Hi ....i have a nokia n81 8gb cellphone and one of my nieces dropped it in water...i did dismantle it and dry it but at first the screen went blank but after a few hours it was fine. im not sure if the phone is damaged but can you please help me
-   i bought this phone about 2 months and nothing was wrong with it untill today accdentaly i spilt some water on the secreen of the phone. now every thing works exept the joystick what can i do here. i live in sri lanka its very hard to find any shops here that reapares these phones.
Nokia phones of this complexity use at least 3 layer circuit board in order to fit all of those chips and other components in a small casing. When they get in contact with water they can retain it for a long period of time underneath the pins and those black chips. Also, the type of water involved may change way in wich the problem must be treated. Salt water is by far the most dangerous (because aftel the water evaporates the salt cristals remain and may still conduct electricity and form short circuits over the board) followed by water contaminated with foreign particles or other liquids. Normal water will not cause these problems but it can short circuit various components causing damage to the board.
In your situation, i would recomand that you dissasemble the phone, remove the display from the board and wash the board with propionic alcohol (or izopropilic alcohol). This helps by cleaning various foreigh materials or substances contained within the water that had contact with your phone. Let the phone to dry for about 1 day before you try to reasemble it. Don't force it to dry faster, let it in a sunny place to dry on it's own. In any case, never wash the display with this alcohol or anything else as this could affect it's quality or even destroy it. You may get propionic alcohool from electronic stores, radio shacks or service centers willing to sell it.
In case you dropped it in salt water you will need a lot of alcohol because you must place the motherboard in it for about 3-4 hours.
You may also try to simply power on the phone after 2 days (after the incident) to see if it works. Of course connect the battery back to it only after these 2 days.
You've asked if the phone is damaged now? That depends mostly on 2 factors.
How long did the phone stayed in the water and how long did it remain with it's battery connected? The shorter, the better.
What type of water was involved? salt water or sugar flavored or other things are bad.
hi! after receive mi message! first switch off the phone! remove the battery from the mobile! and go to the service centre! then service the mobile! Do it
