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 µF unless otherwise noted. pF: µµF 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 RGB color bar signal is 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.

. : Measurement disabled.

.Circled numbers indicate the reference waveform.

.

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.
