HTC Desire 320 won't power on!!

[Android Central Question]

I have a HTC Desire 320 that dosn't react at all.. The kids were playing with it watching youtube when it suddenly died and I haven't been able to turn it on since then. When I hold the power button the backlight turns on, but as soon as I let the button go it turns off. It dosn't react to any charger or when I connect it to my PC. The battery has charge so it's not that. I can't even get in to the recovery menu to do anything. Anyone who knows what this could be?

Welcome to Android Central! How do you know the battery has charge? Leave it plugged into a wall outlet for at least 4-6 hours undisturbed, then press and hold Power for 20 seconds. If nothing happens, the battery probably failed.
