The LAMP indicator lights and LAMP REPLACE indicator is
flashing
If the LAMP_SWIN signal is not supplied to the Lamp Ballast, the
projector cannot be turned on. Check the follows;
- Check the lamp cover and the lamp cover switch (SW901).
SW901--open: Abnormality
- Check the signals LAMP_SWIN, CHO_TXD, CHO_RXD output from
IC9885.
The POWER and LAMP indicators do not light
If the POWER and LAMP indicators are not lighting, check the
Fuse (F601) and Thermal switch (SW902) in the primary circuit
and SB_5V of standby power supply circuit.
- Fuse opens when the primary circuit has a error.
- Thermal switch opens when surrounding temperature of lamp
reaches around 115ºC.
Check that IIC Bus
signals are correct.
No Power
Check that POWER FAIL sig-
nals are correct.
L : Abnormality
LAMP indicator lights and other indicators blink
If the LAMP indicator is lighting and other indicators are blink-
ing, the projector detects an abnormal inside the projector.
Check following points;
- Check the secondary power supply. Error on the low power
voltage
- Check the fan operation. Error on the fan.
- Check the filter cartridge detecting switch (SW1891).
SW1891 open: Error
- Check the signal FILTER_DET supplied to IC301.
FILTER_DET Low: Error
Check that the Power on/off signals are correct.
- POWER_SW H: Network Standby / L: Eco Standby
- LAMP_DC_ON H: Power-on
