4-2. SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(For schematic diagrams)
All capacitors are in F unless otherwise noted. pF :
Link
F. 50 V or less are not indicated except for electrolytics
and tantalums.
Chip resistors are 1/10 W unless otherwise noted.
k =1000 , M =1000 k .
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.
Example
Kinds of capacitor
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
Refer to the mount table for each function.
All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.

2: non flammable resistor
5: fusible resistor
C: panel designation

C: adjustment for repair.
A: not use circuit
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 input impedance is used)
Voltage values change depending upon input
impedance of VOM used.)
The components identified by mark 0 or
Note :
dotted line with mark 0 are critical for safety.
Replace only with part number specified.
