•
b
: Pattern from the side which enables seeing.
  (The other layers' patterns are not indicated.)
• Through hole is omitted.
• Circled numbers refer to waveforms.
• There are few cases that the part printed on diagram
isn’t mounted in this model.
• Chip parts.
(For schematic diagrams)
• All capacitors are in

• 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

Note :
The components identified by mark 
!
 or
dotted line with mark 
!
 are critical for safety.
Replace only with part number specified.
(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the
measurement points and ground when composite video
signal is REC or PB.  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.)
When indicating parts by reference number, pleas
include the board name.
