5. 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.
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 thepower 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.

(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 ask your dealer for 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.
5. 1. 3. Temperature indicators
• If a problem occurs inside the projector, the temperature indicator <TEMP> will inform you by lighting or blinking.
