: nonflammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless otherwise
noted.
•
: earth-chassis.
• The components identified by
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
, make the necessary adjustments
indicated. If results do not meet the specified value, change the component
identified by
and repeat the adjustment until the specified value is achieved.
(Refer to VR8001 and VR8002 adjustment on Page 33.)
• Readings are taken with a NTSC 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.
*
: Measurement impossibillity.
Note: The symbol
display is on the component slde.
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 maked.
Note: 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
indique une fusible a action rapide.
Doit etre remplacee par une fusible de meme yaleur,
comme maque.

Divided schematic diagram
Schematic diagrams of A, AD, B, D, G, and U boards are divided into several
pieces. Information to where the line is to be connected is printed
at the end of each.
For example, [ TO A1/5,A2/5_1 ] means the line is connected to
Ref. No. 1 of A(1/5) and A(2/5) schematic diagrams.
TO A1/5,A2/5_1
Ref. No.
