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.

Circled numbers refer to waveforms.

•

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

 input impedance is used)

•

Voltage values change depending upon input
impedance of VOM used.)
