Water damage , won’t turn on

Hi,

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the earbud's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away

First do not try to charge or to turn on your earbuds and then remove the battery as soon as possible from the earbuds to minimize any further damage.

Then you need to dis-assemble the rest of the earbud and clean all the affected parts using Isopropyl Alcohol 99%+ (available at 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 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.

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

Here is a video that shows how to replace the battery which may help as it shows how to open the earbuds etc.

You may also have to replace the battery if the water has caused it to fail. Search online for Z55H battery to find suppliers that suit you best. The battery model number can be seen at 8:07 minutes into the video

If this process seems too daunting, take your earbuds to a reputable, professional electronics repair service, experienced in liquid damage repair and ask for a quote for a repair.
