Cautions at Service

1. General Items

1) Be careful not to have your eyes or a part of body touch with laser diode at repair because this product uses laser diode.

2) Do not disassemble Pick-up at repair. If the laser diode is bad, replace the entire Pick-up.

3) Keep away from TV or other electrical units at repair to prevent influence from surrounding units.

4) If you replace the parts during repair, be sure to unplug the power cable before replacement.

5) If you insert a disc into the drive, be sure to load it correctly.

6)Because this unit can't be used by itself, surely mount it on PC (486 DMA support) and check the operations in use of private device driver floppy diskette. Refer to Instruction manual.

7)This unit has many parts with features related to safety and especially, for essential parts, the importance is indicated on circuit diagram and part list. Be certain to use the parts with same specifications at replacing these parts.

- Because the laser diode in optical Pick-up is subject

1)Body earthing(hand) : Be sure to wear a wrist strip

2) Work table earthing : Put the earthed conductive

3)Cautions for clothes : Do not have any clothes

Earthing cautions at handling Pick-up

to get out of order due to the potential difference occurring by electricity load charged in clothes or bodies, observe the following earthing items at handling.

with one side earthed.(Impedance : Below 104). It removes the electricity formed in body.

plate(Impedance : Below 104) such as copper plate on work table.

touch with Pick-up because the electricity formed in clothes is destroyed easily.

Disassembly Method

1. COVER BOTTOM ASSY disassembly

Remove 4 screws 31 on the bottom of COVER BOTTOM ASSY, lift the back up and

disassemble

2. COVER-TOP disassembly

After disassembling 6 hooks of FRONT ASSY 29from COVER TOP 30, pull COVER TOP 30 forward and disassemble it.

3. ASSY DECK+PCB MAIN disassembly

Disassemble FPC PICK-UP

disassemble between deck and PCB main.

COVER BOTTOM ASSY as shown in the figure of the next page.

24 and FPC MOTOR 25 connected between assy deck and PCB main, then
