10、lexible 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

11、replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. SAFETY-RELATED COMPONENT

12、 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. MZ-E510 On power source

13、s Use house current, LR6 (size AA) battery, or car battery. For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction. Connect the AC power adaptor to an easily accessible AC outlet. Should you no

14、tice an abnormality in the AC power adaptor, disconnect it from the AC outlet immidiately. The recorder is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the recorder itself has been turned off. If you are not going to use this recorder for a

15、 long time, be sure to disconnect the power supply (AC power adaptor, dry battery, or car battery cord). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord. Polarity of the plug * Replacement of IC501, IC601 used in this set requires a special too

16、l. The voltage and waveform of CSP (chip size package) can- not be measured, because its lead layout is different from that of conventional IC. Lead layouts Unleaded solder Boards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead. (Cauti

17、on: 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 40C higher than ordinary solder. Ordinary soldering irons can be used but the i

18、ron 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 350C. 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

19、more viscous (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. surface Lead layout of conventional IC C

23、ON 1 SERVICING NOTE NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay att

24、ention 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 Never look into the laser diode emission from right above when checking

25、 it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (ABX-1E) The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perf

While pressing thex key on the set, press the keys on the remote commander with the following order: tt.t.tt .t t.tt Note: If electrical adjustment (

36、CD and MO overall adjustment) has not been finished completely, “ERROR” is displayed on LCDs of the set and the remote commander. SECTION 4 TEST MODE Outline This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall

37、adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be auto- matically adjusted. Operation in the test mode is performed

38、with the set. A key having no particular description in the text, indicates a set key. Setting Method of Test Mode There are two different methods to set the test mode: 1 Short SL601 (TEST) on the MAIN board with a solder bridge and turn on the power.
