Repair Xperia LCD screen by freezing it - XPERIA X1 General

I am posting it here since I only experienced this with Xperia but I guess it should work with any LCD.
Two days ago I sat on my Xperia X1, literally- Result a distressed LCD with a huge white spot covering nearly 3/4 of the screen. There was also a burn in of the today screen. The touch screen worked, but due to the whitening and the burn in, it was unusable.
Bummer I thought. Then something told to me by a LCD technician came to mind.
Here is what I did;
1. poppied out the battery
2. Placed the xperia in the freezer (i an not sure what the temp was but i had set it to -60 deg Cel (thats the min my fridge can give)
3. Let the unit freeze for 18 hours
4. Took out the unit
5. brushed off the ice
6. wrapped it in paper towel and let it sit for several hours to warm up to room temperature
7. after several hours used a hair dryer to gently blow on the set
8. popped in the battery
9. switched it on
Problem solved- no white spot, no burn in, just plain bright wvga goodness again.
Note- steps 6-7 are for getting rid of any condensation moisture that may accumulate on the cold phone. Do please make sure your phone is dry of any condensation on inner circuits before powering up- you may damage it further.
Do this at your own risk. I won't be responsible for any damage to the set, blow out or nuclear detonations.

I love it! The Xperia has some sort of robotic immune system!

Likely Death to my G1

today was a horrible day...
apparently leaving your g1 in your pants while they are in the wash doesnt work so well.
does not power on
anyone have any idea what can be done to bring it back or is it most likely fried
and if it is done then does anyone want to buy it as is?
I guess this is an excuse to get a g2
*UPDATE*
I guess no G2 for me just yet.
My phone works great now. Did not do anything special. Did disassemble the phone though so I can wipe down any residue i saw on main components such as the keyboard.
My advice to anyone that has this misfortune is not to rush things. I think i turned my phone on 2 days too early but I got lucky and it did not affect my phone. I figured this out because there was a lot of visible moisture in the screen when the backlight turned on. The keyboard was not functioning correctly either.
I did leave it in rice for about 36 hours but I do not really think that did much as far as the drying process goes. Best thing to do is go to a hardware store and pick up a torx driver set(mine was $4 at Home Depot and it was 36 piece set including torx philips hex slotted and pozi) open up the phone *be careful* of course and let it air dry for 3-4 days (not absolutely necessary to take apart the entire screen but if you feel comfortable go ahead). While it was open I wiped down the main board and the keyboard. I did not take apart the screen because I just did not want to take any other risks(mostly because i knew the screen worked) even though there was moisture, I knew it would eventually dry out. But the key to all of this was patience(I know its tough to go 3-4 days without your baby).
the link for the service manual is http://mikechannon.net/PDF Manuals/HTC Dream SM (A04).pdf
Most of the time, phones can live through the washer and live. You MUST take out the battery and do NOT attempt to turn it on for atleast 48 hours, as you will likely short out the phone. Put the phone in a big bag of rice to let it soak up the water, also use a blowdryer to help dry the phone out. However, your warranty is now void, and there likely will be some remnants of water within your screen.
Yep! worst thing you can do is turn that thing on (or try) before its dry.
my g1 hasnt had a bath but other phones have (none with touch screens) and i take as much apart as possible and leave it that way till the waters gone (then like 4 more days just to me sure )
artifical drying sources reccomended (dont get too hot!!!)
I have had it in rice for about 24 hours now and its sitting on top of my dvr because it gives off a little heat so it should help the process.
just remembered that i didnt remove the sd card...
i was thinking that since it was in the washer with detergent, shouldnt i have just removed the battery and try to clean it in some type of solution...
I have read about a alcohol solutions but kind of scared and i just noticed that there is condensation around the edges of the screen
I'd say take it apart, Blow dry what you can, leave the pieces in a warm area for a couple hours, and then try putting it back together and turning it on.
anybody know how sensitive the screen is because i want to try and blow some heat on it but not sure if it will damage it

good point but im on att network using the g1 unlocked...
plus i rather not cheat my way out of it because this is my own fault
good news and bad news...
first of all it powers on and boots fine. Secondly the screen seems to be working perfectly (touch and all)
bad news i might have turned it on too early because screen still had noticeable water spots all over it. The keyboard also just spews random letters and commands (ie one of the letters controls the volume)
other good news 1.5 has onscreen keyboard
anyone have any advice on how to go about fixing the keyboard?
Advise for fixing the keyboard: take it apart and clean it.
ok well im taking it apart to clean it out and i see some residue but what should i use?
microfiber cloth?
cleaned out as much as i could but seems like the menu button is now acting up while the keyboard is still messed up
Aside from parts made of paper, parts with thin films (like the lcd), speakers, batteries, or fine parts that are difficult to dry, you can do a very neat job with 99% iso alcohol followed by deionized (aka distilled) water. This includes most (but not all) plastic casing, buttons, pcb boards, etc. Follow up with a hair blowdryer set on low heat (or if you have an electric heatgun, even better).
Get a semi-shallow dish, fill it with the solvent, submerge the part and scrub it lightly with a soft toothbrush. (probably don't scrub for polished surfaces like the exterior casing). Then directly rinse it under a stream of the deionized water. Finally, clean the dish out, fill it with the di water and scrub with the brush.
^ almost exactly what I did to recover a "dead" water soaked phone. Worked great, and learned a lot about how the phone is built
couldnt find 99% near by but got 91% which im assuming should work...
is it ok if i use bottled water(kirkland)?
oh and the spots on the screen are still there (light and dark areas)
thanks for the help guys

I bought my 99% iso from Safeway. It comes in a 16oz container. Look for it in the medical supplies aisles. Don't use bottled spring/mineral water, as that contains... minerals. You need buy deionized (also referred to as distilled) water. Distilled water contains a significantly lower amount of mineral ion, which for the purpose of cleaning electronics would be considered contaminants.
Do the spots appear to be blotches of moisture? Perhaps there is fluid trapped between the various layers of the lcd.
ok ill go check out safeway tomorrow morning. thanks for clearing up the water thing.
it looks like its moisture because after leaving it off for about 5 or 6 more hours i saw a few spots fade a little bit.
I will take the screen apart tomorrow as well. Any special instructions on handling the screen or even cleaning it?
You might want to search for the service manual for the G1. It details a complete teardown and rebuild of the dream hardware.
some sort of a miracle just occured because my phone is not acting up at all anymore and i didnt even clean it with the alcohol solution yet.
Just woke up in the morning and turned on the phone and worked perfectly, with absolutely no problem with the keyboard(except that i think i forgot a screw and a few keys are a little loose) everything works fine.
only problem is that the screen still has what looks like condensation.
but the blotches in the screen seem to be slowly fading. Gonna pop it open right now and leave it out overnight.
thanks for the help
oh and the manual has a few mistakes in it as far as procedure goes but any person with common sense should be able to get past those
Damn, thats rough man. I dropped both my old phones in the toilet(damn you superbowl, damn you!!!)and both of them worked after taking them apart and drying them off but never really worked 100% the same...
Just a note too, those were non-touch screen phones.
Best of luck.

Just dropped my HD2 down the toilet

I immediately removed it from the water, and desperately tried to remove the back case to remove the battery (its quite hard when the phone is wet) i got there eventually though.
The screen was flickering whilst the phone was still on, and the water sensitive stickers on the battery and phone are both pink. I've blow dried it for about 10 minutes haven't tried to start it back up yet.... any suggestions?

DON'T start it for a few days. Put it in a warm place, leave it to dry for 48-72 hours and pray it works when you turn it on.
yeah just be patient and wait about 3-4 days to dry. but do not put it under direct sunlight
....and wash your hands
Try to put into bag with rice, and leave for couple of days...

put it in a bag of rice or leave out in the open?!?
put your phone into rice and keep bag closed
Basically you just need to make sure you dry it out thoroughly. Don't try to rush this process in a few hours. All the posts about leaving it somewhere warm (like an airing cupboard) are correct. Don't put it on top of a radiator or hot pipe, or in the sun as already suggested. The idea of putting it in a bag of rice is to help draw the moisture out. Never tried this method myself.... You really must be patient with this - managed to save my Touch Pro that got soaked in the rain last year....
okay so i've put the phone the battery and the sim on top of some rice in a bad behind my tv in my bedroom
rice like the others said or if you are a cigar person (or know someone who is) place it in an acrylic humidor w/ humidification beans.......I resurrected a M$ ZUNE my wife dropped in a rain puddle by doing this in my humidor
man, this reminds me of the time I dropped my phone in a bucket of puke from a heavy night. Still worked after I dried and cleaned it up.
"DON'T start it for a few days."
yup ..is correct wait until dry ... "rice" are good for absorb humilities ..
but If I not wrong ..after dry .the speaker of the phone will change ..just like my tytn II drop into "wash floor water", it still can use .. but the speaker sound change ...
Οh man , really bad luck..
hope it goes ok but be patient and let it dry manually !!!
my wife washed my cellphone once (left in pocket after heavy night of drinking). Took the battery out, let it sit on a counter for about a week. Phone recovered though it took the screen a while for the colors to all show properly.
I have read where people put their oven on warm and leave it overnight. I don't think this will hurt the phone since their won't be a power source in it.
Dropped in a sink with the tap running!
I dried it out under a hand dryer, then powered it up straight away. In hindsight this was pretty stupid, but it booted up ok. The only problem being the NAVPANEL would randomly appear and require a reboot. The next day that problem had gone away, and was replaced with a new problem - the Volume down button being jammed on! Also the battery life was reduced to about 10 hours. After a further 48 hours and a blast with compressed air (around the volume buttons) the phone has returned to 100% normal use - even the battery life is getting better, now upto about 36-42 hrs..... but I have bought a replacement for that anyway!!
Can't believe how lucky I was!
[Edit: Just saw you fixed it. Bravo! I'll leave this here anyway...]
Rice is good, unless you have any silica gel kicking about, the stuff you get in electronic packaging in the little paper bags/sachets that say "do not eat".
But yes, definately don't do what the majority do...
"I just turned it on to see if it would work..."
"You turned your phone/laptop on while it was wet... to see if it would work?"
"Yeah... why?"
*facepalm*
Happens about once a week in the PC store I work at. You could also try stripping it after it's dried and going over it with a carbon pen to remove any corrosion/residue.
After removing the battery, SIM, and MicroSD and gently removing any surface water.
One trick I found is to put a phone in the path of hot dry air for 30 minutes to a couple of hours. A clothes dryer vent works wonderfully for this since its temperature controlled (and timed) to keep from destroying the fabric in your clothes, and hot enough to allow water to evaporate. If you have access to your dryer vent hose, unhook it and rest it on top of the dryer and put your phone in the path (at least 4 to 6" from the opening). It's worked for 2 phones so far. One being my wife's Motorola, and one my Touchpro. If you have a dryer with an insert for shoes, you could use that as well, although I would put the phone on something to keep it from vibrating off.
You could use a hair dryer but keep in mind that hair dryers are not designed to be run continuously and the temperature is not technically regulated.
The trick is to get the temperature of the whole phone up to about 130 to 140 degrees and the water will evaporate. I would avoid shaking the water out of the phone or using pressureized air since that will push water into the delicate connectors, keypad matrix, screen, etc.
Let me give you a more scientific approach to your problem, i will try to explain as better as i can since english aint my primary language.
After you drop it in the water, your phone will never be the same for couple of reasons. First of all, when the water will dry, salt will "sit" on the connections and the weldings of the connectors, and that will slowly but steadily eat them. My saying is : " Never trust a phone that was dropped into water/coffee ". For you to be sure of your phone you need to strip it, and clean it with a spray for electrical appliances. Now there are 2 types of those sprays, one with oil and one with no oil in it. For your thing you need the NO-OIL one. Thats to make sure you wont get a loose joint and eventually your phone wont get broken.
If you dont feel like opening your phone and you dont feel comfortable with it, just ignore my post and just dry it out. What is 100% sure is that at some point it will break down, it depends on when though, from hardware to hardware.
Just my 2 cents.
Any time I get anything wet I IMMEDIATELY remove the battery, then I remove anything else I can from it: Sim Card, Memory Cards, etc. I don't like the rice idea because rice ALWAYS ends up stuck somewhere inside. I prefer setting my phone on some foil out in the sun for a bit (provided it's not too hot out) or just leaving it somewhere where it's warm to dry out. DO NOT BY ANY MEANS put the battery back in or turn it on until it is COMPLETELY dry. A minimum of a day if you even want to begin to chance it. If it was dropped in something other than relatively clean fresh water, I would keep everything out of it (battery, sim, memory cards, etc.) and dip it in a cup of distilled water a few times to clean any particles off, then let it dry again completely before turning it on. Just because an electronic gets wet, doesn't mean it won't work. The only way to kill it really is if you power it back on or the battery shorts it.
I went swimming at the lake with my old Nokia 5310 for 10 minutes before remembering it was in my pocket, I immediately took everything out when I remembered and left it in the sun for 8 hours and it worked fine for a year after until I threw it into a wall as hard as I could due to a frustrating girlfriend haha
U may have problems in the future... Since it was submerged in water some components will begin to rust... I suggest u take it to a mobile service shop so they can tell u what to do, or maybe they can fix it...

[Solved] Water in SLCD

Did anyone already open the Desire HD?
I followed a youtube instruction how to apply the screen protection, with some drops of water. Well, being more careful than in the video by using a towel to suck off rinsing water instead of a plastic wiper to get the foil onto the screen did not help.
Phone is dry and works without any limitations, except for the usual VERY annoying 'watermarks'
I am sure the display 'only' needs some cleaning in between if possible. Did anyone ever try that? I found HowTos for Desire, but none for DHD.
Ouch! Are you saying you have water in your DHD, or just under the screen protector?
I fear it's the former?
Usually that means either you used too much soap or hi you have not let it dry. Remember that you need to wait at least 24 hours for the protector to settle in. They often look a bit dodgy to begin with but it should clear up after a day or so...
Must have been too much soap then. I just took 4-5 drops on the display and have let the screen protection foil drop off before apply.
Phone is dry and I have had it to dry on my heater (not too much heat, of course).
There is no water between screen and protector, but under the touch field and it must be somewhere on the LCD panel, since watermarks look like limited to certain areas in a very straight way (like exact horizontal and vertical lines).
Well, I´ll send it in and see what it will cost. It won´t make sense any other way.
I'm worried that water has managed to get in under the screen ... are you able to show this in a photo at all?
I have seen that some of the marks changed and put it into a box filled with rice. It is on the heating for two days now and I'll try to hold myself touching it before the weekend.
I reflashed my Diamond and stick to it until then...
Believe it or not, but drying it in a closed box with rice helped.
There are no more spots visible and it looks like new.

Garbage or nah?

I was watching YouTube a few days ago on my h918 and noticed half of the screen went fully dim, back to normal, then back again. Panicked, i restarted the phone. Upon boot LG logo was half dim so i ruled out a software problem. I then disassembled the phone and noticed powdery corrosion covering the screen to motherboard connection. Cleaning the metal contacts didn't solve anything. Would simply replacing the screen fix the problem or could a chip/module on the motherboard be responsible?
I used to repair hundreds of smartphones with that problem when I used to be a phone tech a long time ago, when I come across a powdery corrosion, it's usually from water, meaning the phone was submerged into water in the past and the water rusted a bit on anything metallic, plus when water dries it leaves substances of flouride/dirt/chlorine/salt etc. Best thing to do before spending any money is get a soft bristle toothbrush and lightly brush any foreign debris away and clean the mobo and LCD connector as best as you can then assemble the phone back together and power on the phone then test it with normal uses through out the days.

The screen is completely black now. Tried tooth brush (thank you), and qtip with alcohol as a last resort, no success. I noticed the area of the glass on the corresponding side of the LCD connection becomes extremely hot immediately when powered on. Hmmph, will probably buy another one instead of risking it on a new screen. Funny im writing this on my old G3 i had to bake in an oven to get to boot up. LG hates me.

In water for ~15 minutes, 1m deep

Hello,
my Redmi Note 7 fell in the water of our harbor and it took ~15min until we were able to find it. The water was ~1 meter deep.
I put the phone in rice for 4 days strait away. At some point the phone started but was discharged the next day. After that the phone did not start or charged anymore but showed a battery symbol.
We took the phone apart and cleaned everything with pure alcohol. We replaced the battery too. I took a few measurements: There is 5V on the battery test point and 4.8 V too.
At some point the phone showed 80% while it was off and attached to a charger today.
At the moment the screen goes on for a very short time ~1-2 sec. when powered on but does not charge when connected to a charger.
What could I do to bring it back to live?
I mean there are working parts in it as it looks like.
It's DOA.
The only way to save it was to pull the battery asap (in salt water even that might not be fast enough), disassemble, flush liberally with warm RO water, flush, flush, then flush with anhydrous isopropyl alcohol to absorb the water, dry for at least 2 days with a fan in a warm room.
Water is the best solvent for brine...
What has happened is water/alcohol insoluble corrosion has formed on contacts and any exposed conductors. BGA chipsets, flat pack ICs, power circuits and PCB traces may be shorted out completely especially V+/ground rails. Once this happens it's beyond salvage... sorry.
You could try a pulling all connectors and dumping the whole lot minus the battery and frame into a mild acid bath for an hour then rinsing throughly with RO water, then isopropyl alcohol, drying etc. Which acid, concentration, and time? Probably very diluted sulphuric acid. It's a mix of copper, silver, tin and more alloys you're trying to clean.
That's the only way to remove the corrosion if present. The acid could easily destroy exposed (no conformal coating) fine pitch PCB traces. As long as any corrosion remains it will continue to corrode.
I don't give it a good chance of working...
Oh man that sounds bad. I thought there would be a chance as it was more sweet water than salt water and the phone worked after the incident for a short time.

Disconnect the battery.
You can try disassembling it again. Pull all ribbon cables and connectors. Place in warm/hot RO water, clean contact surfaces the best you can with a toothbrush or a ultrasonic gum cleaner if you have one. Try to get some water flow under the BGA chipsets.
Replace the RO water at least 2 times and leave in it for a couple hours*.
Inspect contacts, surface mount devices, traces, etc with good light and a optic aid for signs of corrosion damage afterward. If none if seen proceed to the 99% isopropyl alcohol flush and dry completely. It might work....
*water may get in between the display and screen. If so it will leave a residue upon evaporation. This must be purge before reassembly. A vacuum drying chamber can be used. Use your best judgement how the proceed with the washing phase depending on this issue.
If it's sealed, no worries otherwise you may wish to modify the washing phase to be less invasive by limiting time and exposure to the display.
The contacts on the display is what really needs to be cleaned...
Today I found the phone is alive indeed. After lots of cleaning with alcohol it came back to live. Everything work.
The only issue I have is water (or alcohol) in the display now. This causes little clouds of brightness and the many random touch events.
Its there something smart I could do to get rid of this last bit of water except a vacuum chamber. It might vanish if I heat up the phone for several hours near/on the heating with a towel in between (not to hot).

It's never a good idea to clean everything with solvents such as isopropyl. It can weaken many of the adhesives used in electronic devices, and it will ruin your display panel. If you have access to a temperature chamber, you can try removing the battery, putting the device in a bag of rice or desiccant beads, and let it heat soak for about 2 hours at +60c.
Chances are your display and touch panel are ruined, however. NEVER soak a device in alcohol or any other solvent.
Well the alcohol "everywhere" was an accident and bad luck. It happened while I cleaned just the last parts and connections. I will try to remove the battery and put the device with rice somewhere warm with a thermometer to check the temperature.
Thanks for the help. I will report what happens next.
I am able to get the few messages and photos from the day it fell in the water now. So I am near a 100% data (backup from ~2am + current backup) rescued scenario very soon. I am very happy to have reach this point so far anyway.

The accident was dropping it in brine water... without through rinsing it be a goner. Even with rinsing it still may eventually die.
Rice does not work. Heat does*.
Be patient.
Warm dry room with fan on it.
The problem now isn't drying but the residue left behind as the water/alcohol evaporates. Try using centrificule force to move the water although capillary may prevent this.
Try drying on end.
Careful use of a shop vac might work in a dust free room but could destroy the display. Use best judgement. At the worst if you just let it dry it probably will leave some water marks, maybe not.
*raise heat to 110-120°F if it's not drying after 2 days. Heat displaces water ie hot boxes used in tropics.
The phone worked perfectly with clouds of water in the display.
After I put the phone in a warm place to get rid of the last few parts of this moisture the screen was black and stayed this way.
Now the lowest part of the phone gets very hot when switched on. Its hot enough to burn your fingers. The funny thing is that with "scrcpy" I am still able to reach the screen and the OS works perfectly as normal. I guess the lower PCB with the USB-C is the part which gets this warm.
I am angry for myself as I could have lived with the few clouds in the display as a reminder to keep water and smartphones away from each other.
Better than broken ribs...
You would need to carefully separate the display from the glass and clean both. Probably bonded with a heat adhesive.
The hot running suggest the phone isn't completely dry or has damage. Pull the connectors off the port pcb and inspect both them and that board for visible corrosion damage.
Reexamine the mobo's power section for same.
It's all probably academic as it likely will fail completely in time. Rust never sleeps.
