[Help] Dead screen before and after screen replacement - Nexus 4 Q&A, Help & Troubleshooting

Hey guys, so a couple of weeks ago I dropped my N4 in water for about 10 seconds, as I was attempting to shut it down the screen flickered and it all went dead.
Fine, so after a week taken apart and in rice the battery is screwed, standard stuff, bought an OEM replacement battery, and then it turned on, worked as it should, except the screen was completely dead, no backlight no nothing.
Again fine, I order a non-OEM screen/digitizer/frame assembly, it arrived today and after being god damn sure everything is correctly assembled I power it on to find the screen is still completely off even though the phone is starting up and working normally (I can hear it unlocking, I can receive calls etc)
Is there another component that has to do with the signal to the screen that may have suffered from the water damage?

Bump. Can anyone shed any light on anything else to try?

My guess is you got a bad screen. There's lots of cheap ones out there. See if you can return it

I suppose it's a shame I can't know for sure cause the new one could be faulty, and the old one could be water damaged in some way.

Hang on, I just realised the digitizer works on both screens, I can unlock it and navigate what I remember from my layout just fine, it's just the display on the new one and the old one, surely that means something else is broken on the mainboard perhaps?

Grey Screen (NO REACTION) - Please help me out guys

Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg
C'mon guys:-(
So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)
Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that
sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance
No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com
you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it
How much would the last option cost?
And how much do you guys think HTC will chare to repair it?
http://cgi.ebay.co.uk/OEM-SLIDE-FLE...944?pt=LH_DefaultDomain_0&hash=item2a10708cb8
something like that if its the ribbon cable.... but that gives you the whole kit
http://cgi.ebay.co.uk/Touch-Screen-...K_Replacement_Parts_Tools&hash=item2a0fd454a5
thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one
Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.
looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey
Done
And thanks again for your help.
alrite glad i could help, if you get stuck or if the warrenty doesnt work come back
hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?
Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Well it's just like it was when I bought it, 2.2.1, only google apps, had to configure sim again no sms, etc.. But my phone is definitely now new because there are my scratches on the back of the phone.

[Q] just purchased a g2 for $30. screen doesnt turn on

The phone definitely boots up because the lights on the buttons flash on then turn off after some time. The keyboard also lights up. You can tell the backlight turns on on the screen, but there is no picture.
Anyone have any idea about what I should do? Thinking about trying to restore to a stock Tom somehow tonight. Then I'm thinking about looking for screen replacements.
I was curious if anyone has had this issue before.
Update 07/14/11
So I got the screen and switched the old one out for the new one. This one also only has the backlight turning on, but I noticed when I put a part back on, there was a little bump in the middle of the phone. Haven't had a chance to fix it, but I noticed it's a piece hitting this rubber piece that seems to "transport" the sound for the mic from the bottom of the phone to the actual microphone module within the phone.
Removed that rubber piece, and I'll try installing it later. I was getting some blue and red visible in the middle of the phone. Anyone know what's wrong?

ebay for the parts and look around for the link for repairs. I don't exactly remember the link, but it's in one of the "spring replacement" threads. Good luck

How sure are you it's the LCD screen? Replacement screens cost more than what I bought the phone for...lol
it's mostly the physical connection to the screen.
and on your note about it costing more than what you bought the phone for... there are tons of parts on the phone that will cost more than 30bucks. not much you can do about that since you got it non fully functional.

Never had to do it myself, but there is a cable connecting the two parts of the phone. That is usually where this problem originates from. It's not easy to fix though if your not familiar with fixing electronics from what i have seen.

I've taken apart my laptop completely and put it back together before. Completely as in taking the lcd off and different chips and wireless modules and stuff. I think it may be something I can handle. I'm going to take a look at it now. Restoring wont do me any good because not even the boot screen shows up.

So I completely tore apart the phone, got to the point where if I had another LCD screen, I could have easily switched it out. But I don't, so I just put it all back together. I really hope this new LCD will fix the issue. I really hope it's not some other motherboard issue. If all else fails, it goes up on eBay for $70-$100 as is for the phone. If I fix it, I just got myself a phone that goes for $200 used for only $57.
sure. goodluck with it. if you can do it then you're all set. good luck

Sorry. After some searching on eBay, I found some sellers selling it for a few dollars less than 30, e.g. 27.
But I decided to go with a seller who sold more than 200, who claims the screen is an OEM screen, and who is top rated. He sells his for $32. Which makes my phone $62 after all is said and done.
The housing has some scratches on the top and bottom though, which decreases the value a bit, but hey, if it works I'll probably keep it as a backup. Currently have the HD2, but I got a Vibrant with original box and accessories for $100, so I think I'm going to sell the HD2.
That was kinda off topic, sorry
LCD screen should be here by the 13th.
Updated OP
someone help =|
I don't own a G2 but I still think this could be a similar issue to what we get over here on the HTC Droid Incredible. First, what makes you believe its still a screen issue if it lit but just didn't throw picture? Usually thats the symptom of having the wrong recovery version for the device hardware version. Normally for us what happens is we will get somebody who is new and rooting for the first time and they'll end up flashing the wrong recovery or freak out because they don't realize the root process takes a little while and yank the cord. End result being exactly what you've explained above. Phone starts but no screen. So we end up having them do the ruu or a second option which we call a "blind install" where you drop whatever your p file(ours is PB31IMG.zip) so whatever it is for the G2 drop that on the SD and reboot to hboot and do the update process by simply knowing how long to wait between key presses and what keys to hit without useing the screen. Its a unique process and all very magical. Haven't lost a single Inc yet because of this issue.
Anyways bud just a thought...

It doesn't seem to be a ROM issue.
Update 7/18: Sold the G2 on eBay and still made a good lump of money. I was very happy, until another G2 popped up with the same exact issue. Got it for a steal as well, and I tried the OEM screen I got from eBay, and it was still having issues, and it seems to cause the phone to overheat while charging. Definitely a defective screen and someones getting a great deal on a decent condition G2 because I already took the payment after I figured it was the screen I got.
I'm going to try to get a replacement from the guy that sold it to me on eBay, but I already left him positive feedback thinking it was the phone's fault.
Will update probably late July or early August when all of this gets sorted out.
TL;DR: bought 2nd g2 with same issue, turns out replacement screen didn't work in the 2nd g2, too late to not sell the first g2, getting another replacement screen to fix 2nd g2. First g2 was in better condition though =|
SWEEEEEEEEEEEEEEEEEEEEEEEEEEEET
Just installed the second screen that I ordered, and it works PERFECTLY. Phone is perfect nowwww yay. I can't use it right now though, previous owned put a lock pattern on the phone...
Wipe the system and the data and start over.

[Q] Nexus 4 Broken LED Flash... Fix?

Hey guys,
A few weeks ago, my Nexus 4 went through the wash and in a moment of stupidity, I decided to take it to a cellular repair shop. When I got it back, they said it was broken, but with a new battery I managed to fix it. The problem is, the LED Flash looks to have been removed along with the puffy white part around it. Is there any way to fix this short of getting a new motherboard, because other than this the phone works fine. Thanks,
Attached are some before and after shots of the motherboard.

If it's only the LED light that is broken then just use it as is. The phone still works at most. Next time when a phone goes through hell in water, bury it under rice for a few days and let it do it's work.

Touchscreen dead strip!

I've noticed just today that there's a dead strip on the touch screen. It didn't do this yesterday. The Nexus 4 was dropped once from 2 feet high, but that was almost a month ago and everything worked fine until now.
The screen still looks beautiful, no dead pixels, no cracks, and the phone is in a protective case with a screen protector.
It seems to me that the digitiser crapped out, but I'm not sure why it happened so randomly.
A funny thing though is that when I drag something fast across the strip it works. And sometimes it'll recognise a touch as a long touch or two-fingered touch along the strip. Weird.
I attached a few touch test photos to show the issue.
Hopefully there's a fix. Has anyone else had this problem? And if you had to send it back to Google, was something like this covered under warranty? What should I do?
Sent from my Nexus 4 using xda app-developers app
You can try to replace the screen yourself or tell LG/Google to send a replacement via RMA. They have parts floating around Ebay
How risky/costly is it to replace it myself? And does anyone know if it's covered under warranty? Cause if is, it'll be cheaper just to get a replacement from Google.
Are there other ways to check if it is indeed the digitiser? I've seen that sometimes touch screen problems are software related. And if that's the case, it'll be easy to fix.

Depends. If you follow the instruction properly, it works well. If you screw up, then Google/LG wont be able to help. A lot of people have done it and succeeded. There are great articles on the web. The price of a digitizer would be about $50-70. I MAY BE WRONG WITH THE PRICING.

In most cases no. Because it worked well and suddenly stopped working. Thus Google would say that its your fault. If you are somehow able to convince the Reps that it wasn't your fault, then there is some hope. I

Anything. The phone might have overheaten to the point that it flashed a certain section of a digitizer. It may also be a battery problem that escalated. If you feel that it's software problem, flash a ROM a see if it works.
IMHO You should send it to LG and get it fixed for about $140~.
This problem should be covered under warranty. If you honestly haven't done anything to cause this damage. (I'm also clueless as to what a user could do themselves to make just one section of the digitizer stop working)
Then lasting 5 months or less would not be considered reasonable and you should be entitled to a replacement.
Remember it is down to the retailer to prove that you caused any damage.
And if you honestly did nothing and it just crapped out on you then you should have nothing to fear in sending it back for a warranty replacement

That happen to my iphone when it got water damage. But if you did not do anything wrong, it should be covered by warranty.

Yeah, I think the overheating might have been what happened to mine. I was using a blackberry charger and I think it might have overheated my battery and fried a strip of my digitizer.

This looks like a dead thread, but Ill take a punt. I dusted my old Nexus 4 off the other day, which had exactly the same issue with the dead strip on the digitiser. I had tried replacing the screen and digitiser (I have up trying to get the original screen off the original digitiser). The issue remained, so I tried a full factory reset, but that also didn't work. I am now wondering if I should get a cheap motherboard, or try flashing the stock ROM again. Has anyone else had any luck with either?

Touchscreen problem - is this a known issue or a hardware defect?

Hi,
i own my nexus for one week, and today i used a smart cover which caused some troubles.
first all worked like a charm, close the flap, display off, open it, display on. magnets, how do they work? ****ing magic! :laugh:
well, a couple hours later the touchscreen wasnt responding after shutting down the display. at first, after opening and closing the flap a few times the touchscreen worked again, but by now its totaly ****ed. if the display shuts down, all i can do is pressing the power button for a couple seconds and then start again. (it has nothing todo with the smart cover, i think it was just a coincident)
heres what i have done so far:
- factory reset
- flashed the stock rom (i only unlocked the device)
- re locked the bootloader (mainly because im pretty sure its a hardware issue and i wanna return it...)
is there anything else i can do? i know that there are many issues with the touchscreen, but from what i read, its about ghosting and other glitches, not a complete breakdown that can only be fixed by rebooting and occurs as soon as the display shuts down.
thanks for your help!
What brand of smart cover/case are you using? and do you still have the same problems even without the cover?

yeah, the problems are even without the cover. i thought there was maybe a problem that the hall sensor got magnetized or whatever, but that doesnt fit with the symptoms.
i use this case:

Yeah seems that it's more of a hardware issue that was probably caused from the case if anything. Good thing you already re-locked the bootloader since I'd suggest returning it for a replacement. Just don't mention anything about using a case . If you do get a replacement, maybe try a different case to avoid the same problem.
Is using a case with a magnetic cover against tos?

No, otherwise why would they have put the sensor in the device to react to it?
