Disconnect cables at all board receptacles.
Remove 8 T-20 screws:
ï‚§ One is a long grounding screw found at the lower right
corner of the board
ï‚§ One screw is difficult to locate next to and above the
transformer receptacle near the right center of the board
ï‚§ In all cases, locate the specific screw first before you
attempt to remove it: a misplaced screwdriver may
damage nearby board components.
