Note :
© All capacitors are in uF unless otherwise noted. pF: wuF SOV
or less are not indicated except for electrolytics and tantalums.
e All electrolytics are in 50V unless otherwise specified.
e All resistors are in ohms.
kQ= 1000 2, MQ = 1000k2
@ Indication of resistance, which dose not have one for rating
electrical power, is as follows.
Pitch : 5mm
Rating electrical power: 4%W
© 4B}: nonflammable resistor.
e fw : fusible resistor.
e A :internal component.
° Cc] : panel designation and adjustment for repair.
e All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
@ The components identified by b4 in this basic schematic diagram
have been carefully factory-selected for each set in order to
satisfy regulations regarding X-ray radiation.
© When replacing components identified by [d, make the necessary
adjustments indicated. if results do not meet the specified value,
change the component identified by bd and repeat the adjustment
until the specified value is achieved.
(Refer to R511 and R524 adjustment on Page 20, 25.)
e When replacing the part in below table, be sure to perform the
related adjustment.

As to the voltage volue shown by the semiconductors on the
Schematic Diagram, see the another list.
e Readings are taken wita a color-bar signal input.
e Readings are taken with a 10M 2 digital multimeter.
e 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 -&=# display is on the component side
The components identified by shading and mark A\
are critical for safety. Replace only with part
number specified.
The symbol 4&4 indicate fast operating fuse.
Replace only with fuse of same rating as maked
: Les composants identifiés per un tramé et une
marque /\ sont critiques pour la sécurité. Ne les
remplacer que par une piéce portant le numéro
spécifié.
Le symbole 4+ indique une fusible a action
rapide. Doit etre remplacee par une fusible de
meme yaleur, comme maque.
