Quoted from RobKnapp:
Looks great. However I had one hell of a time centering the light board behind The Insignia . I posted video on DIY thread. You should make a video. Mine came out well but that does not mean there is room for improvement . Like to see more. My be inclined to order. It looks professional .
Oh yeah, depending on how the light was aligned in the beginning, you may have to do what you did by re-aligning with a screwdriver and a small wrench.
My initial rule of thumb is to align it to the middle of the star looking shape and maybe a hair down, then put the white diffuser piece on. Before removing the double side tape on the box, you can get an idea of how it looks before attachment.
My wife is really dying to do video instructions, I just don't know if I can behave myself. Maybe she can do the install and I do the videoing.
