EXPLANATION OF CIRCUIT
5. KEY PCB
KEY PCB has various keys and remote control dimmer sensor port.
a. 3V is supplied to IC503 by IC540, key SW is taken in, and assignment of
remote control and the data of main part key are performed.
6. DVD PCB
a. DVD DECODER
IC701 communicates with microcomputer, and playbacks DVD by DVD DECODER.
b. VIDEO DAC
IC751 outputs DVDRGB, Y/C signal and VIDEO signal by DVD VIDEO DAC
c. AUDIO DAC
IC781 outputs DVD audio through BUFFER(IC791) by DVD AUDIO DAC.
In DVD MODE, the power supply is supplied to DVD BLOCK and SERVO PCB.
DVD BLOCK from Q611 and Q613. 5V is supplied to SERVO PCB from Q120.
The DVD signal from the microcomputer is Hi, and 3.3V and 5V are supplied to
(SERVO PCB)
1. RF AMP PART(IC1101)
For the signal read by PICKUP, AMP is performed, and equalizing of playback RF
signal and error signal required for each SERVO are generated.
2. DSP PART(IC 1 201)
Digital signal processing of the signal from RF AMP is performed, and control
signals of PICK UP, SPINDLE MOTOR, and FEED MOTOR etc are outputted.
Recovery and correction of RF signal are also performed.
3. ATAPII/F PART(IC1250)
It communicates by ASIC and ATAPII/F in NAVI PCB.
4. MICROCOMPUTER PART(IC1151)
is controlled .
When in NAVI MODE, 5V power supply is supplied, and operation of DVD BLOCK
