Amazon Fire 8 HD (8th gen) tablet won't charge or completely power on

When trying to power on and also anytime it's connected to a charger it keeps repeating probably about the first 4 seconds of the start up process of sounding off the power on chim while lights up with the Amazon icon which stays lit for about a second then suddenly completely shuts down. I tried powering up while connected to charger and same thing happens, it also continues this routine>>sounding chim-lighting up-suddenly shutting off, the entire time it is connected. After unplugging it flashes empty red battery icon 2-3 times.

**Just an thought but I think that possibly the USB charger end got wet and then was plugged into tablet-- may not have happened or be what's causing problem.
