stylisticnewbie:
if you are talking about the four screws that hold the stand on, they are anti-tamper torx screws.
they are like the screws used on cable boxes and such and have a post in the center to keep a standard torx driver out.
i used a hard fine tip jeweler screwdriver wedged between the center post and two corners.
if you want to get the correct screwdriver bit, they are size T-8, anti-tamper
have fun,
