• ANALOG SUB, DIGITAL, D-AMP and REG boards are
multi-layer printed board.
However, the patterns of intermediate layers have not
been included in this diagrams.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF

• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
– VIDEO, S-VIDEO boards –
no mark : VIDEO 1 mode (NTSC color bar input)
– Other boards –
no mark : TUNER
• 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.
