LEAKAGE TESTThe 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 2 V AC range are suitable. (SeeFig. A)

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.

S1820
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.
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 higherthan 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.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECKDuring normal operation of the equipment, emission of the laserdiode is prohibited unless the upper lid is closed while turning ONthe S1820. (push switch type)The following checking method for the laser diode is operable.• Method
Emission of the laser diode is visually checked.1. Open the upper lid.2. Push the S1820 as shown in Fig.1.
Note: Do not push the detection lever strongly, or it may be bent or damaged.3. Press the u button.4. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automaticpower control circuit or the optical pick-up.In this operation, the object lens will move up and down 2times along with inward motion for the focus search.

CD SECTION
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 MW impedance.4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.5. Check the focus bias check when optical pick-up block is replaced.
FOCUS BIAS CHECK
Procedure :1. Connect oscilloscope to TP (RFACI) and TP (VC) on the CD
board.2. Press the I/1 button to turn the power ON.3. Set disc (YEDS-18) on the tray and press the CD u button
to playback.4. Confirm that oscilloscope waveform is as shown in the figure
below. (eye pattern)A good eye pattern means that the diamond shape (◊) in thecenter of the waveform can be clearly distinguished.
