Hi Josh, It seems like the nut attached to the small bolt holding the antenna has come loose. I’ve tried my best to remove the panel, but to no avail. My Insignia HD has a little different configuration then the one you posted, and has only TWO phillips screws near the top. Any suggestions on how to remove the panel? Thanks, <michaelk29@hotmail.com>
