[Q] Replacing the Digitizer - Atrix 4G Q&A, Help & Troubleshooting

I recently had 2 dead lines going down my screen. From searching around I found that I needed to replace the front screen digitizer.
So I got a new digitizer, tore down the phone and followed the steps from a few youtube videos pretty meticulously. I reassembled the phone, and it powers up just fine. But it now response to no touch. I'm going to do a complete tear down again, but is there any tips that can be given? I've checked if the digitizer's ribbon cable is snapped in, all the motherboard cables are also snapped in.
Is there something I should check to see if it's just the new digitizer is a dud? Since the whole phone powers up and functions fine.. to me that sends up red flags.
Oh and I followed this video:
http://www.youtube.com/watch?v=TbR56jSplRs

If nothing else works you probably tore the ribbon cable, which is very easy to do. Also make sure you got an OEM screen. There are cheaper reproductions that aren't nearly as good. (Feel, glass, and details) the one I bought on amazon (from seller1on1 I think) is oem. Contact your company if you can't get it fixed, the company I got it from sent me like 3 replacements before I realized I forgot to remove the plastic bar.

avoid the "oem" digitizers and go for the refurb with bezel as these are also much easier to fit.
Have put 2 on now. One to replace dead zones and one when I dropped and cracked the screen.

Thanks, I did get an OEM one. I'll contact them to have them ship me a new one!
And by tore ribbon cable you mean the one attached to the digitizer? That had to be snapped onto the top next to the power button?

Yes, that one. The problem is the end attached to the digitizer itself. Never had to dig into this myself (knock on wood), but they say the part where the cable is attached to the digitizer is very very fragile and tears of easily (sometimes even micro-tears, something you can't even see, but it still disrupts the connection). They also say that cable is ridiculously short and that is a part of the problem why it tears so easily.

Some help for a newbie... [broken screen]

First of I would like to say thanks to this forum.
I try not to post any problems that have already been answered and this forum was a big help in getting my xda unlocked.
However I had only had my phone in working condition for 2 weeks, enough time to start to like it, when it fell and cracked.
I ordered a new glass screen (no bleeding ink) and had it overnighted. I sucessfully swapped out the broken scree, but in the process I screwed up the phone. So here is whats going on with it, if anyone can help me out it would be awesome.
When taking it apart I accidently broke 2 of the connectors for the ribbon cables on the back of the pcb. Now the phone wont turn on. The screen comes up but its just white and I cant tell if the os is loading.
Sorry for the long winded post
Thanks for the help
Chris
Also if this cant be fixed whats my best option, selling it broken or parting it out? How much could i get?

Well, I guess it depends on how broken the connectors are, but this definitely doesn't sound good...
If you post a few close-up pictures, I'll tell you if there's any hope for fixing it.
Well..
One of those 3 connectors lead to the screen.
My wild guess would be that it's not porperly connected since it's borken.
In that case, I would have done one of two things:
1. Buy a connector through an electronics component vendor, then ,manually replace the broken one or have a electronics lab do it for me.
2. Solder the wires to the connector's base manually (or in a lab) to over-ride it. (I hope you understand what I mean).
At any case, my guess would be a broken connection somewhere in the connectors (one of the 3). This can probably be fixed that way or another.
BTW - I have a lot of dust between the glass and the screen. How do you remove the glass from the screen (it seems to be attached firmly somehow)??
To take the glass apart from the lcd, there are 4 metal tabs (2 at the top and 2 on the bottom) you can pry a thin flat-head screwdriver between the metal tabs (you will see what I am talking about, when you look closer). It will sound bad but its just the glue coming apart.
I tried to get the connectors but had no luck finding a match.
So I am going to part out the phone.
Ill be posting the ebay auctions for the lcd screen, the new glass piece, the motherboard, the battery/case and whatever misc accesories I have lying around.
Before I put all the parts on ebay, I figured I would give the people on here a crack at it. I will entertain all reasonable offers. Send me a PM.
Here is what I have for sale
Case in good condition w/ battery
Motherboard - in good condition just missing the two plastic pieces where the lcd connects.
Brand new glass touchscreen/digitizer
Lcd Screen
Also for sale the in-wall charger, the sync cradle with an extra 3 stylus (styli?).

[Q] Guide on Replacing the Digitizer

Hi there,
I searched before posting this, but couldn't find anything for the Atrix...
Just wondering if anyone has seen/made a guide to replace the Glass/digitizer for the Motorola Atrix?
As to why I'm asking:
(If the image links don't work, you can find them as attachments to this post)
I've damaged the plastic around the glass (basically the housing, near the usb port) but I need to remove it from the digitizer...
I bought this: http://forum.xda-developers.com/attachment.php?attachmentid=572442&stc=1&d=1303199913
But as the ifixit teardown guide shows...
(http://forum.xda-developers.com/attachment.php?attachmentid=572441&stc=1&d=1303199913),
...When you take the phone apart, the glass is one with the housing.. Has anyone done this replacement of the digitizer or housing, if so, can you offer any suggestions, and what you used as adhesive to reattach the digitizer?
I've repaired the iPhone 3Gs and iPhone 4 before, both ranking higher in difficulty on ifixit's site, so I'm guessing the ATRIX should be a lot easier...
Anyways, any helpful tips or any guides would be greatly appreciated. I've already checked Google but no luck...

Try this http://www.ifixit.com/Teardown/Motorola-Atrix-4G-Teardown/4964/1
Or, this http://www.youtube.com/watch?v=TbR56jSplRs
Broke my digitizer and did the job myself using the youtube guide above. Just used straight up superglue to glue digitizer to frame. I put a bunch on the top and bottom and very little on the sides.
Amazingly the phone worked when i put it back together... for a while until I screwed up one of the ribbons by opening it a bunch more times. Be extra careful with these, especially the volume/camera ribbon. You can bend it pretty easily trying to slide it back into its slot.
Good luck.
NB: Theres places that will do it for as little as $90 in case you don't want to take the risk.

Thanks for posting the youtube link. I can't even quote the post because it involves an external link. The video was vague on details and the quality is crap but it did the trick.
My Arix got under the tires of a car (please dont ask how ) and only the digitizer broke, then i replace it with an OEM digitizer from amazon and now the proximity sensor is malfunctioning (Turns off the screen when im not near it or doesnt turns off when im near it), and there is a line of the screen that doesn't respond to tact. could it be the digitizer that came defective, or maybe it was the installation? oh, the other digitizer was broken and all but the light sensor was working fine and also the other thing. Sorry for my bad grammar.

I replaced my digitizer, and had the EXACT same thing happen (not the light sensor but the line in the screen that doesnt respond to touch).
Get a new digitizer, but get it from someone else.
That's what i feared, did you changed it back again afther that, and did it worked? and thanks.

No. I sold it and let someone else deal with it. Didn't have the time to replace the digitizer again. Too much of a hassle.
I just replaced a digitizer on an atrix... i didnt put any adhesive on it because there was what i thought was adhesive strips on the digitizer... but there's strips on the screen that doesnt respond, i heated it n tried reattaching the digitizer a few times n sometimes the home and back button will work, sometimes they wont... any suggestions? could the lack of adhesive cause this?
Menu buttons problem
if menu buttons is freeze till I block and then unblock my phone is it digitizer problem ?
what do you mean by " block/unblock" ?

Go the ifixit route!
Just went through 3 digitizers in my repair, and wanted to share my experience/caveats
I bought one digitizer from All4Cellular for $25, and the others with a 20% discount a few days later, for $20.
I installed
the first using the RepairUniverse Youtube 'how-to' method, and had a heck of a time threading the flex cables through the slot. Bent/twisted it too much, and nothing responded on the touchscreen, so I read some forum posts on how fragile they were, and regarded that as user error.
Got the idea to move the LCD screen from another RepairUniverse YouTube video and a previous post here, and tried installing the digitizer from the front face of the phone. It was still a delicate matter to bend the flex cable so that it fit through the slot, and then re-position the LCD and align the sticky strips of the digitizer on the LCD and casing. Part of the digitizer worked this time - a 1cm vertical strip on the left fowled any attempt to touch icons or use a keyboard, so I thought I had damaged things again (doh!).
Hoping third time was the charm, I completely disassembled the phone using the guide in the 'ifixit' link, since a digitizer/case assembly was suggested in another thread. The rear camera just needs to be raised above the casing so the thin plate can move upward, and the LCD pops out easily if the sides of the casing are delicately pulled. The digitizer can be positioned easily and with minimal bending/twisting of the flex cables.
When reconnecting everything the third time, I noticed that pressing down on the front camera / digitizer connection *with the rubber boot in place* didn't pass when pulling the connected assembly upward. So I pulled the rubber boot out of the way and snapped the camera / digitizer connection firmly, then re-inserted the boot. A loose connection might have been the culprit for the nonfunctioning part of the digitizer in the second test.
@MrSaba - I had the same issue with capacitive buttons - perhaps because the screen senses touch and disables those buttons. Replacing the digitizer solved the issue
trouble
Hello friends,
Here's my story - broke a screen, as usual slipped from my pocket. though broken, digitizer worked fine. after replacement with new one (digitizer only) - no luck it didn't work. bought a new one, this time with a plastic part around it to avoid damage to it's cable. after careful repair no luck once again - does not work at all. downloaded a testing app (i was able to remote control the phone with a piece of soft called androidscreencast), everything is ok, except digitizer. checked and rechecked all ribbons and connectors 10 times, nothing seems to be broken or twisted.
what's your opinion, is it worth buying third one ? what part of my repair went wrong ?
thanks

Not all digitizers are created equal. The ones that ship with the red stripe on the backing are junk. Spend more money and yes buying with a frame is key. Did you try reinstalling the original screen or did that ship sail already?

The first one was with the red stripe indeed, from china. The one with a frame came from UK, "used but tested OK". original screen is gone - tore off flex cable while removing.
Well, update...
2 screens bought on eBay were BAD. Had to wait full month for authorised motorola service to change the digitizer. Must say though that both merchants on ebay refunded, no questions asked. Lessons learned - pay more, wait longer, never give up

What I noticed on their video was that their folded digitizer connector magically unseats itself during the disassembly transition. I had to pry mine off based purely on guesswork and think I might have broken the flip-chip that is stuck onto the frame with double-sided tape. Like yours, my touchscreen doesn't respond at all, despite there being no cable tears. I'm going to try and re-heat that flip chip and maybe get the connections to work again (doubtful).
To anyone else out there attempting this... when you go to remove the touchscreen, HEAT THE CONNECTOR so that you can gently pry it out!
Bad screen I got 3 before it worked its fine now if old one partially works new one doesn't screen is junk took mine apart several times to figure out screens were junk...guess they felt sorry for me give me my money back plus free working screen.from amazon
Also that lock clamp u mentioned first video I watched didn't show unlocking that I just pulled it out and pushed back in it was the 2 screen that I figured out it needed to be pryed loose by the white clamp but guess I didn't damage it..

I have just put in my second digitiser. The first was one had a red stripe, which was junk, the second on I bought had the plastic round the edge and the digitiser.
I put it in and it worked fine no dead spots at all. Then 12 hours in it started to stop working intermittently. Then 24 hours after that while on charge its dead again. I reflashed notattrix and still nothing. I've confirmed all the ribbon connectors are firmly in place and everything looks right.
Any ideas whats wrong?

Replacment Digitizer Quality

Dropped my Atrix before i got me a casing for it.
I want to know how is the quality of the replacements glass wise is it still gorilla glass or?
I got my screen replaced at youbreak Ifix. The screen is identical, just be careful that it gets seated well or you will get a lot of dust under the screen..drives me crazy!

If you haven't already bought one take a look at this at ebay,
http://www.ebay.com/itm/OEM-Motorol...052?pt=LH_DefaultDomain_0&hash=item3cc340bee4 .
It is the digitizer and frame assembly. I just bought one of these for mine and I gotta say that I could not be any happier. For one it is OEM. Another I didn't have to seperate the frame from the glass or mess with glue tape. It is a b!tch connecting the ribbon cable back to the mainboard. But other than that it is an easy repair.
Oh, it looks absolutely brand spankin' new.
i replaced my digitizer with a part i got from amazon, big mistake, it was so much worse, looked identical but was just aweful, luckily moto replaced it for free as now i didnt have a broken screen it was still under warranty! good as new now.
edit: also looking at that post above, if you are going to do it yourself having it come with the frame would be great as mine didnt, so i had to use a hairdrier to heat up the glue holding the digitizer to the frame, real PITA
Yeah you're right ears1991, it was nice and easy not having to worry with separating the glass from the frame and then reattaching the new one. My phone looks better than ever. On the very first day that I ever owned it I handed it to my 24 year old son and he immediately dropped it. It put a nice gouge it the glass so until now I have never really had an Atrix that looked new.

DONT USE REPAIR UNIVERSE! Horrible customer service, no phone support, slow ass shipping even tho I paid extra for next day (got it in same time as regular shipping) and gave me the run around when they sent me a defective digitizer first time. Took me nearly a month from order to get what i paid for and only after I threatened to notify BBB of their horrible service.

I watched this video and only needed a small phillips screwdriver and a prytool. I haven't found a video where they show it going back together... Just reverse the steps and you'll be ok. The only hard part was getting one of the ribbon cables back in place. And I gotta say that cable was a b!tch. But I have large fingers and I still got it. So if you have some degree of patience and aren't afraid of messing with tiny stuff go for it.
thanks a lot. i just ordered from the person you suggested from eBay. ill give an update when it comes on Thursday and I replace it.
Cool, I just took my daughters apart, it is dead. I thought that maybe if I disconnected and reconnected the mainboard that maybe it would help. No dice. But I did find that using a pair of locking forceps helped a lot with the cables. Actually it was really, really easy. So if you have a pair, or know someone who works at a hospital that can get a pair, it is worth the trouble. Good Luck.
i just fixed, worked like a charm. and you were right, those damn ribbon cables were a pain. i can finally type regular letters again. lol.
That's great. Was yours pretty much new looking? Mine looks great, there are two tiny dimples on the upper bezel but they aren't easy to see. It's still a 9/10.

[Q] Help replacing Nabi2 digitizer screen...

Okay, so my Terminator...errr, my son, managed to crack the heck out of his Nabi 2 digitizer screen. The LCD screen is fine and he can still use the Nabi, but I've noticed more and more cracks so I'm sure it's bound to break the LCD.
So, I went on eBay and ordered a piece of glass, but I'm not thinking it's not going to work. It was only like 13 bucks. I had a model number given to me after the fact (at070tn90), and I just looked and I didn't get that one. I'm just hoping it will work.
At any rate, I finally got the Nabi apart, but I've been fearful of removing the connectors for the screen. Can someone PLEASE tell me how to get the screen apart so I can try to replace it when I get the correct glass for it? PLEASE! There are NO Youtube vids for this...tons for the Nexus 7, but nada for Nabi.
Please help...I'm desperate! Thanks so much!!
The likelihood the digitizer isn't cracked is very low.
NABI2 touchscreen layering:
front glass..............thick (glue around outer most edges to frame)
airgap......................very thin (glue around edges)
digitizer glass........thin
lcd............................thick
I tried the same thing but the actual digitizer glass is like 1/10 the thickness of the front panel glass and glued to it on the edges. If the digitizer glass is not cracked, it will probably crack on attempted removal from the front panel. If the digitizer is fully working in-spite of the front glass cracking it may be possible to heat the front assembly up to the point the adhesive allows the glass to just fall out.... but as far as how close the glue melting point is to the melting point of the plastic frame is not something I know. The entire assembly is put together with some super strong double-sided sticky tape. If you can source just the digitizer and glass assembly I'd like to know.
Once one attempts a replacement and it doesn't work is it still possible to get Fuhu/Nabi to replace the screen (at reasonable cost)?
( If not you could just plug in a keyboard/mouse and use the hdmi out... would make a great XBMC server... once the port exists... )

I already put it back together because he was taking everyone's iPhones to play games on. lol The glass anatomizer (or whatever it's called), had a long thin strip and the LCD had a thicker one. Either way, the glass nowhere near fit. I had a feeling it was going to be too hard to replace anyway; hence the reason I can't seem to find a tutorial on fixing a Nabi.
And yes, Fuhu will fix it for like 85 bucks plus shipping...I only paid 90 for the tablet just recently (Craigslist). Oh well. I guess we'll just let him play till he cuts his finger.
Thank you both so much for your input. I appreciate it
Help replacing Nabi2 digitizer screen...
Any luck on this?
I have a Nabi 2 on which I've removed the broken digitizer. It was a bit more difficult than I had anticipated. I had to keep the heat gun on the glass and avoid heat-damage to the plastic. I used a small knife between the digitizer and the plastic frame. Next time, I may heat and bend a cheap knife into a Z shape to get under the glass without lifting it too much. I did get it out in some large pieces, but am not sure if I could do it intact if it hadn't been cracked.
Anyhow, the LCD looks great, but I can't seem to find the digitizer anywhere. The ribbon cable has a sticker with the following:
EP0700MLM1

I am sorry for bringing back an old thread, but has anyone found a source for a proper replacement part for this? I am having a hell of a time finding a replacement part for the digitizer in my nabi2. It's as if nobody makes a replacement for the digitizers with EP0700MLM1 on the ribbon cable. About the only choice I have now is to find a used part, and pray that it also has the same kind of LCD screen within the housing.

I am looking at a few on Fleabay now. You need to take yours apart and compare model numbers with the ones on Ebay. Just search ebay for Nabi 2 digitizer. about 20 results for it, ranging from $25 -65. The $65 one is a complete front panel minus the LCD. just unscrew the top panel and replace, it looks like.
Wow...I'm the original poster...and here I am years later still bothering with Nabi! lol In 2014, I went on Nabi's site and paid $60 to have the digitizer replaced. I never sent the Nabi in because a friend of mine gave me his kid's Nabi to use for parts (he couldn't get it to charge any longer). I took the entire front panel with LCD and digitizer and replaced it with mine. Worked like a charm...until my younger son stepped on it...on purpose! Lil turd! So, here I am again trying to fix the screen, BUT, this time I noted that I needed the LCD and the digitizer (the ribbon on the LCD was breaking off - not sure how that could have happened). At any rate, I ordered both the digitizer and LCD. I replaced them both and it's a no-go...not working. I still have it apart, but I have the cables plugged in, so when I move the screen around, the Nabi screen will come up, but the touchscreen isn't working. I may be sending the digitizer back, but I'm wondering if it's because of how they are lying on one another. Does anyone know if maybe the touchscreen doesn't work if it's too close or too far from the LCD screen. I don't mean by an obvious amount - I mean is there a "specific" amount of space. I am trying to get it in the casing exactly like it was before, but I don't want to do anything permanent until I know it's working 100%.
Also, you can easily and cheaply get the LCD and digitizer for the Nabi now - just stinks you have to order it from China and it takes forever to get here! I can only imagine how long a return/replacement is going to take. Ugh!
Oh, and Nabi has yet to return my $60 bucks...I have spent way too much on this tablet!
I ended up having to match my part number to a used but good part off of ebay. I had ordered several "new" digitizers and they never worked. There seemed to have been a design change somewhere along the line, or some missing information that made mine not work with the "new" parts available at the time.
However, to answer your question, the digitizer will work completely separated from the LCD as long as the ribbon cable is attached (of course). Rather than reassembling everything, I would only connect the digitizer to see if it worked. When I finally found one that worked, I then committed to doing the full repair.
It was a very painful process.
Is it an easy thing to take apart and put bk together if you have never done this before my daughter stood on her Nabi accident it was under her comfort blankie opps screen cracked but works fine she's only 2 ( well advanced for her age) soI dnt want her to use it incase she cuts her tiny fingers doesn't feel sharp but dnt want to risk it can't find any view on u tube still many years on be nice if someone would do one haha
Honestly...
It was a pain in the ass to remove the glass / digitizer from the nabi. If you're not careful--as I was--it is real easy to deform the plastic bezel that the glass / digitizer and LCD reside in. I ended up having to buy a replacement bezel that already had a digitizer and LCD attached to it. The LCD was DOA, but the one from my original was fine, so I begrudgingly transplanted that too.
Test the digitizer FIRST before committing to installing it on the plastic bezel.

How do I attach a new ribbon to the motherboard?

Tried to replace my broken ultra screen but damaged the main ribbon that connects to the motherboard. Have bought a new ribbon but not sure how i should attach it. Anyone know?
The original ribbon looked like it was just glued on.

Made by robot...to small for human eye and precision. It requires you to have a facility to have it mounted again or a solder oven if you are able to handle the parts with this kind of precision needed.
Toss it in the bin or sell it...you can buy a new device for less than the cost of attaching it/send for repair and get a new motherboard.
If you know some old school gaming console modder you might have some luck. Not many have these precise skills these days.
Ok thanks for the info. Do you know if there is a way to boot the phone without using the power button. It appears that the new screen works as when I plug in a charger the Sony logo on the screens turns on as too does the pic of the battery. I just cant get the power button to work. It looks like this maybe the area affected from the small damaged part of the ribbon.
If only I could boot it. Pity its not like an iphone that boots upon charging.

If you can get the volume button to work you can boot the phone with fastboot reboot
anisotropic adhisive film/tape
the adhisive that attaches the flex cable to pcb is anistropic adhisive film. its fairly easy to attach the cable but the materials is very expensive and hard to handle. I have replace my ZU flex cable using a strip of this film and a spatula soldering iron or t-type soldering iron(because its T shaped). clamp the board firmly, applied the ADF, pre-heat it to 50°c, align the flex and apply heat 150°c with 3 kilos of force for 25 seconds and your done. I got my ADF form work.
Ive spent more than I wanted to, to fix my Ultra. £50 for screen and £20 for other bits and bobs including new ribbon and back glass.
Just annoyed that the rubbish youtube videos showing how to replace the screen did not make clear how to remove the motherboard from the phone without damaging the ribbon.
Anyway I will see if anyone can glue the the new ribbon to the motherboard for me but will only pay around £10. Some of the folks I emailed want £20 to just to diagnose the issue which was already clearly stated to them. Therefore it looks like this may not happen.
Otyerwise I will wait for a broken Ultra to sell on ebay for around £10.
Love this phone for its size but have the Z3 and Z3 tablet as my two daily phones to keep me going till the Z5 premium.

it is possible to reuse the adhesive if the adhesive on the connectors are not lifted or removed.
