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 the 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. 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 viscou-s (sticky, less prone to flow) 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.

D-EJ011 SECTION 1 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 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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S811. (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. With a disc not set, turn on the S811 with a screwdriver having a thin tip as shown in Fig.1. 3. Press the u button. 4. Observing the objective lens, check that the laser diode emits light. When the laser diode does not emit light, automatic power control circuit or optical pick-up is faulty. In this operation, the objective lens will move up and down 2 times along with inward motion for the focus search.

The CD section adjustments are done automatically in this set. Adjusting Procedure: 1. Perform check in the order given. 2. Use YEDS-18 disc (Part No: 3-702-101-01) unless otherwise indicated. 3. Power supply voltage requirement :DC4.5 V in DC IN jack. (J401) VOLUME button : Minimum HOLD switch :OFF Focus bias Check Condition: · Hold the set in horizontal state. Connection:
oscilloscope (AC range) TP604 (EQOUT)

Procedure: 1. Make a solder bridge to short SL801 (OPEN) on the MAIN board side B. 2. Connect the oscilloscope to the test point TP604 (EQOUT) and TP406 (M-GND) on the MAIN board side B. 3. Set a disc. (YEDS-18) 4. Press the u button. 5. Check the oscilloscope waveform is as shown below. A good eye pattern means that the diamond shape ( ) in the center of the waveform can be clearly distinguished. RF Signal reference Waveform (Eye Pattern)
