50-80 drop of water by accidentally on my camera

Hi @smilebudysid

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

Remove the battery from the camera and do not try to turn on your camera again until it has been properly cleaned, internally.

You need to dis-assemble the camera 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 which may leave conductive residues 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 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 boards. The ends of any flex cables and their connectors need to be cleaned as well

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

Here is a teardown video that may help.

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