The service Precaution:The area enclosed by this line ( ) is directly connectedwith AC mains voltage. Whenservicing the area, connect anisolating transformer betweenTV receiver and AC line to elim-inate hazard of electric shock.
Product safety notice:Product safety should be consideredwhen a component replacement ismade in any area of a receiver.Components indicated by a mark /!\ inthis circuit diagram show componentswhose values have special significanceto product safety. It is particularly rec-ommended that only parts specified onthe part service manual be used forcomponents replacement pointed outby the mark.
Circuit diagram notes :1. All resistance values are in ohms, K=1,000, M=1,000,000.2. All resistance rated wattages are 1/6W unless otherwise
noted.3. Excepting electrolytic capacitors, all capacitance values of
less than 1 are expressed in µF and more than 1 are pF.4. All capacitance rated voltages are 50V unless otherwise
noted.5. All inductance values are in µH.6. Voltage readings taken a digital voltmeter are from point indi-
cated chassis ground. Voltage readings taken by using acolour bar signal are with all controls at normal position.Some voltages may vary with signal strength.
7. Waveforms were taken with colour bar and controls adjustedfor normal picture. Waveforms were taken by using a wideband oscilloscope and a low capacity probe.
