Want your opinion on this phone black screen issue (see picture)...

My wife's phone got water damaged a few days ago and I took it apart and removed as much water as possible and put it in a bowl of rice to set.
I finally tried turning it on today and it seems to work fine (I think, syncs etc.) except that the screen does not power on. I can see the backlights when I look at it from an angle so it appears to receive power of some kind.
I took it apart further to see if I could see anything and I found that on the display cable there is a black area which looks like it is damaged/burnt on the cable. There was also a little bit of black on the connector but I believe I got most of that cleaned off, but the area on the cable does not seem to be able to be cleaned.
I don't really know anything about electronics or parts of a phone and was wondering if anyone that did could suggest what my next steps would be to restore the phone/screen to operational condition? Part replacement etc.
Thank you.

It sounds like the chip connected to that cable got fried, hence the burnt spots.

If that's the case I'm assuming there isn't much I can do? I don't want to solder anything but could can replace anything that just snaps in.
Thanks.

[Q] Nexus S not recognising charger?

My Nexus S was recently upgraded to 4.0.4 stock a month ago, and has been running perfectly without any problems. However tonight I've noticed that when I plug it in, it doesn't recognise that it's being charged (when the phone is on or off), whether this is on the lock screen, or how it used to display the lightning bolt over the battery. It just keeps telling me to connect my charger.
I have no idea why this has suddenly happened and am wondering if anyone else has had any similar issues, and how I could fix this?
Thanks

Clean the USB port?

Either the USB port has some dirt in it preventing the charger to make proper contact or you have faulty hardware. Doesn't seem anything related to the software since it doesn't recognize the charger when it's off.

stupid question.. have you tried a different charger?

Thanks for the quick replies. So last night I left it on charge and the battery fully charged however it still isn't telling me that it's actually charging unless I go to Settings>Battery to check there.
I tried using a different charger but no luck, and also using a USB cable to my laptop. Also it isn't showing me that I am able to transfer files via USB connection anymore.
I did clean the USB slot using compressed air and still no luck after that.
What I'll try now is a factory reset to see if that remotely helps anything.
Cheers

So I tried resetting the data etc. through the bootloader but still no luck Any ideas?
Thanks again,

Ok so it's gotten worse. When I power down, the phone hangs at the Power Off part, it vibrates to shut down then the phone freezes at that screen.

Ok I fixed it. It turns out that the micro usb tab inside of the phone tends to drop on the Nexus S, so I took a knife to gently lift up the tab and secure a better connection and every single problem has been solved.
Thanks to everyone for your quick responses, it's greatly appreciated.

Good to hear you got it sorted. I'll keep that trick in mind.

I've been trying to find the solution for this very problem for the past couple days.. Thank you, thank you, thank you! Worked perfectly.

Mine is doing the exact thing. Still charges though

Hi, I am having this exact problem, but before I do your trick, I just want to clarify:
by micro usb tab you mean the tiny tab inside the usb port of the Nexus S? Basically the tiny tab that goes inside the usb cable when you connect it?
Thanks!

[Q] Screen drop outs and now always black, why?

Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help

Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you

I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.

even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past

Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well

So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(

Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?

There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

Nexus 5 black screen

My N7 4.4.2 Not Rooted has been playing up lately. For the 2nd time in 3 days, I picked it up and it wouldnt respond. I could hear the screenshot being taken so the phone was on but the screen was black. It vibrates after using the power button and it finally boots up again. The phone has been perfect for about a month and this error only started recently.

Do a factory reset. Keep in mind that this will wipe your internal storage so be sure to back up and data, photos, etc. before hand. If that doesn't fix it then flash the factory image over. As to how, refer to this thread.
Your problem should be fixed after the Factory Reset though. Good Luck!

Thanks. I was hoping it wouldn't come to this but oh well. Is there a cause for this?

Were are talking about the N5 right?. I had this issue with my G2X a couple years ago. It turns out that after I took it apart the flex cable looked like at had been torn a tad bit. This sounds like a flex cable problem. Software could be the issue and a factory reset may help. However in my experience that's usually a flex cable or pop connection. Send it in if the reset does not work. Don't bother trying to do this yourself. It may be the front panel flex cable. Or the pop connection of the main board. When these cables are made, they are literally thrown into barrels and sent to The front panel assembly line. So chances are. One of these flex cables suffered some damage. Same goes with the tiny connection on the main board. These tiny pieces are put on one by one. I think robots do it. The device turned on for their tests. But the long run? ...Well you get the point.

Im just facotry resetting my phone right now, i'll post later the results after a few days of testing

Well? did the factory reset work? I have this issue and it's driving me nuts!!!! I read somewhere that squeezing the case helps, and indeed this seems to work something, to it looks like hardware issue to me

black screen nexus 5
I was totally desperate with this random black screen. I tried everything including change of flex cable and also screen, but the same random black screen
I changed the 2 years old battery with a new one and.... ooff... this resolved my problem .no black screen anymore
I hope that, with this solution, I give You another direction of thinking about what is causing this annoying problem

[Q] USB charging port

First, I bought this device the day it came out on ATT. I love it, but I do not know if is a malfunction of my phone or all of them are the same. When I try to connect the USB cable it gives me a really hard time cause is like if something is blocking the port. I have tried with different cables, but all of them give me the same result. I have to push really hard to get it connected and I think is something that should not happen, I want to know if you guys have the same problem or if this is something happening just to me. Thanks. :fingers-crossed:

When inserting your cord tilt it down after you first insert it. Takes a bit getting used too, but it's smoother that way. Mine does that as well.

I'm glad you posted this as I picked my last Wednesday from T-Mobile store. Everything works great on the phone , the only issue is plugging the charging cable in. I tried my other chargers as well but same with all of.them. trick is to tilt downward and it goes in. I don't know if I should exchange for a new one?

Same here. I don't think it's a big deal. Just gotta angle it a bit

It's that way for everyone. Once you've done it a couple times, you'll start doing it without thinking.

Yeah, same here. Though I have noticed that the micro USB connector on the stock cable features a couple of extra "hooks" that my other chargers don't have.
My old charger connector goes into the G3 a lot more effortlessly. However, when using that non-LG charger, the phone buzzes randomly for the first few minutes after being plugged in. Sounds like I'm getting a notification, but there's nothing showing. Bugged me to no end, so now I'm back to the new LG charger. I may try to just swap out the cable and see what happens.

Yeah there's something up with other Micro USB cables.. My car charger causes the phone to do this exact same thing.

Mine does the exact same thing. One thing I did notice is the charger seems to fit better and be more snug, making it less likely for charging issues to occur like the cord coming out. Im still getting used to the way to plug it in, but i like it a lot more. I constantly had the cord being loose or having to be in a certain position on my HTC One X+. Glad to know mine isnt the only one that way. :good:

Any new updates on this? My still needs to be tilted in order to get in. I don't think this will change?

Both of my G3s do this. I had a F400S (Korean model) and it was the same way. Its most likely how it was designed.

Even i had the same problem. First i thought i got a phone with malfunctioned usb port, then i found that i have to use a different angle to push the cable in.

it makes it more secure, you're less likely to break it this way... it's not a bad thing

my new tMobile G3 is doing the same freak'n thing.
the phone itself is [email protected]$$ but the port is def. a manufacturer defect.
I don't know where every one is getting this, "more secure" b.s.
It's not more secure and it may very well snap that small extension in half after some time if we're not careful enough.

I think the idea is to give the port a little more flex. there are a lot of returns on phones is the usb port coming loose, and causing improper charging, i think it was an attempt to fix a problem... and your right only time will tell if its worthy fix or just BS... lol

Glad that I found this dedicated thread
I think the fix is way worse than the problem? Now I have to teach my wife.

thank you sharing your experiences
I got a D851 (G3 T-Mobile model) from ebay. I kept thinking it's the cable I used. I don't have this issue on other devices.
I am so glad you sharing all the info here. I was thinking about exchanging it after trying different cables and all does the same.
Thank you guys sharing your experiences here. :good: :highfive: :victory:
