SERVICE MANUAL ED-X3270A(C3XM3E)
Caution
Be sure to read this manual before servicing. To assure safety from fire, electric shock, injury, harmful
radiation and materials, various measures are provided in this Hitachi Multimedia LCD Projector. Be
sure to read cautionary items described in the manual to maintain safety before servicing.
Service Warning
1. When replace the lamp, to avoid burns to your fingers. The lamp becomes too hot.
2. Never touch the lamp bulb with a finger or anything else. Never drop it or give it a shock. They may
cause bursting of the bulb.
3. This projector is provided with a high voltage circuit for the lamp. Do not touch the electric parts of
power unit (main), when turn on the projector.
4. Do not touch the exhaust fan, during operation.
5. The LCD module assembly is likely to be damaged. If replacing to the LCD module assembly, do
not hold the FPC of the LCD module assembly.
6. Use the cables which are included with the projector or specified.

6. Service points
Lead free solder [CAUTION]
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)
Recommended temperature range per part:
Part Soldering iron temperature
Mounting (chips) on mounted PCB 320°C±30°C
Mounting (chips) on empty PCB 380°C±30°C

Before Replacing the LCD / Lens Prism
You should not replace separately the parts of the liquid crystal LCD / Lens Prism because it works properly
only when used together. Therefore, regarding these parts, you can either replace part , LCD / Lens Prism
assembly, or send the whole unit LCD / Lens Prism assembly back to Hitachi, where we will replace the
malfunctioning part, recondition the device and send it back to you.

Resetting the Lamp Timer
Reset the lamp timer after replacing the lamp. When the lamp has been replaced after the LAMP indicator is
red, or the CHANGE THE LAMP message is displayed, complete the following operation within ten minutes
of switching power ON. The power will be turned off automatically in over 10 minutes.
1. Switch power ON, and select the LAMP TIME on the OPTION menu.
2. Depress the RESET button for at least 3 seconds while lamp time is being displayed.
The reset menu will then appear.
3. Select RESET on the menu with the button, and wait until the timer display is cleared.
NOTE:
Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing the

Notice of AUTO adjustment
Use of AUTO adjustment with the image through RGB input optimizes VPOSI, HPOSI, HSIZE and HPHASE
automatically.
In case that projected image has dark tone around its peripheral, AUTO operation sometimes makes artifacts
in the image, shifts capture area and so on. Those failures are caused by period of image data is not exactly
distinguished to period of blanking on signal processing.
To avoid such phenomena, AUTO function should be used with the full size picture that has bright tone on its
peripheral.
Image when AUTO operates correctly Image when AUTO fails.
Noting image of top or bottom lines.
Shift of the image to East or West.
Artifacts on image. Etc.
Note
1) The phenomenon at the failure of AUTO adjustment depends on resolution of input source, scene of
picture etc.
2) There is no failure above in AUTO with video source through VIDEO, S-VIDEO or COMPONENT input. The
reason is why recognition of input signal's standard does not need to search the capture range from input
signal itself.

Setup of a Cooling Fan Speed
When using this projector in the place where altitude is high, we recommend you to set a cooling fan's speed
as "HIGH". It is because the cooling efficiency of a projector falls and the temperature inside a projector rises
easily in such a place, since the density of air becomes low.
Setting Method of Cooling Fan Speed
1. Select the "FAN SPEED" on the OSD using button " " by the SERVICE MENU.
2. Select the "HIGH" on the OSD using the button " ". To reset this setup, select the "NORMAL" using the
button " ".
3. The OSD will be ended by no operation for 10 seconds or change of input signal. To end immediately, use
one of buttons except buttons " ", " ", " ", " ".
NOTE:
The "HIGH" mode makes the fan noisy than "NORMAL" mode.
The recall of factory setting sets the fan speed to "NORMAL" mode. You must set the fan speed after recall
of factory setting if you need "HIGH" mode.
