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.

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.
Well I screwed up. USB Port started to not work and when I pulled it apart the Port Ripped off of the main board. It actually damaged the pcb where it ripped the tracks out. So I'm unsure of what to do. I just bid on a broken screen KF2 on ebay.
But Wondering if anyone knows of where I can get a broken KF2 that prob has this part?

Just send it back to Amazon and they will send you a new one, Just say you pulled in the cable, nothing happened, went to remove it and the port broke away from the PCB, Should be covered by the warranty.
Its rooted and on JellyBean!
lol just got off the phone with Amazon. So the lady guided me through some things and then we go to plug it up... the damn Tablet Charges! WTF! lol I guess the Data connectors were the ones damaged (I did try to resolder but the only ones that would were the two outside).
This is Bew Shhhhh lol
Yeah two outside pins are power, and you voided the warranty buy opening it and soldering on to it, live and learn, eh?
I wanna cry! Even tho its not the best device I've had, because the crap memory and no camera.... but besides that, this lil thing rocks on CM10. Powerful, Smooth and no flaws. I am gonna try to get as much for it as possible. It still charges so thats a plus. Only way to transfer data to it is via wifi, google drive and so on. Hopefully I can get enough for it in its condition to pickup another one with some additional cash.
Hi guys.
Recently, I had to change out my micro usb charging port because the previous one stopped working. I don't know if it had to do with heat issues and messed up the soldering. Sprint said it was because of water damage, but I'm very very protective of my phone and have yet to have any contact with water in it.
When I got the piece, I figured that I would make a video on how easy it is to replace the piece. I've never contributed to this site, so I figured I'd like to do something
I ordered the flex piece from this site for $11.
http://phonepartsusa.com/product-ty...te-2-l900-charging-port-flex-cableflx-sam-681
Never done something risky like this before, but it sure was rewarding getting it done. In the mean time, when I waited for the piece to come through in the mail, I bought a charger from Ellis batteries for $15 and a separate battery. I wonder if I can return it :3.
Hope it's helpful

Alot of my friends had this issue, and so did I, luckily I was covered by warranty. But I was f***ing heartbroken when it happened. When/if this crap happens again I will know to find your post. This is freaking awesome!
I almost feel like samsung knew they put fragile ports and crap in the phone because from what ive noticed most of the components are attached with ribbon cables instead of soldered. I ordered a new headphone jack due to worn out pins, and I wont be suprised if I have to replace the usb port one day.

Awesome It was a crap feeling that I had to dish out $50 for a battery and charger that was only temporary (guess I'll be using the extra battery as a means of emergency power, especially when going downtown)
m4xwell - I think it sort of goes both ways. Essentially, the pieces being easily replaced was in fact a smart idea. Of course the downside is that the pieces are a little more fragile as you said. Thing is, with the constant wear and tear in plugging in the charger, I would imagine that the ports would get worn out in a matter of time. I feel micro usb vs mini usb has some weird differences, with the micro usb being more fragile. My old nokia and LG flip phone had zero problems with the charging port. Guess the dinosaur age is still king

Hi all,
I recently damaged the micro usb socket on my Nexus 7 2013, which stopped it from charging. After some searching I found a replacement pcb (daughterboard / lower motherboard pcb) from Asus parts. I fitted the board and the tablet will now charge. Unfortunately the touchscreen is now completely unresponsive!
At first I thought I had damaged the digitizer or ribbon cable in the disassembly process, but to check I re-fitted the damaged board. The touchscreen worked again!
So I now wonder if there is some issue with swapping boards on the Nexus 7 2013. I checked the part number etc of both boards and they are identical. So I'm confused as to why this problem has occurred.
Does anyone know about this issue and how I can resolve it please? I have been very careful in swapping out the parts and cannot see any damage to any components.
Any help would be greatly appreciated!

So does the screen work or not? You probably just had it temporarily not detected by the system. Had you tried holding the power button for a minute to force a reboot?? Probably would have worked.

Thanks dottat, but that does not seem to cure the problem. It's a weird one. The screen is on and displaying as usual, just no response from digitizer. Do you think it is possible that the board is simply faulty? It seems unlikely seeing as it will allow the Nexus to charge, power on etc. Asus parts have agreed to send me another in the meantime so I will report back when it arrives.
Ok so the new board arrived today, fitted it with no issues but unfortunately the problem still persists. It is strange that the touchscreen works with the original board, there must be something I'm missing!
I know this isn't a solution to the current problem, but how about a wireless charger?

I took a risk last night and removed the damaged micro sd socket from the original board and replaced it with the good one from the new board. The tablet will charge now and the touchscreen is working, although it is very unpredictable, think I may have damaged the ribbon cable terminals on the board from too much swapping over.
I really need to get the new board working so I can make sure it is just the board at fault, so I know I haven't damaged the digitizer or its ribbon cable.

There are a few revisions of that daughterboard. On the board there is a stamp that identifies any revision. If it is the original it has no revision number stamp.
It sounds now as though you have damaged something other than the board such as the flex cable as you have suggested, but the incorrect revision model was the original cause of your digitizer issue. 99%.
Thanks.
Somehow I broke the white connector tab that attaches the digitizer to the left side of the motherboard. I've opened it 200 times before but this time the tab came loose from the motherboard completely. Does anyone have any experience with this issue.? Also the antenna port in the upper part of the motherboard just pulled off when i pulled up the connector so now that is completely unsoldered from the board. im starting to think this phone is done. any body have any recommendations? its basically just unsoldered connections..
