NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKNever look into the laser diode emission from right above whenchecking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK(LCX-4R)The laser diode in the optical pick-up block may suffer electrostaticbreak-down easily. When handling it, perform solderingbridge to the laser-tap on the flexible board. Also perform measuresagainst electrostatic break-down sufficiently before the operation.The flexible board is easily damaged and should be handled withcare.

OPTICAL PICK-UP FLEXIBLE BOARD

SECTION 1SERVICING NOTES

• When repairing this device with the power on, if you remove theMAIN board or open the upper panel assy, this device stops work-ing.In this case, you can work without the device stopping by fasten-ing the hook of the open/close detect switch (S804).

• This set is designed to perform automatic adjustment for eachadjustment and write its value to EEPROM. Therefore, whenEEPROM (IC802) has been replaced in service, be sure to per-form automatic adjustment and write resultant values to the newEEPROM.(Refer to Section 5 Electrical Adjustment. (page 19))

• Replacement of CXD 2671-209GA (IC801) used in this set re-quires a special tool.

z UNLEADED SOLDERBoards 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 withthe 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 beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350°C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful!

• Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

NOTE:• Due to standardization, replacements in the

parts list may be different from the parts speci-fied in the diagrams or the components usedon the set.

• -XX and -X mean standardized parts, so theymay have some difference from the originalone.

• RESISTORSAll resistors are in ohms.METAL: Metal-film resistor.METAL OXIDE: Metal oxide-film resistor.F: nonflammable

• Items marked “*” are not stocked since theyare seldom required for routine service.Some delay should be anticipated when order-ing these items.

• SEMICONDUCTORSIn each case, u: µ, for example:uA. . : µA. . uPA. . : µPA. .uPB. . : µPB. . uPC. . : µPC. .uPD. . : µPD. .

• CAPACITORSuF: µF

• COILSuH: µH

The components identified bymark 0 or dotted line with mark0 are critical for safety.Replace only with part numberspecified.
