To Drive Power Flow

Are the power supply voltages (12V and 5V)

to the Drive normal?

Approximately 10 seconds after the AC is

applied, the WAIT display flashes several

times on FLD and the power is turned OFF

automaticallly.

Are the power supply voltages on the MB

board normal?

To Power Supply (System) Flow

Do the up, down, left and right arrow keys of

the remote control permit operations on the

XMB?
