Why will my phone not power up? (Stuck on Samsung screen loop)

[AC Question]

After experiencing some water damage to my phone, my device was extremely slow to charge. I ordered a new battery to fix this problem, but now with the new battery inserted I cannot get my phone to turn on. I power it up and it will show the Samsung Galaxy s5 logo, go black for a second, and show the same screen again. The only way for this to stop is to take out the battery.
