First thing to remember is water does not conduct electricity, it is what is in the water.
Someone said use salt, bad idea, that would make the water conductive.

I would remove the cover and inspect for any water spots.
If you can't do that then place it in a warm area for a few days.
Chances are its fine.
There really isn't anything inside a dvd player that would be harmed by a high resistance short if there was one.
Most everything is 3v or 5v and at those low voltages it takes quite a bit of current through a high resistance connection like condensation to do permanent damage.

more likely to corrode something like a ribbon cable made of mylar.

When I was moving a professional moving company did the move (my work paid for it). Upon packaging my tv and then un-packing at location (they built a crate for it), the guy stated I shouldn't use it for 72 hrs in case of condensation and the TV acclimating to room temperature. It was winter at the time.

I used it later that night, but hey, to each their own :)

Awesome, you seem to know the score with this. What if for example it wasent a DVD player but it was something like an xbox360? I gather they are higher power than a DVD player is.

A 360 has higher current inside but the voltages are still the same. The 360 also has the power supply external to the unit which is where the most dangerous shorts can happen.
The thing is that you can get shorts that don't really damage the device but if they say shorted across two logic points and changed it to a permanent 1 or 0 till the short is removed you could think the device was destroyed since it might no longer work.

I saw lots of this when I worked in consumer electronics for GE.
I was in charge of finding out why stuff was returned for repair to see if it was a design flaw or something consumers did.

Edit:
All you windex users out there, stop spraying your screens with the stuff.
It runs down the screen and drips behind the bezel at the bottom, then it corrodes the board beneath. We dubbed it the windex syndrome.

This is dew syndrome and we have big problems particularly in the Caribbean where a camera, VTR, etc. is moved from an air conditioned space around 70F to outside where it can be 85F with near 100% humidity. Condensation forms instantly on the lenses.

On a DVD/CD etc. player it can prevent the pickup from reading the table of contents OR if the disc plays it will skip, stutter and stop. Chance of damage is really minimal although with helical recorders the tape can damage the heads if too much moisture builds up.

Washed phones are usually toast because the battery was in the device. Time for a new phone.

Ooh, that's even better than my reply.

I was thinking more along the lines of put it in a plastic bag & seal it, keeping as much air from the room out of the bag as possible (suck as much air out as you can) - some rice in the bag would certainly be helpful.


Oh, and given that the blackberry starts to boot; I'm going to give it a 30% chance of survival.

I say let it dry for a week unless you really want to use it... Then let it dry for a WHOLE DAY. Not overnight.

Blow Dry it?

I think WD40 would be too corrosive. Might eat through plastic and electronic parts.

That is only if none of the components permanently shorted out. If current ran the wrong away it could have killed something. If you're lucky, you just need to get it completely dried out and replace the battery.

ive had 4 or 5 cell phones drop in chlorinated pool and/or toilet and every time i open it up (as much as i can..which means basically just removing battery cover), blow compress air through it, sun-dry for a few days, and they have ALL returned to 100% operating condition

There's a huge difference between going through the laundry and a dunking though.

Why is everyone suggesting dessicants and drying? It's coming out of the freezer not the spa! :laugh:

It's fucked. Simply.

It depends what happened.

There are two scenarios:

1) Something got shorted by the water and it got damaged.

2) Water deposits or soap deposits are still shorting something causing it to not work, but nothing has gotten damaged. In this case, flushing it out with distilled water and letting it dry will fix it. Probably worth the cost of the water to try it.

Because it's cold, and if it's below the dew point in the room, water will condense on it.

Anyway, any update? Is it working?

The amount of water is negligible and does NOT merit the use of dessicants or accelerated drying bins. As mentioned previously I have plenty of experience with this.

Needless to say, it doesn't work anymore. So I took the liberty of buying some distilled water, and giving it another bath.

Zero if it had a battery in it at the time. Something in it would have took a short circuit, and that part or parts will be DOA. 100% workable after submersion if it was battery free, as long as the screen was not soaked and leaked water into the LCD somehow.

And to the OP, don't worry, a frozen vibrator will work just fine, and what a great idea! :evil:

i've had cell phones go through an entire wash cycle and worked fine after overnight of drying. As long as the LCD screen isn't messed up and everything dries for at least 2 days open, it should be fine. Just don't do anything stupid like trying to start it up while still wet.
