SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-static break-down because of the potential difference generatedby the charged electrostatic load, etc. on clothing and the humanbody.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 electro-static break-down easily. When handling it, perform solderingbridge to the laser-tap on the flexible board. Also perform mea-sures against electrostatic break-down sufficiently before the op-eration. The flexible board is easily damaged and should be handledwith care.
OPTICAL PICK-UP FLEXIBLE BOARD
• In performing the repair with the power supplied to the set,removing the MAIN board causes the set to be disabled.In such a case, fix a convex part of the open/close detect switch(S806 on MAIN board) with a tape in advance.Handle the FLEXIBLE board (overwrite head) with care, as ithas been soldered directly to the MAIN board.In repairing the component side of MAIN board, connect theFLEXIBLE board (overwrite head) and the MAIN board withthe lead wires in advance. (See page 8)
• Replacement of CDX2671-204GA (IC801) used in this setrequires a special tool.
• On the set having the microcomputer version 1.000, someadjusted values were set in the manual mode at the shipment,but these data will be cleared when the NV is reset. Therefore,on the set having the microcomputer version 1.000, change theadjusted values following the Change of Adjusted Valuesimmediately after the NV was reset. (See page 18)
• If the nonvolatile memory was replaced on the set, the modifiedprogram data must be written to the nonvolatile memory. In sucha case, write the modified data that meets the microcomputerversion following the patch data rewriting procedure at thereplacement of nonvolatile memory. (See page 23)
