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 10MΩ 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 3
blocks. Each block is named by its function and
block "number". eg: Processor/Audio/Tuner/Jack
(Block 001).
Joint connection between boards can be identified
using the block number followed by the grid's guide.
Meaning: Block 001 joint "+B" is connected to Block
002 joint "+B" located at grid 16F.
