4-3. SCHEMATIC DIAGRAM INFORMATION
Note:
• All capacitors are in µF unless otherwise noted.
• All electrolytic capacitors are rated at 50V unless otherwise
noted.
• All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
• Indication of resistance which does not have rating
electrical power is as follows.
Pitch: 5 mm
Rating electrical power 1/4W (CHIP: 1/10W)
• : nonflammable resistor.
• : fusible resistor.
• ¢ : internal component.
• : panel designation or adjustment for repair.
• All variable and adjustable resistors have characteristic
curve B unless otherwise noted.
• Readings are taken with a color-bar signal input.
no mark : Common
( ) : PAL
[ ] : NTSC 3.58
• Readings are taken with a 10 MΩ digital multimeter.
• Voltage are dc with respect to ground unless otherwise
noted.
• Voltage variations may be noted due to normal
production tolerances.
• All voltage are in Volt.
• ✽ : Cannot be measured.
• Circled numbers are waveform references.
• : B +bus.
• : B –bus.
• k : signal path.
Note: The reference number which starts with Wxxx
(eg: W003) indicates a wire to wire connection.
Note: Components marked as XX are not fitted on this
model.

Note: The component identified by shading and
mark ! are critical for safety. Replace only
with part number specified.
Note: “A” board schematic diagram is divided into 6 blocks.
Each block is named by its function and block
“alphabet”. eg: Processor (Block A)
Joint connection between boards can be identified
using the block alphabet followed by sequence
numbering.
eg: -<HOUT-DEFL (A10) To D11
Meaning: Block A joint A10 is connected to Block D
joint D11
