6-4. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

• 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 specified.
• All resistors are in ohms.
K =1000 , M =1000k
• Indication of resistance, which does not have one for rating electrical power,
is as follows. Pitch : 5mm
Rating electrical power :
• 1 / W in resistance, 1 / W and 1 / W in chip resistance.

• : nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
• 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
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 R530 and R531 adjustment on Page 19.)
• When replacing the part in below table, be sure to perform the related
adjustment.
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10M 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 symbol display is on the component side.
The components identified by shading and mark
critical for safety. Replace only with part number specified.
The symbol indicate fast operating fuse.
Replace only with fuse of same rating as marked.
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.
