Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized”knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
TheAC 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-operatedAC 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 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are suit-
able. (See Fig. A)

HCD-XG60/XG500
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis-
sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.

[CD Delivery Mode]
• This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.
Procedure:
1. Press the ?/1button to turn the power ON.
2. Press the [LOOP] and ?/1buttons simultaneously.
3. A message “LOCK” is displayed on the fluorescent indicator
tube, and the CD delivery mode is set.
[LED and Fluorescent IndicatorTube All Lit, Key Check
Mode]
Procedure:
1. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],
and [DISC 2] simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
Press the [DISC 2] button, and the key check mode is acti-
vated.
3. In the key check mode, the fluorescent indicator tube displays
“K 0 J0 V0”. Each time a button is pressed, “K” value in-
creases. However, once a button is pressed, it is no longer taken
into account.
“J” value increases like 1, 2, 3 ... if turn the JOG dial clock-
wise, or it decreases like 0, 9, 8 ... if turn the JOG dial counter-
clockwise.
“V” value increases like 1, 2, 3 ... if turn the [VOLUME] dial
clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial
counterclockwise.
4. To release from this mode, press three buttons in the same
manner as step 1, or disconnect the power cord.
c
[MC Cold Reset]
• The cold reset clears all data including preset data stored in the
RAM to initial conditions. Execute this mode when returning
the set to the customer.
Procedure:
1. Turn the power ON or set to the DEMO mode.
2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT], and
?/1simultaneously.
3. The set is reset, and displays “COLD RESET”, then becomes
DEMO mode.
[MC Hot Reset]
• This mode resets the set with the preset data kept stored in the
memory. The hot reset mode functions same as if the power
cord is plugged in and out.
Procedure:
1. Turn the power ON or set to the DEMO mode.
2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],
and [DISC 1] simultaneously.
3. The set is reset, and becomes standby state.
[Change-over the AMTuning Interval]
(EXCEPT AEP, UK, and Saudi Arabia models)
• The AM tuning interval can be changed over 9 kHz or 10 kHz.
Procedure:

Note:
1. CD Block is basically designed to operate without adjustment. There-
fore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10 MΩimpedance.
4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-Curve Check
Procedure:
1. Connect oscilloscope to TP (FE) and TP (VC).
2. Connect between TP (FE1) and TP (VC) by lead wire.
3. Connect between TP (AGCCON) and TP (GND) by lead wire.
4. Turn the power ON.
5. Load a disc (YEDS-18) and actuate the focus search. (In con-
sequence of open and close the disc tray, actuate the focus
search)
6. Cofirm that the oscilloscope waveform (S-curve) is symmetri-
cal between A and B. And confirm peak to peak level within
4 ±1 Vp-p.
S-curve waveform
7. After check, remove the lead wire connected in step 2 and 3.
Note: • Try to measure several times to make sure than the ratio ofA : B
or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightness
to obtain best waveform.
RF Level Check
Procedure:
1. Connect oscilloscope to TP (RF) and TP (VC).
2. Connect between TP (AGCCON) and TP (GND) by lead wire.
3. Turn the power ON.
4. Load a disc (YEDS-18) and press the HXbutton to play.
5. Confirm that the oscilloscope waveform is clear and check RF
signal level is correct or not.
6. After check, remove the lead wire connected in step 2.
Note: Clear RF signal waveform means that the shape “ ” can be clearly
distinguished at the center of the waveform.
