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.

• : 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 R536,R545 and C517 adjustment on Page 38 – 39.)

•When replacing the part in below table, be sure to perform the related adjustment.

• Readings are taken with a NTSC color-bar signal input.
• Readings are taken with a 10MΩ	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.
• Circled numbers are waveform references.
