Need help making a slight adjustment to my screen

[escapepodgames]

Hi, guys - the last project you helped me with (lighting my quarter slots) was such a success that I have a new one for you!

Observe the two pics I am attaching.  This is an almost new screen but lately the top 1/2" or so is a little out of adjustment.  Maybe I am being too picky but is this an easy fix?

I attached a pic of the control board I assume has the key.  The guy who sold it to me said to be very careful making adjustments on these knobs as you can get yourself in trouble...

So before I put that screwdriver in my hand I refer to you experts!

Thanks!

Just to be clear because you cant really see it in this pic...

Its like the top 1/2" has been skewed just a little to the left. The rest is perfect and I am not too worried about the fact that some stuff is cut off the top as long as its straight because I know there can be a difference from game to game (this cabinet has 2019 games)

Thanks!
