Chosen Solution

The screen will blink once then turns off, the battery looks like it has a little corrosion on the conectors the red indicator light blinks when connected to charger but when I push the start button it goes to blue for a split second then turns off. Should I replace the battery?

Just treat it like any other device that got submersed Follow this guide and reevaluate after. Good Luck

Maybe you could try putting the battery in alcohol for afew minutes then get a cloth and let it dry then it, ll work just like new
