4. 3. Security password
4. 3. 1. Control device password
•To revert to the factory default password (AAAA), perform the following operations while the screen asking for a control
device password input is displayed.
1. Press the [AUTO SETUP] button on the remote control or on the control panel for more than 3 seconds.
2. Press the [▼] button for more than 3 seconds.
The password will be initialized.
• The password will also be initialized when performing the menu [ALL USER DATA] from [PROJECTOR SETUP]
- [INITIALIZE].
4. 3. 2. Initial security password
•Initial password : Press [p u q t p u q t] button sequentially and press [ENTER] button.
•If the initial password has been changed, ask user to have it.
4. 2. 3. Repair
1. Energization check and adjustment, after assembling the lighting block completely.
• Before turning on the power, please make sure that the lighting block is completely assembled.
• The service engineer who works on this model and also other people who are in the same room need
to wear the laser safety glasses for avoiding the laser irradiation just in case.
2. Before repair, make sure to turn off the main power and unplug the power cord from the power outlet.
* When replacing the print board, the internal electrical parts can be broken by the static electricity of clothes or human
body. Be careful of static electricity and wear the anti-static electricity gloves.
3. After repairing, please check the gradation (10step or the gray scale) test pattern or moving image.
Also, please check that it is normal on a self check screen.
4. Do handling and safekeeping carefully because the user setup information remains in the projector.
4. 2. 4. Replacement of printed circuit board
1. When the replacement of A-PCB (assembly) is needed, back up the memory information such as adjustment data from the
old board to PC with the service software. Then transfer this data to the new A-PCB.
For more information refer to the SECTION 3 "Adjustment".
• If you cannot transfer the data by using the software, remove the [IC3711] on the original board and mount it on
the new board.
2. When replacing the [A] or [DG] printed circuit board, write the latest version of main firmware again to make consistency
between Main and FPGA firmware. Each FPGA firmware is updated when updating of Main firmware at the same time.
• When [A]-P.C.Board is replaced, the MAC address of wired LAN will be changed. Explain it to the customers
in advance.

The power is switched off. (standby mode)
Projection will start when the power on <b> button is pressed.
f
The setting of the projector is as follows.
g
The [PROJECTOR SETUP] menu → [QUICK STARTUP] is set to [OFF].
f
The projector may not operate when the light source indicators <LIGHT1>/<LIGHT2>
or the temperature indicator <TEMP> are blinking.
Blinking

Projection will start when the power on <b> button is pressed.
f
The setting of the projector is as follows.
g
The [PROJECTOR SETUP] menu → [QUICK STARTUP] is set to [ON].
f
The indicator will change to a red light when the specified time has elapsed after the
projector enters the standby mode if the projector is set as following.
The specified time is the time set in the [PROJECTOR SETUP] menu → [QUICK
The specified time is the time set in the [PROJECTOR SETUP] menu → [QUICK
STARTUP] → [VALID PERIOD].

The projector is preparing to switch off the projector.
The power is switched off after a while. (Changes to the standby mode.)
Note
f
While the power indicator <ON (G)/STANDBY (R)> lights in orange, the fan is running to cool the projector.
f
For approximately five seconds after the projector is turned off, the indicator does not light up even if the power is turned on. Turn on the
power again after the power indicator <ON (G)/STANDBY (R)> lights/blinks in red.
f
The projector consumes power even in standby mode (power indicator <ON (G)/STANDBY (R)> lights/blinks in red). Refer to Operating
Instructions “Power consumption” for the power consumption.
f
When the projector receives the signal from the remote control, the power indicator <ON (G)/STANDBY (R)> will blink in the following
color according to the status of the projector.
g
g
When the projector is in projection mode: Green
g
When the projector is in standby mode: Orange
However, if the [PROJECTOR SETUP] menu → [STANDBY MODE] is set to [ECO], the indicator will stay lit in red and will not blink if
the projector is in standby mode.
f
The power indicator <ON (G)/STANDBY (R)> will blink slowly in green while the shutter function is in use (shutter: closed), or while the
function of the [PROJECTOR SETUP] menu → [NO SIGNAL LIGHTS-OUT] is operating and the light source is turned off.

Indicator status
Status
Solution
Blinking in red
(1 time)
The light source on one side is turned
off since the projection lens cannot be
detected.
f
Turn off the power and mount the projection lens again.
f
Turn the <MAIN POWER> switch to <OFF>, and turn on the power again.
The light source indicators <LIGHT1>/<LIGHT2> may not light up or blink.
Blinking in red
