Ok i was cleaning my battery contacts and my usb pins with 91% isopropyl alcohol and got some on the white square and it turned kind of pink (small faint pink spots)...like as if water damage was done...any suggestions? am i screwed on warranties?
Buy some new water detecting stickers off ebay and cut to size. If not Satan I mean ATT will black list you for warrantys when they ask you what color it is, they dont care why its pink, its broke and your fault even if it never had water damage, no joy!
Spend the 8 dollars plus .42 cent shipping to ease your issues Just my personal experiences.
Well, it's definitely a lot better than having water on it. Alcohol boils at a lower temperature, meaning it will dry up a lot faster. Keep the battery out for a few days and put the device in rice to drain everything out. Hope it goes back to normal.
do you have a link for those stickers..i cant find them anywhere

I'd bet it is not reacting to the alcohol at all, but to the water in the alcohol. Remember even 100% alcohol isn't (or is only fleetingly). The instant you open the container and expose it to air it starts absorbing water.
I got a G1 and got it wet now it works fine till the screen goes in timeout it dont want to came back it normally happens doring a call i already have the phone on never to time out i downgrade to rc29 then rc30 then rc33 and back to rc30 with no result same old problem after the screen finally cames back I get a notification telling me to close the program it was running before.any help will be appreciated.
Dude, take the battery out and put a fan or something on it to let it dry. The more you use it the more you risk a short. It sounds like your phone might be OK, but let it dry overnight at least.
Good Luck!
I've done that to 2 phones in the past. The deal is the phone may work for a couple of days and die out for no apparent reason. The more you use it the worse it with get. To dry out properly means putting it in a windowsill for 2 weeks to insure complete drying with the battery and sim card removed. But corrosion and rust can still take place and your phone will never be the same. BUT... you can save it with 90% success rate if wanna take it apart. It's risky but with the right tools it can be done by anyone. What you need is a G1 manual from HTC here (here ya go... www.mikechannon.net and a torx screwdriver. Take it apart following the pdf disassembly guide and dry out what you can with a dry rag and then clean it out with isopropyl alcohol and an old toothbrush (just dip the brush in the rubbing alcohol lightly). Just be care with disassembly and all the ribbon wires (they break and tear easily). And if the screen has condensation, I would consider taking it apart also (that part was somewhat difficult and yes I have done it for fun, lol!) Good luck!

taking it apart is an excellent idea. i did that when i dropped my sony erricson K750i in the bath (lol ><), left the pieces on a radiator on low heat for about 3 days and it worked fine.
thank you for the responces but.....
i did let it dry for about 3 weeks i was hoping it could be software related since it gives me those application closure pop ups. otherwise it works fine i might just go back to my trustworthy dash.
Have you done a factory reset? If not try that and see if the problem goes away.
let it dry, once its dry get a replacement
just make sure you say you have no idea how it stopped working, if you say it got wet they will probably charge you for it
Well, if you open up the back, there's a little dot there beneath the battery. That's there so that T-Mobile can tell if you got your phone wet. If they find out that you did, they will bill you for the new one.
The best thing to do would be to try using a teeny tiny bit isopropyl alcohol on the dot to see if it changes back. If not, you should take it apart and swab most of the nonelectric pieces.
i've done this to a few phones but i can usually have them up and running in less than an hour and they work perfectly, what i do is take the phone apart to every component, completely submerge each piece in ethenol, isopropal alcohol works too but i can get ethanol for free, the alcohol is highly volatile and will actually absorb water and evaporate with it, after taking the pieces of the phone out of the alcohol i scub it with a toothbrush for 5 or so minutes making sure that each part of that piece has been scrubbed from every angle, then i place the parts of my phone on a dry microfiber cloth and move to the next piece. when i have dipped and scrubbed all pieces i run them under a hair dryer on high for ten to fifteen minutes and put the phone back together. all my phones still work and one took an hour long bath in a lake, i had to go snorkeling to find it and thought it was a lost cause, the only reason i bothered to fix that one was to win a $100 bet that i could.
Keep the phone together
get a plastic freezer bag and fill it with dry, uncooked rice
place your phone in with the rice and make sure the phone gets submerged under the rice.
Let it sit for 24 hours.
I've seen this fix phones that had dr pepper spilled on them, dropped in toilets, even washed.
And hell its easy.
In the summer I've rescued a phone by putting it on top of an air conditioner vent to dry out. The key is you want to bathe it in VERY DRY air - you want to dry it quickly. You don't want too much heat - but you need it to be very dry.
The isopropanol suggestion is probably good, although I'd be a little concerned that it might damage some of the plastics. You're basically washing off the water with another solvent, and that other solvent will dry off much more quickly. Isopropanol and ethanol are relatively easy on most plastics - I'd avoid anything like acetone as that is more likely to fog your screen/etc. Solvents that aren't miscible with water (ether, toluene, etc) won't work.
Oh, and those solvents need to be fairly concentrated. Many household solvents are more water than anything else - you're not going to get as effective drying if you're using something like 30% ethanol (it is still 70% water).
Above all, take out the battery IMMEDIATELY after getting it wet. Once the battery is gone your only real concern is rust, and that takes a while to build up.
Oh, if you get it wet with salt water you might want to wash it out with clean water first (again, remove battery first). You don't want salt deposits left behind. Do that before rinsing with a solvent - the solvent isn't going to effectively remove salt (depending on the solvent).
With proper care (and assuming no serious shorts already happened) there is no reason you can't dry out a phone. Half of those components were probably washed with water during manufacture anyway. As long as you get rid of contaminants like salt, prevent rust, and make sure there is no residual water when power is applied you will probably be ok.
Regarding putting the phone in to the bag of dry, uncooked rice.....
Did you leave the back on the phone, or did you remove it to get better absorption?
Regarding drying out the phone in a bag of dry, uncooked rice....
Did you take the back cover off the phone to get better absorption, or did you leave it on?
Homer says "Doh!"
Well I washed my G1 in the laundry last night for 10 minutes before I realized where it was. (Thank you Thank you for the <insert stupid group here> nomination...)
I removed it from the laundry, removed the battery, soaked up all the water I could with paper towels, put the vacuum cleaner on it for several hours (moving from hole to hole to try to pull all the water out).
It booted this morning, but there was a fine film in the display and I had the same problem as the thread creator turning the screen on after it timed out.
So at work I put it in a vacuum chamber for several hours today.
Now the screen and rest of the phone looks perfect, all radios, touch, gyro and other hardware widgets work fine and all software seems fine.
But, I still have to hit power several times to get the screen to turn on without it either turning itself back off or it washing out to some random color (red or green or blue or white).
I think it is actually turning on quicker now, so maybe it will completely recover. Fingers crossed. Once on it seems to work fine.
WET PHONE - my two pence worth
WET PHONE - CLEAN WATER is the best hope you got (not going down the toilet route!!) :-
(( NO HEAT, unless really good air flow!! ))
1 - hold vertically upright, give fluid chance to run out ((pref opposite from where it came in!!))- WHILST - removing MAIN battery ASAP
(even the internal one - if you know how,) and can do it quick (can 'O' air!), aswell as, remove the covers <<Disassemble IF YOU CAN>>
((( NO HEAT, unless really good air flow!! ))
2 - centrifugal force ! <swing in one arm, around afew times> forcing fluid out wards (BETWEEN BOARDS!'"
"give fluid chance to run out ((pref opposite from where it came in!!))",
say 2 times with top outermost, then say four times with the bottom outermost -
arm outstreached fully infront of you, and go FAST "like winding a 6 foot wheel" think of ball on record player.
3 - small tin of "silica gel satchets", get them in lots of packaging <keep them or (or DRIED pasta, rice, peas)> mines in
attic next to entrance hatch, Tape box shut to keep agroscopic properties until needed, during, and after using!!!!!!!!!!!!
never personally had to do anything else **most times skipped 2**- maybe rest may help you !!!
a - compressed air (can / keyboard cleaner 'AIR') < never had a compressor / gone to the garage > - blow the EXCESS fluids out -
<<BEWARE screen, speakers, mics, DON'T LIKE THIS>> but under S.M.IC's, "connectors" (ribbon/wire) and (brown/see through) ones only (not the tri coloured foam stuff 4 LCD's!!!
b - internal battery maybe still powering things, while still wet=(short circuiting parts/portions of parts) starting the corrosion
c - if you try to use it before completely dried, will probably cause, either/both of:-
<"corrosion" of (circuit board) or (full/part -component) which is RUST!!> This will extentivly shorten the life of, and WILL eventually kill it
<instant failure of some components> due to short circuit, ( HOW MANY <replaceable> FUSES ARE IN YOUR PHONE ? ) -
(( NO HEAT, unless really good air flow!! )) THEME running through this!!

i dont have rice in my house atm (no idea why), will lentils work?
Hi guys, I recently fell into the sea by accident and my phone was in my pocket and it got wet. I did not know what to do and i thus took out everything and wiped it dry and then plugged it into a power source. No response. After a few tries, it started vibrating madly and the light on top of the device started flickering. The phone started heating up like mad until finally i switched off the power supply. Now it is not giving any response. Please Help!!!
you fried the board.
In future if you ever get a phone/anything electronic wet, immediately remove the power source (battery) and leave it to dry in a well ventilated place for a long time (or a bag of dry rice, which can draw the water out). And when you think it's dry, leave it a bit longer still!
Don't be curious and try turning it on "to see what the damage is", as you will invariably cause more damage.
Unless it's tap water that's spilled on it (or it's been submerged in) you will likely want to wash it out before drying it - pure, deionised water is good for this. This might seem mental, but it's not - pure water is generally harmless to electronics unless there's current running through them. The residue from dried seawater or coffee will cause short circuits and damage the thing, so best to wash it off.

Seawater? Ouch. If anything salt will kill the motherboard faster than the water. But yes, you made a mistake by plugging it into a power outlet after drying it out. Next time (which hopefully does not occur), pull out the battery, dry it out, and stick it in a bag of rice or silica gel packets. Waiting a few days before touching it would also be a good idea. You may be able to try this now and to rid of the salt, soaking the phone in 100% rubbing alcohol (only 100%!) may clean out the internals. Good luck!
By the way, I haven't tried out the alcohol method but it was suggested by other forum members. The worst case scenario with the alcohol is that some of it seeps into your screen and won't evaporate, so try out the rice first.
It's a common misconception that water conducts electricity. In fact, it's salt water that conducts electricity. The problem is our skin has minute amounts of salt on it. It has been tested already making a completely water submerged PC as an advanced cooling method such as using cooking oil. The plus side is for circulating, water isn't as thick & flows faster plus it don't "go bad". The downside is you have to be very careful not to let salt get into the water & how hard it is to find "pure water".
P.S. DO NOT TRY IT YOURSELF. Even Mineral Oil can be dangerous to PC parts if you don't know what you are doing, plus Oil dissolves rubber & plastic parts over time.

Are you joking? Water conducts electricity. Distilled water (saltless) conducts electricity. Mineral Oil != water! And it does not conduct electricity (the pc cooling projects).

You may be right that distilled/Pure water conducts electricity, for that matter everything conducts electricity if enough voltage is applied. Even air as proof by Lightning. Computers run on 12/5 Volts though (except the Power Supply that turns 220/110 Volts into 12/5 Volts). This is not enough voltage (the 12/5 Volts) to pass through Pure Water. The point is people have tried it & it works. Would I recommend it to someone, NO. As I said, any contaminants will increase water's ability to conduct electricity. There's parts in the PC that can give off salt & other contaminants into the water. Our devices work on less than 5 Volts. If you take the battery out immediately & let dry out completely. You can save the device. I've done it myself & helped others save their doing this. The best choice for a advanced cooling system is this 3M liquid, but it's extremely expensive.

Excuse me, Distilled water has no free ions which are found in normal tap water (minerals, K, Na, Mg, F) that's why it won't conduct electricity, but as " drkfngthdragnlrd " said at extreme voltages not currents, it totally can and that's what's exhibited in stun guns for example where air itself connects..
Hello Fellow note 9 users,
Please any advice will be appreciated, i got drenched by rain and my note 9 display starts blinking and some parts of the screen wont even respond. I couldnt power it off because of the pin which can be entered due to the scrren defect. so i kept it in rice for a day and also used hair drying, to my suprise, the affected part works so i have been able to switch it off because the screen still blinks and not stable.
What can i do again because the price of the screen it out of this world. any advise please
Power it down immediately!!!
It must be opened and dried ASAP!
Disconnect the battery first.
Flush with copious amounts of anhydrous isopropyl alcohol. Allow the alcohol to absorb the moisture then displaced as much of the alcohol as possible using a flinging motion or better, low pressure compressed dry air.
The room humidity should low so the hygroscopic isopropyl doesn't grab moisture from the air. It is flammable!!!
Allow to dry completely before plugging battery back in.
A day or two in a warm dry room with a fan on it should do the trick.
Time is of the essence to save this device!!!
thank you, i have opened it and blowed it with low pressure air. although its still opened. i will need to get isopropyl alcohol then.
Thanks for your help. i just hope it works

Disconnect the battery. Energized circuits corrode.
If there's no apparent moisture, leave it air dry in a warm room for a few days with a fan on it.
If any moisture gets into the microconnectors for the ribbon cables it can behave like that.
It can be difficult to detect... one small drop is all it takes.
Alright thanks. will leave it dry
Once my Buds case fell straight into a full cup of coffee, cream and sugar. Fortunately the Buds weren't in it.
After a brief deep cup savage mission I tore it straight apart. The battery is spot welded in so in it it stayed. Fortunately I has RO water to flush out the sugar with and I always keep a bottle of anhydrous isopropyl on hand. Chased the RO water with alcohol and left it to dry.
A day later I checked it out. A-OK, a little bit of sketchy performance at first but that soon subsided.
2 years later it's still is working.
Fast action can save devices even from coffee
If it's salt water though... it's already dead
I have dried the phone well, but can I use methylated spirit to wash the internals, It contains alcohol also. Or what do you think

No! 99% Isopropyl alcohol only. Drug stores have it although it may be 96%, not perfect but acceptable. Don't use 70%
No telling what additives are in denatured ethanol alcohol.
Ethanol it's self may react differently to the plastics than isopropyl.
You want to limit exposure time as well; permeate everything and get it off as quickly as possible.
NEVER use any kind of solvent including isopropyl on or near a LCD display, it will kill it.
Hello, thanks for the help so far, I got isopropyl 88%. Is that fine? Can I use it on the motherboard?

That's 12% water... not good. The purpose of using anhydrous isopropyl is to absorb the moisture thereby displacing it.
That extra 12% is a lot of water you don't need.
You're better off leaving it open with a fan on it in a warm dry room.

No. Anhydrous isopropyl is 99% pure isopropyl alcohol, the rest in water.
You want it's chemical and physical properties.
I have no idea how that combination would perform. You already have one rogue experiment running, don't add more variables to the mix!
At this point just leave it open and allow it to dry completely.

I finally put it up yesterday and it came up. the screen and all works but i noticed the screen is a bit faint, i mean not sharp and when i lock the phone, before the AOD shows, i notice like a white flash towards the bottom of the screen.
please what can i do again,
I noticed something again, if i increased the brightness totally, i wont see that blurry aspect again. everything just looks good but very bright, but once i decrease the brightness to the normal level, i start seeing that blur and thick lines underground

Still has moisture present or contacts got corroded. Pull the battery!
If you can pull off the ribbon connectors the display, carefully do so.
Disassemble as much as possible then flush it well with anhydrous isopropyl. Remove as much of the alcohol as possible, allow to completely again. It will need extended drying time if not fully disassembled. Keep the drying area warm (heat drives out moisture) with a fan on the phone. You can make a warm box for it if you leave in the tropics. Any heated semi sealed enclosure with a couple cubic feet or more of space will do but keep it the temp below 140F.
Observe ESD protocols as best you can as static discharge can easily damage out of circuit subassemblies.
Make sure, at least, the room humidity is 50% or higher when handling. Use a bare wood table or piece of wood to work on if you have no ESD mat. Discharge yourself to an earth ground frequently if no wrist strap but do not touch earth ground when handling components.
If you can feel, see or hear static discharge, it's already way more than enough to cause damage.
Move to a drying area when done, but reassemble using ESD protocols.
thank you for all the help so far, so i should discharge myself continuously, open up the phone again and dry out the board and wash with isopropyl and dry out again, right.
thank you

After doing all you mentioned, heating the board countless times with even hair drying, powering it back on, still gave me the same result. I dont even know what to do. i might do a little video of the screen so you see what i am saying.
The chances of repairing this device are not good. The battery may have been connected too long after exposure. Every time you connect the battery before it's dry, the more damage is done.
Using a hair dryer is not recommended.
It needs to be torn completely down at this point and all ribbon cable connector pins inspected. The mobo may have corrosion damage. If it's under a BGA* it's not practical or easy to repair. Corrosion damage is insidious and progressive once started.
If it's just water with no formed corrosion under a BGA, in a connector socket etc, anhydrous isopropyl alcohol can be used to chase it out.
Pull all ribbon connectors first. You'll need full access to the mobo and display.
Flush well and repeatedly. Use low pressure dry air to blow off as much of the alcohol is possible.
Pay special attention the BGA ICs, blow the alcohol out from underneath if possible.
Out of circuit subassemblies are susceptible to ESD damage ie static discharge. ESD procedures should be used when disassembling and handling the subassemblies. Leave dry in a warm dry area with a fan on the parts for at a few days. All areas including under the BGA's must be completely dry before powering it up again.

My Samsung mobile phone has fallen into the water because of my fault. But soon after I took it from the water I turned it off. Since I have never faced a situation like this before I searched for some instructions using the internet on my laptop. While searching on the internet I found some directions to solve this and save my phone. But after following those steps still, the phone won’t turn on. To fix this phone,
Soon after I took the phone from the water I put it in a rice bag to remove the water inside it (Nearly 24 hours).
De-assembled the phone as I can (It has a non-removable battery)
Put the phone inside a rice bag for 6 hours and tried again.
But the phone won’t turn on. Is there any other way I can fix this phone? Or should I take this to a repair station?
Rice does nothing.
Pull the battery asap. The phone must be completely dried before connecting the battery again. Pull the rear cover, disconnect the battery and place on side in a warm/hot, dry room with strong fan on it. Give it at least 3 days.

You're welcome.
You disconnect the battery via it's ribbon cable.
Even when powered off there are circuits that have power going to them. This current exacerbates the corrosion and destruction of key circuits.
Anhydrous isopropyl alcohol (>96%) can be used as a drying agent. LCDs displays can be poisoned by any solvent, do not use on LCDs.
Flush liberally with isopropyl alcohol then get as much as possible off the assemblies as fast as possible in a dry room. Isopropyl alcohol is very hydroscoppic and will grab moisture out of the air, it also cools as it evaporates, attracting any moisture in the air. It is flammable...
After doing this allow to dry for 2-3 days as described in previous post.
Avoid getting the alcohol between the display and glass as this would leave a residue stain. Use best judgment... only use anhydrous isopropyl alcohol not methanol!

You're welcome.
Bare in mind there are BGA chipsets in this phone as in most. Water can seep under the chipset and will take longer to dry. The connectors can also retain water and take longer to dry. Place on side to help in draining.
Low pressure compressed dry oil free air can be used as well, but carefully. A shop vac blower... carefully. This can also created an Electro Static Discharge hazard though. Don't touch the phone and nozzle or vac at the same time. Dry air raises the risk of ESD damage. Earth ground yourself before touching the phone; a ESD mat and wrist strap are preferred. Be aware of this hazard. Generally in circuit assemblies are relatively well protected. Points on the mobo can lack input protection and it's best not to touch them.
Heat drives out moisture ie hot boxes that are still used in humid climates to provide a dry environment for humidity sensitive equipment. Up to 120F is perfectly safe for drying. Don't expose the display to direct sunlight to speed drying though. Good luck.
