My lg aristo fell in water

Hi @gatorfan73 ,

The impurities in 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. The corrosion process starts immediately and continues until it has been cleaned properly

First do not turn on your phone and then you need to 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 Isopropyl Alcohol 99%+ (available from electronics parts stores), to remove all traces of corrosion and water. If possible, do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better.

Here is a link that in general, describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. remove any shields that may be covering some components as the water and corrosion may be under them

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

Here is a link to the ifixit LG Aristo MS210 Screen Replacement guide which may be of some help.

If this process seems too daunting, take your phone to a reputable, professional mobile 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.
