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 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 OPERATION CHECK Carry out the "S curve check" in "CD section adjustment" and check that the S curve waveforms is output three times. 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.
This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. The following caution label is located inside the unit.
SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 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.

MCE-SV7 SECTION 1 SERVICING NOTES
This set is a component of the MHC-SV7AV. The MHC-SV7AV system configuration is as shown below, and therefore it does not operate normally unless all four components are connected. In performing the repair, connect all components with the system cables. Note: The precaution to the users is described on the label stuck on the back panel (Video CD player) and in the troubleshooting section in the Operation Manual. System Configuration:
CD-TEXT TEST DISC
This unit is able to display the test data (character information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display. To check, perform the following procedure. Checking Method: 1. Press the I/1 button to turn the power on, set the disc to the disc table with the "test disc" label facing up, and chuck the disc. 2. Press the [CD] button to set CD function, and press the N button to playback the disc. 3. The following will be displayed on the liquid crystal display. Display : 1KHZ/0DB/L R 4. Pressing the [-- .] or [> +] button, select the track. The text data of each track will be displayed. For details of the displayed contents for each track, refer to "Table 1 : CD-TEXT TEST DISC TEXT Data Contents". Restrictions in CD-TEXT Display In this unit, some special characters will not be displayed properly. These will be displayed as a space or a character resembling it.

NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS (In addition to this, the necessary note is printed in each block)
Note on Schematic Diagram: · All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. · All resistors are in and 1/4 W or less unless otherwise specified. f · : internal component. · C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. · A : B+ Line. · H : adjustment for repair. · Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. · Circled numbers refer to waveforms. · Signal path. J : CD PLAY (ANALOG) c : CD PLAY (DIGITAL) g : VIDEO
· Circuit Boards Location
Note on Printed Wiring Boards: · X : parts extracted from the component side. · Y : parts extracted from the conductor side. f : internal component. · · : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A)
