6、 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. 1.Check the area of you

7、r repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2.Check the interboard wiring to ensure that no wires are pinched or contact high-wattage resistors. 3.Look for unauthorized replacement parts, particularly transistors, that were

8、installed during a previous repair. Point them out to the customer and recommend their replacement. 4.Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5.Check the B+ voltage to see it is at the values spec

9、ified. 6.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. SAFETY CHECK-O

10、UT After correcting the original service problem, perform the following safety checks before releasing the set to the customer. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. WARNING! WHEN SERVICING, D

IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION, BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 25 cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK. CAUTION: The use of optical instrument with this product will inc

12、rease eye hazard. 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 sold

13、er has the following characteristics. Unleaded solder melts at a temperature about 40C 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 a

14、bout 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 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. Usa

15、ble with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
