Remove the two phillips head screws holding the main electronic board in place. The arrows indicate location of the two screws (but they are at the back of the board)

Once the board is removed, disconnect all the electronic cords connecting the board to the rice cooker. As mentioned before, ensure you take a photo of the location of the connectors before removing!

With the board removed, the LCD panel is exposed. Take care of this and the cavity (as any dirt falling in will cover the LCD panel when re-installed)
