for me to see though.
Digitizer or Ribbon Cable or ZIF socket ??? How to tell ???

Greetings!
Just curious how this problem worked out? I too have a TF700 with a working screen but no digitizer. Some time back during my first battery replacement (another story) I tried (we ARE a curious species you know) to open the ZIF socket for the digitizer cable (has twin, gold ribbons) and accidentally flipped the wrong side... needless to say it did NOT flip open. The black plastic top of the socket broke off exposing a little of the ribbon. Everything still worked fine so I counted myself lucky and closed her up and all was good.
Unfortunately I'm never willing to leave sleeping dogs alone and I attempted to replace the 2nd dud battery with yet another one (don't ever trust those "Brand New" eBay batteries)! This time I must have accidentally pulled on a ribbon cable a bit too much. When I closed up the tablet I ended up with a tablet just like yours... everything works great... just not with my finger! I opened it up AGAIN... to replace the original battery... you never can tell you know... while I was in there I tried reseating the digitizer cables (both sockets)... no luck.
So... now what... I'm hearing that some folks had their digitizers fail after about a year anyway... mine is two years old... so my digitizer COULD have just failed... or it COULD have been my messing with the ribbons and/or ZIF connectors. How to tell ??? Is there ANYTHING one can do short of ordering a replacement ZIF socket PC board ($25 eBay) and / or ribbon? With a two year old device I'm reluctant to spend much on repair... ASUS wanted $184 to fix it... and buying an eBay digitizer or ZIF board on the blind chance that one or the other is the problem seems a bit risky.... to say nothing about the chance of mucking up the heat separation of the LCD/digitizer! What's a digital explorer to do???
The only thing I was unable to determine was where does the forked golden digitizer ribbon cable GO on the glass end. Does THAT end ever come loose? How does it attach to the digitizer? Anything I could "fix" on that end?
I was replacing my screen for the 3rd time... yes that's right the 3rd time. I don't want to talk about it. I thought I had released the catch on the motherboard connector that the volume button plug into and when I pulled the cable I yanked the connector right off the motherboard. I have been surviving with a volume app for a while, but I want to fix it so I can sell it for more monies. Daddy wants new note edge.
I am not worried about the work itself, it won't be a piece of cake but I have the right tools and a little experience with soldering small bits like this. But my google-foo has failed me I can not find this part. Anyone have any ideas?
Hi,
The connector on the motherboard that has the flex cable which goes to the smaller board down of the battery is partly snapped off. (imgur.com/BnYn0OZ left side) This also means my screen is disconnected... When pressing on the connector it will still work but when not pressed the screen is just blank. Can I fix this without buying a new motherboard, which is expensive as ****, or am I screwed?
Thanks in advance!

You can stick something (like little plastic sheets) at the back of that cable, so it is always pushed against back cover.
I fixed a similar problem in my old Canon point and shot digital camera this way

Thank you so much!! It works again!
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.
