Hi John, If you are still taking swaps I'd swap my hana v200 for a reference mod. I believe I am experiencing screen issues as well. It goes dark anytime I press the fire button. I don't really have the technical know how to fix the issue so a swap would be amazing! I also sent you a pm about this same issue before I found this thread. You guys are awesome and these swaps are just another example of Evolv's excellent products and service. Thanks, Joe
