For continued safety, replace safetycritical components only with manufacturer's recom-mended parts.1. Units of components on the schematic diagramUnless otherwise specified.1) All resistance values are in ohm. 1/6 W, 1/8 W (refer toparts list).Chip resistors are 1/16 W.K: K(1000), M: M (1000K)2) All capacitance values are in µF, (P: PF).3) All inductance values are in µH, (m: mH).4) All diodes are 1SS133, MA165 or 1N4148M (refer to partslist).2. Indications of control voltageAUX : Active at high.AUX or AUX(L) : Active at low.3. Interpreting Connector indicationsNote: If the voltages are not indicated on the schematicdiagram, refer to the voltage charts.12 32.5(5.0)1.8PB and REC modes(Voltage of PB and REC modesare the same)PB modeREC mode4. Voltage measurement1) Regulator (DC/DC CONV) circuitsREC : Colour bar signal.PB : Alignment tape (Colour bar). : Unmeasurable or unnecessary to measure.2) Indication on schematic diagramVoltage indications for REC and PB mode on the sche-matic diagram are as shown below.6. Indication of the parts for adjustmentsThe parts for the adjustments are surrounded with the circleas shown below.7. Indication of the parts not mounted on the circuit board“OPEN” is indicated by the parts not mounted on the circuitboard.R216OPEN1231231231423Removable connectorWire soldered directly on boardNon-removable Board connectorBoard to BoardConnected pattern on boardThe arrows indicate signal pathNote: The Parts Number, value and rated voltage etc. in the Schematic Diagram are for references only. When replacing the parts, refer to the Parts List.CIRCUIT BOARD NOTES1.

ALL COMPONENTS SHOULD BEREPLACED ONLY WITH TYPES IDENTICAL TO THOSEIN THE ORIGINAL CIRCUIT. SPECIAL COMPONENTSARE SHADED ON THE SCHEMATIC FOR EASYIDENTIFICATION. THIS CIRCUIT DIAGRAM MAYOCCASIONALLY DIFFER FROM THE ACTUAL CIRCUITUSED. THIS WAY, IMPLEMENTATION OF THE LATESTSAFETY AND PERFORMANCE IMPROVEMENTCHANGES INTO THE SET IS NOT DELAYED UNTILTHE NEW SERVICE LITERATURE IS PRINTED.1. Shaded( ) parts are critical for safety. Replace onlywith specified part number.2. Voltages are DC-measured with a digital voltmeterduring Play mode.IMPORTANT SAFETY NOTE :Standard schematic diagramsPower (SMPS) sectionSHEET 12-9 2-10A12345BCDEFGSystem (MPEG) sectionSHEET 22-11 2-12A12345BCD EFGServo control sectionSHEET 32-13 2-14A12345BCDEFGAV/Jack sectionSHEET 42-15 2-16
