Digitizer driving me crazy

So I've replaced the digitizer on one of my thunderbolts and all was well. I had not really gotten the lcd affixed to the chassis correctly so after a few days the gap in the phone and the frame caused me to tear back into the phone. I got it all sticky taped down to the chassis and put the phone back together and now the phone is doing all sorts of crazy things. I did a format system, reflashed the rom, bamf forever 1.0.5 and the phone seemed to be fixed and now its right back to doing what it was. It seems to register touch when im not touching the device, also some times when i do touch it its a few inches off, making menu selections impossible and typing as well. I've gotten flustered with this phone beyond belief.
I also had a inc2 do the same thing a while back. Which has me thinking it may be something common. Possibly a dirty connection on the ribbon cable or something? Its getting too late to break into it again but I was wondering if anyone has had anything similar happen?

I've never torn into a phone, and I never intend to. My guess, if I had to make one, would be that the digitizer is somehow making contact with the body of the phone in some undesirable way, possibly through a slightly conductive tape. ANY sort of contact with a substance or object that could trigger a change in the screens static field will cause you problems.

I think its just the digitizer that's bad, it can't be anything else, just doesn't make sense... So, now who sells the absolute best digitizers?
I've bought fifty plus digizers from various people on eBay, I've used repair universe and can't recall ever having gotten a bad one. But who has the best?

Just googled it and quite a few threads on various android sites where people replaced digitizer and have all kinds of problems getting the touch to work properly afterwards on thunderbolt. Must not be an easy task on this phone.

So I took it apart... Here's how it went.

So a bought my tablet, without the dock. Being a modder/hacker/tweaker, I knew I had to root and learn the flash process specific to my device ASAP.
Horrified to find that I would lose my warranty, and that I would be on my own from that moment when I would have unlocked it an beyond.
So I hesitated... For a week... and unlocked, rooted, and flashed a couple ROMs. All is well.
Fast forward 4 months...
I started getting issues with the touch screen on my device. I was heartbroken. I knew that nobody would fix it, despite it being a hardware defect of some kind.
The issue I was having was the "Ghost Touches" which would swipe up and down rapidly and randomly on the left half of the screen.
It would happen seemingly at random, and progressively became so bad that I couldn't use my TF700 any longer.
Shelving it for a few weeks, I finally became inspired and motivated to try to fix it myself, or at least discover wtf was wrong with it.
I found that pressing on the bottom of the tablet (the sections that surround the screen itself) would actually make the problem go away, but also make half of my screen unresponsive until I screen locked/unlocked it.
That made me feel that it was software related seeing that a simple lock/unlock via the top left button would make it stop for a few seconds, but this wasn't the case despite this glaring fact.
So I knew I had to open it, and I had no resources, couldn't find any videos, no information on opening this thing was available, at least at the time.
The steps I took were:
1) Turning off the device of course.
2) Flipped it over and with a flashlight looked down into the two slots for mounting it on the dock.
2a) I peeled away the squishy stickery thingy from each slot.
2b) There are little circles, one in each, that using something sturdy, you must slide to the tablet's left. (I used a nail...)
3) Using some kind of plastic yet sturdy wedge, you must unsnap all of the clasps under the screen to free it.
3a) I used a guitar pick, starting from one of the slots on the bottom, I ran the pick around the edges of the screen after carefully forcing it between the aluminium case and the glass.
3b) With somewhat violent prying motions I was able to free all of the snaps. (You need not unsnap the top side, only the bottom, left, and right sides. If I recall correctly)
4) There's 2 ribbons, they're sneaky, one is copper colored, the other is white. The white one is the scary one.
I turned on my tablet at this point, everything worked fine, I was VERY thankful at that point.
Now I looked around on the inside of the device and noticed that the point where the copper ribbon meets the digitizer/lcd screen was dented a bit, and when I ran my finger across it, the phantom touch problem went absolutely crazy. Bingo.
I found the pressing the ribbon flat against the screen, and firmly holding it in place fixed the problem.
So with a piece of tape I found next to me, I carefully rolled the tape over the dented area of the ribbon, and firmly secured the ribbon to the back of the screen preventing it from moving at all.
Upon reassembling my device, all has worked well, though when I shake the tablet, or press on certain points (takes a fair bit of pressure, nothing you'd ever do intentionally) the "Ghost Touch" comes back, but is easily remedied by a quick lock/unlock. This happens only once or twice a week at best, and I use this tablet HEAVILY.
Sorry for the messy post, and the lack of pictures, I didn't take any, and am not doing this again until I have to.
I really hope anyone who read this can gain from it.
Regards,
~HNx

That is some good info there.
Thanks for taking the time to put that together. I'm sure this will be very useful/helpful to those with similar/same symptoms.
Good job on doing it on your own like that. :thumbup:

Wow thank you for the post very very much.
I have had the ghost touch problem ever since the start, but it only came about with the dock connected. Through trial and error i figured that the dock is pressing on the bottom of the screen when you open/close it and causes persistent ghost touch. Simple on/off screen would fix it until i adjust the dock angle again. Never had it without dock connected.
Mine is also unlocked so no warranty. Although i am planning to rma the dock as its started to make clicking noises when open/closes.
Will definitely do your fix soon. How long would you say the whole process took you the first time?
Any idea what is causing the ghosting after the fix? My thought is that it was the gorilla glass bending that was creating some interference inside of it, hope i'm wrong.
Also, since we are on the fixing it from the inside page, the clicking noises (i get slight ones if i press/squeeze by audio jack), could they be fixed with some filing. ?
And the big one, could we solder on / replace the inner sdcard chip? perhaps hack a flash/ssd in there if possible?

There are pictures of the TF700's internal components on the iFixIt web site.
I don't think you can replace a BGA chip without damaging the board.

Took me a while to get to it but i opened her up today.
Firstly i recently received my dock back from RMA because the left top corner kept opening up when i tilt the tablet and i had to press on dock to click it back together. RMA people sent it back saying "works as intended, no problems found" with an added touch of removing right side rubber protector (left and bottom still there). Thank you for that..
So i decided to take matter in my own hands and lifted the top left rubber foothold of the dock only to find the warranty "void" screw just fall out... apparently it was never screwed in. OK easy fix, touch of screwdriver and dock is now better than new. Nice quality control there ASUS.
So now excited with first fix, i got to the tablet.
The ghost touch has been plaguing me with the dock attached every time.
I had tf700 unlocked to get the extra performance due to slow flash so no warranty.
Used 2 guitar picks, managed to get the screen off no problems. Tested if it still works, fine there too.
As noted by OP, the orange ribbon causes ghost touches as you press on it.
The white ribbon was in the way so I unplugged it from the screen.
This is the trouble causing area:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
It was obviously insecurely connected to the touch screen. I tried to stuff some tinfoil to the edges to hold in better, however, upon testing my solution, had a fatal (to the screen) accident.
The white ribbon killed lcd power and I couldnt tell if device was on (which it was). Upon attempting to connect the ribbon back, some contacts touch other contacts on the connector, small electrical flash, and lcd screen is dead... :crying:
tablet still works with dock and hdmi out:
Well since screen was broken already i decided to remove it from the touch glass to further investigate the ghost touch.
This is the problem, the orange ribbon was just glued to the touch screen (pressed between 2 screens) and has no secure connection hold. perhaps the glue unglued or air bubbles get in the way or the 2 screens not hold it tightly enough. It is obviously a design fault.
Whoever decided to use this method and then use same badly secured connection area to apply force to keyboard dock to open/close the device, did poor job...
Sure it is my fault i ruined the screen but i cant help but to feel cheated from ASUS.
I loved the idea of transformer tablet and was a very loyal ASUS fan. Bought it first month it came out, used for a year already.
They advertized a premium top of the line product, use a cheap memory solution which makes customers unlock and
void warranty. And when design failures arise, well, you are on your own.
Every TF700 tablet has this "ghost touch" problem, by design. Some may be better than others. It is just a failed product execution.
Not sure what i will do with the tablet now, have mixed feelings about it.
But as a long time ASUS customer / fan, can no longer recommend their products. Their new "direction" of passing bad designs as premium products, just not what I expected.

upon further review, the lcd connection wire had some pins burned out from the short, so hopefully lcd screen is alive.
[EDIT]
WOW they sell from china for 45 dollars!! for a tiny piece of wire like that...
anyone with a broken/replacement lcd which has a working wire be willing to salvage/sell theirs?

Just as an update, I've yet to need to take my TF700 apart again. The "Ghost Touch" problem hasactually gone away entirely even with
pressure applied to the effected areas.
Further I've tracked the problem down to the tablet getting hot, very hot. As dankens points out, the glue is all that holds the ribbon in place. It's my suspicion that the glue becomes loose. The ribbon most likely shifts a bit at this point, and the problem arises.
Be careful tf700 owners, once it starts, it doesn't just go away.

First I'd like to apologize if my post played any role in the eventual damaging of your tablet.
I hate to see such an expensive device broken.
You said it was just some burnt out pins that are problem. I'm pretty sure that I could repair it if you havn't yet bought a new screen.
If you're interested, you can drop me an email -- [email protected]

Well, i went out and got the parts from china/ebay, i think they ship them on wales from china because it took forever!
Started off with the damn white ribbon which cost me $41 for a 4 inch piece of wire!!
LCD was still dead, so i figured it got fried as well. new LCD (no digitizer) cost another $88. After assembling (now i make sure the battery is unplugged first thing, and connected last) i could see the lcd lamp turn on but screen was black.
Next to go was the mobo (i think GPU fried as well), they dont really sell those much, cheapest one was $80 (refurbished).
connected all and viola, back to normal. cost of parts: 209, worth it? not sure.
Definitely a learning experience, damn parts cost more than the tablet itself.
Looking forward to Dell Venue 11 pro (i5 version).

For those of you who will attempt to fix the same problem reported in the OP, my 2 cents:
1. After you successfully open the tab, but BEFORE doing anything, turn off the switch in the area circled red in the attached thumbs. This will cut off all electrical current to the components and prevent accidental shorts. It's called "service switch" for that reason;
2. The information given earlier about how the ribbon was bonded to the glass was incorrect. So I deleted that part. I examined under a microscope and it appeared a chemical strip of some kind was applied to the glass for bonding. Apparently, it worked in my case since I put a piece of kapton tape where the ribbon came off the glass, More likely, it was a part of the ribbon that had no function in the operation of the touchscreen. Thus, there ain't no way one can re-bond it once the ribbon's ripped off the glass, undamaged though it might be.

It looks like I'm having the same issue, but I'm confused about where to put the tape. Should I be removing the digitizer for this? Does the tape go RIGHT WHERE the ribbon connects to the glass? Or do I simply fold the ribbon over top of the computer chips on the back of the digitizer and do it there and tape it there?

I hope someone can answer this. I can't figure out where to put the tape from all these posts either. I am about to embark on this journey. I have never disassembled a tablet or smartphone before. I am not that scared because I haven't really used this tablet due to all the problems I have had with it and have moved on the the Nexus 7. I would like to have it back in service though since now it is unusable due to the ghost touches.
Edit:
This might be the info I was looking for from a post above. Thanks.

I successfully opened it up and taped the white and gold wires down but the problem didnt go away. I am able to reproduce it more now though. I didnt tape the gold wire to the edge of the screen because when I pressed on that with the unit on it didn't cause the issue. I was able to make it happen while opened by touching the gold wire near where the problem spot seems to be but not on it.
Wondering if I build up a protective bump of material like tape inside so the case cant be compressed to cause the issue if that will help. I refuse to send it anywhere or purchase parts. I've spent too much time and effort on this thing. Really sucks to have a tablet that I cant use. I guess I could sell it on ebay for parts.

I'm going to keep bumping this as I discover more.
So I took it apart again trying to rig it up to work.
I found that the gold cable doesn't like being bent the way it is bent from the factory. If you straighten it out and fiddle with it, the ghost touches go away. I have been doing all my testing with the tablet powered on making sure not to disconnect anything. This way I can really get a feel for what is causing the ghost touches. If you intend on doing this look for the service switch and shut it off. Its hard to find even though its right in the middle of everything.
Cable with "33" written on it is the issue. I cut away some of the black plastic they used to keep things neat.
Pulling away the problem cable for your viewing pleasure
Tried to add some foam padding which helped with the case open.
Too much padding to close the case. Might try again with less padding.

[Q] Broken touchscreen, wacky random digitizer.

I'm sad to say I finally destroyed my TF300. It fell from about 6 feet onto tile. The screen is cracked in quite a few places, but luckily it didn't spiderweb. The touchscreen kind of works, I say kind of, because it's touching in random places all over the screen. So my question is, can I possibly unplug the digitizer only since the LCD works fine? That way I can use the keyboard dock's mouse or a USB mouse and still use the device. Thanks in advance for any help.

this happened to me as well. On youtube there are many tutorials of how to replace the screen..
they will show you how to take the back casing off
then you can just unplug the digitizer cable (its the yellow cable with two connections on the bottom right of the back of the tablet) this will disable the touch but if you go that far you might as well replace the whole screen you can get online for $50.
and make sure to take note of the digitizer revision number as asus makes 4 different types and only the one will work on your tablet when you want to fix it...its a number on the digitizer cable either g01 g02 g03 or one other i cant remember off the top of my head

Sorry, I meant that I didn't want to fix the display, just disable the digitizer so that I can continue to use the device via HDMI. If I unplug the digitizer, will the LCD still work?

After unplugging the ribbon cable for the digitizer, most of the random touches have stopped. But now, even using the built in touchpad or a USB mouse, touches do not hold and can cause random presses to occur in various parts of the screen. Any ideas?

I'm not sure but could be a different problem? I've done the same to mine and my keyboard dock works just fine

Spontaneous presses? This is at random, some tabs have it, others don't. That ain't from the keyboard; rather from either the digitizer, though detached it might be, or the TS board, or both in close proximity with one another. I've experienced this and still have no idea why. I've had perfectly good dig and TS Board do it when the board is left dangling and not screwed down to the magnesium frame. The only way to stop is to replace the digitizer. Or you can try to yank the dig's ribbons off the glass, as I've noticed ghost touches produced by a dig with partially torn ribbons (on the glass side) that were still connected to the PCB. The dig is not repairable anyways. You're risking nothing.

Not sure where to start. If you've taken apart the thing before, i'd be easier. Remove the back. Turn off the service switch (Important). Otherwise, you might burn a coil on the motherboard. If you don't know what that is, look at the top of the motherboard. To the left of the power switch (thin amber ribbon for power on top side and volume on right side), there's a switch mounted on the other side but accessible from the top of the board. You'll see the printing "off" and "on" on this side. Slide it to "off" position. (Thumb attached shows location of switch at top, and where the ribbons should be cut off at bottom).
The ribbon part that's taped to the glass is hidden under the lcd. If you don't care, just snip it off where it meets the lcd edge. There's really no need to remove the lcd if you're not intent on replacing the digitizer. Again, since I am not certain what caused the ghost touches in your cases, it's possible they will continue. Hopefully, they won't. But at this point, the digitizer serves no function other than protecting the lcd surface on the outside. No need to save the ribbons.
To tell you the truth, I've tried using the tab with a dock and no touchscreen. You can live with it, but it's enormous inconvenience any way you use the device, from recoveries to roms to any app within. It's just not designed to be user-friendly that way. I eventually gave up and replaced the digitizer. You can find one for around $35.00 these days.

Thank you very much for the information.
I don't plan on using it as a daily device, I just picked up my Note 3 the other day, and using the TF300 is going to feel like going back to the stone age. I really just wanted it to have basic functionality, because I still have the HDMI cable for it, and have XBMC and VLC installed on it, so I can play videos easily on my TV. It has Cyanogenmod on it right now, so really, it should be fine for a while. I could probably also hook up my dualshock 3 to it and game on a TV. Portable low-end console. I'll update the thread later if whenever I get around to cutting the ribbon cable. Thanks again.

Touch screen help

How do you diagnose what to replace on your tablet? Is it possible with the tf700t?
Here is the scenario- I travel a lot and kind of pack my backpack tight and I think the extra pressure on the tablet has screwed the right side.. I turned on show touches in developer tools and a touch comes and goes from the right mid side (sometimes it moves) .
I was able tdeal with this for a while but now after my last travel it's made it almost impossible to use the tab. My tablet it is out of warranty, unlocked and rooted so don't know if I could sent it to Asus for repair.
My question is, is it my touchscreen I need to replace or is it another component? Currently I I hold the tablet and apply pressure on the right side (back) I can make the touch go and come. If I turn the screen off it will remove the touch for a bit. if the touch won't go away I try to apply pressure to the back in various spots to it goes away

My understanding is if you can see what's on the screen the display panel is good. If there are touch problems then you MIGHT need a new digitizer. It could also be that in bumping it around and what not that the ribbon cable connecting the digitizer has come loose. Heat sometimes seems to be involved in this happening too. There are a couple threads here about these issues, fixing them and how to go about replacing the digitizer yourself and where people have bought them. It's not a feat for the faint of heart but it can be done at home.

Thanks I'll check it out didn't know if it was the touch screen or digitizer. I'm typing on it right now so seems like touch is just fine.
I suppose I'll open it up and see if a cable is loose. But do you think Asus would accept it for repairs? It's unlocked and rooted.

They woud gladly accept it for repairs... but they would charge you a bundle. Your warranty is void since you unlocked.

Touch screen/digitzer I believe are one in the same.
Sure Asus will fix it. In/out of warranty. But as mentioned, they'll charge you big bucks. My guess to replace the digitizer would be about 300USD. MIGHT be a little less.
If you open it somewhere inside, can't recall position, there is a service switch you should turn off 1st, before you do anything else. That might keep you from frying some component should a short develop somehow. Just remember to turn it back on last before you finish inside.
I recall reading that the ribbon cable is held in place by either glue or double sided tape and the heat aids in its becoming loose and can be part of the problem with the digitizer getting all crazy.
BTW Anyone can feel free to correct or add to this....

[Q] Erratic touch screen behavior when docked

My TF700 has recently developed erratic touch and screen behavior when docked.
Symptoms: Jumping screen - the image at times bounces around slightly
Phantom touches happen when touching the sceen OR the BACK of the tablet, and less frequently, when not touching the screen, but when holding the tablet where the screen angle may be moving slightly back and forth.
Sometimes, as well, the tablet does not respond to the keyboard. Changing the angle will sometimes remedy that.
It appears that this only happens when docked and may have to do with movement of the angle of the tablet in the dock. The problem seems to go away if I move the tablet/dock angle more vertical AND support it in the back to keep it from moving back and forth.
My unit is too old to be in warranty. At one point one of the plastic clips on the connector broke and I used epoxy to fix it. I also noticed that at one point, pushing the tablet back to too oblique an angle would actually cause the case of the dock to separate slightly.
It might be possible that some of the "phantom" touches that have been reported when a tablet is sitting untouched are due to vibrations in the room (walking etc) causing the tablet to move the docking angle sufficiently, resulting in the issues here.
Any ideas on how to steady the dock/tablet connection?

sounds more like your touch screen is failing, your fault desciption sounds just like mine did before I changed the touch screen and the issue has now gone away

Update- Found a "fix" for now
EDIT: I ended up using self-stick velcro, just the fuzzy side. I put a 2 inch strip behind each hinge. The fit is quite tight, but that is what I was aiming for. Tablet is behaving OK.
I tried using my son's keyboard dock and the problem did no occur. It had considerably less play in it as well. I have temporarily concocted a fix -- I put a strip of material (a thin velcro tie wrap, because it was handy) along the inside back of the dock hinge before inserting the tablet. This tightened the connection sufficiently to keep the strange behavior from happening. Gotta come up with something a little more permanent, though. I'm thinking of trying label tape (like TZe Label Tape) until the thickness is right.
