SAFETY CHECK-OUT (US Model)

SECTION 1 SERVICE NOTENOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown 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 more than 30 cm away from the objective lens.

After correcting the original service problem, perform the following 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 The AC 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 0.5mA (500 microampers). 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-operated AC 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 indication is 0.75V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

To Exposed Metal Parts on Set

LASER DIODE AND FOCUS SEARCH OPERATION CHECK 1. Close the lid for CD. 2. Press CD ^ button. 3. Confirm the laser diode emission while observing the objecting lens. When there is no emission, Auto Power Control circuit or Optical Pick-up is broken. Objective lens moves up and down once for the focus search. CAUTION DURING WHEN MOUNTING THE PULLEY FOR THE LOADING MOTOR Make the following adjustment when mounting the loading motor (part number : 1-698-999-11) and motor pulley (part number : 2627-174-01) of the CD section.

Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270C 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. 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.SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK !ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

ABOUT THE BD BOARD WAVEFORM CHECKING JIG The special jig (J-2501-124-A) is highly convenient when checking the waveform of the BD board of the MD section. Pin names and items to check are as follows: I+3V : for IOP measurement (check for depleted optical pickup laser) IOP : for IOP measurement (check for depleted optical pickup laser) TEO : TRK error signal (traverse adjustment) VC : Standard level for checking signals RF : RF signal (jitter check)

SECTION 4 TEST MODE4-1. CAUTIONS WHEN USING THE TEST MODE1 Check to make sure the inserted disk is completed stopped before removing since loading related operations will operate regardless of the Test mode operation. The rotation of the inserted disk will not stop even when pressing the MD EJECT button during continuous playback and continuous recording. In this case, the disk will be ejected while still in motion. Always press the CANCEL/NO button and check to see that the disk has stopped turning before pressing the MD EJECT button. 2 In the Test mode, detection of the write-protect tab is executed. For this reason, pressing the REC button in modes where the recording laser is emitted (see 3-1-1) will delete the recorded contents regardless of the tab position. When using a disk in the Test mode which its contents must not be deleted, avoid entering the Continuous Recording mode and Transverse Adjustment mode. 4-1-1. Modes which the record laser is emitted and button operations Continuous Recording mode (CREC MODE) Traverse Adjustment mode (EFBAL ADJUST) Laser Power Adjustment mode (LDPWR ADJUST) Laser Power Check mode (LDPWR CHECK) Traverse (MO) check (EF MO CHECK) Traverse (MO) adjustment (EF MO ADJUST) When pressing the REC button

5-2. CAUTIONS WHEN HANDLING THE OPTICAL PICK-UP (KMS-260A)The laser diode within the optical pick-up is extremely vulnerable to static electricity. When handling, bridge the laser tap of the flexible board on the optical pick-up with solder. When removing the connector, first bridge the laser tap with solder. Furthermore, do not remove the soldered bridge before reconnecting. In addition, take sufficient measures when working to prevent electrostatic damage. Take caution when handling the flexible board since it is easily torn.

Exit the test mode when completed with adjustment. 2) Perform adjustments in the order given. 3) Use the following jig and measuring equipment: Check disk (MD) TDYS-I (Part no : 4-963-646-01) Laser power meter LPM-8001 (Part no : J-2501-046-A) Oscilloscope (perform measurement after calibrating the probe) Digital voltmeter Thermometer BD board waveform checking jig (part no : J-2501-124-A) 5) When looking at multiple signals using oscilloscope, etc., make sure VC and GND are not connected within the oscilloscope. Failure to do so will short circuit VC and GND. 6) Using the special jig enables checking of the waveform without soldering (see page 4 of Service Notes).
