TABLE OF CONTENTS NOTES ON CHIP COMPONENT REPLACEMENT - Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged 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-RELATED COMPONET 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.CAUTION Use of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radia- tion exposure.

MEX-DV150UE/DV1500U/DV1505U 3 SECTION 1 SERVICING NOTES The laser diode in the optical pick-up block may suffer electrostat- ic 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 exible board is easily damaged and should be handled with care. NOTE ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc re ective surface by the objective lens in tha optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. UNLEADED SOLDER Boards 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 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 viscous (sticky, less prone to ow) 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.

When this part is damaged, exchange the entire mounted board. NOTE FOR REPLACING THE COMPLETE MAIN BOARD If the complete MAIN board was replaced, be sure to refer to Tech- nical News published separately. NOTE FOR THE 20-PIN CONNECTOR (CN901) Do not use alcohol to clean the 20-pin connector (CN901) connect- ing the front panel with the main body. Do not touch the connector directly with your bare hand. Poor con- tact may be caused.
