Hi, I have no idea if this post works here, but, I have a Samsung Galaxy S5 that doesn't light up. The battery is fully charged. The LED light at the top of the screen works, the lights at the bottom work, but the screen doesn't light up. It was dropped in a pool. Any help is greatly appreciated! EDIT: Everything works except for the screen.

Mike is right. The problem with electrically conductive liquids inside of electronic equipment is they allow electrical currents to travel across unintended paths. This can immediately damage/kill the electronic components those improper currents traveled through. (Even if the phone was off, the battery is still inside the phone).

In order to find out exactly what might have been damaged and where would not only require all of the proper testing equipment, the knowledge required to use it all as well as to perform these tests on each and every single isolated electronic part of the phone. You now need to find replacement parts for all of those components and then proceed with reassembling, by hand, the entire cellphone. Of course the cost of all of this would far and away exceed the cost of a whole pallet of new cellphones.

The speed of electricity in everyday electrical and electronic devices travels at 50-99% of the speed of light. The speed of light is 186,000 miles per second. Take the lowest end of that percentage would be 50% of 186,000 equals 93,000 miles per second ... and that is the slowest speed. Divide that by 24,901 miles (which is the circumference of planet earth), meaning that electricity can travel all the way around planet earth almost four times . . . in a single second!

How fast are you again? ;)
