Service Overview
1-1. Check Item before Starting
Maintenance
Before connecting to the HDW-750/730 series camcorder,
confirm these two points beforehand.
If either one or both of these points is satisfied, the HDVFC30W that is connected to the HD camcorder will have the
B/W video picture on display.
If this error occurs, modification of the HD camcorder is
needed.
Points to be confirmed
1. Version number of the ROM on the AT-143 board of
HD camcorder is “V1.51 or lower”.
n
Version number can be confirmed using the DIAGNOSIS menu of HD camcorder.
2. Serial number falls within the followings:
HDW-750 : 70001 to 70557
HDW-750 : 10001 to 10400, 20001 to 20003
HDW-750P : 40001 to 40097
HDW-750CE : 40001 to 40036

If modification of HD camcorder is needed, contact your
local Sony Sales Office/Service Center.
1-2. Check Item after Completing
Maintenance
When maintenance work is completed, check that the
SEL1/SEL2 selector switch is set to the SEL1 position
(lower position).
If it is set to the SEL2 position (upper position), the
BRIGHT/CONTR/PEAKING adjustment controls are
disabled.

1-4. Circuit Description
PR-267 board
The input Y, Pb and Pr signals are passed through the
buffer and the pre-filter and are A/D-converted to the 10bit digital signals. Then resultant signals are sent to the
FPGA.
The digital input Y, Pb and Pr signals are clamped inside
the FPGA, receive the BRIGHT, CONTRAST and PEAKING controls, and are finally converted to the RGB signals
that are output to LCD. The above controls are realized by
A/D-converting the analog control voltages from the VR280 board and are supplied to FPGA.
The H1 signal and H2 signal are generated from the sync
signal by the two comparators. The H1 signal extracts the
zero-cross point of the three-level sync signal and the H2
signal extracts the sync signal near the zero-cross point.
The H1 and H2 signals are supplied to FPGA that generates the H and V sync signals. The LCD drive pulse signals
are generated from the H and V sync signals. The LCD
drive pulse signals that are thus generated are supplied to
LCD together with the RGB video signal and the LCD
gamma correction voltage.
The various controls from the camera and VF are sent
through IIC and are processed by FPGA from which the
control commands are distributed to the respective circuits
as the control signals as necessitated.
RE-208 board
The RE-208 board contains the following three types of
voltage regulator. 1. The voltage regulator supplying the
analog and digital signal processing, generating the 3.1 V
regulated voltage. 2. The voltage regulators supplying the
LCD drive voltages, generating the 10.5 V, 20 V and -7.2
V regulated voltages. 3. The voltage regulator supplying
the CCFL drive regulated voltage.
The maximum contrast of LCD is set by the variable
resistor located inside the LCD. The LCD contrast can be
controlled within the range with the use of CONTRAST
under the maximum contrast set by the above variable
resistor.
VR-280 board
The VR-280 board contains the two sets of BRIGHT,
CONTRAST and PEAKING controls. One set of these
controls is for the external control. The other set of these
controls is for the internal control. Either the external or
the internal controls can be selected with the use of the
SEL switch. The VR-280 board contains the tally lamp
drive circuit that turns on or off the TALLY lamp in
accordance with the command supplied from the camera.
The VR-280 board contains also the switch that inverts the
scanning direction from the right or left of display screen.
This switch is interlocked with the viewfinder barrel
presence so that the appropriate scanning direction is
automatically selected as the viewfinder barrel is installed.
SW-1092 board
The SW-1092 board contains the tally, zebra, marker,
B&W and MAG function selector switches. The status
information of these selector switches is sent to the PR-267
board.
