SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat­ic 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 fl exible 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 refl ective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C. Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to fl ow)
than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

ELECTRICAL CHECKS

FM TUNE LEVEL CHECK
Procedure:
1. Turn on the set.
2. Input the following signal from signal generator to FM antenna input directly.
Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation :75 kHz Modulation : 1 kHz ANT input : 35 dBu (EMF)
Note: Use 75 ohm coaxial cable to connect signal generator and the set.
You cannot use video cable for checking.
Use signal generator whose output impedance is 75 ohm.
3. Set to FM tuner function and tune A, B and C signals.
4. Confi rm “TUNED” is lit on the display for A, B and C sig- nals.
When the selected station signal is received in good condition, “TUNED” is displayed.
Note:
1. CD Block is basically constructed to operate without adjust­ment.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicat­ed.
3. Use an oscilloscope with more than 10 MΩ impedance.
4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specifi ed value with the fol- lowing checks.
5. Check the focus bias check when optical pick-up block is re­placed.
FOCUS BIAS CHECK
Procedure:
1. Connect oscilloscope to TP121 (RFI) and TP124 (VC) on the CD board.
2. Press the [?/1] button to turn the power on.
3. Set disc (YEDS-18) on the disc tray and press the [CD u] button to playback.
4. Confi rm that oscilloscope waveform is as shown in the fi gure below. (eye pattern)
A good eye pattern means that the diamond shape () in the
center of the waveform can be clearly distinguished.
