[Q] Nexus 4 Broken LED Flash... Fix? - Nexus 4 Q&A, Help & Troubleshooting

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.

Buddy has a big flaw.

Ok so my friend has an HD2. He was at work and some prick dumped a bucket of water on him. So I got looking at his phone and it seems that the only thing wrong is that the screen will not come on.
I can get the bottom lights to come on and the volume is somewhat working. But the screen will not light up at all. My question is... is there a way to buy a replaceable screen? He bought it off eBay so I'm guessing that the insurance was unavailable for him. Or would T-Mobile US look at his phone and troubleshoot it?
Thanks in advance for any information.

best thing he could of done is to immediately remove the battery and let the phone dry out for a few days. I would do that now anyways. Then put the battery back in, let it charge, then try to turn it on. If its really just the screen, yes they are replaceable, but make sure he gets the lcd/digitizer combo, those things are almost impossible to replace separately.

how do you know the screen is the problem? could be one of the many chips on the main circuit board could be fried. In my humble opinion, take the battery out and let it sit for about a week in a nice dry area. try it after a week or so and if it still don't work, sell it for parts on ebay.
I think you'd be wasting your money, especially if you have never tried taking one apart before. I've fixed a few phones before but the thought of opening up my HD2 makes me cringe!
hey thanks for the response we will give that a go. and hopefully that works but ill start looking up prices on the combo now. thanks again
The best thing yoiu can do for a wet phone, like previously stated is take the battery out, and stick it in a tub of rice for atleast a few days. this will draw moisture out of the phone.
I must have been lucky. I dropped mine in the toilete 1 drunken night. it came out still on and working, then the volume started adjusting itself and the screen was going funny. 24 hoiurs in rice and it was fine except for a dodgy volume button which sorted itself within another day.
If its still not working correctly, you mayb have to send it into htc for repair and get the idiot who poured a bucket of water to pay for the repair.

[Q] Blue dotted lines in the display - WTD

Guys, I'm in big trouble. My Defy's display is having some blue dotted lines in it. It was not there till yesterday. Phone fell off from my pocket flat on it face. No visual cracks on the glass , but these lines has appeared.
Am i scr*w*d ??
Hi!
I've already experienced this issue after I dropped mine.
I just took the battery out and let it rest for 1-2 days.
What I experienced is, that the lines get worse, as long as the defy is in use.
Taking the battery out for several hours could make the shrink again.
So, before sending it in for repair, just have a try. I can't promise anything, but it worked out well for me.
Good luck!

Well, I guess the screen is screwed. If there are no visible physical damage to your phone, you can give it to the service centre. Make sure you flash stock ROM and get rid of 2nd init and root etc before giving it there.

Phone gone for service.. Waiting for the call from service center.
The exact same thing happened me a few days ago. I just kept rebooting the phone and pressed down firmly on the screen after every reboot. The problem went after a couple of days.

[Help] Dead screen before and after screen replacement

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?

HELP!! SOS!! Black screen by isopropyl Alcohol(99%)

PS: you can skip this deatils to my main problem
Somebody pls help me
my galaxy note 3 was water damaged nearly an year ago. But i was able to recover at that time by using isopropanol(99%).
In Detail: After water damage i loosed all hope for around 2 days, then outtanowhere i got this solution over the internet and then i submerged my phone's green board into that alcohol and then in rice. Unfortunately it doesn't turned on. I kept putting my phone outside under sun light, still the display wasn't working. Then i left my phone for about 1 and a 1/2 month in my cupboard abandoned....It got fully recovered!!! i was living a happy life then.
:Main Problem:​Now in today's date i was feeling something is wrong in the phone because it was discharging these days too quick(abnormally and this things were happening after recovery too). So i decided to put the whole phone(deassembaled the green board) in the isopropyle(99%). after 30mins later i picked it up back and assembled every thing back turned on the phone and guess what the screen was black again. I putted the phone under sunlight again but case got even worse (but i think it is good both) at the same time. My note 3's screen is turning on and working but inplace of black screen its showing dark smudges or a quit a bit of screen(not cleared but seen-able) like some kind of weird shape/spots of black. Now HELP ME
Tell me what to do!! i don't know what is this happening because 99% isopropanol isn't that conductive and will not harm the phone whatever the case is.
What should i do to get all the things back at the track? should i submerge the phone again in alcohol or should i leave it for now.
*i hope somebody read this, waiting for reply and help*
BTW: i'll keep updating this thread if something happens
Whats the 1% ?? Water ??
When a phone gets wet, I never recommend dunking anything in alcohol or any other liquid, especially the screen. Sounds like the alcohol may have seeped in between the glass and LCD.
Update:
So after putting it under sunlight for 2 days. My phone's screen is completly BLACK.
just a tiny part was showing lighted up but that also gone after about 15mins.
What the heck should i do now. I removed the battery now and putted the phone in the cupboard again (hoping for a miracle).
Any help will be appreciated.
New screen or bin the phone .

You made a huge mistake by placing the phone in alcohol. You should only submerge the motherboard. It seems like you have alcohol/some water inside the display assembly now.
Use a hairdryer to completely dry the motherboard, place the display/ rest of the phone in rice and give it 3 days or so.
Should work.
PS: You may have killed it by turning it on while it had the spots on the display, i.e.. caused a short.
Good luck.

days lol nothing happened. It seems that rice done nothing, my screen is still black sadly. My phone is booting and speakers etc. everything is working fine the only problem is in the screen.
Please don't forget to read my detailed post in which i stated that-
nearly a year ago i was able to recover my phone which was water damaged and for that solution i gave a bath of isopropyle alcohol. And after a month i was able to recover my phone just by putting it somewhere without battery
So at last i want to only ask you what the heck should i do to GET MY PHONE BACK AGAIN HELP!!!!

It takes effort to accept that the best thing to do is just to get a new phone. I remember when I wanted to stick to my old, microUSB-port damaged Galaxy S II but I had to accept that I needed to move on.
I know sometimes it's difficult ($$$) but yeah, save some money up and you'll see that this will be just a small episode in your history of smart phones.

maybe.....
but seriously it maybe any kind of impurity but i'm sure it is not water.
I would suggest to buy a new phone. You could TRY changing the screen, but there is no guarantee that the screen is the only issue. + a used Note 3 is almost the same price as a new screen.
Sorry that the method I suggested did not work. :/
Since this didn't work, you probably fried the screen driver when you turned it when it was filled with liquid under the display.
Change the display or the phone.
Never, ever attempt to turn on a liquid damaged device. I know it's tempting. This is an expensive lesson!

You dont need to say sorry bro.
Well from all the experience i gain from this incident and including my experience with isopropyle alcohols, i don't know definitely what happen but i can guess what may be going on there.
So, in recent months a previous phone (not my phone) was water damaged and the owner gave it to me as a last hope lol. I 100% submerged that phone in isopropyl for 3days!! lmao and as a result the phone's some part like speaker and screen (which are stacked by an adhesive) were floating in the solution and then i picked up that phone up and situation got even worse the phone's screen was a bit hanging i turned the phone on and the screen was working perfectly but as i said the phone's screen was hanging so it was not touching fully the digitizer and hence the touch was not working but the screen was turned on i dunno why.
Now i look at my phone which screen was just dipped about 15mins and still not able to show anything. I think the cause may be a part between the screen and the phone which might be displaced by that solution.
Now i ask you guys that should i remove the screen only by heating & removing and stick it again. Will this solve the problem? any advice?

no LED backlight on most of screen

Hello all,
I dropped my phone in a shallow puddle and put it in rice for a few days. All seemed well, everything works 100%. However the LED backlight isn't working on most the screen. I dropped it off at a repair shop. The took it completely apart, cleaned everything up and they saw some irreparable damage on the circuit board for the LED backlights. Absolutely everything else works 100%. I also have a week old poetic case and another slim case, the extra battery kit and there is no scratches on the screen or body of the v20. How much would I be able to get for it? I'm looking to move away from Android for a while. I've been playing with my coworkers iPhone and I dig it.
maybe $50 in parts... maybe another $50 for accessories.
