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. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC Leakage.
Check leakage as described right.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part
having a return to chassis, must not exceed 0.5 mA (500
microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT -540A. Follow the manuf acturers’ instructions to use these
instruments.
2. A battery-operated A C milliammeter . The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive V OMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range
are suitable. (See Fig. A)

Note:
• All capacitors are in µF unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.
• Indication of resistance, which does not have one for rating electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
• All resistors are in ohms.
• : 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-ground.
• : earth-chassis.
• When replacing the part in below table, be sure to perform the related adjustment.
• All voltages are in V.
• Readings are taken with a 10 M digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production tolerances.
•
• Circled numbers are waveform references.
: Can not be measured.
*
• : B + bus.
• : B – bus.
Note: The components identified by shading and
mark ! are critical for safety. Replace only
with part number specified.
Note: Les composants identifiés par un tramé et
une marque ! sont critiques pour la
sécurité. Ne les remplacer que par une pièce
portant le numéro spécifié.
• Divided circuit diagram
Schematic diagrams of A and B2 boards are divided into serveral pieces.
Information to where the line is to be connected is printed at the end of
wach line.
For example, [ TO A1/5, A2/5 ] means the line is connected to
Ref. No. 1 of A (1/5) and A (2/5) schematic diagrams.
TO A1/5, A2/5
