SAFETY CHECK-OUT

(US Model only)

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.

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 line cord for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

To Exposed Metal
Parts on Set

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 manufacturers' 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” indica-

tion is 0.75V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63T rd are ex-

amples of a passive VOM that is suitable. Nearly all battery

operated digital multimeters that have a 2V A C range are suit-

able. (See Fig. A)

SERVICE NOTE

• Note for Repair

Make sure that the flat cable and flexible board are not cracked or bent at the terminal.
Do not insert the cable insufficiently nor crookedly.

Cut and remove the part of gilt
which comes off at the point.
(Take care that there is some pieces of gilt left inside.)

THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block)

For printed wiring boards:

• b : Pattern from the side which enables seeing.
(The other layers’ pattern are not indicated)

• Circled numbers refer to waveforms.

• Through hole is omitted.

• There are few cases that the part printed on diagram isn’t
mounted in this model.

• Chip parts.

For schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF : µµF
50V or less are not indicated except for electrolytics and
tantalums.

• Chip resistors are 1/
kΩ : 1000Ω, MΩ : 1000kΩ.

• 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.

• Some chip part will be indicated as follows.

capacitor characteristics dimensions (mm)

• Constants of resistors, capasitors, ICs and etc with XX indi­cate that they are not used. In such cases, the unused cir­cuits may be indicated.

• Parts with ★ differ according to the model/destination. Re­fer to the mount table for each function.

• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.

• Signal name

XEDIT → EDIT PB/XREC → PB/REC

• 2 : nonflammable resistor.

• 1 : fusible resistor.

• C : panel designation.

• A : B+ Line.*

• B : B– Line.*

• J : IN/OUT direction of B line (+, –).*

• C : adjustment for repair.*

• Circled numbers refer to waveforms.*

Measuring conditions voltege and waveform:

• Voltages and waveforms are measured between the mea­surement points and graound when color bar signal
input.They are reference v alues and reference wav eforms.*
(VOM of DC 10 M Ω input impedance is used)

• Voltage values change depending upon input impedance
of VOM used.

* Indicated by the color red.

Note:

The components identi­fied by mark ! or dotted
line with mark ! are criti­cal for safety.
Replace only with part
number specified.

When indicating parts by reference
number, please include the board
name.

Note:

Les composants identifiés par
une marque ! sont critiques
pour la sécurité.
Ne les remplacer que par une
piéce portant le numéro
spécifié.
