1. When the front panel is removed, the VR board is removed at the
same time. Consequently the LEDs cannot be turned on and the
sound volume cannot be increased or decreased from the remote
control.
2. When servicing the DIGITAL board, be sure to connect the earth
land of the DIGITAL board with the chassis frame so that the
earth potential of the DIGITAL board must not be floated from
the chassis frame.
