[Q] Screen VERY Dark After Accident But NOT Black - Phone Still Usable - Need Help - General Questions and Answers

Hey guys,
I have a Droid Incredible 2 that I dropped in a cup of water for a small amount of time. I let it dry, and when I turned it on the screen was very dark. There was still an image, but it was almost impossible to see. The phone still works, it will text and call, but it is almost impossible to see things.
So, I replaced the screen with a new unit, confidant that it was the problem. But, of course, that did not fix it. I am out of ideas, so I am hoping someone here can chime in! (My question is what else could be the cause?)
Thanks for any help!

If your phone is in uder warranty replace it
Sent from my GT-S5360 using xda app-developers app

Did you replace the actual LCD screen or just the touch panel (piece of glass on the front of the phone)?
If you did replace the LCD that sounds like the backlight isn't turning on. This could be for a variety of reasons, but probably something that powers the backlight on the phone's circuit board got damaged by the water since the light itself should be part of the screen assembly. You could try removing the battery and leaving it in a bag of dry rice or those dessicant packets (things that say "Silica Gel - Do Not Eat") that come in shoes, electronics, etc. for a few days and see if maybe it's just some more water that needs to dry out, but if that doesn't help you're probably looking at a circuit board replacement or buying a new phone like andromaki suggested. It also wouldn't hurt to take the phone apart again and check to make sure you plugged in all the cables that come out of the screen and none are upside down/not in the connector all the way.
* Yes, I'm specifying dry rice for a reason. I once advised someone to stick a phone that got dropped in the sink into a container with some rice, and they put it in some leftover fried rice from Chinese take out, which did not help matters.

I agree with lroop. "Very dark" sounds like the backlight or backlight inverter (power supply) might be bad. I would assume that the backlight and inverter would all be built into the display, but that may not be the case. If the inverter is separate from the LCD and it has gone bad then switching the display would not fix the problem.

Possibly water damaged Captivate half-working

I may have possibly water damaged my Captivate last night. It was in my pocket when water spilled on my lap, and I didn't immediately take it out. Very stupid of me. The USB port was open so I'm thinking liquid may have gotten into there... Also, there were water beads on the inside of the camera lens.
My recourse was to take it apart and try to let it dry out. Initially it wouldn't do anything upon being plugged in to the charger, so naturally I thought it was bricked. I've let it sit all day on a dry window sill next to the radiator. After putting the battery back in and plugging it in a little bit ago, the phone surprisingly booted up. Here's where I'm at now:
The phone boots normally, however if I plug it in to the charger I get an error stating Battery Temperature too high or something, so charging is paused. Does anybody know what this indicates?
Secondly, after being on for a minute or so, the screen gets screwy. Dark transparent overlays start flashing over everything and it gets unresponsive... I haven't left it on like this long b/c I was afraid something worse would happen - I usually rip the battery out of the back to shut it off.
My phones currently pulled apart and drying in the window sill. Whatever water got on/in it is not visibly there, however I understand some parts might still be wet.
Any advice? Also, I believe the water indicator on the battery and near the pins where the battery dock in the phone are both fine. They're white squares and haven't changed color. Any chance there are other indicators?
The phone isn't insured and I bought it back in August. Would warranty possibly cover this or will they know about the water damage?

well you want to put in rice, so that the moisture is gone
rice it for sure. but warranty WILL not cover it UNLESS the tabs on the battery and phone are white (It might not have gotten wet if it was in your pocket)
if they are still white, or if your phone is white and battery red (then buy another battery) and get to the store and tell them you don't know what is wrong with it. The only indication that it is water damaged is if it is red and those tags are notoriously faulty so you could always argue your way through it if you have an account in good standing.
best of luck.
I know someone who "claimed' that insurance was supposed to be added to the phone when he got it and noticed that the person didn't do it properly (the guy was new so it helped his cause) and the manager of the cor store told him that they'd do a courtesy replacement and charged him the 125$ for a new device.
you could go that route should you need too...
I don't have access to rice at the moment... Would it do any good even if I absolutely can see no water anywhere in/on the phone?
Am I doing my phone any harm/potential harm by trying to turn it on every once in a while, or should I just let it be for a few days?
Take the phone apart and focus the strongest fan you have on it over night. It's probably best to not turn it on for awhile. Maybe if you focus a blow drier on it for perhaps several hours, air will find flow through the small openings within the case.
You may not be able to dry some parts of it unless you do a complete dismantle, but that may require special tools
Consider shipping it to get repaired only as a last resort, as I've read some bad reports about that.
Rice or some other dessicant is the way to go - it will pull moisture out. Also, turning it on (even putting the battery in) is bad - you are powering circuits and possibly creating shorts where water is present. You may have already done permanent damage.
If you get electronics wet, the best course of action is to remove the battery and put it in a bag of rice for a few days.
Now that You have the phone apart get an alcohol pad and gentley scrub the main board. Sometimes when liquid touches the main board you will get a white looking residue. If you see anything like that simply wipe it off. I dropped my phone into a trash can at a very popular teriyaki restaurant here in Las Vegas my phone was submerged into a deep bath of teriyaki sauce. I quickly pulled the phone from the can and wiped it down vigorously. I was excited to see that it was initially working unfortunately this was not the case by the time I got home. The phone would not turn on for a whole week, until I decided that I was going to open her up. I found a tutorial on line describing a complete break down of the captivate. Upon opening it I found I was able to see exactly where the teriyaki had interacted with the electronics due to the remnants of an oxidized white film that was present on various parts of the main board. I grabbed a alcohol pad out of my first aid kit and began wiping it down to remove all of the white stuff,put the phone back together and to my surprise it turned on. Hope this helps!
Thanks for the info guys.
How would I go about getting to the "main board"? Taking out the battery and looking inside it only reveals where the battery connects, where the SD card and sim cards can go... I'm assuming if I remove the little screws around that fixture I can get to the "main board"?
I think I can see some minor corrosion around where the sim card connects, but I think I *should* be able to clean that with some alcohol.
The phone seems to be working fine (I've yet to put my SIM back in it, though, so no idea if the corrosion around there is affecting it at all). I just booted it up and was able to get on the web (wifi), run apps, everything just fine. Didn't get the flashy screens I mentioned earlier. However, if I plug in the USB charger, it still gives me the temperature error. I didn't keep it plugged in, however it did make me realize something:
The errors I was getting before, where the screen went all wacky, only happened if the phone was plugged in to the wall. Is it possible my battery is busted, or do you think the USB charger is busted? Remember that port was open when it happened.
Any thoughts? New battery? Or do you think I won't be able to charge the phone via USB charger any more?

yes you are, because if there is water or moisture internal, it can short circuit, also rice will help dry up the phone completely

If you've never taken apart a smart phone before, and reading your first question, I'm going to assume that's the case, then I strongly advise you not attempt it unless you are willing to either A) buy a replacement after you break it or B) invest time/money into repairing mistakes you've made. This phone is not as difficult to disassemble as some, but I wouldn't want to break that $150 amoled screen.
No, removing the screws will not simply get you to the mainboard. It's more complicated and nuanced than that.
I'm a new user so I can't post the link but if you google Tech Republic Captivate tear down [/B]there is a website that will show you step by step how take the phone apart. There are two screws under the clip you pull down to take the back cover off. Be careful when pulling it back to expose the screws. I tugged on it pretty hard with no problems, but I imagine it could be broken if you pull too hard. Good Luck! It's actually really easy to take apart and the various ribbon connectors on the main board are really easy to unplug and plug back in after cleaning it.
So what do you guys think I should do if I'm still getting the battery error with the thermometer and yellow caution sign? Buy a new battery? Or do you think its the USB jack? Has anybody seen this before - the battery was working fine as long as it was not charging.
I'm trying to decide between a) buying a new battery, or b) buying a wall-mounted battery charger since the USB won't charge the phone.
Anybody have any experience?

I think you need to be careful about who you encourage to dissect their device. This guy asked how to get to the mainboard. Clearly, he hasn't opened a smart phone before. Telling him it's "actually really easy" is disingenuous at best. Performing smart phone repairs properly requires experience. I'm certainly not suggesting that noobs not try to fix their phones, only that they are made fully aware of the risks.
My Captivate was fully submerged in dirty water. I followed some instructions online and it's been working fine for over a month now. If your water-detection stickers are already red anyway, and rice isn't working, I recommend it:
1) Remove battery, SIM card, SD card
2) Submerge in a bowl of distilled water and gently agitate. This helps clean the insides. Distilled water (not spring water) does not conduct electricity.
3) Next, submerge in a bowl of high-quality rubbing alcohol (~95% pure) and gently agitate. Rubbing alcohol displaces water, removes corrosion, and evaporates quickly. (It's also flammable, so have good ventilation and no open flames nearby)
4) Leave it out to dry for two days or until it no longer smells of alcohol.
BTW I wouldn't dry it too close to a radiator, the heat may damage it.

Not really. Once the screws are removed..including the two hidden by the battery cover lock slider...you can carefully pry the cover apart using your fingernail to get to the the internals. I have done it several times and am no expert by any means. Just don't yank like you are opening a present on Christmas morning.
Although I am mystified by the op stating they have no access to rice?! That should always be the second thing one does after a moisture incident...right after pulling the battery and sim. I guess in this case a trip to the store with a couple bucks may have pushed that to step three though..

[Q] A "washed" through laundry HTC Diamond

Hello,
by a rediculous accident I forgot my HTC Diamond in the pocket of my jeans when running the laundry :-(
Afterwards, I opened the cover, took out the battery and let the phone dry out for 2 days. Now I've put it back together, and connected it to the charger. The "ring" is flashing, so the battery is charging but the phone itself is not starting and the display remains completely black, not even the vibration kick on starting...
Is there anything I could do? Or perhaps there is a chance to get out some photos I have shot earlier, would also be something...
ive heard that taking apart your phone and leaving the parts in rice can help (because the rice absorbs moisture)
Off topic:
I read one Desire went through a washing sequence in a washing machine in Desire spesific forum and now this?
Is this a new hobby? I mean... washing smartphone

If the photos are on your micro sd card, you may be able to plug that into an adapter and plug it into your PC and gain access to them that way. Just be sure that micro sd card is thoroughly dry before doing so.
WORKING !!!
Hello,
thanks for the replies... This morning the phone booted!!! I was able to download the photos!!! But the screen has stains, obviously the remaining water.
PLEASE advise on how to dry that thing completely !!!
I think that I'm gonna pass on the rice thing.
@aaa - YOU ARE A JUNKA$$ !!! You think that's really funny?!? Especially when I'm currently TIGHT on budget and need the money for other things and the next phone is planned no earlier than Christmas... I'm hesitating whether you're a real human being...
You can dry it completely in an oven for three hours at thirty degrees or so. I've done this three times. If you have a fan forced oven, just turn the fans on, that'll be enough.
A safer way (if you can obtain it) is to leave the phone for 24 hours in a bowl of dessicant silica gel. You'll often get a small packet of silica gel when buying new electronics or other moisture-affected things. That small packet is enough, just put it in an airtight bag and leave it for 24 hours.
The next step would be disassembly and a thorough swabbing with denatured alcohol, but that's pretty extreme and only needed when the device isn't booting.
Some LCDs are hard to get moisture out of, some are not. Leaving the phone with the silica gel for longer will have a better effect. As the previous poster mentioned, rice also works (quite well), but takes longer than silica.
Good luck with it!
Another thin that will absorb moisture is common table salt. Take the phone apart very carefully. Remove battery first, make sure you're grounded as well.
Hello everybody.
thanks a lot for the numerous advices...
Unfortunately, I have more to report...
The phone dried out and booted 2 or 3 days later, as I said. The stains on the display disappeared as by magic one day later.
Everything was fine for a week until I launched the camera 2 days ago. The backlight of the display went off and came back only after removing the batter for 15 minutes.
Now the backlight is going off pretty often, sometimes it requires to remove the battery 1-2 times before it starts working again and yesterday it happened that it got activated again when I got a call...
Any ideas please?
And also the phone keeps overheating from time to time without real load (GPS or wi-fi) which dries out the battery. But I had this problem also before the laundry
Sounds like that moisture in the LCD unit left a bit of residue and is shorting the backlight somewhere.
Only option there would be to disassemble and swab the LCD boards and cables/connectors with denatured alcohol.
Alternatively, a new LCD unit should fix the problem if it persists, just make sure you alcohol swab the connectors before plugging them back in
Someone also mentioned drying out in salt before. While that does work, salt is extremely corrosive on solder and SMCs, so I wouldn't recommend that route.
i heard hair dryers are the bomb at the screen moisture, just take off all that you can and blow dry it.
I just don't understand your refusal on using white rice. It have saved countless phones.
Uncooked white rice is VERY mosture negative. Just put layer of rice, put your phone on it, cover it completely with white rice, seal it in. Ziploc could work too.
In a day or two your partially dry phone will be bone-dry. If it was soaked still you could first try to shake out water as much as can, soak it in distilled water to remove minerals, then white rice it for 3 to 5 days.
I had this problem with my Touch Diamond. Everything worked, but while i was trying to dry it I broke one of the battery "hinges" but the phone still worked after except only with black screen. The best thing to do probably is just leave it for a couple of days and hopefully your phone will be back!

exactly what ive said. ive read everywhere that rice is one of the best solutions out there
Like was said before you most likely have some corrosion on a few contacts, if you have about 6 bucks you can spare you can get residue free contact cleaner in an aerosol at radio shack or any electronics store and save yourself having to scrub each contact and connector. Just tear the phone down down spray all the contacts and connectors with contact cleaner let it sit for a few then spray it down with air duster to get any thats get under the resistors, in the connectors, etc that hasn't dried; let it sit till you're positive everythings dry and put it back together. Does the same thing as alcohol just alot less scrubbing.

Hello,
thanks for narrowing the problem down.
But for me it looks like something different, because:
1) I have been using the phone for 1 week without any problems and it got screwed after I've launched the camera app for the first time
2) The backlight works when I power on the phone. But its stop is event-triggered, like when I launch the sound or video player or when I get a call... Similar events would trigger the backlight back on.
Perhaps reflashing the software could fix that?
I went to a shop today and put another battery. The phone booted, anyway without any backlight, twice...
At least the device is still alive.
There probably was a tiny water bubble and it messed with phone when you turned camera on.

Either that or a short in the cameras circuit from corrosion, either way i'd pull it apart before it gets worse and check it out.

[Q] Nexus S [i9020] Possible Water Damage

Hello all,
My Nexus S i9020 running Android 4.0.4 has run into a spot of bother!
As a result of leaving my phone on the windowsill while I was having a shower, condensation seeped into the phone, causing it to malfunction, and eventually die. The phone will not turn on/off and the computer cannot recgonise the phone when I lug it into the USB port. The phone however, does get warm when I leave it charging for 20-30mins. I have tried the bag of rice trick and that didn't work. I have also taken the phone apart and cleaned it but that didn't work either.
I sent it away to a phone repair company to see if they could do anything and they said it was a waste of time as there was mildew growing on the circuit board. I said I would post this anyway, incase anyone might have an idea on how I could bring back my beloved phone, and also to warn people not to leave their devices in the bathroom when having a shower!
Thanks, Jake
Take the phone apart use a hairdryer and dry the mobo+screen for quite some time (20minutes++ depends) at the maximum heat be careful on the screen cause u can damage it from excess heat i can't tell exactly what is degree is ok for the screen as i do it by "feel' (no i don't touch it to understand if the heat is enough) . If that doesn't work then probably the ic chip is damaged or something else ;P
As for myself i never had a phone die from water damage i have dipped a nexus s in water (don't ask why i'm crazy enough) the battery didn't die completely but was unusable, the screen had marks after the water was removed, but the motherboard was fully functional. (take notice i have dipped 2 nexus s screens in water they always leave marks when the water is removed always !)
Worst i had was a bb9000 which i got into the shower with it (i was drunk) next morning the phone was on and completely soaked, motherboard survived, screen survived but battery died and the key membrane needed to be replaced

Repairing Damaged Screen on OnePlus One

Around May 2016, I jumped into a pool with my OPO in my pocket. About 10 seconds afterwards I realized what I had done, and pull the phone out of my pocket. The screen wouldn't turn back on, and it started continuously buzzing. Eventually it stopped and I tried to dry it off best I could. Blowing out what water I could and stupidly purchased a bag of rice I kept it submerged in for awhile. Nothing worked of course.
Eventually I took it apart. The battery glue was so sticky, the battery started to distort as I tried to pry it away from the body of the phone. I figured at that point, it was pretty much destroyed. But I took it apart and used some alcohol to clean up some of the parts. At that point I just decided to order a new phone since I already had it for about 2 years anyway.
But now I want to get it working again to recovery some data and images.
I purchased a replacement battery, soaked the main board in alcohol, cleaned up some of the connectors, etc. Reassembled it, and to my surprise it worked again! Well, except the display. But the digitizer still worked, the capacitive buttons worked, and I could hear sound even. Seemingly everything worked but the display. I can even see the backlight come on sometimes but with no actual picture and some noticeable water marks. I was even able to fiddle around with the digitizer, unlock the phone, connect it via USB, and recover some of what I wanted. However, I was hoping to get the display working so I could recover additional data.
So I purchase a screen assembly (display, digitizer, and front body) off ebay. But same problem, I see the backlight come on sometimes, but no picture. I tried cleaning all the contacts again and re-seating them several times to ensure all connections were okay. Still, no picture on the display.
So I thought maybe I could have ended up with a bad display off eBay. So I ordered another. Still the same issue.
What could I do? Is there anything in particular I should try that might help? Is it the daughter board maybe? That might be easy enough to replace.

Since the whole thing involves water,there might be several parts which are damaged. I suggest get your device checked from a professional repair shop.
I was hoping I can learn more about what a professional repair shop might do to diagnose the problem.

Just toss it away after transferring the files.
It's not worth the hassle, trust me.

Do you have any advice as to what my next steps would be after having tried two replacement screens. Literally everything works on the phone except the screen doesn't light up. Even the digitizer works. Well I can see the backlight come on sometimes, but no pixels. I've cleaned an re-cleaned the connectors many times using 91% isopropyl alcohol.
Is there any particular resistance or continuity I can check that might indicate what component is bad? Information about the pinouts somewhere?
Maybe there's another part of XDA or another forum that goes more in-depth into smartphone repair? If anyone has any recommendations, I'd greatly appreciate it.

[HELP!] Photon Q display suddenly faulty

So I was using my Photon Q as usual, had a sick new CM11 install I was playing with for the last week or so, and all was good. I pulled it out of my pocket before I took a shower to check the time and nothing. The keyboard would open when slid out, and it even buzzed when i force restarted it. The backlight turns on for a few seconds when turning it on but other than that, no dice, it turns right off. HDMI out is doing nothing either. It is detected by my computer and otherwise acts like everything is normal. I didn't drop it, it was just in my pocket and a little warm, but it was really just the usual "pocket" warmth. What the **** happened? I can't even tear it open to check because one of the inner screws is stripped : (
EDIT: Can't boot into fastboot or anything manually, connections look good, this is so annoyingly random, and this is the first motorola device to just fail on me without reason...
EDIT EDIT: Died in my drawer last night, plugged it in and the green LED turned on, but shortly after it turned off and and now I am back to exactly where I was before.
Answer: So As you can see from the replies below I am most likely dealing with a broken flex cable to the front panel. I am gonna save up for an un-modded replacement and just swap motherboards. I gutted my current Photon Q and am storing all the parts in bubble wrap, with the motherboard delicately wrapped in paper (less friction, it's sim modded and those exposed copper wires just seem so fragile)
@CornholioGSM I ping you because you are the main Photon Q guys and one of the few still really active, you have seen this phone inside out, any ideas???
EDIT: I checked all the connection after tearing away plastic, it's all good looking. I don't understand wtf happened...
It's usually an issue with the flex (ribbon) cable... all I can say is make very sure that cable is still properly connected.
Good luck.
One of my Photons had a dead display while another had an apparently dead display because the broken flat cable.
Hard to say which one is the culprit w/o a close visual inspection to the flat cable, and even in that case a flat cable apparently in good shape can have one or more broken lines.
BTW a LCD panel can theoretically last for decades, while the cable has a finite number of sliding operations, so the latter is more likely to be the culprit.
Possibly your best option is to get a cheap unmodded PQ from the USA, and replace the whole screen assembly w/o further investigations. Less risk to damage something, way less time needed for the transplant, and possibly even the cheaper option.

Thanks, I'll probably use whatever money I get from my Nexus 5 sale for a replacement Photon Q (un modded). Mine is beat up from a recent camping trip, scratches all over, I need this anyway. Worst case I have myself a sweet new music player. For now I am using a Galaxy Nexus, which I love, but I miss the Sailfish OS support.
