locations on the POWER board.
5. After all cables have been disconnected, remove the seven screws holding the POWER board to the cabinet and
remove the board. Take care to hold the POWER board in place until all screws have been removed.
NOTE: If you need to replace the LOW VOLTAGE POWER SUPPLY board, please skip the next step.
6. Replace the POWER board, attaching it with the seven screws previously removed. Don't forget to use the lower left
screw for a ground connection.
