I'm trying to locate the overall system controller on a video board, that
handles IR remote, physical keypad functions and power on/off of main power
supply etc. Mulilayer board of course but all I can find is dedicated
digital video processing chippery. This is quite a thick pcb , does anyone
hide SMD controllers recessed within the thickness of a pcb? there is a
mysterious black piece of plastic in one area , well bonded to the pcb but
no outline of anything underlying it
