Check that PFC circuit on/
off signals are correct.
Check that the Lamp bal-
last on/off signals are
correct.
Check the temperature
switches.
Thermal switches will open at
around 80ºC.
Is fuse (F901) blown?
Fuse may be opened
when either LAMP indi-
cator or POWER indicator
does not light. Check
the fuse.
For safety, replace it with
a new fuse of the same
type
Is the lamp cover attached correctly?
When the lamp cover is removed
or not attached correctly, the
projector cannot be turned on.
Check the lamp cover and the lamp
cover switch (SW902).
SW902--open: Abnormality
Are the LAMP indicator (red) and
POWER indicator (green) light?
If the LAMP and POWER indicators
are not light, check the primary
circuit and SS6V of standby power
supply circuit.
Check that Vcc voltages
are correct.
Check that IIC
Bus signals are
correct.
No Power
Check 12V
for PFC.
Check that POWER FAIL sig-
nals are correct.
L : Abnormality
Check that POWER ON/OFF signal
(DC_ON) is correct.
