4-2. CIRCUIT BOARDS LOCATION
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.
k
Ω = 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 M
 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
