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. P oint 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 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)

4. Perform the adjustment in 10 seconds after connecting
the cord.
• Procedure for adjustment
1. Slide the DIP switch (S3201) No. 7 of P board to on
position with no silkscreen mark r.
2. Confirm the lighting of SONY LOGO LED.
3. Adjust the VS voltage to the following voltage value.
VS voltage of proper value for each model.
Ex.) VS proper value=185V thru 185.6V at 185V.
(Check the proper value with a seal on upper left of
panel unit. Refer to right Fig.)
4. Adjust the VD voltage to the following voltage value.
VD voltage ±0.3V of proper value for each model.
Ex.) VD proper value=64.7V thru 65.3V at 65.0V.
(Check the proper value with a seal on upper left of
panel unit. Refer to right Fig.)
5. Check a Fan rotation.
6. Slide the DIP Switch (S3201) No. 7 of P board to the off
position with the silkscreen mark r.
7. Slide the DIP Switch (S3201) No. 8 of P board to the off
position with the silkscreen mark r.
8. Disconnect an AC cord of DISPLAY UNIT.
9. Reconnect the AC cord in one second.
10. Assure that “POWER ON/STANDBY” LEDs is
flashing amber.

6. After adjusting the values, at the values of the “SCNR”
or “SCNB” exceeding 128 (initialize value).
1) Reset a lager value of the “SCNR” or “SCNB” at 128.
2) Set the White Balances with the last of items and
“SCNG” to the X/Y values above.
7. After the above step, when these item are nonqualified
following conditions, set the largest one at 128 and
readjust the White Balance with the last two item.
1) No one of “SCNR”, “SCNB” and “SCNG” exceeding
128.
2) Confirm the item value 128 at least one item.
8. As a result above, input the sequential number of value

TO A1/12, A2/12_1
• Divided circuit diagram
Schematic diagrams of A, MS, P, TU and U 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 A1/12, A2/12_1 ] means the line is connected to
Ref. No. 1 of A (1/12) and A (2/12) schematic diagrams.
Ref. No.

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.
•: B + bus.
•: B – bus.
•: Signal path.
