• 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
safety

• 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

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.

• Circled numbers are waveform references.
• 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.

The symbol display is on the component side.
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 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.
