The back light (fluorescent tube) is driven by a high voltage AC
power supply. Therefore, do not touch the back light holder to
avoid electrical shock.

When replacing the LCD unit, be careful to prevent damages
caused by static electricity.

Set the LCD BRIGHT (Menu display) to the center.
Set the LCD COLOR (Menu display) to the center.

Connect the adjustment remote commander to CN713 of VC-272
board via I/F unit for LANC control (J-6082-521-A) and CPC jig
connector (J-6082-539-A). To operate the adjustment remote
commander, connect the AC power adapter (8.4Vdc) to the DC
IN jack of I/F unit for LANC control, or connect the L series Info-
LITHIUM battery to the battery terminal of I/F unit for LANC
control.

Most of the measuring points for adjusting the LCD system are
concentrated in CN5502 of the PD-156 board. Connect the
measuring instruments via the multi CPC jig (J-6082-311-A). The
following table shows the Pin No. and signal name of CN5502.

Table 5-1-8.

By measuring the resistor value between Pin 6 of CN5502 and
GND, the type of LCD can be discriminated.
