¥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
isnÕt mounted in this model.
¥ Chip parts.
(For schematic diagrams)
¥ All capacitors are in mF unless otherwise noted. pF : mmF.
50V or less are not indicated except for electrolytics and
tantalums.
¥ Chip resistors are 1/10W unless otherwise noted.
kW=1000W, MW=1000kW.
¥ 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, Be-
cause it is damaged by the heat.
¥ Some chip part will be indicated as follows.
Example C541 L452
22U 10UH

¥ 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 H 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

¥2: non flammable resistor
¥1: fusible resistor
¥C: panel designation

¥J: IN/OUT direction of (+,Ð) B LINE. *
¥C: adjustment for repair. *
¥ Circled numbers refer to waveforms. *
*Indicated by the color red.
(Measuring conditions voltage and waveform)¥ Voltages and waveforms are measured between the measure-
ment points and ground when camera shoots color bar chart of
pattern box.  They are reference values   and reference wave-
forms. *
(VOM of DC 10 MW input impedance is used.).
¥ Voltage values change depending upon input impedance of VOM
used.)
1. Connection
2. Adjust the distance so that the output waveform of Fig. a and
the Fig. b can be obtain.
3. ¥ The LINE REC waveform shows the waveform when the color
for signal (video signal) is input from a color bar pattern.
¥ The LINE OUT waveform shows the waveform when the
signals are connected to the S-VIDEO and VIDEO/AUDIO
jacks but not to other jacks.
