SERVICING NOTES
Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing• Keep the temperature of soldering iron around 270˚C
during 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.
SAFETY CHECK-OUTAfter correcting the original service problem, perform the followingsafety checks 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 asdescribed below.
LEAKAGEThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn 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 RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

This appliance is classified as a CLASS 1 LASER product. TheCLASS 1 LASER PRODUCT MARKING is located on the rearexterior.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.
Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveforms is output three times.
UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free 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 MARKUnleaded 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 beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 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 viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

4. Check the oscilloscope waveform (S-curve) is symmetricalbetween A and B. And confirm peak to peak level within 2 ± 1Vp-p.
S-curve waveform
• Try to measure several times to make sure than the ratio of A : Bor B : A is more than 10 : 7.
• T ake sweep time as long as possible and light up thebrightness to obtain best waveform.

6. Press the CD u button. (The tracking servo and sleddingservo are turned ON)Rotate RV101 on BD board and adjust the C (DC voltage) is almost equal to the A (DC voltage) in step 4.
7. To exit from this mode, turn the power off.Notes: Always move the optical pick-up to most inside track when
exiting from this mode. Otherwise, a disc will not be unloaded. Do not run the sled motor excessively, otherwise the gear can
be chipped.
E-F Balance AdjustmentConnection:
Procedure:1. Connect an oscilloscpe to test point TP (TEO) and TP (VC) on
the BD board.2. AC is put in pushing CD u button to enter the CD test
mode.3. Put the disc (YEDS-18) in to playback the number five track.4. Press the CD button. If it plays, press the CD u
(CD) button. (The tracking servo and the
button again. (The tracking servo and the sledding servo areturned OFF)
5. Check the level B of the oscilliscope’s waveform and the A(DC voltage) of the center of the Traverse waveform.Confirm the following :A/B x 100 = less than 10%
