Section 8 Diagrams

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 ∝ F unless otherwise noted. pF: ∝∝ 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.

[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 is received from the color bar generator (digital multi-meter used: 10 M ohms/

V DC).

.A voltage value is the reference value between the measurement point and the earth, when the NTSC color bar signal and RGB color bar signal are received from the color bar generator (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 : NTSC (3.58 MHz) color bar signal.

. ( ) : PAL color bar signal is received.

.< > : SECAM color bar signal is received.

.<< >> : NTSC (4.43 MHz) color bar signal is received.

. [	] : RGB color bar signal is received.
.	: Measurement disabled.

• Circled numbers indicate the reference waveform.

• : Signal path.

The components identified marked ! are critical for safety.

Replace only with the part number specified.

Les composants identifiés par la marque ! sont critiques pour la sécurité.

Ne les remplacer que par une pièce portant le numéro spécifié.

NOTE:

The circuit indicated as shown on the left contains high voltages of over 600 Vp-p. Take care to avoid electric shock during inspection or repair work.
