WHEN SERVICING, DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION, BE

11、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 increase eye hazard. Unleaded solder Boards requiring use of unleaded solder are printed with the lead- free mark (LF)

12、 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 40C higher than ordinary solder.

13、 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 350C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so b

14、e 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. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary s

REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY

16、 SONY. 1.Check the area of your 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, partic

17、ularly transistors, that were 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 t

18、o see it is at the values specified. 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

19、or unsoldering. SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

44、an unnecessary program. Video Program System (VPS) The Video Program System (VPS) ensures that the TV program that you have programmed for timer recording will be recorded exactly from their beginning to end, even if the actual broadcasting time differs from the scheduled time due to delayed start,

45、or if the program is extended beyond its scheduled time. Also, if a program is interrupted, for example, if a news flash is inserted, the recording will also be interrupted automatically and resumed when the program continues. The VPS signal is broadcast by the TV station and this controls the timer

46、 in the unit. VPS should be set ON for all timer recordings from TV stations broadcasting these signals. It should be set OFF for all timer recordings from TV stations that are not broadcasting these signals. * The similar system PDC, which is used in the time being in the Netherlands, can also be u

47、sed with this unit. Notes Do not set PDC/VPS to ON for a non-PDC/VPS channel. When the PDC/VPS signal drops out because the broadcast signal is weak, or when a broadcasting station does not transmit a regular PDC/VPS signal, the timer recording will be performed in the normal mode (without PDC/VPS)

48、even if it was programmed for PDC/VPS. 36 Operation with Tape (Continued) Timer Recording Using On Screen Display You may set up to 7 timer record events within one month of the current date. Note Before setting the timer make sure that you have set the units clock correctly and you know which stati
