[Q] Please help!fixed power and now no touch screen - G Tablet Q&A, Help & Troubleshooting

Please help, I miss my tablet.I had the common problem with the power thingy inside the tablet going out so i opened it to solder but did not fix.So i ordered the charging dock and waited for a month and a half.I get it today and was so excited to only plug it it and got power and charging everything is perfect,i go to swipe over on my arrow to unlock the screen and nothing!I have no touch controls on screen what so ever.But the soft keys work,they do not do me any good but they work.The home key takes me to my home page and mag glass goes to the internet.Does any body have any ideas of what could have happened or what i can do to fix this,please????

First, check for disconnected or loose cables inside the gTab.
Next, if it isn't a HW fault like loose cables, then connect the USB cable to the gTab and run this ADB command (you will have to install and set up ADB if you haven't already done so):
Code:
C:\SOME\PATH> [B]adb shell "echo -n 1 > /sys/devices/platform/tegra_touch/calibration"[/B]

The attached pdf contains photos of the digitizer/cables and their connections inside the gtab. Check for loose connection and/or broken wires on both ends.

Ok,First thank you so much for helping.Ok,One of the cables you shown does have two broken wires,it is the kind of short wire with black cloth like material over it that runs unde the shiny brown plastic piece.Is there a way to fix that or rig it to get me back up and touching again?Thank you again for helping me out,and you already pinpointed my problem,now i am hoping you can fix it,lol.

Where is the break?

I assume since you didn't send in under warranty for the power connector that it's no longer under warrantly!
Exactly where is the break? Close to (or at) one of the connectors? Which end (motherboard end or digitizer end) of the cable? Obviously closness to the connector makes it more difficult. I have seen a post where another use had the break pretty close to the connector & fixed it though.

I totally forgot that i made a youtube video yesterday,here is the address http://www.youtube.com/watch?v=kFNRtDhr5EQ I have been so stressed out about getting my gtab back it slipped my mind.Oh, the broken end is what plugs under the silver area not under the brown area.

If you magnify the digitizer circuit (lower photo in the pdf) you will see the label for each of the lines in the cable. Assuming the lines run straight thru, it looks like the ones that broke are the power & ground to the circuit (VSS & GND). That would explain the touch screen not working at all.
Hard to tell from the video where the breakis, but it looks real close to the connector.
Your best bet may be looking for someone who has a broken digitizer (outer glass) or gTab and is selling it for parts. I looked in the Marketplace forum here on XDA & there is one non working gtablet someone is asking $55 for. I also saw another one up for bid on ebay ($40 latest bid). You my have to ask if the cable is good on them.
Not a whole lot of options for repair. As you've already experienced, the cable is small & fragile.
If the connector has removable pins then you could remove the pins, solder the wire to it & reinsert the pins, BUT from the picture it doesn't look like they are removeable.
You could solder the 2 wires to the pins coming out the back of the socket but they look too small to easily solder to.
The last option would be to rigg the cable to work. There are a couple of possibilites but I would rather you consider the other options before suggesting a repair of the cable itself. If you can, see if you can take a closeup, high res photo of the back fo the connector where the wire broke. PM me & I'll send you my email address to send it too.

Its amazing what a couple of stripped bread ties will doo,lol.I took a bread tie and stripped the paper off of it,cut it to the length I needed and wrapped the remaining wire to one end and pushed the other end of the tie inside the pin hole,lol.It worked like a champ! MY Grab has been up and running for over a month,I just knocked on my coffee table,lol.Thank you for helping me out I really appreciated you trying everything to help me.I am so happy to have it back,now if I can just figure out why I keep seeing black boxes on my games when I play them I will really be doing fine.Thank you again.

[Q] HELP!!! broken black wire/connector inside HD2

Hello all.
While I was taking my HD2 apart to replace a cracked screen (glass digitizer) I accidentally broke the connector off one of the wires. The wire is black and a few inches long with a silver and round press on connector on each end. It attaches to the board that houses the vibrator motor and runs down the right side of the phone (if you were looking at it face down and partially disassembled).
Unfortunately, I lost the metal piece that broke off the wire (the thing is tiny!), so I can't just solder it back on. Any idea on where I can buy a replacement? I've spent about 6 hours today on ebay and google to no avail. Searching for "HD2 black wire" and anything similar is hardly efficient, but that's all I know about it.
Any help appreciated.
Thanks,
Chris
Good question, I think I damaged the cable to the volume buttons so it would be cool if someone has an adress where we can get spare parts except LCD and Digitizer..
this guy on ebay seems to be selling an HD2 in parts. you might find what you need here:
http://stores.ebay.co.uk/Right-Click-Enterprises/_i.html?_nkw=hd2&submit=Search&_sid=131407386
Thanks, I sent that guy a message and hopefully it'll work out.
Anyone else have a source?
connector of my hd2 is also broken HTC says that the mainboard must be change and I have to pay € 230 because that is my responsibility
I think you have damaged your coaxial cable connector for wifi and bluetooth. Google will help you perhaps.
I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
if the connectors on the boards are not broken then all you need is the coaxial cable with connectors on the two end. you need not disassemble the whole set, just open the back cover, connect one end of the cable to mother board and other end to the rigid flex board and that's it.

Do you think that this is my problem as since I dropped my HD2 I have no wifi (unless sat ontop of router) or bluetooth or fm radio, is it easy to get to the coax cable by removing back cover, whereabouts is it ?

Fixed it, opened up phone and spotted that at one end of the black wire the connector was not pushed onto the motherboard securely, I pushed it home and hey presto, wifi and Bluetooth now working, phew, Thanks for your help !

[Q] [q] tf101 hardware mods inside dock pictures!!!!!

Thread for hardware mods
POSTING INTERNAL tf101 pictures
like 3g dongle ? internal sd cards? ssd?
removing the battery for 2 HDD 500go?
finding sd cards hubs? usb to sata cables?
? there is a place in the tablet for a 3g dongle?
there are 2 screws under the upper rubbers and the dock open easy
there is a lot of spaces avaible
My MIFI might actually fit in there, all I would need to do is supply it power somehow.
I'm no hardware engineer though, but if thats possible it would save you from the driver issues with a 3g dongle.
I wonder if it would be possible to check which pins from the adapter connect to USB - so we can make DIY USB adapter for those without a dock.
hmm adding an hdd would be very interesting, sata won't be very hard, powersupply will be.
Sent from my O2x with CM7
This is what I was looking for, looking to do some mods to the dock.
Thanks Markolino72.
Internally mount and wire a 32gb memory stick to the USB port so you get a 32gb hard drive added whenever you dock It might even have enough room for a portable USB hub so you don't lose use of the external usb port?
does anybody think it will be easy to make a DIY dock fix for those with battery draining issues like me?
It seems like it would be relatively easy - just make a switch to either connect or disconnect the cords coming from the docking point.
Or even better, maybe if you put the correct microcontroller in there you can have it switch the pins to floating, if it senses that there is no tablet connected (not sure about the details though)...

Have you seen the post in the General forum (2nd page now I think)? Posted by Asus_USA themselves, if you prove the 6 steps that your dock has the issue you can get a new one! I really do hope that I can get mine exchanged, waiting on a reply from my local service center..
Regards.
In regards to the hardware mods, that really looks amazing. Would love to put in my mifi there as well, attach it via USB to charge = your own 3g model Maybe a little modding you could get the mifi to power on only when the dock is connected (remove the battery of the mifi?) so that when it powers on it'll power on the mifi as well. Only a few thoughts.

it's a good thought but the mifi I have (novatel 2200) wont work without the battery, for some reason if the battery is bad or removed you cannot run usb, it must be the way they have the power run through the battery or charging. Not sure if all are like this or not.

I talked to the Asus service rep about it. They currently won't give you a new one since they have a hardware upgrade to fix it. If you wanted a new one you needed to do before they solved the problem. I'm waiting on the upgrade part to be delivered for for mine. Should in a few days.
A switch should theoretically work. The guy at the service center said the replace something that goes into the hinge of the dock. Looking at the teardown pics, you can see a wire goes into each side of the hinge, so I think they replace the wires and maybe make a new connection somewhere on the dock.
Surprising how much wasted space there seems to be in the dock -- it's nowhere near as tightly packaged as the tablet itself. Looks like Asus can optimize the size or fit some more features in future versions, if they want...
Let me see if I am thinking correctly...Your saying using something like mifi installed via USB wires (will it be always on?) then connect via WiFi on your transformer? So basically your putting the mifi in a case that can never be opened without a screwdriver? I guess one would always have access for your other devices as well as long as the TF is in the vicinity.
P.S. I think I think this is a good idea, not decided though. I like to think of it in a real world application.
there is another post with a guy putting in an SSD, but it bulges at the keyboard. A 32g SD card would be nice.

There's very little chance they'll give anybody the part, and nothing in the previous person's post suggested they're doing so for him.

Well I ended up calling them. I would have to ship the dock to "someone" in the US, have them ship it to the repair center, fix it, ship it back and then ask that "someone" to ship it back to me... sooo, I'm basically screwed... I ended up with a nice 150US paperweight (not even considering the horrible light bleed on the transformer).

Yeah, actually, I hadn't realized that but it does say it clearly on the product warranty page:
"Brazil and South American countries don’t support global service"
http://support.asus.com/warranty.aspx?SLanguage=en&p=20&s=16&m=Eee Pad Transformer TF101
took mine apart also and there is quite a bit of room.
i plan on putting a 128gb usb flash drive inside the dock and soldering onto the usb connections once i get all the bits in.
Any bigger pictures? Are the screws under the rubber feet?
just two screws under the rubber feet near the hinge then it just pulls apart from the top
had to take mine apart as the spring/clip mechanism for the sd card wouldnt lock the card in.
now the card is stuck in with no nails haha a simple fix.
This is good news. I hacked a Crystal HD decoder card (pcie), USB wifi dongle, a logitech nano receiver, and a 4 port micro usb hub (from a touch screen setup) into a Dell mini 9 and there was absolutely no room compared to this.
They even have covers for the USB ports, so if you remove a header and solder wires up you just have to hot glue / epoxy that cover from the back and you are money. Looks clean and stock.
I have an old 64 GB thumbdrive that might find a new home. Maybe a 1.8" usb HDD would fit in there with the battery, without the battery who knows.

[Q] Broken pin on USB Need Solder Location On Board

Hello , When I first Purchased my Evo 3D, I noticed that any usb cable attached to it would never fit snug it always had movement like wiggled alot. I should have exchanged it but didn;t think it would eventually lead to serious damage until now, well, somehow the first pin on the right broke off and checking online with research it apparently is the +5 of the usb. Which basically screwed me.
I don't have much of an issue with no longer having the usb data sync ability since I can just use a micro SD adapter, and I have an External Battery Charger from Radio shack which helps because I can just charge the batteries with that and insert in my evo3d But the issue I have now is I realize i rely on the 4G tethering ability which i use constantly and it has become a pain to have to run and switch over batteries so my wifi tethering can maintain my computers online.,
Anyway so noticed a few evo 4g mods online where the person would solder two wires one to the negative and other to the 5v positive where the usb is located and then shape the wires nicely and make a custom usb hole somewhere else on the phone and eventually have a usb charging ability similar to one of the attached pictures ( for evo 4g of course not for the 3d)
So anyway i would like to try something similar where i can just locate some solid solder points on the phone and wire up two 5v and ground wires and relocate a custom usb slot somewhere else on the phone, Below is also some zoom closeups of the evo 3d board so my question is any advice to where I can solder the 5v and ground to, I am clueless to where and what points i should try the underside of the usb slot is all metal so seems like not able to solder there maybe on one of the little chips or something perhaps
,, thanks for any help
in reference to the attached images:
the one with the 5v writing is for an Evo 4g Not 3d But Im putting this picture i found online just to give a similar idea of what i need to find on the 3d
the one with the wired shell mod us just Another photo online of what I want to do but once again need the solder points
the other two are the best closeup pictures I could find of the 3d which maybe someone can just point out to me the locations by looking at it, I will take clear zoomed in photos if needed when I have access to a camera at home
thanks anyone for your help!
Why don't you just take it to Sprint and have them repair it? They'll do it for free.
Not from I heard. They charge 100 to fix it. And not even sure they would give me a loaner phone in the meantime. Also , I went into RADIOSHACK and showed and.spoke to one of the reps and he.told me.I wouldhave to pay unless I had their extended warrantee.. I noticed a resistor like chip above.and in front of where the 5v pin is.I wonder if I can solder on that

Call sprint and talk to a supervisor. They will send you a new phone or set up repair for free. Call and hang up twice, then call again to get sent directly to a supervisor.
Unfortunately me being a tinkerer ended up breaking off the ground pin and was not able to get serviced , even tried the supervisor and no go, I tried another radioshack and sprint store and of course they noticed it was opened so screwed me out...
anyway,, I taken some fair quality images of the board surface. maybe a +5v location can be pointed out from the images? thanks again

Instead of making a new thread, I figured I would add to this... I too am trying to mod mine with inductive charging, unfortunately my hands are a little too shaky to solder to the point that I discovered to be continuous with the +5v on the usb port.
I can't really find a clear picture of the PCB anywhere otherwise I would show you, but its about a centimeter or two down from the top left when you open your phone, run your multimeter through those points and you'll find it.
I guess I came here looking for another point..

Hmm thanks. I will try it when I open the phone. The soldering point should be bigger than the micro-usb pin I would hope.

[Q] Need help on how to dismantle Archos G9 80 16GB

I have G9 80 16GB Turbo. The plastic part of the inner micro USB feeder is broken and sticked out to the USB charger pin. My USB charger cable now blocked by that thing and cannot be use anymore. Now in the USB feeder of Archos just remain 4 tiny metals without plastic support (only 4 USB metal pins connector) and not able to take charge by anyway, it is bricked because of no battery power.
It is just 2 months old and no warranty since I bought it in airport transit. 3 times emailed [email protected] with no response as the world has suspected.
1. I've checked my Archos and did not find any screw other than single screw in the USB 3G compartment. I really thankful if anyone can write step-by step dismantle procedure.
2. Can anyone share the shape of USB type soldered to the PCB to enable me order the part and soldering it alone.
3. I've search this on thread : http://forum.xda-developers.com/showthread.php?t=1557506, but the information provided on how to dismantle is not very clear.
4. Thankyou in advance.

1. I've checked my Archos and did not find any screw other than single screw in the USB 3G compartment. I really thankful if anyone can write step-by step dismantle procedure.

There's only a single screw at the back.
The housing is hold together by some plastic clamps and it is a pain to open the case (at least compared to a A101IT Gen8).
You really need some force and be very careful not to damage anything...
I'll post a few pics this week in a different thread, because i opened the device last week and it was little bit catchy

Usually this is not an easy task... at least for the unexperienced ones.
Be careful with the thin lines on that PCB.
To unsolder the connector you'll need a lot of heat because it is connected to the gorund plane of the mainboard.
Anyway i don't know the manufacturer, but i guess these MicroUSB connectors are all pretty similar.
So try to catch one, wherever it is sold.

You should start on the opposite side of the connectors and use some plectrums (used by guitar players) to lift off the plastic clamps.
As i said i'll prepare some pics...
EDIT: Here's an overview on how i opened the case.
As already stated it was a pain, and though i had been very careful, some tiny plastics got damaged.
The red circles mark the plastic clamps and the holes they were stucked in respectively.
The green arrows mark the direction i slided my guitar plectrum.
In between you'll have to use something like a screwdriver or putty knife to lift the clamps from their counterparts (this was the evil part).
In the end lift the top of the housing in the yellow direction.
Please take care of the flat cables of the TFT display, don't rip it off!!!

scholbert,
I don't know how should I thanks for your detailed information and photo on your reply.
Below my comment:
1. There is no abuse on the USB port (even no single scratch or dent to prove the abuse, from new I feel it is really tight when I connect the cable into the port, finally the plastic part comes out "cleanly" along with the USB cable connector when I unplug. That's way I try to bet the warranty honor...ray.
2. I've checked eBay and I find many type of micro USB port selling.
3. Based on the generous help you've written I will try to dismantle my Archos when I have spare time within this week.
4. If I may ask, for what purpose you dismantle your Archos. And did you find any problem something like not properly tight when you remantle it again?.
5. From the picture, are all the clamps just on the display side, or mix up and down between the base and display?. Appreciate if you can post the zoom picture of the clamp and the hole to know it's anatomy to make easier when pushing during dismantle process. I also seeing 4 screw-like holes on 4 corner, are they also something like alignment clamps without actual screw?.
6. Big thankyou again for your response.

I don't know if i got a second edition device, but i realized this screen issue as well (pressure on the back causes effects on the display).
So i thought i may open it and try to solve this issue.
Anyway i always like to investigate on the construction of these devices...

To be exact, the clamps are located all on the base unit.
The display side got the holes for the clamps. I'll see if i could make a more detailed picture, to point you in the right direction.
Though i'm not sure if it helps.
The srew like holes you pointed at are for alignment only.
I also found some glue in the holes, but this is no problem.
Some words on seperation...
It worked out like this on the long side of the housing (upper and lower):
- I tried to seperate the display part and the base with the plectrum step by step
- tried to locate each clamp step by step
- then used a screwdriver
- tried to press gently against the clamp, direction outside to inside
(be very careful and the long side at the bottom, because of the display flex cable)
- then try to lift the parts more and more (it's terrible, but it works)
- keep an eye on the torsion of the display side
(seperate the parts too much, might crack the screen)
I guess i'll prepare some more pics...
Stay tuned!

You are really a man god sent to me, thankyou so much. I'm really itching to do the job. First thing I will do once dismantle completed, is to wire two lines for temporary charging until the part I order arrive. If by any chance impossible to replace micro USB port, then I will make hole on the base for common round type DC charging port + and - only.
Hey cangguek,
as promised, here are some detailed views of the clamps (base unit) and holders (display side).
The are four holders in total with two holes each.
The holders are seperate parts and are mounted with three screws in the display part of the housing. Each holder fits into two clamps of the base unit.
Unfortunately they can only get disassembled after you managed to open the housing.
The edge of the clamps point to the border of the base unit housing.
So you may try to push them gently to the inside to release the mating part at the display side.
Anyway i hope things are clear enough now...
Some words on your idea of soldering a DC charging port:
Electrically this would work i guess, but there might be some driver issue which could prevent the unit from charging.
It depends on how the charger is identified by the software driver, which activates the charging process.
On some devices it is required to shorten the data lines of the usb connector, others use the id pin on the micro usb to detect wether a host pc or a wall charger is connected. I don't know how things are done on the Archos 80 G9.
I just wanted to point that out before you start soldering...
Good luck!!!

-Data lines are not shorted, charging cable is a fully functional usb cable
-There must be something done to 4th (unused) pin in micro sd plug so device can detect Archos/"normal" cables (my guess- check data lines->if usb host not present check 4th pin->original=fast charge/3rd party=slow charge)

Yeah i know that the data lines in the cable are not shorted.
AFAIK, they get shorted when connected to the wall charger.
I own a Milestone phone (which definitely requires the lines shorted for charging) and i successfully used the Archos wall charger to charge this device.
At least i wanted to point in this direction...
Thanks for your comment.

Ok
-data lines are shorted together in charger (not to gnd/vcc)
-that's strange but 4th pin seems not to be connected anywhere
sorry, left empty.
Dear scholbert,
All the process as you said really a devil. I am stuck here (at red arrow) and can not proceed unless I tear it with force. Seems there different clamps ?.
Now I am stopping the the job waiting your further help.
Thankyou for helping me:

Yeah i know it hurts... but AFAIK all the clamps are identical.
Nevertheless i realized the same during disassembly.
Some of the clamps did release quite well, at some point i also was afraid i'll break the device into pieces. I'm sorry but i guess you'll have to use gentle force to get it seperated.
BTW, i don't want to be responsible if you damage something
Another warning at this point:
I even did break some small plastics during opening (in the mainboard area), but it doesn't matter in the end, because there are many clamps to hold the parts in place
Good luck!

Just to confirm the only screw I removed only the one under the stand stick, I hope I am not missing here. I am still not continuing dismantle process, but at least 40% of the casing has been opened.

Man..., wtf, bottom pin of micro-usb (for desoldering purpose) covered with external card slot...grrrrr,....
Please look at the usb pin inside the housing, only metal pins only remain, the plastic part were come-off sticked-out along with usb charger cable. Anyone would come with idea on how to trick my situation?. Removing external card-slot then removing micro USB port seems a big job to me. The solder were very-very tiny...
I have completely separated and disconnect the wires of my Archos, so I have two part now: the base and the display part.
Anyone asking specific picture parts of my Archos, I am ready to shoot.

I am happy to see these pictures as they confirm my suspicion. The usb charge port is only soldered on, no screws to hold it in place. That is not a proper mechanical construction and it is no winder it becomes disconnected with only a little use. I have sent 2 units back already which will no longer charge as the mount point has come loose. Number 3 broke too now and as they want me to pay for shipment again ( €50) I am thinking of fixing it myself in stead, but properly..
I have the same problem
Did you eventually repair this problem. If so were did you get the spare part. i have got the same problem. I think i might try returning to my supplier first.
Brilliant tips

USB C Port Not Charging, Recommendation for Replacement?

Hi All,
I have a Nokia 7.1 that stopped charging. I cleaned out the charge port and tried different cables and adapters but nothing worked. I've since come to find out that it's a common enough problem that lots of people post about it on Nokia's support forum with no other option other than taking it to a service center. I'm in the USA and there's not a single service center in my state so I decided to try and replace the daughter board myself. I've done this kind of thing before on other phones, my Nexus 4 was a frankenstein's monster by the time I was done with it.
My problem is I can't find a reliable source for a quality part. There's tons of replacements on amazon, ebay, aliexpress and other random sites but all the ones I've read had issues for connectivity of cell service or wifi. Does anyone know where I can source a new daughter board for this phone?
Any help is greatly appreciated.
Thanks!!
I went through the same issue.
Bought another type c charging port on Amazon, it still works.
Awesome! Thanks for the reply. Did you go with one of the ~$10 ones or one of the ~$20 ones?
My 7.1 developed the same problem. What is the root cause? Is it mechanical problem of the connector pins worn out/oxidized? It does seem to be a mechanical problem since I can still wiggle the cable to make it charge for a while. What puzzles me is that the USB-C has inherent redundancy with 4 power and 4 ground pins that it should not easily fail. I have a phone with the old micro-USB and the charging still works flawlessly.

I'm not sure. It does seem to be a mechanical problem, but I've seen some repair videos where they open it up and just run a soldering iron over the connector pins on the board and it starts working again. I've ordered a daughter board and a replacement back glass panel in case I break it trying to get it off. I'll update after I get the parts and open it up to see if it works.
The board I ordered was this one from Amazon Smile:
https://smile.amazon.com/gp/product/B08166DLDC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It seems like the ~$10 boards are missing some chips that the ~$20 ones have, at least according to the pictures that were uploaded with the listing.
@bpowdhar, Thanks for the quick reply. I did order a connector board on Ebay, and it looks to be of the ~$10 variety. I'll see how it works when it gets here. I will also try the "melting the solder" trick without removing the connector first. If that works, I'll leave the old board in place just to minimize the risk.
So I received the USB-C charging board and replaced the bad one. Now, it seems to be charging normally. It took some work to open the back cover by heating to soften the glue/tape around the edge. I then used an a xacto knife to pry the corner open followed by dragging an old credit card to slowly separate the cover. Once it's open, everything went smoothly. Just watch one of several Youtube video clips to know what to expect. You do need a small Philips screwdriver and a #5 Torx driver. You need to lift a ribbon cable and a micro coax cable from the board. Just don't forget to put them back on to the new board. I didn't bother to fix the old board by re-solder the connector pins because they are way too small for my solder iron.
I rely on the existing glue/tape to glue the cover back, but I'm sure it's not as water/dust proof as before, so I may redo that part to clean the old tape out and use the new tape or glue when I have more time.
I do noticed a couple of parts missing on my $9 board. I don't know if they have anything to do with regulating the high voltage fast charging. I usually charge the phone with a 5V adapter, and I will stick to 5V, at least for now.
Thanks for the update! I'm still waiting for my board to arrive from Amazon. It was delayed with the new shipping date anywhere from Nov 5 - Nov 10 and it still hasn't arrived. It sucks because tracking info shows that it arrived at my area's sorting facility on Oct 29 and left it on Nov 4. So it should have only taken a day or two to get to my local post office and to my house. I'll update when it finally gets here.
I know it's been a couple of months, but I finally got the part and swapped it out yesterday. The battery was completely dead so I plugged it in to charge and left for the day. I came back to it this morning and it's at 100% battery! I'm so happy now! I've attached a couple of pictures showing the old board (with the red dot) and the new one. So far no connectivity issues, but I'll give it a couple of weeks to see if anything changes.
A couple other notes:
It was surprisingly easy to get the back glass off. I used a heat gun on low and ran it around the perimeter for a couple of minutes and a utility knife to cut the adhesive. This part was what I was most apprehensive about tackling.
The fingerprint sensor comes off the same way, apply heat and press / pry away from the glass to reuse.
If I had to do it again, I'd buy the tube of sealant. The replacement glass came with a set of narrow adhesive strips and those were a pain to deal with.
Thanks to everyone who contributed to the thread. Hopefully this helps someone else.
