CIRCUIT BOARDS LOCATION A Board C Board 4-3. SCHEMATIC DIAGRAM 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.

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: -
