SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ! OR DOTTED

4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recommend their replacement.
5. Check the B+ voltage to see it is at the values specified.

(In addition to this, the necessary mote is printed
in each block.)
For printed wiring board:
• X : indicates a lead wire mounted on the component
• x : indicates a lead wire mounted on the printed side.
• ® : Through hole.
• p : Parts mounted on the conductor side.
• b : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from

For schematic Diagram:
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
• All resistors are in ohms, 1/
less otherwise specified.
kΩ : 1000Ω, MW : 1000kΩ.
• All capacitors are in µF unless otherwise noted. pF : µµF
50V or less are not indicated except for electrolytics and
tantalums.
• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• ¢ : internal component.
• C : adjustment for repair.
• U : B+ Line.
• V : B– Line.
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Readings are taken with a color-bar signal input.
• Readings are taken with a digital multimeter (DC 10MW).
• Voltage variations may be noted due to normal production
tolerances.
