The iRobot Roomba 770 and 780 models has different interface controls, one touch and the other tactile dome switches. I replaced the motherboard after a short and got a touch input that was not compatible with the plastic interface. Therefore I had to convert the board by moving the components from the old board to the new and reconfigure it.
Remove touch brackets
Move over tactile domes
Move the dome switches over to the new board.
Reconfigure board
Remove the resistor R120 to make the controller accept the tactile switches instead.
