3-1 Description of Structure
(1) Differences in structure
The shapes and assembly methods of L case, R case, front case, lens cover, etc. are different among
DZ-GX3300E/GX3200E/GX3100E/BX37E/BX35E/MV4000E for the following reasons:
1) The size and shape of lens unit are different because the size of CCD image sensor is different.
2) Whether the fl ash and accessory shoe are provided or not.
(2) Major circuit boards and units
T
he DZ-GX3300E/GX3200E/GX3100E/BX37E/BX35E/MV4000E include the following boards and units:
(a) Disc drive unit (DRG circuit board):
The DRG circuit board in unit incorporates the disc drive circuit and the power supply circuit
of the entire DVD video camera/recorder.
(b)
Lens unit
(c) EVF unit
(d) LCD unit (LCD circuit board):
The LCD circuit board in unit incorporates the LCD monitor drive and backlight drive
circuits.
(e) AVJ-H/M/L circuit board:
Incorporates the AV input/output, PC connection and external microphone terminals.
H is for DZ-GX3300E/GX3200E; M for DZ-GX3100E; and L for
DZ-BX37E/BX35E/MV4000E
.
( f ) FRT-H/M/L circuit board:
Incorporates the white balance (WB) sensor, remote infrared receiver (IR) sensor, etc. The
FRT-H circuit board in DZ-GX3300E also has a fl ash circuit.
H is for DZ-GX3300E/GX3200E; M for DZ-GX3100E; and L for
DZ-BX37E/BX35E/MV4000E.
(g) GSL-3M/2M/1M/L circuit board:
This circuit board connects the CCD image sensor to MAN circuit board. It incorporates an
EIS sensor, CCD drive IC, etc.
3M is for DZ-GX3300E; 2M for DZ-GX3200E; 1M for DZ-GX3100E; and L for DZ-BX37E/
BX35E/MV4000E.
(h) LMF-H/M/L circuit board:
This circuit board connects the circuit board (incorporating a card slot) in L case to MAN
circuit
board.
H is for DZ-GX3300E/GX3200E; M for DZ-GX3100E; and L for DZ-BX37E/BX35E/MV4000E.
( i ) MAN circuit board:
Incorporates the circuits that control the entire DVD video camera/recorder and the video/
audio signal processing circuits.
( j ) SHE-H circuit board:
This circuit board connects the accessory shoe control/power supply terminal to MAN circuit
board.
It is not mounted in DZ-GX3100E, which does not have a control/power supply terminal, or
DZ-BX37E/BX35E/MV4000E, which does not have an accessory shoe.
