4-2. SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(For printed wiring boards)
•
: Uses unleaded solder.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated)
• Through hole is omitted.
• There are a few cases that the part printed on diagram
isn't mounted in this model.
• C : panel designation
(For schematic diagrams)
• All capacitors are in µF unless otherwise noted. pF : µµF.
50V or less are not indicated except for electrolytics and
tantalums.
• All resistors are in ohms, 1/4 W (Chip resistors : 1 /10 W) un-less
otherwise specified.
kΩ=1000Ω, MΩ=1000kΩ.
• 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, be-
cause it is damaged by the heat.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• 2 : non flammable resistor
• 5 : fusible resistor
• C : panel designation
•
f
: internal component
• C : adjustment for repair
•
G
: IN/OUT direction of (+/–) B line
• U : B+ Line
• V : B– Line
• Circled numbers refer to waveforms.

• Readings are taken with a color-bar signals on DVD reference
disc.
• Readings are taken with a digital multimeter (DC 10MΩ).
• Voltage variations may be noted due to normal production tol-
erances.
Note :
The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
Note :
Les composants identifiés par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par une pièce portant le numéro
spécifié.
When indicating parts by reference number, please
include the board name.
