Hi,
I helped a friend with a panel upgrade yesterday.
We replaced the Pana panel with a Samsung 43" Q60A.
It was a perfect fit.
We drilled a series of holes in the speaker cover where the IR receiver is placed (Samsung logo).
We could protect the fret while drilling by pushing in a metal plate through the speaker opening creating a barrier between the drill and the fret.
Only 0.5 is cropped by the aluminium frame.
