Accident, Did I damage my Raduino

So, I assembled my Bitx40 kit, at this point it was just wires laying on my bench. I wired up the function button, tested, everything working great.
Accidentally touched the ground from function button (orange wire) to 12v while moving stuff around.
Now my LCD only shows squares, and I can not tune the radio.

So, I am a newbie here, What happens when 12v is applied to the function button ground?

Am I screwed?
