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 connector shell, 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 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 lowvoltage 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)

• Possibility of display unit defect
Check of AK4524
No problem when around 3MHz of rectangular wave (3.3Vpp) is output from the 13-pin SDTO. (The rectangular wave
changes depending on the audio signal.)
For the analog system, check the inputs (2 and 3 pins) and the outputs (25 through 28 pins). The outputs of these
terminals change depending on the volume adjustments.
Check of AK4114
No problem when around 3MHz of rectangular wave (3.3Vpp) is output for the JL5003[SPDIF]. (The rectangular wave
changes depending on the audio signal.)
Check that 48KHz of rectangular wave (3.3Vpp) is supplied to the 24-pin LRCK. (Supply source: AK4524)
Check that 3.072MHz of rectangular wave (3.3Vpp) is supplied to the 26-pin BICK. (Supply source: AK4524)
Check of Display Signal Out terminals (Black)
The output signal level is about 3.3Vpp when the Display Signal Out terminals are not connected to the display unit.
If the signals, SPDIF+/- and UART_O+/-, are output, no problem for the sending end.
(When the Display Signal Out terminals are connected to the display unit, the signal level is about 350mVpp since the
signal is terminated at display unit.)
For receiving ends (SIRCS input and UART input), the check can only be performed when the Display Signal Out
terminals are connected to the display unit.
Note:
When the insertion of the headphone terminal is detected, the display unit and the woofer
terminal do not output the sound.
In this condition, when the volume operation is performed, the headphone icon is
displayed.
If the condition of small or no sound occurs for only one channel, perform the balance
adjustment beforehand:
Select [AUDIO ADJ.] and [BALANCE] in order from the menu display for each input
source.
• Check two CXA2069Q's
• Check input of NJW1149
