• 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.

• Signal name

• 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.)

• The CD-540 board mounted as a repair part is not equipped

with a CCD imager.
When replacing this board, remove the CCD imager from
the old one and mount it onto the new one.

• If the CCD imager has been replaced, carry out all the

adjustments for the camera section.

• As the CCD imager may be damaged by static electricity

from its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.

2. Adjust the distance so that the output waveform of

Fig. a and the Fig. b can be obtain.

When indicating parts by reference number, please
include the board name.
