SCHEMATIC DIAGRAMS
Note:
* All capacitors are in uË unless otherwise noted. pF * F 50WV or less are not
indicated except for electrolytics and tantalums.
° All electrolytics are in 50V unless otherwise specified.
* All resistors are in ohms.
kQ=10002, MQ=1000kQ
* Indication of resistance, which does not have one for rating electrical power, is
as follows.
Pitch : 5mm
Rating electrical power : '/4W
+ Va W in resistance, V, W and t/sW in chip resistance.
+ РАЗ : nonflammable resistor.
NA : fusible resistor.
* А : Internal component.
* СС]: panel designation and adjustment for repair.
* All vanable and adjustable resistors have characteristic curve B, unless other-
wise noted.
* The components identified by Ё@ in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regarding
X-ray radiation.
Should replacement be required, replace only with the value originally used
• When replacing components identified by [4 , make the necessary adjust-
ments indicated. If results do not meet the specified value, change the compo-
nent identified by М, and repeat the adjustment until the specified value 18
achieved.
(Refer to R530 and R531 adjustment on Page 14 - 15.)
• When replacing the part in below table, be sure to perform the related adjust-
ment.

Note:
The symbol JIEZE- display ıs оп the component side.
The components identified by shading and mark А are
critical for safety. Replace only with part number specified.
The symbol AE indicate fast operating fuse.
Replace only with fuse of same rating as maked.
Note:
Les composants identifiés per un tramé et une marque А
sont critiques pour la sécurité. Ne les remplacer que par une
piéce portant le numéro spécifié.
Le symbole "ЕЕЕ- indique une fusible a action rapide. бой
etre remplacee par une fusible de meme yaleur, comme
maque.
