Handling Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). - Handling of traverse deck (optical pickup) 1.
Page 8
- Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet.
Page 9
6. Precaution of Laser Diode CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. When the unit is turned on: 1. Do not look directly into the pick up lens. 2. Do not use optical instruments to look at the pick up lens. 3.

8. Operation Checks and Main Component Replacement Procedures...
“ATTENTION SERVICER” Some chassis components may have sharp edges. Be careful when disassembling and servicing. 1. This section describes procedures for checking the operation of the major printed circuit boards and replacing the main components. 2. For reassembly after operation checks or replacement, reverse the respective procedures.
Page 12
8.1. Checking Procedure for each major P.C.B. Step 1 Remove 3 screws each side and 5 screws at rear panel. Step 2 Remove the Top Cabinet Step 3 Push catches each side. Remove 2 screws on top to release CD lid.
Page 13
Step 4 Remove the CD changer base together with the CD changer. Step 5 Release 10 screws at rear panel. - Checking for Main P.C.B, Panel P.C.B. and Transformer P.C.B Step 1 Remove 2 screws each side.
- Checking for Power P.C.B. 8.2. Main Component Replacement Procedures 1. Replacement of the Traverse Deck Step 1 Follow the procedures in ‘Disassembly of the Traverse Unit’ ( Step 1 - Step 4 )
Page 15
Step 3 Desolder the 4 legs of the 2 motors and pull out the Servo P.C.B. Step 4 Widen the 3 bosses with a flat screwdriver and pull out the 3 pins. Then remove the Traverse Deck.
Page 16
Step 5 Remove the flexible cable CN 701. - Removal of the flexible cable. Push the top of the connector in the direction of the arrow 1, and then pull out the flexible cable in the direction of the arrow 2. Note: Insert a short pin into the flexible cable for traverse unit.
Before installing the CD servo P.C.B., move the optical pickup towards the outer edge from the marking (black triangle). [Otherwise, the reset detect switch (S701) mounted on the CD servo P.C.B. may be damaged.] 2. Replacement of the Power Amplifier IC Step 1 Follow the procedures in ‘Checking Procedure for each major P.C.B.’...
Step 3 Remove 2 screws fixed to the Power Amplifier IC. Step 4 Unsolder the terminals of Power Amp IC and replace the respective component. 8.3. Disassembly and assembly of the Traverse Unit Step 1 Push the lever from position A to B. Step 2 Pull the stopper (black) in the direction of arrow 1 and push the lever in the direction of arrow 2.
Page 19
Step 4 Lift up the traverse unit and slide out the unit as shown. - Replacement of Traverse Unit Step 1 Place the traverse unit as shown. Step 2 Press in the lever shaft in the direction of arrow 1 as shown and push the traverse unit into the position in the direction of arrow 2.
