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 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 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)

K Tro u b le Shooting -1
•Symptom 1:No or irregular sounds from the L/R channel (but not from the Woofer Channel).
(To do) Check the input signals to and output signals from the IC2604.
(Your results) There are IIS input signals to the IC, but no PWM or irregular output signals
from the IC.
(Cause) The IC2604 itself might have been sub-standard, or broken.
•Symptom 2: No or irregular sounds from the Woofer channel (but not from the L/R channel)
(To do) Check the input signals to and output signals from the IC2607.
(Your results) There are IIS input signals to the IC, but no PWM or irregular output signals from
the IC.
(Cause) The IC2607 itself might have been sub-standard, or broken.
•Symptom 3: No sounds from either Lch, Rch, or Wch (Only one of three).
(To do) Check the IC2605 (Lch), IC2606 (Rch) and IC2608 (Wch).
(Your results) There are IIS input signals to one of the each, but no PWM or irregular output
signals from one of the each.
(Cause) One of the IC2605 (Lch), IC2606 (Rch) or IC2608 (Wch) might have been sub-standard,
or broken
KDE-W50A10 (K) 2-8
K Tro u b le Shooting -2
Symptom 4: No sounds from L, R, and Wch at all
(To do) Check the AMP_RST port of the IC2605 (Lch), IC2606 (Rch) and IC2608 (Wch).
(Your results) The AMP_RST port is utputting “L”.
(Cause) Microcontroller port (AMP_RST) error or IC2602 and/or IC 2614 might have been
sub-standard or broken
(To do) Check the M_RST port of the LC89056 (IC2600) and CXD9788R (IC2604, IC2607)
(Your results) The M_RST port is outputting “L”
(Cause) Microcontroller port (M_RST) error or IC2609 might have been sub-standard or
broken
(To do) Check the input and output voltage of the IC6103<3.3V> an d IC6101<12V>
(Your results) There are voltages supplied to the IC6103<3.3V> or IC6101<12V> but no
output voltage from ei ther/both ICs
(Cause) Regulators (IC6103<3.3V> or IC6101<12V>) might have been sub-standard or
broken.
(To do) Check the input signals to or output signals from the CXD9835TN (IC2603)
(Your results) There are input IIS signals to the IC, but no output signals from the IC
(Cause) IC2603 might have been sub-standard or broken
(To do) Check the input signals to or output signals from the LC89056 (IC2600)
(Your results) There are input SPDIF signals to the IC, but no output signals from the IC
(Cause) IC2600 might have been sub-standard or broken.
K Tro u b le Shooting -3
•Symptom 5: Different sounds or irregular sound from L,R, or W ch
(Check) Check the input signals to or output signals from the CXD9835TN (IC2603)
(Result) There are input IIS signals present, but no or irregular output signals from the IC
(Cause) IC2603 might have been sub-standard or broken
•Symptom 6: Interrupted or noisy sounds from the L, R, or/and W ch
(Check) Check the error port (JL 2616) of the LC89056 (IC2600)
(Result) Outputting “H”
(Cause) SPDIF error .
SPDIF transmitter might have been sub-standard or broken
or LC89056 (IC2600) might have been sub-standard or broken
