1-3. Circuit Overview
PR-292 board
The PR-292 board consists of the video amplifier circuit,
A/D conversion circuit, video processing circuit, clock
generation circuit, tally control circuit, and micro computer.
The analog HD Y/Pb/Pr signal input from CN1 passes
through the pre-filter (FL200-202) and the video amplifier
before it is converted into a 74 Msps rate, 10 bit digital
signal with the A/D converter (IC214-216). It then passes
through FPGA (IC300) before finally being input to the
video processing IC (IC400).
In FPGA, PLL is added to the sync signal generated in the
sync separation circuit and HD/VD is output.
In addition, the parameter settings for video processing IC
and clock generation IC (IC306) are configured, the
internal test signal is generated, and IIC communication is
performed with the connected camera.
The video processing IC converts the input HD Y/Pb/Pr
digital signal into a WVGA RGB digital signal and outputs
that signal. Brightness and contrast settings are also
performed.
The RGB digital signal is entered into FPGA again where
peaking processing and knee correction processing are
performed before the signal is converted into an 8 bit
digital signal. The video signal is superimposed on the
OSD signal and indicator display, and then the signal is
output to the LVDS transmitter circuit (IC700).
The LVDS transmitter converts 8 bit RGB digital signals
and sync signals into LVDS signals and outputs them to
CN5.
RE-237 board
The voltage comparison circuit (IC2) supplies power to
each control IC (IC3, IC6, IC7) when the input voltage
falls within the appropriate range.
The power supply turns on when the input voltage is
within the range of +9.8 V to +19.0 V. After the power
supply turns on, it continues to operate until the input
voltage falls below the lower limit (+7.5 V).
Each output is connected to a short-circuit detection
circuit. If any of the outputs are short-circuited or if a
signal is not output due to some error, the short-circuit
detection circuit outputs the H SHUT DOWN signal.
This signal causes the supplied UNREG +12 V to be cut
off at the source.
+5 V, +3.3 V, and +1.8 V use a step-down chopper
circuit, and _5 V uses an inverse chopper circuit.
+12 V uses a rising and falling voltage circuit and can
control output voltage in a range of +10.0 V to +13.5 V
with the control voltage (BRIGHT ADJ) from the PR-292
board.
CPU (IC600) performs parallel communication with
FPGA, controls the character generator (IC601) and D/A
converter (IC614), and performs IIC communication with
the panel module.
The A/D input port connects to the signal wires for
brightness, contrast, peaking, and volume level and
controls these parameters.
The D/A converter controls the dimmer for the external
tally lamp and the voltage for the backlight power supply.
IIC communication with the panel module controls PWM
modulated light for the backlight and the black insertion
rate.
Data such as luminance and color temperature adjustment
data are saved on EEPROM (IC606) on the board.
FPGA can be upgraded for E-Production through CN14.

3. Check the ROM version.
1-5-2. Writing and Rewriting PLD Internal
Data
The device is equipped with a PLD (Programmable Logic
Device) that can be written and rewritten using the eProduction (EPR) method.
When replacing the following parts or upgrading the PLD
version, contact your local Sony Sales Office/Service
Center.
n
The part number of the PLD (or the ROM for the PLD)
noted in “Spare Parts” is for a part with no data written.
When you need to replace any part, write data using the
steps on the next page.
For a PLD that has a program operating on the externally
connected ROM, when a part in the PLD is defective, if
you replace only the defective part, you do not have to
rewrite the data.
About e-Production
. When writing or rewriting the PLD internal data,
1. Standard tools (cables) can be used.
2. Standard software (PLD Download Tool) can be
used.
. The PLD internal data is managed on the Sony database
server as a Project file (E_xxx_xxx_xx_xx).
. The standard connector (EPR connector) for writing
PLD internal data on the board is equipped. “EPR” is
displayed on the board.

Step 1. Prepare the Project file.
n
Download the Project file from the Sony database
server.
Step 2. With the power of the device turned off, connect
the parallel port on the PC and the EPR connector
on the target board with the PLD download tool
(cable).
Step 3. Turn on the power of the device.
Launch the PLD Download Tool software, and

1-9. Fuse and IC Link Replacement
1-10. Unleaded Solder
w
The fuse and IC link are critical parts to safe operation.
Replace the components with Sony parts whose part
number appear in the manual published by Sony. If the
components are replaced by any parts other than the
specified ones, this may cause a fire or electric shock.
c
If a fuse or IC link is replaced while the main power is kept
on, this may cause electric shock.
Before replacing fuse or IC link, not only turn off the
POWER switch but also remove the power cable that is
connected to the DC IN connector.
The RE-237 board is equipped with fuse. The PR-292
board is equipped with IC link.
Any an excessive current flow due to abnormality inside
the equipment, the fuse and IC link blow. If a fuse or IC
link blows, turn off the main power of the equipment once
and inspect inside of the equipment and remove the cause
of excessive current. After that, replace the fuse and/or IC
link.
Boards requiring use of unleaded solder are printed with a
lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come
printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
m
. Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recommended to use the soldering iron having a temperature
regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.
