SCHEMATIC DIAGRAMS INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less
are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise speci
Þ ed.
All resistors are in ohms. K Ω =1000 Ω , M Ω =1000k Ω
Indication of resistance, which does not have one for rating
electrical power, is as follows: Pitch : 5mm

: non ß ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10M
Ω digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
All voltages are in V.

The components identi Þ ed by shading and
!
symbol are critical for safety. Replace
only with part number speci Þ ed.
The symbol indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.
Les composants identi Þ es per un trame et une marque
!
sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero speci Þ e.
Le symbole indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
The components identi Þ ed by
X
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
necessary, replace only with the value originally used.
When replacing components identi Þ ed by
Y
, make the necessary
adjustments as indicated. If the results do not meet the speci Þ ed value,
change the component identi Þ ed by
X
and repeat the adjustment until
the speci Þ ed value is achieved.
(Refer to R564 Adjustment on page 15.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
