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 AC 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 low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have a 2 V AC range
are suitable. (See Fig. A)
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 connector shell, metal trim, “metallized” knobs, screws, and
all other exposed metal parts for AC Leakage. Check leakage as de-
scribed right.

Set the Sub-color value to 8 and adjust the C Out level so that the bright-
ness of (1) and (A) is equal to each other and that of (4) and (D) is equal
to each other. Then adjust the Sub-hue so that the brightness of (2) and
(B) is equal to each other and that of (3) and (C) is equal to each other.
Confirm the C Out level and Sub-hue again. (The C Out level and Sub-
hue require tracking several times.)
5. Input a PAL SMPTE 75% color-bar signal to VIDEO 1.
6. Adjust the PAL sub-color while viewing the screen.
Adjust the Sub-color so that the brightness of (1) and (A) is equal to each
other and that of (4) and (D) is equal to each other.
If the adjustment is omitted, set the Sub-color value to 10.
7. Input a SECAM SMPTE 75% color-bar signal to VIDEO 1.
8. Adjust the SECAM Sub-color while viewing the screen.
Adjust the Sub-color so that the brightness of (1) and (A) is equal to each
other and that of (4) and (D) is equal to each other.
If the adjustment is omitted, set the Sub-color value to 9.
9. Cancel the Blue Only mode.
