Story time first, then the question.
Okay so I have a tablet I got replaced by the recall, and I'm going to say it - I'm not gentle with my devices. That's why I made sure to have a case on it at all times. The other day I was trying to pick up my tablet in the dark because I had put it on the floor for a second to get it out of the way to turn off the light to go to bed. I found the cable it was plugged into and slowly started picking it up by the cable. I know, I know, but it worked, almost. About three inches off the ground it came unplugged and dropped, then fell flat on the display side. When I tried to turn on the screen to use it (I'd done that before so I didn't think it would be a big deal. Besides, this is a tough little tablet - my brother left his on top of a car and drove off and when he got it back there was a little cosmetic damage and not even a cracked screen, even though it hit on the corner) the backlight came on, but nothing came on the display. So then I took it to a local repair place to get an evaluation done. The display cable had come unplugged, nothing more. Just needed to get plugged back in. For $30. HA! I took to the internet to find a teardown I could use to fix it myself and save the money. But the video I found didn't have any words, spoken or otherwise, so I ended up just having removed the battery and mobo and putting everything back in. Well, it worked. The display came back on and I had my tablet back. But the warning that my card wasn't in came up and when I figured it out, it turns out when I had lifted the mobo, the card slid out a little and when I put it back it snapped the card, so now I need a new one. But now once I put it back together there's a new problem. When I plug it in to charge, the led flashes green and yellow, but it doesn't actually charge. I guess I somehow knocked loose another cable or something while I was in there.
Okay now for the question.
Does anyone know of a diagram of the connections or a teardown that labels things I could use to more confidently get this tablet working again? I think I mainly just need to know where the charging circuit connections are. I'm pretty sure of which one I need to plug in correctly to make it work but I'm a little gunshy this time and would rather know for sure. The battery is down to 11% and it's off right now, but I use this thing too much to do without a tablet for long.
I got similar problem, my 3 year old son dropped his tablet couple of times accidentaly and suddenly we could not charge it anymore (orange/green flashing). I have a replacement battery prepared for my pyro tablet (his tablet is the replacement), so I decided to replace the battery. Once I opened the tablet (you can use this guide https://www.ifixit.com/Guide/Nvidia+Shield+Tablet+Battery+Replacement/50117) I found the green wire for the battery PCB detached from the main board . I soldered it and that's it, now it works again!
Now, I found that the new tablet is different that the one showed on ifixit, do you guys know what is that circuit installed on the tablet back cover?

Hey, Just thought I should post this... To reset the Captivate without removing the battery, there is a connection on the board called "TP". It is right below the MMC card and you can barely see it with the phone's case on it. Here is a picture of the rear case removed. The TP is the white dot. It is covered with white paint to avoid accidental connection.

You can stick a needle through and ground "TP" to the side of the SDCard. Your phone will reset.
It's a signal line. and it's separated from bat+ by 1000ohms.
Thats very useful. Thanks!
Will this reset work on "soft" bricks and/or paperweight states?

It will work on soft bricks. I'd like to see how a hard brick would react to UART communications. I've got one comming, so I will be able to tell you more soon.
This is a great find for flashing addicts. Thanks so much for sharing this. When I get to my PC I will hit the thanks button.

I've found it quite useful... but I've been doing some non-standard things with my phone...
That looks sick! Someone's been having fun. Has your phone orbited the Earth yet?
Haha not quite... I've been researching non-invasive methods of recovering bricks, and it requires invasive techniques for analysis. Its amazing how many people brick their phones and how expensive jtag methods are.
Doesn't work on Hard Bricks. Tested.
So is it possible to fix a soft brick using this method instead of making a jig?
On my way home right now, guess I will find out soon enough, thank you
Wasn't quite sure what it was gonna do, and hoping it would magically get me into download mode, where the usb or power wouldn't. big down side, it botch'd something in my hardware, and my battery will no longer charge, can not run the phone without being pluged into the wall or pc. unbricked using a standard ol jig, flashed to 2.1 via 1 click, dunno if it just fried battery or did something else. Any ideas what to trouble shoot first? i've tried reflashing, few different roms, tried reseting battery stats, tried factory reset via settings, and via 1 click with no luck, wont be able to test another battery till tomorrow

You did something else....
I used this method about 50 times consecutively. No ideas for you on your issue.
This reboots the phone and that's it. Its easy for bench testing purposes. How long did you hold it?
Just until the screen shut off, then released, not really what sure happened. Is there something rom side that controls the charging of the battery or is it strictly hardware?
Just hoping battery just decided to die, needed excuse to get a bigger one anyways.
Edit-Yeah definetly thinking battery is bad now, it showed 100% charge this morning finally, but as soon as i unplugged from wall it died, plugged it back in and was showing it dead again. Soo hmm, dunno sound like bad battery? fixin to make the 30min trip to ATT store to see if they can check it or swap it.
just wanted to say, i wasn't trying to imply the reset you pointed out had killed the phone, i just wasn't quite sure what happened, and this had been one of the last things i had done.
I just didn't realize a battery could go that quickly, had it tested today, and the guy at store said i was the first person he could tell without a shadow of a doubt there battery was dead.
1500mAH battery, and it read dead at first then full charge on tester at 28mAH.
This looks very interesting and I would like to try it out. Before I try it, I was wondering if you could explain it more in depth like if the battery should be in the phone, if it is necessary for the battery to be fully charged and if this method will work on all Captivates. I also noticed a number on your sd card slot that is different than mine but I assume all phones have a different one. Thanks in advance
Turned off my tf last night to charge. Turned her back on now and the boot screen is neon green and so is everything else. Anyone have this problem before?
either overheated cpu/gpu pover off for a couple hours then turn it back on
or digitizer cable is loose either open it yourself or rma
i just took some screen shots and opened them on my computer. The colors are normal. Ill try the power off for a few hours and see what happens. Any other suggestions?
ok if the screen shots are normal that probobly means something is wrong with teh screen its self as like i said before loose digitizer cable
My TF was turned off all day today and is still giving me the green screen. Here are some pictures of what I'm still dealing with.

I actually had the same problem and I jsut turned it off for a couple of hours and it went back to normal
Yeppers... me too.
I noticed some green digitized flickering yesterday when I was moving/angling the tablet while docked. When I opened it, the green digitized color would flash and then go away. I undocked the tablet, powered off and restarted.
The green color was still present and it seemed to go and come as I pressed into the screen. It was almost like the screen was loose a bit from the casing. I did a hard reboot followed by a factory reset. Still the screen was flickering with the green digitized. I found that once I ran my thumb around the edges ensuring that it was tightly fit inside the casing that the screen went back to normal.
I never lost any function or touch sensitivity but am certain that my screen was loosening up abit from the casing. I mailed it off with RMA ticket today. I hope they will fix my tablet and return it soon or replace it.
Tablet has never been dropped, but I do dock & undock often. Furthermore I've found that while docked the tablet wont open much beyond 90 degrees. I'm wondering if me constantly opening it up to it's maximum angle while docked weakened or stressed the casing and loosened the screen. Not sure.
I could not find a bunch of these issues with the TF101 so I'm hoping this is not symptomatic of this model with heavy dock/undock use.
What's the normal turnaround time on these RMAs? Any ideas?
I had sort of simular problem with my transformer. After charging my screen was green and pink.
They will fix at rma because it is backlight leaking. Thats what my report said.
The service wen i sended it was fast. Send on tuesday and 7 days later the allready mailed it back with a new screen.
Mine, definitely had some light bleed around at least 3 sides, but it wasn't distracting so I just ignored it. Hope to get it back soon and without any further issues.

Wait, I can send it in for light bleed?
On a black screen I can see bright spots in the edges, apparently where the backlight is.. I figured it was normal.
Also I have 8 or 10 stuck-on-white pixels. You can't find them unless you have a Black screen. Can I RMA it?
I just got back my son's Transformer from repair after his screen did the same thing only his was red.
Called in to get RMA but was told to do a factory reset first. That, of course, did nothing so back it went. Seems to be fine now but it has only been back a day.
You should have no problem getting it approved for RMA.

It might be a problem with the screen connection
So I dropped my phone in water a few days ago. After leaving it in rice overnight, nothing seemed wrong except for the fact that my volume down button didn't work half the time, and sometimes it would go off by itself (I would be browsing on my phone and suddenly the volume would go all the way down by itself, as if someone was holding the volume down button). The problem disappeared soon, so I forgot about it. But today, when I tried to change my volume, it wouldn't work at all, so I decided to restart the phone to see if that would fix it. Bad idea, because now no matter what, the phone always boots to recovery. It seems like my phone is registering that the volume button is always being held down, so every time I boot it up, it goes to recovery. Is there any way to bypass this? I can still press down on the button like I normally would be to, so it's not physically stuck.
Pop the back off of it and check the volume down tab to see if its physically stuck or not. The moisture may have caused some corrosion buildup in the tiny aluminum piece that gives it the spring back when released. If its stuck you can try and play with it to see if it'll come loose or try replacing the ribbon cable all together.

Did you get yourself some Bacon? Haven't seen you since my early Evita days.

Yep, frying bacon good to see a familiar face. I've been on nexus 5/6 forever and steered away from HTC/Samsung. The oneplus is hot tho, Google is going to need a miracle device to get me back! Asus has me sold tho, I'm 4sure grabbing one of their new zenphones to tear into and explore!!

Hey, thanks for the suggestion. I've opened the back (which was painstakingly hard), and the button seems to be fine. It seems like there's no difference between that one and the other buttons - it still springs back up when pushed. What do you mean by replacing the ribbon cable? Any other ideas?

No, I come here and mostly just read thru the forums. My schedule isn't as nice as it used to be so I don't get to play much anymore. I'm looking forward to the zenphone tho because I'm thinking the x64 Intel processors will re-light some new excitement for me.

I would probably remove the motherboard and sister board and give them a close look over for some sign of damage or corrosion and maybe use a q-tip with rubbing alcohol to wipe over any I find. Just don't get it on any around the base of the chipset. I think the ribbon cable is soldered to the board if I remember correctly so replacement would be difficult. If its not, replace it.
Hello. Somedays ago my nexus started to freezes on a static colored screen, just like this one:
~~sorry for the big image, i get this on google since i dont have other phone to take this photo~~

Well, my screen was also cracked so i decided to change it, because i was thinking on that moment that this is only a problem in particular with the screen
I just let my Nexus lying on my secure table of things, not using it minding not mess it more (as far i know that my little poor Nexus 5 has a problem on Microphone too)
Life goes on, mailman gives me happy bringing the new screen in less than 1 week, then i installed it on the same day.
but, the problem of "HBO" screen noisy continues. And sometimes (very rare) the touchscreen stops working. I make some research and i found it that can be the flex cable of USB charge (also same flex for screen and mic as well). This flex cable is responsible for connect screen, wifi antenna, mic and usb port to the motherboard. Replacing it could fix, i hope.
Before i buying the new flex cable, i have to make this question: this problem can be a faulty motherboard? any minor chance to be a little fault on motherboard? or i can assume that is only a problem of the flex cable?
This is the flex cable im talking about: http://www.ebay.com/itm/Charging-US...444535?hash=item25bb6f9ef7:g:0-wAAOSw2x1XKKJy
Thanks in advance
Since this happened on the old and new screen, it could be a problem with the internal connections or, worse, the motherboard.
solution?

got it fixed? solution please?
I have a problem. Due to frustration, I hit my Redmi Note 7 pro to the edge of my bed . This made a dent in the phone. And now the phone is dead. Unable to fastboot. Not charging. Its completely dead. Tried to Unbrick but the mobile is not detected by Adb bootloader too when connected to PC. Any sort of help would be appreciable. Thank you.
Maybe socket battery not connected (displace)

I am not sure about that ,but before the incident happened , it was charged. Also holding power button or "power+ vol up'" button doesnt show anything. If it was battery issue, I believe atleast the mobile would have turned ON for a second

well it depends on where the dent is on the phone if the dent is at upper portion (near camera)
then it is probably dead motherboard and even it was on the battery side (around "REDMI" logo)
then there is high chance that your device's battery will get punctured and it will caught fire or something
worse and it is also applicable to front side of phone. but there might be a chance that from the dent only
the screen has stopped working, in that case you can replace the screen and it will be fine.

Thank you for your kind reply. This was helpful . By your explanation I suspect that the mother board is dead. And for clarification I have attached the pic and highlighted the effected part. Is there any solution for this? What can I do if mother board is dead?
