6. Troubleshooting
6. 1. Power/Light source/Temperature indicators
6. 1. 1. Power indicator
• Indicate the status of the power. Check the status of the power indicator <ON (G)/STANDBY (R)> before operating the
projector.
Light source indicator <LIGHT1>
Light source indicator <LIGHT2>
Temperature indicator <TEMP>
Power indicator <ON (G)/STANDBY (R)>
Red
Lit
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
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 [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].
g
The [PROJECTOR SETUP] menu → [QUICK STARTUP] is set to [ON].
f
The projector may not operate when the light source indicators <LIGHT1>/<LIGHT2>
or the temperature indicator <TEMP> are blinking.
Green
Lit
Projecting.
Orange
Lit
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 “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
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
Projector status
Off
The main power is switched off.

6. 1. 2. Light source indicators
• If a problem occurs inside the projector, the light source indicators <LIGHT1>/<LIGHT2> will inform you by lighting or blink-
ing.
6. 1. 3. Temperature indicators
• If a problem occurs inside the projector, the temperature indicator <TEMP> will inform you by lighting or blinking.
Indicator status
Status
Solution
Lighting in red
Some of the elements of the light
source are defective and the light
output has decreased.
f
Turn the <MAIN POWER> switch to <OFF>, and turn on the
power again.
Blinking in red
(1 time)
The light source 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.
Blinking in red
(2 times)
The light source does not light up,
or the light source turns off while the
projector is in use.
f
Turn the <MAIN POWER> switch to <OFF>, and turn on the
power again.
Blinking in red
(3 times)
Note
f
If the light source indicators <LIGHT1>/<LIGHT2> are still lit or blinking after taking the measures, set the <MAIN POWER> switch to
<OFF>, and repairs.
f
The light source indicator corresponding to the light source being lit will light up in green if the projector is in projection mode and there is no
indication of problem by lighting or blinking in red.
f
The function to detect the projector lens may or may not exist depending on the country or region where you purchased the product.
Indicator status
Lighting in red

Status
Warm-up status
Internal temperature is high
(warning).
Internal temperature is high
(standby status).
The cooling fan has
stopped.
Cause
f
Did you turn on the power
when the temperature
was low (around 0 °C
(32 °F))?
f
Is the air intake/exhaust port blocked?
f
Is the room temperature high?
―
Solution
f
Wait at least five minutes
in the current status.
f
Use the projector
in an appropriate
operating environment
