Why is only the words Jelly Bean Android 4.1 showing up on my screen

[Android Central Question]

I've had it powered up for 15 minutes and nothing is happening

Welcome to Android Central! Which device do you have? Do you mean that after powering it off for 15 minutes, and then powering back on, it still gets stuck on that screen? It's usually a sign that either the firmware is corrupt, or something on the motherboard has failed.
