Técnicas para la solución de problemas en dispositivos electrónicos por agua y como arreglarlos.

En cualquier situación que implique la sumersión o salpicadura de cualquier liquido en un aparato electrónico, el "primer paso es desconectar cualquier fuente de energía" tan pronto como sea seguro.

  • ¡Su seguridad es lo primero! Tenga mucho cuidado al desconectar cualquier dispositivo de la corriente o cualquier otra fuente de energía (como, por ejemplo, una batería). Si esta sobre agua o su ropa esta mojada, por favor debe usted evitar cualquier peligro de descarga eléctrica antes de pensar en reparar un dispositivo electrónico sumergido o empapado.
  • Si el dispositivo electrónico todavía está sumergido y está conectado a una fuente de alimentación externa, debe encontrar una manera segura para desconectarlo. Si es posible, encuentre un disyuntor o interruptor para esa fuente de energía. Tenga cuidado si usted decide quitar un enchufe o adaptador de corriente de una toma de corriente que no se ha apagado.
  • La reparación de un dispositivo electrónico sumergido o mojado que contenga una batería presenta sus propios peligros. Una batería en corto puede provocar un incendio y / o riesgo químico. Si usted ve o siente calor, humo, vapor, burbujeo, abultamiento, o fundido de material, debe evitar manipular el dispositivo electrónico.
  • Si el dispositivo aún esta encendido, apaguelo.
  • Gire y agite el dispositivo para intentar sacar cualquier liquido.
  • Si es posible, quite la bateria.
  • Si es posible, desmonte el dispositivo para permitir que cualquier líquido restante se drene y para empezar a limpiar los componentes internos. Esto es particularmente importante en el caso de líquidos ácidos, como zumo de frutas, o líquidos alcalinos, tales como agua de lavado.
  • Si no está seguro acerca de desmontar su dispositivo puede intentar secarlo enterrándolo en un recipiente de arroz crudo durante varios días. En algunos casos, el arroz se secara el líquido restante. Cambie la orientación del dispositivo de vez en cuando en su baño de arroz para dar al líquido toda oportunidad de drenarlo. Evite el uso de sal, azúcar o harina. El desmontaje y limpieza del dispositivo es siempre la mejor manera de prevenir la corrosión, pero si el dispositivo no quedo sumergido, este secado puede en algunos casos ser suficiente para evitar daños mayores. Nota: Algunas pruebas sugieren que el secado al aire libre puede ser más eficaz que el método de arroz, especialmente en áreas con baja humedad relativa.(Source)

Limpieza de Placas de Circuitos ¶ 

  • Desmonte completamente el dispositivo quitando todos los cables y abriendo todos los conectores. Para desplazar el líquido sobrante alrededor o debajo de cualquier componente de la placa lógica sumergirlo completamente en un recipiente de tamaño adecuado lleno de alcohol isopropílico. Lo ideal es utilizar una concentración del 90% o superior disponible en farmacia. Puede utilizar agua destilada o desionizada como fluido de limpieza alternativo, aunque esto tomará más tiempo en secarse. Evitar disolventes tales como cetona, acetona, o nafta (éter de petróleo).
  • Use un cepillo de dientes, cepillo pequeño de pintura u otro cepillo suave para limpiar la placa lógica de cualquier residuo o depósitos del líquido. Tenga cuidado cuando limpie de no dañar o golpear accidentalmente los componentes de la placa lógica. Preste especial atención a los conectores y los extremos de los cables de cinta para evitar la corrosión de sus superficies de contacto
  • Una vez que esté satisfecho con la limpieza de la placa y este libre de corrosión puede utilizar un secador de pelo en su modo frío para secar la placa. Alternativamente, puede colocarla bajo una lámpara de escritorio para calentar suavemente y secar el líquido de limpieza.
  • Cuando los componentes estén secos comprobar los extremos de los cables y conectores de nuevo en busca de signos de corrosión o residuos.
  • Vuelva a montar el dispositivo con una batería nueva o una que tenga la certeza que está en buen estado de funcionamiento. Si el dispositivo se ha sumergido, es probable que usted necesite una batería nueva. Litio y otros tipos de baterías recargables no toleran bien la inmersión. Una vez más, cualquier signo de burbujeo, abultamiento, fundido o decoloración en la batería indica que esta quemada. Deshágase de ella sólo en un centro de reciclaje de baterías.
  • Una vez que tenemos el dispositivo montado, el verdadero trabajo de evaluar el daño comienza. Busque lo que está funcionando y sustituya las piezas de una manera organizada, no todas a la vez. El orden probable de fallo en un dispositivo electrónico pequeño es típicamente:
    • Batería
    • LCD
    • Placa base

pH de líquidos ¶ 

Un número menor que 7 indica una solución ácida, mientras que un número superior a 7 indica una solución alcalina. Ambos casos son malos para los componentes electrónicos. Conociendo el pH del fluido puede ayudar a darle una idea de la gravedad del daño.

  • PH neutro, agua pura = 7.0
  • Sangre = 7,4
  • Jugo Gástrico = 0.7
  • Orina = 6,0
  • Jugo Pancreático = 8,1
  • Líquido cefalorraquídeo = 7,3
  • Saliva = 7,0
  • Cerveza de trigo = 3.3 a 3.7
  • Cerveza Lager = 4.4 a 4.7
  • Cerveza no fermentada = 5.5
  • Jugo de limón = 2.3
  • Lejia = 12-12,6
  • El agua de mar es decir Agua salada = aproximadamente 8,2
  • Agua de piscina regulada= 7.2 a 7.8 (Source)

*sorry Beer dripped inside computer monitor

Alba Ramirez - Contestar

Special Note.

Pure water neutral pH = 7.0 You don't have too much of an issue here -- easy to clean

Blood = 7.4 This may be more of an issue. If it is a large amount and your blood please seek medical advice

Gastric Juice = 0.7 See Blood

Urine = 6.0 If it's yours you may have behavioral issues. If it isn't, do you really want to clean it??

Pancreatic Juice = 8.1 See Blood

Cerebrospinal Fluid = 7.3 Really see blood

Saliva = 7.0 Ex Sneeze, just wipe it off. If sufficient to cause electrical; issue then you have other problems

Wheat Beer = 3.3 - 3.7 Why are there 3 kinds of beer listed

Lager Beer = 4.4 - 4.7 Really Why

Unfermented Beer = 5.5 What about a nice red wine

Lemon juice = 2.3 No comment

Bleach = 12 to 12.6 At least it is not a bio hazard anymore (see Blood, Urine etc)

Sea water i.e. Saltwater = about 8.2 ;)

Thank you, thank you, thank you and thank you!!!!!!!! I love "ifixit".

I had a macbook with water damage. So I open the macbook and diassemble all parts. Then I follow these instruction and clean the logic board with toothbrush and isopropanol. I even clean bottomside of the cpu and gpu with isopropanol and pressed-air. Before that I diassemble the head sink and after that I appy new thermal paste.

So I put all together and it WORKS!!!

fischel - Contestar

Hi fischel, did you dissamble de heat sink before submerging the logic board ?

So pancreatic juice is a "common" fluid?? Not in my world; unless I am missing something.

I have a MacBook Air that is still under warranty and it won't expire for 10 months and I think it has saliva in it. Should I take to the Apple Store?

Dylan Byrne - Contestar

What do you say?Spit in a computer is quality problem?Apple will cost you much.

Zhang Boyang -

Why isn't coffee on the list? It has to be more common than a spill of pancreatic juice.

gwoodward78 - Contestar

No kidding. What about wine?

Thanks for the guide! I have successfully brought several computers back to life using these instructions. I know that putting pouring distilled water on your electronics can seem counterintuitive but it helps rinse off all the gunk residue. Just make sure you dry it well (I put my motherboards in my garage in the summer for 24 hours). I've cleaned milk, water and beer spills so far.

graham - Contestar

Totally water submerged?

Once the unit is away from its power source, way away, take it outside in a ventillated area and pour isopropyl alcohol through the device, letting it displace the water as much as humanly possible. If its a camera try not to overdo it as to screw up the optics, If the optics are already contaminated, the alcohol thing might help but you still need to get the optics serviced.

for non-optical, keep the alcohol rinse/flush going a couple times and let the device either sit out and dry, blow a fan through it, or do the rice trick. The objective is to remove the bad ionization and water from the device. Alcohol dries quickly and mixes with the water. It should leave it very dry inside. If its salty salty salt water, your gonna get limited use of the device after this procedure and it would be advised to get all data out of the device asap (say if its a phone). The ocean salt water will have already done damage and is nearly impossible if not totally impossible to recover from fully

I I fix it! I poured tea over a mac book air and I thought I lost it forever.

So I opened the back and removed the battery and let it dry for a day. Than the next day I followed the instructions on your website and removed the logic board and cleaned it all with IPA and a toothbrush and cotton bud. When it was drying I had some silica gel bag that I kept on it to get all the moisture in the machine... Now it works fine. SO thanks!!

Keep all the silica gel bags you find in boxes and other places as one day they might come in handy!!!

Must the heat sinks be removed before soaking the board?

Ashley Jung - Contestar

I have a Sony Xperia U which worked fine before I stepped into ocean with it in my pocket. It got switched off on its own at that moment. When I at last opened it by myself after 2-3 days of its exposure to sea water, I regretted not cleaning (using isopropanol as I know now) and drying the logic board within hours of its exposure when I observed that some smd components and EMI shields caught rust by that time because of which one very small smd resistor, in the attempt to clean the rust surrounding it that it caught, got chipped off. After that, I used hair blower in hot mode to dry off the board for long hours. After this much,the mobile stopped charging,for a while,using supplied charger(so I bought a cheap 'battery' charger to indirectly charge the battery).Interestingly,the mobile used to switch on(even with the res chipped off!)but yes,it used to take touch input intermittently even when I didn't provided any. power button acted as if pressed even when I didn't press it. Now its not switching on at all

Rishi Khanna - Contestar

Continued...

Now, even with the res chipped off, the mobile, with battery connected, shows the SONY logo and then the blank screen after that (earlier, it used to show a charging battery) when I try to charge it using the supplied charger. So, now, I'm not able to switch on the phone at all using the power button but 'some' part of its electronics circuit appears to be intact as it shows SONY logo while charging it. It may be because that part of logic board is 'misbehaving' which takes input from power button or that the power button (mechanically) itself is not working as I don't hear the low tic-tic sound that usually comes when power or volume up-down or camera buttons are depressed, partially to fully.

Well, one thing that I learned from this episode is that one should not postpone the process of cleaning and then drying the electronics just after its exposure to any liquid.

P.S.: If anyone has any idea of what in the !&&* is happening with my phone, please reply.

Rishi Khanna - Contestar

often these buttons don't need complete physical 0 ohm resistence like a switch. Instead they control a GPIO line with pullup/down resistors so they sometimes can be "pressed" by just touching the wire by a finger for example. In your case there appears to still be something making resistance low enough to press the button(s) - watter or other conductive material.

My phone was in my pocket with a baby bottle, the bottle leaked in my pocket all over phone, it was working fine but now says no sim card and won't work, it onli works on wifi, I took it too thw shop where they took the sim out and told me it was wet inside and gave me a replacement sim, I've had it in a bag of rice for the past hour is there anything I can do as it's a brand new phone with no insurance plz help thanks

Laura - Contestar

I just completed a complete tear down of a brand new MacBook Pro with water damage. I had VERY low expectations. I cleaned the logic board with alcohol and a clean brush - going over the obvious tarnishes a couple times until they were clean. I pulled the logic board and ram out and cleaned both sides. Put it all back together and Holy hole in a donut if fired back up. Un. Real. Thank you you beautiful ifixit people.

I'm not completely confident that I can successfully disassemble my iphone, can I just submerge the whole thing in the alcohol or will that mess up the battery and/or something else?

Sarah - Contestar

Hi,

I followed your direction to the tee. It powers on and stays on until I turn it off. When I shut down my laptop, it does not power back on. Any help is greatly appreciated.

What about milk on a dj mixer

Stephanie Silva - Contestar

great guide, only thing that I see could be an issue is under step 8. you guys mocked people using rice to dry out there phone in your video and know that it leaves starch in the devices. why would you not list silica gel? draws out the water in greater quantities and doesn't leave a residue inside the device.

I just opened my PS3 for multiple issues. When I got to the motherboard, I noticed what looks like Pepsi that dries long ago, to the point it is hard and not sticky at all. There is definitely some corrosion. In multiple places and crossing circuits.

I am going to clean it with alcohol. The spots where it corroded into circuit paths, worried me. Any suggestions to repair said paths?

Rs - Contestar

Thanks ifixit, i would say that i spilled beer in my mac 12, after I passed your method it's working. You help me to save 850 Euro, the &&^&^$^ med store told me that you have to pay.

I recommend to others, don't be afraid you can repair these kind of problem.

Thanks a million with accurate steps

I bought an inverter for my boat. The unopened box got splashed with sea water. NOT SUBMERGED. I removed the inverter (which was dry) and let it sit for a couple of days just in case. Upon installing, it works fine for 100w USB side but cuts out using 1000w side. No visible corrosion anywhere but I have not opened it up. Should I try a distilled water bath then alcohol bath to pull any salts? Suggestions before I crack it open? - thanks

I got rain in my drill, its wasnt plugged in, it was just sitting in the backyard , how to be sure its its ok, i just used a fan to dry it, but not sure for how long

My MacBook pro started acting strange last night after first spilling a small splash of miso soup and then trying to clean the keyboard with hand sanitizer.

When I woke up this morning the computer would not come on, I checked and it is fully charged.

The cursor was moving about on its own and when I tried to scroll down a page the computer would cause the page to quickly scroll up. Needless to say, my productivity was way down.

Question:. Does this sound like liquid damage or something else?

Chelley Hopson - Contestar

Chelley: You probably need a new keyboard. Power button runs through the keyboard so if the liquid has shorted the keyboard the button won’t work.

i dropped my tablet into water, and it won’t stop rebooting. I put it in rice and it’s drying at the moment. Is it still going to be okay if it won’t stop rebooting? it is doing the exact same thing as another tablet i broke a few years ago by dropping it into water

Cassie - Contestar

i dropped my tablet into water and it will not stop rebooting, i have put it into rice and drying bags and it is drying at the moment. What do i do if i can’t turn it off? will it still be okay? is it still possible to save it?

Cassie - Contestar

You saved me $1000 bucks! I spilled brandy in my Macbook Air. I followed the logic board removal instructions on another page on this site and then your instructions for cleanup. I did not know that you could soak whole circuit boards in alcohol, brush off the crud, let them dry, and reinstall them with great results. My laptop works perfectly now. Thanks so much!

Crazy ex- boyfriend poured bleach into my Yamaha Motif 6 music production workstation keyboard. After discovering bleach dripping from the vents, I never turned it on and it stood untouched for over 3 years.  I replaced that machine, but I'm wondering. Did this caustic liquid evaporate or is it perhaps rusted inside? I'm not knowledgeable about this sort of thing, and Id like to ask, what will happen if I turn it on,  now? Is it best to take it apart first before I attempt to power up, or even let an authorized technician take a look and swallow the expense? Any suggestions based on this information would be great. There is not a lot of info out there about bleach inside the interior of electronics. I'm thinking about trading the keyboard for another piece of equipment
