Be sure to read this manual before servicing. To assure safety from fi re, electric shock, injury, harmful radiation
and materials, various measures are provided in this HITACHI Plasma display.
Be sure to read cautionary items described in the manual to maintain safety before servicing.
Service Warning
1. Since Panel Module and front Filter are made of glass, handling the broken Module and Filter shall be
taken care suffi ciently in order not to be injured.
2. Replacing work shall be started after the Panel Module and the AC/DC Power supply become suffi ciently
cool.
3. Special care shall be taken to the display area in order not to damage its surface.
4. The Panel Module shall not be touched with bare hand to protect its surface from stains.
5. It is recommended to use clean soft gloves during the replacing work in order to protect not only the display area of the Panel Module but also a serviceman himself.
6. The Chip Tube of Panel Module (located upper left of the back and surrounded by frame) and fl exible
cables connecting Panel glasses to drive circuit PWBs are very weak, so shall be taken care suffi ciently
not to break. If you break Chip Tube, the Panel doesn’t display anything forever.

of User’s Manual.
Prevent the electric shock.
Please take care during working because
monitor has high voltage part and power
supply part.
Possible to die if you tough to these place
by miss take.
Please disconnect power plug during
overhaul, reassemble or change parts.
You will die or take damage by electric
shock if you touch to live part.
Use recommended components.
Please use to same characteristic compo-
nent, which is same as previous for your
safety and keep reliability especially marked
by in parts list and circuit diagram.
It is reason of electric shock or fire if you
use non-recommended component.
Should be kept same style of wiring or component.
Monitor uses tubes or tapes, which made
by insulator, and some components are
keep distance from surface of PWB for
safety.
Internal leads kept from hot part or high voltage
part by clamper or styling, so please return to
original condition for prevent to electric shock
or fire.
Should be done safety check after finished.
Every part (removed screws, component
and wiring) should be returned to previous
condition.
Check around repair position for make
damage by miss take and measure the
insulated impedance by meg-ohm meter.
Confirm the value of impedance, that
value is more than 4M ohm.
It is reason for electric shock or fire if that
value is less than 4M ohm.
Nobody can check and repair to the code
and combination circuit of HDCP.
Never remove the shield case, which is
assembled to the code and combination
circuit of HDCP.

PRECAUTIONS
How to clean the plasma screen panel of the monitor
Before cleaning the monitor, turn off the monitor and disconnect the power plug from the power outlet.
To prevent scratching or damaging the plasma screen face, do not knock or rub the surface with sharp or hard
objects. Clean the screen with a soft cloth moistened with warm water and dry with a soft cloth. If it is not
enough, then use a cloth with mild detergent. Do not use harsh or abrasive cleaners.
How to clean the cabinet of the monitor
Use a soft cloth to clean the cabinet and control panel of the monitor. When excessively soiled dilute a neutral
detergent in water, wet and wring out the soft cloth and afterward wipe with a dry soft cloth.
Never use acid/alkaline detergent, alcoholic detergent, abrasive cleaner, powder soap, OA cleaner, car wax,
glass cleaner, etc. especially because they would cause discoloration, scratches or cracks.
The 37-inch color plasma display panel, with a resolution of 1024 (H) x 1024 (V) pixels, creates a high-definition,
large-screen(aspect ratio : 16:9) and low-profile flat display. Free from electromagnetic interferences from geomagnetic sources and ambient power lines, the panel produces high-quality display images free from color misconvergence and display distortion.
High Performance Digital Processor
A wide range of input signals can be handed,including composite, component,and HDMI.High Definition Digital Processor creates the fine-textured image with dynamic contrast. In addition, it corresponds to a broad array of personal computer signals, from 640 x 400 and 640 x 480 VGA to 1600 x 1200 UXGA.(Analog Input)
Easy-to-use remote control and on screen display system
The remote control included eases the work of setting display controls. Further, the on-screen display system,
displays the status of signal reception and display control settings in an easy-to-view fashion.
Power saving system
The International ENERGY STAR power saver feature saves power consumption automatically when input signals are not available.
When connected to a VESA DPMS-compliant PC, the monitor cuts its power consumption while it is idle.
Connecting to an Audio Visual Device
• Two composite/S terminal*1,three composite terminal*2, two component terminal*2, a HDMI terminal and
a photo input terminal have been added. A composite video output terminal is also provided as a
monitoring output.
*1
A composite/S terminal = A side input
*2
If two composite terminal and two component terminal are used at the same time, the component terminal
would govern.
• A wide range of devices can also be connected besides personal computers.
• A RGB input is possible to switch to component signal from the Menu screen.
Power Swivel Feature
It allows to turn the plasma display left or right within ± 30 degree using the remote control.

This product uses lead free solder (unleaded) to help preserve the environment. Please read these instructions
before attempting any soldering work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free
solder can splatter at high temperatures (600˚C).
Lead free solder indicator
Printed circuit boards using lead free solder are engraved with an "F."
Properties of lead free solder
The melting point of lead free solder is 40-50˚C higher than leaded solder.
Servicing solder
Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended.
Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not taking
these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.)
Precautions when using leaded solder
Remove all lead free solder from soldered joints when replacing components.
If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the lead
free solder has been completely melted (do not apply the soldering iron without solder).
Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead free solder is higher than leaded solder. Use a soldering iron that maintains a high
stable temperature (large heat capacity), and that allows temperature adjustment according to the part being
serviced, to avoid poor servicing performance.
Recommended soldering iron:
Soldering iron with temperature control function (temperature range: 320-450˚C)
AUDIO PWB, JOINT PWB, Swievel PWB, HDHI PWB, control PWB
VIDEO PWB
TUNER PWB
Readjustment Power supply voltage
When a PANEL or a Power Unit is exchanged, power supply voltage needs to be adjusted. Please adjust to
make the values of Va and Vs of as should on the label currently stuck on the panel back upper parts.Adjustment is performed by VR in the power supply unit. Please refer to the procedures of “Va” and “Vs” adjustments
on 23page.

Item Power Unit Vs, Va Adjustment
Applicable Model All models
Preparation Procedure
(1) Turn on the set and perform
pre-heat run more than 1 min
on burn-in screen.
(2)
Receive full back pattern signal
(or Video silence signal;
but it will be automatically turned off
after a few seconds by power save function.)
(3) Connect voltmeter leads to Vs
(or Va) and GND test points of the power unit.
37PD7800 (PW2)
(1) Turn Vs ADJ to adjust Vs voltage
to be within ±0.1V of the value
specified in the label on the panel.
Adjust within ± 1V at Vs1
Adjust within ± 0.1V at Vs2
(2)
Turn Va ADJ to adjust Va voltage
to be within ±0.2V of the value specified
in the label on the panel.
Adjust within ± 1V at Va1
Adjust within ± 0.2V at Va2
Reconfirm that Vs voltage remains within
(3)
±0.1V of the specified value.
Readjust if it’s outside of the margin.
