Why does the LG Logo stay on my Android phone?

[AC Question]

As I was charging my Android the LG LOgo stays on. I can't get it to power down or go into any functions

Welcome to Android Central! Which LG phone? Try pressing and holding Power for 15-20 seconds to force a shutdown. Or, if the phone has a removable battery, pull the battery for 10 seconds, then reinsert it and power back on.
