Will not turn on - battery or charging circuit?

Will not turn on - battery or charging circuit? Kindle Fire HDX 8.9" - battery indicator showed power was low, waited too long to plug in the charger, now it will not power up. Tried different chargers, overnight charging, and cables, even a PC overnight. Tried holding power button to reset as well as power and volume up. USB / charging port seems snug.

I just replaced my battery for my hdx 8.9 3rd gen and still won't turn on.

Hi, my fire 8 wouldn’t charge and the screen seemed ‘stuck’ swiping didn’t work. I couldn’t even turn the dang thing off! I went online to the Amazon site and was going to contact them and they said to first try turning it off then back on. Here comes the ‘kicker’, they said to hold the power button down for 40 seconds, the screen would go black and then wait a second to turn it back on. IT WORKED!!! OMG! I guess I waited too long to do software updates. I normally just close the cover instead of powering it off. Maybe it will work for you?
