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.

Bump for last ditch effort to get some opinions before giving up.

Anyone replace the charging port yet?

so i've gotten my hands on a galaxy s3, which i'm super pumped about, but it had a bad charge port. seems to have been corroded with sweat (the woman ran with it in her shirt lol) so i cleaned it up hardcore with some rubbing alch etc, but i cannot get it to charge correctly anymore. basically, it might charge half a percent per every hour or so....like, something incredibly slow. last night i left it on from 8pm until 10am the next day, and it only went up about 26%.
when plugged into PC, the comp tells me unrecognized USB device, blah blah blah, can't install drivers..so clearly there's something up with the charge port. now i've found a replacement on ebay for only 5 bucks, which is awesome..however, i don't know what kind of task it would be to replace the charge port, as i've never done it before.
anyone have any experience, or have any better methods to clean out the current port? i've used a toothbrush with rubbing alch, and then a toothpick to fine clean it in there, and then i blow it out with compressed air after i let it sit a bit just to fully dry it out. again, it'll charge, but so horribly slow...and thing is, it even says AC charging, too.
here's a pic as an example:

Why wouldn't you just go to Verizon and get a replacement? or even a 14 day swap if you're in the 14 days?

lol bc it's not my phone..i bought it off a customer at my store since it was busted (she bought another one lol) and either way, we can't warranty it because she has two small cracks in the two corners..she's obviously dropped it within the 1 week she had it anyway.

What??? Jayochs! Sorry I don't have anything to contribute but there is a thread on here of a guy who disassembled a GS3 so maybe that will help you get an idea?
Here's the link to that thread http://forum.xda-developers.com/showthread.php?p=29166420

that's IF i can get this thing repaired lol

so i got the charge port today finally....i also got an external battery charger and 2 aftermarket batteries in the mean time (problem is it takes like 10 hours to charge from 0 to 100%......crappy charger)
so now i have this tinyyy little USB port, and i've never really taken a phone apart before, especially doing soldering work on a PCB.
does anyone have any experience or anything replacing it on this phone yet? i'm scared to do it myself, but i absolutely need to fix this charge port so i can charge normally and root, etc

damn, nevermind...just read that you need a hot air soldering gun to do it, and i don't have one of those. i guess there's nothing left to do but just swap batteries in and out of it..no root for me

You could always take it to a pc repair shop. They'll probably charge you $20 to do it, especially if the phone is already taken apart.

I would gladly fix your charge port for a price. The main thing about diy is do not be afraid of breaking something, your s3 and other electronics are built sturdier than people think...... Think how hard people drop em and they still work. But don't just go taking on stuff, be careful just don't be afraid and renege where everything went and in what order. Its really simple. I've been working on phone hardware and xboxs, ps3s etc for a few years now..... I'm just not getting into the software stuff

If you are really worried about doing the repair your self, and can't find someone to do it at a reasonable price......I would just do the palm stone wireless charging mod.
The needed parts are ten bucks on Amazon

There is a guy in red bank
that replaces ports for like $60. He was going to repair my GS2 (my last phone) but I just bought a phone with a cracked screen and swapped the board instead. PM me if you would like his number but he advertises on craigslist.

awesome, thanks for the info! the only real reason i want this port working is so i can root, so that wireless charging method isn't really for me, but thanks for suggestions guys!

Charging port repair
So what is the guys ph # for repairs? or do you have a link to a DIY video so I can see it and adventure myself into it.??
Thank you kindly

I plan to use this video to reference how to fix my gs3 should anything go wrong with my device in the future. I found this video on YouTube which explains disassembly and reassembly really well. Looks like the charging port is soldered to the main board.

Root w/o usb port (wireless adb maybe?)

so, i've been researching this all night and i want to get a straightforward answer. is there any way i can root my S3 without using the USB port? the port is busted and doesn't detect anything being plugged in (i have 3 batteries and an external charger, since it won't charge)
basically, i'm coming across some posts from the S2 explaining that you could root that one by simply flashing some SU files etc in recovery:
http://forum.xda-developers.com/showthread.php?t=1746794
can any of this be done with the S3? i was looking into wireless ADB as well, but you def. need root for that, despite the fact i also found someone on the S2 forums who apparnetly had wireless ADB working without root:
http://forum.xda-developers.com/showthread.php?t=1371326
i have no idea how he did it, because i def can't.
any thoughts? i'd love to root this thing and just keep it stock (just delete bloatware and make tweaks to stop the launcher redraw) and that's it..not even looking to throw custom roms on it yet.

Honestly I think you are SOL for the time being

well that's not good cmon con, i know you can figure something out lol

I was able to root by flashing an SU zip in CWM. However I was only able to flash CWM thanks to Casual. It wouldn't root me. But did let me install cWM. From there I booted into recovery and was rooted in seconds. With no USB though that makes things tricky. Not sure how you could get CWM on there then. I was able to root my Droid x purely using terminal emulator on the phone and pushing files from the SD card. But that was years ago and i think rooting is a bit different now since it looks like it gets symlinked.

Why don't you just get the phone replace as it is obviously defective?

First remove your battery and you may try to clean your usb plug on your phone by take a toothpick, needle etc.. and wrap a little piece of paper towel around it, soak with Windex or alcohol and scrub all the pins inside of the USB. This works wonder! second recommendation is to try another usb cable. Good luck.

Samsung would still fix it. I wouldn't live with it like that but to each his own

thanks for the responses guys! a few answers:
1.) i literally got this phone for $30 from a customer at my store who ruined it due to said tittysweat. no lie, the woman ran with it in her shirt, and sweat corroded the charge port. i SOMEHWAT fixed it with alch and Deoxit weeks ago, and it would BARELY charge (like maybe half a percent every 3 hours..ridiculous lol) but then after further cleaning, it completely died and doesn't work now.
2.) i've never once had insurance on my lines in all my 16 years with verizon, so i'm not adding it to make a claim, because it's gonna look fishy especially if they see 3 different phones on my acct within weeks
3.) has two TINY cracks in the corners of the phone screen, so i couldn't even get it replaced due to that as well
when i would plug it in when it barely charged, it would go between charging (ac) and just charging. so it was def messed up. i opened up the back to look at it, but i didn't take the entire phone apart yet.
i've got a replacement charge port (was 5 bucks on ebay), problem is i don't have a hot air soldering iron so i can't do it myself and don't have any repair guys near me.
just looking for basic ways to get rooted w/o having the usb port, but it seems to be futile
also for samsung to fix it, the turn around is like 2-4 weeks and i'm sure costs an arm and a leg..whereas i have a few members on here who i could send to and would cost less, and it would take a lot less time than samsung lol

infuse went swimming only workes when on charger

My son took his phone swimming, got it dried out and actually works but kills the battery very quickly, will stay on as long as its on the charger. I have tried a new battery (I have many) and its not the battery. any suggestions not able to get a new one under warranty.

First things - turn phone off, remove from charger, take battery out. Leave in this condition to avoid further damage which may occur when you apply power to a wet phone.
Also, getting started on the drying process quickly is somewhat important (but not so important that you should rush to do anything without finding some instructions first).

thanks but have been thru the drying and no power scenerio...... was over a week and a half ago.. did the batt pull and store in rice......

Sorry, I misunderstood. Yes that's a lot harder question.
You apparenlty have a high battery drain.
You've ruled out battery by swapping.
I guess before trying anything drastic, you might try typical approach to see if there is an application drawing battery (for example power tutor). That's a longshot since it would be unrelated to the water, but would be a shame to get intrusive if it's not required.
Other than than I guess you can try to have it cleaned to remove some contamination that may be causing like high-resistance short circuit causing a battery drain. I have no experience or recommendations on who might be able to do that. If trying yourself you might try inspecting accessible areas and disassembly to gain more access to the extent you feel comfortable. Possibly clean with compressed clean air or q-tips soaked in alchohol.... targeted cleaning if you can see corrosion, or longshot just clean everything in sight.... but that increases the risk level of something that is already risky (easy to damage things poking around inside your phone). If it were my phone I'd definitely be looking for someone else to do it rather than trying myself.
Sorry, not much help. Maybe someone else will chime in...

Sadly.... It is probably something on the board of the phone. If it only works when it is on the charger that means that no power is going from the battery to the motherboard. Same problem with a 3gs. Although that turned out to be a curoded chip on the battery itself, there is probably a bad part on the motherboard. You will most likely have to take it apart and look for water damage. Like curoded spots, and clean them of by CAREFULLY scraping the white off with a TOOTHPICK or something else soft and non metallic. That's all I can say, I've fixed a good many water damaged devices. But they all had on board battery's and the same part always went. The little chip controlling charging on the battery.
If you get it apart look around where the battery prongs are. Either there or maybe around the processor.

Did the phone get powered on straight of water???
If so corrosion is a possibility more that likely the currenent arched and damaged the circuit .
Does the phone heat up when running off or on the charger ???
Again if so then phone motherboard. Was damaged and the power circuit is causing the drain and allows for it to function on the plug because it bypasses the damage.
Just my humble opinion....
My only suggestion is if our handy with electronic find another on eBay and switch out mother board.

Others have recommended this product for cleaning gunk out of the buttons on Samsung phones. It also works to remove corrosion on electrical contacts - plastic safe, no residue. Might be worth a shot if other avenues don't pan out (available on Amazon and elsewhere):

That is for the suggestion.. had the phone apart, cleaned all the contacts.... phone boots up nicely, but totally shuts down when allowed to sleep N needs to be rebooted to start again.. also still killing the battery within minutes.... gonna get another mother board from eBay... thanks again for all the suggestions

[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

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?

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.
