• Caution when replacing chip parts.

New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
capacitor, Because it is damaged by the heat.

• Some chip part will be indicated as follows.

• Constants of resistors, capacitors, ICs and etc with XX

indicate that they are not used.
In such cases, the unused circuits may be indicated.

• Parts with 

★

 differ according to the model/destination.

Refer to the mount table for each function.

• All variable and adjustable resistors have characteristic

curve B, unless otherwise noted.

• Circled numbers refer to waveforms.
(Measuring conditions voltage and waveform)

• Voltages and waveforms are measured between the

measurement points and ground when camera shoots
color bar chart of pattern box.  They are reference values
and reference waveforms.
(VOM of DC 10 M

Ω

 input impedance is used)

• Voltage values change depending upon input

impedance of VOM used.)
