4-2. SCHEMATIC DIAGRAMS
(ENGLISH)
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(For schematic diagrams)
• All capacitors are in µF unless otherwise noted. pF : µ
µF. 50 V or less are not indicated except for electrolytics
and tantalums.
• Chip resistors are 1/10 W unless otherwise noted.
kΩ=1000 Ω, MΩ=1000 kΩ.
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
capacitor, Because it is damaged by the heat.
• Some chip part will be indicated as follows.
Example
Kinds of capacitor
• Constants of resistors, capacitors, ICs and etc with XX
indicate that they are not used.
In such cases, the unused circuits may be indicated.
• Parts with ★ differ according to the model/destination.
Refer to the mount table for each function.
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• Signal name
XEDIT → EDIT
• 2: non flammable resistor
• 5: fusible resistor
• C: panel designation
• A: B+ Line
• B: B– Line
J
• : IN/OUT direction of (+,–) B LINE.
• C: adjustment for repair.
• A: not use circuit
(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the
measurement points and ground when camera shoots
color bar chart of pattern box. They are reference values
and reference waveforms.
(VOM of DC 10 MΩ input impedance is used)
• Voltage values change depending upon input
impedance of VOM used.)

When indicating parts by reference number, please
include the board name.
The components identified by mark 0 or dotted line with
mark 0 are critical for safety.
Replace only with part number specified.
Les composants identifiés par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par une pièce portant le numéro
spécifie.
