Note:
All capacitors are in uF unless otherwise noted. pF: uF SOWV or less
are not indicated except for electrolytics and tantalums.
All resistors are in ohms.

'The components identified by Ba in this basic schematic diagram have been
carefully factory-selectad for each satin order to satisfy regulations regarding
X-ray radiation,
'Should replacement be required, replace only with the value originally used.
When replacing components identified by [@, make the necessary
adjustments indicated. If results do not meet the specified value, change
the component identified by 64 and repeat the adjustment
untill he specified
value is achieved.
(Refer to R514, A561 and C514 adjustment on Page 49 to 51 )
When replacing the part in below table, be sure to perform the related
'adjustment.

* As to the voltage value shown by the semiconductors on the Schematic
Diagram, see the another list.
Readings are taken with a color-bar signal input.
Readings are taken with a 10MQ digital multimeter.
Voltages are de with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
All voltages are in V

Note: The symbol -#&H display is on the component side.
The components identified by shading and mark /\
are critical for safety.
Replace only with part
number specified.
The symbol ++
indicate fast operating fuse.
Replace only with fuse of same rating as marked.
Note: Les composants identifiés per un tramé et une
marque A\ sont critiques pour la sécurité. Ne les
remplacer que par une piéce portant le numéro
spécifié.
Le symbole
