As a matter of fact, I take pride in testing every Game Frame thoroughly before shipping. In cases where the display layers need compression I usually insert the nylon screw, to save you the trouble, and test again. Unfortunately it appears the screw was forced through the LED grid in transit, likely due to an impact. I’ve never seen that before, but it would take quite a lot of force to get the screw through that PCB material.
Send me an email (jeremy at this domain) and we’ll find a solution.
