How to get unresponsive power and home button to work again?

HELP ME PLZ! I was playing in snow and water got on my phone so I dried off the phone and battery. A few hours later and the phone power/home button would not work/respond but the volume button does. I tried the rice trick for 24 hours but the buttons do not work still. I don't know what to do and have searched the web for answers but have found none. I don't want to spend lots of money because I am BROKE but will if I have to . If there is any way to fix this problem pls help.

thx.

Hi @clumzyclutz ,

As you now know water and electronics and electricity are not a good mix.

The water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components.

Rice is good to eat but does nothing to fix the problems caused by corrosion

First do not turn on your phone and then you need to with the phone turned off, remove the battery as soon as possible from the phone to minimize further damage.''

Then you need to dis-assemble the rest of the phone and clean all the affected parts using IPA 90%+ (Isopropyl Alcohol, available at most pharmacies) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as it is usually <70% IPA , can contain scents and is not as effective. If you do check the label to verify the amount

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link to the ifixit guide(s) for repairing your phone which may be of some help to you.

If this process seems too daunting, take your phone to a reputable, professional phone repair service experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
