No display on nexus 5 even after screen change - Nexus 5 Q&A, Help & Troubleshooting

Recently, I purchased a Nexus 5 from a friend. The screen was completely shattered and nothing would appear on the display, but my computer was able to recognize the device. This morning I replaced the screen with a new one, however, there is still nothing appearing on the display even though the computer recognizes it and there is still life left inside of it.
Is there anything I am missing? I rechecked that everything is plugged in correctly several times and still nothing. I was thinking of replacing the flex cable, but I am low on funds so I don't want to waste money if its not going to work.
Attached, are photo's of the device.
Any help is greatly appreciated.

did you replace just the screen or the whole Assembly with the lcd and digitzer?

Yes, the entire assembly has been replaced which includes the LCD and digitizer.
Once again, I'm thinking its the flex cable as bad flex cables I've had with other phones have affected the functionality of the device.

It was not.
In a nutshell, my original question was basically 'could there be another problem with the Nexus 5 that I am unaware of?' which was not answered.
The second poster simply asked me if I replaced the LCD and digitizer assembly in its entirety.
The third poster is me posting my suspicious about which piece of hardware is causing the trouble.

Oh sorry you said flex cable. I was on my app. My apologies. Honestly it could be the flex cable. I replaced the screen in my Droid 3 and it didn't work because the flex cable was damaged.

Based on your photos it looks like what you replaced should have bean sufficient but of course with electrical components who knows... I wouldn't rule out a dead replacement display either. I'm in the middle of a similar situation, returning my replacement display today and trying another.

Could be a number of things with that physical damage, not just the screen

So you were able to get a display after you changed the flex cable?
The odd thing though is that I'm still able to charge the phone...the flex cable also holds the usb port.
Anyway, I've ordered a new one so we'll see what happens.

If anyone was wondering the screen still does not work with the new flex cable. I'm assuming its a motherboard issue and am just going to sell it on eBay.
Before than, any other suggestions would be appreciated.

I bought it from him for a very cheap price ($30US). Even with it broken, I can still get more for it by selling it on eBay than I can by getting my money back.

Try to make preassure on the wide connector on the motherboard. If display backlights or displays temporarily it's micro distached pins between connector and motherboard. Heat Air is the easy solution! In my case I used hot air heatgun 350°C and 10sec on row near edge of the board. The solder melts and at that time PUT slight PREASSURE down to the connector for few seconds! It makes the legs got proper contact to the pads on the board. Solves problems with Mic and Loudspeaker too becouse it relay on this wide connector.
Good luck Tomáš

Spare parts inside....

Hello everyone, I considered putting this in the marketplace but it makes 100% more sense to have it here.
I'm selling my faulty nexus one for spare parts so if anyone needs a part of the phone (except the PCB that the microusb sits on)
give me a PM and we can come to some sort of arrangement, obviously undercutting ebay prices lol.
for example... lcd replacement, digitizer or camera, speaker, volume buttons etc.
I've got a weird one to ask about....
What about the bottom soft touch cover (that goes over the usb port)?
do you have the little black plastic piece that covers the bottom pcb? its got the little vibrator connected to it.
Mine is like slowing down and isnt as powerful and i think its the reason for my haptic feedback dying

Hi Magacamz! I wonder if you still have your LCD Replacement? For how much are you expecting to sell it? Would you send it using USPS International? If positive, we can arrange using Paypal or something similar...

It is literally the piece that goes over the USB port and gold power connectors on the bottom of the phone. It's the same material as the battery cover.

DO NOT try to replace the screen by yourself

I dropped my three-week old HTC one X on driveway by accident. The screen was shattered like a spiderweb. So I ordered a HTC One X screen/digitizer replacement from Amazon.
Today I tried to follow each step described in youtube ( http://www.youtube.com/watch?v=ceHw6mezG60). In the last step when tried to separate glass screen from LCD, the LCD was ruined.
The glass and LCD were glued very tight. In my opinion, it is almost impossible to separate them safely. There are some differences in cables and connectors between the US version and the one showed in youtube (i assume it is the international version). There is one cable in the AT&T version that is very hard to disconnect.
Just to be clear, I consider myself very handy in electronics. I hope you can learn from my lesson. Tomorrow, I am going to send the phone to HTC repair center. Since I voided the warranty by disassembling it. I have no idea how much they will charge me.
i learned my lesson on this with a friends Inspire 4G...I have changed many many iphone screens, but the Inspire was a whole different ball game, and i would expect the One X to be even worse.
You are right, pay someone to do it.

Why don't you just order the whole LCD/digitizer/glass module? And of course the things gunna be hard to separate, you need to heat it up A LOT to loosen the glue

Agreed
I learned my lesson with iphone/ipad digatizers. Of course its less than half the price for just the digi but the lcd/digi combo is definitely the way to go. If you do get it separated you have a lot of cleaning to do to get all the old glue/glass off and they are much harder to get back together than you would think. Also invest in a good set of tools. The tools are garbage that they send with the parts.

A screen is about $50, and a screen/LCD combo is at least $180. If I knew it was so hard to separate, I would probably order the combo. Another concern is, I am not really sure that the LCD/glass combo from ebay is as good as that from HTC.
Fyi I had HTC replace my cracked screen. They also replaced the housing (new case, yay) for some reason. They had it for two days plus 3 days shipping time to get it back. Total cost was $220. I'm handy in electronics but seems this is the way to go for now based on costs for the full assembly. They really had great service through the process and you can track the repair online.

Oh how I wish I saw this thread before..
So I sure did break my digitizer.. and when I tried to replace it, it sure was glued to the LCD, and it did come apart lol. On the brighter side, I got a new digitizer and tools, I ordered an LCD but they shipped the wrong one.. but I will say this, I don't think it's that hard to take apart and reassemble.. aside from everything being glued together, and from what I gather the international version is not this way. Everything seems to make sense. I am starting to get lonely without her working. Sometimes I ADB into her just to say hi, mount my storage and make sure I got everything out just in case I butterfingers it and short something out. So aside from my agreement, here are the lessons I have learned.
1) Have a hair dryer handy, that glue is like concrete.
2) Don't just tug that battery cable out, the wires will come out of a socket (took 2 hours to get em back in)
3) For those of you whose digitizers and LCD's are broke.. "adb shell /system/bin/sdutil ums enable" will mount your storage so you can backup some stuff.
4) That torx screw driver you think you might need, haven't seen a torx screw yet, just loads of glue.
5) Take pictures of stuff before you disconnect it, and how you disconnected it for reference in reassembly.
6) This is the correct part # for the LCD 60H00664-01P, except no substitutes.
7) There are little crystal gluey things on the back of the digitizer that go through the case and transfer light. Don't expect them to fully light up ever again without remembering to move them (if you can)
8) It's worth fixing, sure I pre-ordered an HTC-One, but my One X will remain my phone because I love her, she's my first HTC and by far my best android ever. My HTC-One will be for Dev purposes >
9) Resist the urge to take the heat shield off to see if you can upgrade your storage by some kind of hidden micro sd, even if there is one, I'm sure it's got 5lbs of that crappy glue AT&T insisted upon.
10) If you think you want to change your digitizer just to rid your self of the AT&T logo, It's not worth it, I'm in it for 18$ for the digitizer and $43.99 for the LCD. Sure it's worth the money, but my sanity is long gone, I will name my next dog sanity.
You guys are the best ever! Good luck! God Speed!

I think I might do this if AT&T doesn't let me take my upgrade early to the One. So you would recommend HTC to do this? Just out of curiosity, was your phone rooted/romed when you sent it in? How long ago was this done for you?

Well..
Not that if he can't do it no one can, but the threshold of glue being heated to separation vs. the heat destroying the lcd is so close.. and the parts are so cheap to get independantly of one another. In the words of the hunger games.. may the odds be forever in your favor.

Hmm..
LOL figures I would run into a problem like this, new screen stops the phone from booting, old screen fires up the phone, if i plug in the new one while its running, the new one works fine, if i restart, back to death.. i could reassemble with it still running and pray i never need to restart my phone, but that would be messed up.. any ideas?
I've never had problems with it. Even while drinking. Just apply heat, then pull. If it doesn't come that easily, then it isn't hot enough or hasn't heated evenly.
Btw the combo fpr screens and digitizer rins $50-75 on eBay

Hello
Alright, so I had my lcd digitizer combo replaced, since the glass was broken. At first the lcd didnt work because it was AOM or something like that and wasnt Sharp's model like originally, but i syncded it as follows:
1.Took out the battery
2.Connected the old screen
3.Put back your battery
4.Start your phone
5.Wait about 2min to be sure
6.Take the old screen and replace it by the new
7.Press power button
8. Should be running and working.
But now.. after assembly it does detect the sim card, but gets no signal, so i cant make calls go to internet etc.. But wlan however does work ?
is there something I broke in the progress or ..
Hoping for some help, thanks

Sure sounds like you didn't re-connect the cell antenna correctly. Those ribbon cables are a *****. Could also be the little EMI tabs that come off of the blue antenna PCB and connect to the case, I would think (just guessing, as I'm staring at my disassembled phone right now).

Screen replacement problems

Hey everyone,
I recently bought my HOX at my local AT&T store about a month ago and managed to drop within the first 2 weeks I had it, and break both the glass and LCD. I went on ebay and bought both the LCD and glass together and installed it on my phone with no luck. Screen is totally black with no response. Everthing else works flawlessly, vibrator, capacitive buttons, and speaker. The aftermarket LCD screen's cable was straight so I had to make a fold in it like the original cable was. I worry that that might be what the problem is, though I highly doubt it. I would appreciate it greatly if someone could give me some advice on what I should do at this point. Return the LCD and glass or try something else. Thanks

Welcome, search the forum. Long story short, call HTC and have them fix it for ~$220
If you signed a contract when you bought the phone and are still within 30 days, I would just have AT&T add insurance to your line and make a claim for it.

Try both the old one and the new one without placing it into the housing...
The problem you will face most is with the LCD strip which has to be inserted fully in the slot..
Which is very difficult to do so and needs lots of time on it...
see some Replacement videos on Youtube. It do show you step by step guide on replacing the LCD..
Just place the battery and all the connectors and try powering it on b4 inserting it into the housing..

Yeah i think the new LCD is broken. With a flashlight i can see Android on the screen
So i think the backlight is broken. So i will repair the phone with a new Display and Digitizer Unit. Right?
I tried the same thing, but mine was just the glass. Forget about trying to separate LCD from glass, really you are not that skilled (any of you!). anyway, It was about 45 days after receiving my HOX and I called ATT and just told them what happened and that my phone was in 1000 pieces, said I now have a contract and no phone (though I was much more miserable and depressed sounding at the time). She said "no problem, I will just toss out this old contract and we will start from scratch" It cost me another $99 but they sent me a brand new phone. I was shocked. First time a carrier ever made me smile (other than running LTE Speed Tests)

[Q] Digitizer/Sensor or Flex Cable Problem?

It started out simple. At first, the screen would cut off when I closed the keyboard sometimes...and then all the time. Next, the touch screen stopped working. Afterwards, the screen would freeze occasionally. Now, I can't see the screen at all.
I'm not ready to give up on this phone yet. I'm just not sure if it's a digitizer and sensor, or the flex cable issue. Does anybody have a clue?
90% need a new flex, be sure to get one with the speaker soldered on to make life easier and take your time reading before disassembly, lots o sticky stuff there
Sent from my Nexus 4 using XDA Premium 4 mobile app
If both the LCD and digitizer are having problems (with no signs of external or water damage), I'd suspect the flex cable as well.
Thanks!
I thought so, but I was in denial. I've only ever replaced digitizers, so I was hoping I just had to do something like that again.
By the way demkantor, what's the other 10%?
9% digitizer going bad and then soon after LCD, 1% software/firmware issue 90% get a new flex. So if it were me id buy the flex, or at least open it up and have a peek around
Sent from my Nexus 4 using XDA Premium 4 mobile app
Changed my flex two times by now, first time lcd showed color noise, second time touch died.
First time there were rips on the flex, second time - nothing particular.

My MT4GS has just gone blank after 3 years of continuous use. Screen went random colour pattern, then totally black, though phone is still working fine behind it.
I've done a search, but places like http://www.etradesupply.com/htc/android-models/htc-mytouch-4g-slide.html suggest there are two - a motherboard flex and a slide rail flex that look very similar but are two different prices. I'm a long way from USA, so spares take a long time to ship and are expensive.Can anyone recommend a supplier/specification so I get the right one? Help much appreciated. Thanks.
In the link you sent those are one in the same, can't say why the prices differ but one may have speaker and one not, I'm on mobile so its hard to zoom in and tell.
As for supplier I'm in the us and have just purchased from random eBay people before so I can't say what's best for you
Also note it is possible you're LCD is bad (but bless likely the cause) if you are to get one of these know which one you have first (there are a couple out there and aren't interchangeable)

Thanks - reading other posts on other threads (inlcuding one guy who posted a picture of exactly the last thing I saw on my screen before it went black (-http://forum.xda-developers.com/showthread.php?t=2092608)) seems to point to the flex. That post also has a link to an ebay sale, but the picture has been taken down so I've only got the name to go on. And of course that doesn't match what I can but other places so I'm just guessing at the moment..
Is it the main motherboard flex? Perhaps I'll have to strip the phone at the weekend and see if I can work it out... Oh well, another thing to add to the To-Do list. No wait, that's on my phone and I can't get at it!

[Q] Digitizer not working after reassembly

Hi everyone.
So i tried to replace the cracked screen in a Moto G (I just replaced the display+digitizer+glass module). After the reassembly everything worked except for the digitizer (it worked before when i tested it). I tried to reconnect the digitizer connector (the tiny one which connects the digitizer controller to the display connector ) multiple times, but nothing worked. Has anyone faced a similar problem before?

So i tried to replace the cracked screen in a Moto G (I just replaced the display+digitizer+glass module). After the reassembly everything worked except for the digitizer (it worked before when i tested it). I tried to reconnect the digitizer connector (the tiny one which connects the digitizer controller to the display connector ) multiple times, but nothing worked. Has anyone faced a similar problem before?

Hi, I have exactly the same problem.
In my case, it's my second screen, so I've already eliminated the screen+digitizer and the cable connector like the origin of the problem.
Has anyone any idea?
Thanks!
PS: Ening, did you get to solve your issue?
much sad

Bad news. My digitizer cable is damaged. On both original phone and the donor. I was not careful enough: the closer inspection showed it. I am going to order another screen or a donor phone (like a used verizon one or something) and try it again.
So the thing is that the video on etradesupply shows it wrong. You have to unstick the tape covering the digitizer cable connector, then unsnap the clicky thing, and only after that should you unplug the screen master cable (the one that goes into your PCB). Otherwise, it is very easy to damage the touchscreen controller cable (the digitizer one).
I really hope you have a different problem and there is still hope for your phone :crying:

Hi Ening,
How do you check the veracity of the cable connector failure? I think I have the same problem than you, but I haven't a way to check it 100%, because I haven't anyone who can lend other screen to me, and the original screen it's now completely destroyed.
I suppose that I will have to send back the screen to the seller and ask for another.
Thanks anyway!

Hi, i gave the phones to a guy in a repair shop and he looked at it through a magnifying glass
agnobi, I have exactly the same problem, but tested several digitizers and same problem
see my post here : http://forum.xda-developers.com/moto-g/help/black-screen-backlight-ok-screen-t2803431
did you solve your problem ?
Me too
The new digitizer doesn't work and now the 'old' digitizer dosn't work anymore
Everyone has found an solution ?

The flex cable part that connects the controller to the rest of the cable is very thin and easy to damage, you've to be very careful or you're gonna screw it (like the OP did).
ofcourse there is a slight possibility that it came defective, but you should have checked it right when it arrived. So far I haven't seen any incomparable ones, but who knows.....

I think there is something else.
On my side, the 3 digitizers (old one + 2 new) give me same result.
The I think the problem should be on the mainboard or a hardware/software blocking ... or maybe something we didn't re-assemble well
and little question : what is the role of this part (see my photo) ???

Probably the last :>
That thin metal plate makes connections on the back of the PCB (its mounted right between the display and the PCB) and I think it connects to mass.I got no idea what it's role is (prolly its a fitting or some sort of heatspreader).I've assembled one phone without it and it worked just fine, but I've put it back afterwards, just for the sake of being complete
and your digitizer works fine ?
I think also that the issue comes from the connection PCB-patch or as you said software digitizer blocking.
So I 'll try to flash a retail rom to see it .... ...... The digitizer still not working

I've replaced 9 digitizers on 9 different moto g's.None of em had any kind of these problems.This leads me to the conclusion that you've done something wrong.
The worst I had is 1 dead pixel on one of the new displays ( I'm using digitizer+display+frame assembly ).

very interesting your experience ...
the strange thing is that we are several persons to have the same problem and the same symptoms ...:silly:
I've unsnapped the connector as they said in the video of etradesupply...
Maybe I've forgotten something.... you have followed this video ?
Edit :My screens are working except for the digitizer.

I've followed this same video...
I don't see what I could have done wrong
liveroy : you never expected that black screen problem ?

I've also reflashed a stock ROM ... no change
so it's not software/firmware related ...
so it's hardware
Never, all worked the first time and afaik they are still working fine.Gotta mention that the ones I`ve used are chinise ones, but look and feel like the original, even the glass feels like gorilla glass 3, altough I don't believe that's the case :>
I have a huge scratch down my screen and the local mobile repairing guy quoted £55 to replace.. I thought this was a bit steep.. I expect him to use real gorrila glass 3 @ that price
Sent from my XT1032 using XDA Free mobile app
finally I've just fix my digitizer
It was 1 or 2 pin twisted on the right so there wasn't a contact between the PCB and the patch....
denseye I think your black screen can be fixed, you may see the pin on the left...." Bon courage " PM me if you have questions....
I've got now my earpiece which crackle but I thinks I'll not try to fix it....
Good night
You mean a pin on the pcb connector where thé LCD câble goes? (Français???)
A pin means a spindle which links the patch(LCD câble) to the PCB.There are many pins which compose thé connector.
(Yeah I'm french and i've sent you a MP.... "Dur dur le correcteur ortho ...")
