USB error on screen

I have a USB error on my tv that is stuck on the screen and won't go away. I only used the USB once and this happened. I just want to remove the error from the screen otherwise the tv is fine. I really don't even need the USB to work.

ANSWERS:

"Oh maybe I should have put my comment here. I would try a factory reset.

Instructions here.
