: nonflammable resistor.

•

 : fusible resistor.

• 

 : internal component.

•

 : panel designation and adjustment for repair.

• All variable and adjustable resistors have characteristic curve B, unless other-

wise 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 adjust-

ments indicated. If results do not meet the specified value, change the compo-
nent identified by 

 and repeat the adjustment until the specified value is

achieved.

(Refer to RV8002 adjustment on Page 56.)

• Readings are taken with a PAL color-bar signal input.
• Readings are taken with a 10M

Ω

 digital multimeter.

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.

• 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.

•  

 : B+ bus.

•  

 : B– bus.
