A while back a friend gave me his Nokia 3210. Five weeks ago it got soaked with water and stopped working. Just a single horizontal black line on the display flashed up when the phone was powered up. Or the entire screen when it was connected to the power adapter. Removing battery and SIM card and holding a blow dryer into to for a minute fixed this issue. I could not believe that humidity was able to hide for so long in the phone and a decent ‘bake’ from the blow dryer was able to fix it. Should I set a robot an buy everything @ ebay that reads ‘water damage’ and is cheaper than 10 US$ ?
Maybe the miracle can be repeated. Maybe this is the way to get rich? Forget about coding. Value up seemingly broken electronics.
