SECTION 4

CHARTS AND DIAGRAMS

 SCHEMATIC DIAGRAM NOTES

• Schematic safety precaution

! Parts are safety related parts. When replacing them, be sure to use the specified parts.

• Voltage and waveform measurements

Voltage: Measured with digital voltmeter in DC range;

iris closed in REC mode. Value in ( ) is indicated only in the case PB voltage is different from that in REC mode.

Waveform: Gray scale illuminated at more than 4000 lux at

3200K lighting.

• Unit of value

Unless otherwise specified

1) Resistance is in Ω (1/6 W)

2) Capacitance is in µF

3) Inductance is in µH

• Expression of wiring

As the following circuit diagram is divided to print on some sheets, such an indication as the following is found in the case the wiring extends over two or more divided sections.

1) Circuit diagram divided into two or more sections:

Board Board Name

16 19 31 32 10

SE DPR SS/CP AUDIO/LCD DV MAIN

Number of

divided sections

1/2 – 2/2 1/4 – 4/4 1/2 – 2/2 1/2 – 2/2 1/7 – 7/7

• Wiring of connector

(Example)

CN11

1

To CN11

2

(P. 4-6)

11

ISB

In the above example, CN11 is connected with CN11 on

11 ISB board.

• Signal flow on the diagram

The following allow marks indicate the specified signal paths respectively.

: Recording or EE signal path : Playback signal ptah : Recording and Playback signal path

• Others

In regard of a board assembly whose circuit is composed of multilayered board patterns such 4- or 6-layered patterns, board patterns of the power supply lines and grounding lines are omitted in this section.

Note: For detail of each electrical part, refer to Section 6

“ELECTRICAL PARTS LIST” by it symbol number.

 REPLACING SURFACE MOUNT “CHIP” COMPONENTS

• Some resistors, shorting jumpers (0 resistance), ceramic capacitors, transistors, and diodes are chip parts. These chip parts cannot be reused after they are once removed.

• Chip resistors used in some circuits are of high precision type having little error in resistance. To demonstrate the full capacity of this set, place an order for proper parts referring to the diagrams and parts lists in the section 5.

• Soldering cautions:

1) Do not apply heat for more than 3 seconds.

2) Avoid using a rubbing stroke when soldering.

3) Discard removed chips; do not reuse them.

4) Supplementary cementing is not required.

5) Use care not to scratch or otherwise damage the chips.

2) Indication of wiring which extends to another section: (Example)

A)

This indication that wiring extends to “2/3” of the diagram.

DSP_HD 2/3

Signal name

In the above case, the end of the wiring is connected to the “DSP_HD” on the 2nd section of the diagram.

B)

This indication that wiring extends to “DV I/O” section of the diagram.

FRP DV I/O

Signal name

In the above case, the end of the wiring is connected to the “FRP” on the “DV I/O” section of the diagram.

Two digits show resistance of R1 in abbreviation.
