[Measuring conditions, voltage and waveform]
.....
A voltage value is the reference value between the measurement
point and the earth, when the NTSC color bar signal, RGB color
bar signal and YUV signal are received from the color bar genera-
tor (digital multi-meter used: 10 M ohms/V DC).
.....
Unit of voltage is V (volt).
.....
: B+line
.....
: B– line
.....
Voltage variations may occur due to normal production tolerances.
.....
No mark : RGB color bar signal.
• Circled numbers indicate the reference waveform.
•
: Signal path.
Les composants identifiés par la marque
!
sont critiques pour la sécurité.
Ne les remplacer que par une pièce portant
le numéro spécifié.
Note:
.....
Parts marked “
*
” differ according to the model/destination. Refer
to the mount table for each function.
.....
The parts marked “ # ” on schematic diagrams are not mounted.
.....
All capacitors are in
µ
F unless otherwise noted. pF:
µµ
F 50WV or
less are not indicated except for electrolytics.
.....
All electrolytics are in 50 V unless otherwise specified.
.....
: fusible resistor
.....
: nonflammable resistor
.....
∆
: internal component
.....
: panel designation and adjustment for repair
.....
Caution when replacing chip parts
New parts must be attached after removal of the chip.
Be careful not to heat the minus side of a tantalum capacitor, be-
cause it is easily damaged by the heat.
