(For schematic diagrams)
•All capacitors are in µF unless otherwise noted. pF : µ
µF. 50Vor lessare notindicated exceptforelectrolytics
and tantalums.
•Chip resistors are 1/10 W unless otherwise noted.
kΩ=1000 Ω, MΩ=1000 kΩ.
•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 C541 L452
22U 10UH
TA A2520
•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.
•Allvariableand adjustableresistors havecharacteristic
curve B, unless otherwise noted.
•Signal name
XEDIT→ EDIT PB/XREC →PB/REC
•2: non flammable resistor
•5: fusible resistor
•C: panel designation
•A: B+ Line
•B: B– Line
•J: IN/OUT direction of (+,–) B LINE.
•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
colorbar chart ofpatternbox. Theyare referencevalues
and reference waveforms.
(VOM of DC 10 MΩinput 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.
When indicating parts by reference number, please
include the board name.
