CAUTION
• When removing the power board assembly, remove the power cable and wait for at least
5 minutes before taking it out; this will discharge the residual electrical charge of the
electrolytic capacitor.
If you handle these boards before the capacitor charge is fully discharged, you may suffer
electric shock.
• To avoid electric shock, never touch the back of the power board.When handling the
power board, take the side of the board.
• To avoid a short circuit, do not place the power board assembly directly on conductive
objects.

Before replacing the power board assembly, remove the following parts.
• Rear cover: "4.2.8 Removing Media Guide R2" p.4-17
