Technicolor - Thomson CDP-CX57 service manual Singapore model

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

Note on Schematic Diagram:

•All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

•All resistors are in Ω and 1/4 W or less unless otherwise specified.

•¢ : internal component.

•C : panel designation.

•U : B+ Line.

•V : B– Line.

•H : adjustment for repair.

•Voltages and waveforms are dc with respect to ground under no-signal conditions.

no mark: PLAY

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances.

•Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc- tion tolerances.

•Circled numbers refer to waveforms.

•Signal path. J : CD c : digital out

•Abbreviation

AED : North European

AUS : Australian model.

CND : Canadian model.

E2	: 120 V AC Area in E model.
E3	: 240 V AC Area in E model.
SP	: Singapore model.

Note on Printed Wiring Boards:

•X : parts extracted from the component side.

•Y : parts extracted from the conductor side.

•¢ : internal component.

•b: Pattern from the side which enables seeing.

• : Solder bridge.
