º POWER Light
When the TV is turned ON, the Power Light will first blink to indicate that the television lamp is warming
up. This light will be ON during normal operation. When the TV is turned OFF, the Power Light will blink
to indicate that the television lamp will be cooling down and the light will eventually turn off.
¾ TEMP Indicator
This light is off during normal operation. If this indicator is lit, the optic unit is too hot. If this indicator is
blinking, the cooling fan has stopped. Please call service. The optic unit has an air filter that may become
clogged over time. The internal termperature will increse which will trigger the temperature sensor to display
an On-Screen warning. After 5 minutes, the lamp will turn off, then the TV will turn off with the TEMP LED On.
µ LAMP Indicator
This light is off during normal operation. If light is lit, the lamp has failed. See page 56-59 for lamp
replacement procedure. Consult your Hitachi dealer for proper part. If light is blinking, lamp cover is not
assembled securely after replacement.
