1.3 Turn On/ Turn Off Function
(1) Turn On function: User can touch “Power” key, or use remote controller to turn on the projector. When MCU
receives the command, it will start the power up sequence for DDP ASIC. Color wheel motor will spin up first,
and then Lamp enable signal will be sent to Ballast board. After Lamp was ignited, LAMPLIT signal will be fed
back to DDP ASIC. It will reset itself and start to send the formatting data to DMD chip. At the mean time MCU
reset the cooling circuit and let it working. Then the whole system is warming up.
(20 Turn Off function: User can touch “Power” key, or use remote controller to turn off the projector. When MCU
receives the command, it will start the power down sequence. DDP ASIC will be reset off, and then Lamp enable
signal will be turn off. The Lamp will be turned off. MCU will remain the cooling circuit operation for two
minute in order to cool down the lamp module. After the cooling procedure is end, then the whole system goes
to standby mode.
