Backlight no longer works after getting wet. - X Style (Pure) Q&A, Help & Troubleshooting

Hi guys on Monday my Moto X Style fell into a bucket of water ( I was ill) I promptly snatched it back out removed the case (Supcase Unicorn beatle). At first it was on and working fine and I wiped and shock the very small amount of water on it off. Then about 5 to ten minutes later the screen started to flicker, I turned it off and put it in a sealed bag of rice for 5 days. Upon taking it out on the 5th day the backlight isnt working at all. I've used light at an angle to test the screen and everything works fine, touch responds, no outlines etc, only the backlight. My question is, is there anyway of fixing this short of replacing the entire screen? I've heard people suggest cleaning the cables with 90% alcohol, is this a viable solution? I'm willing to try any feasable method before I get a new screen. Thanks in advance.

Well, you have to take it apart to clean cables and to replace the screen. So if you don't need the phone (you have a backup) I would take it apart and clean cables and see if that works. If it doesn't, leave it in pieces and order the screen and replace it when it gets to you.

My weird Herald experience...

<warning>may be a long post</warning>
Ok, some history first...
I bought my Herald 1 year ago, and after 3 months of proud ownership i dropped it into the toilet. (was just changing to my swimsuit in case you are wondering)...
After that underwater experience, the only kink was that the End button stopped functioning.
Fast forward to the present day. After opening my phone with the help of the service manual i found out that the fault was with the flex cable (the cable that has the keypad buttons, and connects the screen to the phone board)
So i hopped on Ebay and ordered a new cable, along with a new housing as my old one was full of dents, and had the parts delivered today.
I opened my happy ol' Herald, removed the screen protector (this is an important bit, just stay with me) and changed the cable and housing, hoping to transform it to almost-new condition.
After doing the transplant, and hoping that everything went fine, i closed everything and booted the phone up.
The End key functionality was restored, but the Touch Screen STOPPED WORKING!!!. It was registering some very strange positions and as i lifted the pen the cursor was yanking to the right, so i tried the first obvious thing of Align Screen. Since that wasn't registering ANY positions, i reopened the phone, reseated all the cables and still nothing was happening.....
I was at the brim of despair, after 5 hours of screwing, testing, unscrewing etc... and was leaving work... and just as i was packing everything up i picked up the old dirty and worn Screen Protector and tacked it on the screen (and since it was on my office the whole time it got very very dirty).
And lo and behold, everything worked with the screen protector on!!!
So this is the story....
Now, i have a couple of questions:
1) Anyone has a logical explanation about this??
2) I'm afraid to remove the screen protector in case i lose the touch screen again, so now i have a brand-new looking phone with a screen that looks like it was run over. What do you think will happen if i remove it?? (maybe open a poll on this)
3) I also yanked the keyboard (after discovering that its held with Glue on the casing). Now i have it tucked in place but it's not glued. Anyone now what glue is safe to use to make it stick in place ??

Water Damaged G1?

I spilled water on my phone they other night in my sleep. When I awoke the phone was still on but had frozen up. Upon a reboot it locked up on the splash screen and with a couple more tries it locked up on a black screen. Eventually I got it to boot to home but the touch screen isn't working and I'm getting force closes when I try to open any apps. I tried leaving it in uncooked rice to absorb the moisture overnight but I'm still getting the same problems. Anything I can do?
There are two very important rules when electrical equipment is soaked.
1: take the battery out as quickly as possible so it shuts down and doesn't short.
2: LEAVE IT OFF UNTIL COMPLETELY DRY! This can not be stressed enough. Having it turned on with water inside is like trying to kill yout phone intentionally.
I find the best way to dry it is to take of any covers, batteries, sd-cards, sim cards ad anything else you can easily dissasemble, and then leaving it in an oven on 40-50 degrees overnight. Electrical stove is kind of neccessary for this though, unless you have a gas stove with good temp adjustment.
If I bought a cracked LCD G1 and replaced the digitizer with the one on my broken phone (touch screen isn't working) it should be fine right? There are no actual electronics to the digitizer screen, right?

Theoretically, that should work. Haven't done it so I cant account for it.
However, how will that stop the FC's?
No, you misunderstood. I plan to buy a functional G1 with a cracked digitizer and use my old digitizer from the water damaged phone to fix it.
Nevermind, just found out the glass has some electrical parts to it and that's probably what I shorted out. Guess that's out.
I had my phone in my pocket when i went on a drunken creek walk. Long story short I pulled my battery had the same problems as you. So for my fix I wiped flashed a new rom then wipe again for good measure. Stopped force closes and works like a charm now.
read my post here for water damage if it happens again....

Well I did a Nand backup to no avail but I havn't tried a full wipe/format. Maybe I will give that a go and see if it helps. Did your touch screen also fail?
I'm currently using the G1 my brother dropped in a toilet. It accidentally turned on when he was removing the battery. It's really odd that the phone is working 100% at the moment.
Give it a few days before you rule it dead.
My sister dropped a RAZR in the toilet one day (Stoopit!) so my dad took it out (no pee in derp), hair dryer, rice, window, BAM!

The left side of my screen did not work for about 5 hours after I placed it in rice. Some say you need to keep it in rice for a full day or so. Basically take out the SD card, sim card, and battery and place the rest of the phone submerged in rice for at least 8 hours or so. Then try the phone.
BTW, my phone was acting sluggish ever since then so this morning, I did a factory wipe of the phone and things seem to be working normally. I also copied the SD contents and formated the card.

[Q] Please Help me troubleshoot this S4 problem!

Argh! i just spent the last 20 mins typing up a post and lost it! So lemme try this again...
Ok long story short, I goofed and dropped my s4 into a cup of coffee. It was submerged about 1/3 of the phone , on the top portion of the phone. I removed it immediately, pulled the battery and used a small vacuum to suck out as much of the liquid from the phone before i opened it up. Im pretty good with these kinda projects and have fixed many a phone over the years for friends who busted their screens etc. I hadnt been inside an S4 before this though, so i approached with caution. I used alcohol and a lint free microfiber brush to clean off anything that had coffee on it. All and all everything went pretty smoothly. After cleaning i put the phone in a bag of rice and silica gel for a few hours then put it back together and turned it on. It loaded up quick as usual, everything was pretty normal. But suddenly the screen would stop responding to my touches for a few seconds, and then start working again. So i turned it off, took it apart again and dug a lil deeper. I cleaned off all the contacts for the ribbons, and anything else that had any kinda sticky coffee residue on it. I put it back in the bag last last night and opened it up today and reassembled it. Turned it on , and like magic, everything was great! well 99% great. The phone is acting like it always has,and no more screen unresponsiveness or anything like that. All except for a small sliver of the top of the screen under the Samsung logo. Just a tiny sliver of the screen doesnt respond to my touches, which is a big pain in my butt because its just enough to not be able to swipe down the pulldown menu, and in some games i play, i cant click anything thats on the very edge of the screen in landscape mode. The screen looks normal, no signs of damage like ive seen in other devices when digitizers become damaged etc. Just that tiny little line of screen wont pick up touches.
I only went so far as to taking out the mobo and looking underneath that. I know i can go deeper, and would have to if i needed to replace the digitizer, but before i go through all that, i figured id seek the advice of the XDA Gurus first. Is there possibly anywhere else that i missed cleaning out the junk a that could be causing the problem in that area? Ive been very careful thus far and everything is working accordingly, hell the headphone jack even works still and that thing was full of coffee!! And all the other problems after the initial cleaning have gone away,and im left with this little line of screen that wont read my touches!! So i must have done something right so far! Im hoping that maybe i just overlooked another possible place to clean up any leftover junk and then will get full function of my screen again. if not, then i guess ill be ordering a new digitizer sometime soon.
Thanks for your time, anyone who reads this. I hope to hear some good news *crosses fingers* soon, and get my phone working properly again.
I'm impressed. Not just in your skills but with the build of the S4. Coffee is highly acidic. I once tore apart a keyboard that my wife spilled coffee on. The coffee etched the traces right off the P.C. board. If the S4 survived coffee on the inside workings they use a pretty good coating. It is possible they missed a spot and the coffee got it.

Can i revive this sucker?!

Hey all, i recently inherited a Nexus 7 (ME370T) that ive made a personal mission to fix! Let me give it some background..
Nexus 7 been left in the cupboard for 6 months after a smashed screen.
I rcv said Nexus as person thinks it dead and has given up with it.
I decided to replace the screen so ordered one from ebay
Dismantled the nexus 7 failry easily, removed the lcd from the frame, cleaned the frame up and removed most of the adhesive then applied some double sided tape and placed the screen back onto the bezel.
Carefully resat the display on the motherboard with frame. All screws back in and and cables attached (double checked connections just to be safe).
Went to boot but as battery has been left to die it took around half an hour to give it some life (actually took 8 hours to fully charge)
Loaded up ok, albiet it took quite some time to boot past the X screen.
Booted up but then touch seriously slow and lagging, a good 30 seconds behind. Tried all kinds of possible fixes from the tie wrap to reseating the digitiser cable to soft reset and still not working.
So i bit the bullet and decided to reset to factory settings....
But NO, bloody thing still refuses to have a working touch screen!!
Running out of options now but im willing to try anything... has anyone got any advice or is it time to concede defeat and give this thing a running kick?!

Water Damage: Screen not working

Hi all,
last week we had a really heavy rain and I was outside. As a precaution I put my phone out of my front pocket into my backpack only to realize that the backpack was filled with water when I came home.
The phone was swimming in water but still on and working but I had no equipment to open up the phone (damn T3) so I had to leave it powered on and put it in rice over night.
The next day when I tried to boot the phone the screen stayed off and you could see the liquid between the lcd and the digitizer.
I went to a local repair shop and they opened up the phone. I let it dry for some more days but the problem with the display remains.
I washed out the mainboards with iso and cleaned all corrosion I could see with a toothbrush but after replacing the screen it looks like the issue remains.
The phone makes sounds like it is working and giving notifications but the screen is just dead.
Do you have another Idead what I could do or do I need a new phone?
Thanks
crckmc
I am in the exact same boat (almost literally)
I dropped mine into the toilet (how cliche) and it also worked for a few minutes, then eventually the screen went black. I see nobody responded to you here, may I ask what have you ended up doing with it? Replace screen? Get a new phone?
