SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

2. FRONT PANEL ASSY Proceeding : TOP COVER → DOOR → FRONT PANEL ASSY (1) Remove the screws. View from bottom (2) Cut the clamp bands, disconnect the connector wires and FFC Cable. FFC Cable CN92 cut CN61 (3) Remove the screws. Please refer to "EXPLODED VIEW" for the disassembly method of each PCB included in FRONT PANEL ASSY.
3. CD MECHANISM ASSY Proceeding : TOP COVER → DOOR → FRONT PANEL ASSY CD MECHANISM ASSY → (1) Disconnect the connector wires. CN33 CN32 (2) Remove the screws. ً ً (3) Laser short-circuit in Pick-up of CD MECHANISM, then disconnect the FFC Cable.
DISASSEMBLY OF MECHANIC (Follow the procedure below in reverse order when reassembling.) Caution : The optical pickup can damaged by sassily by static electricity charged on human body. Take necessary anti-static measures when repairing around the optical pickup. 1. Chucking plate (1) Remove 2 top screws, then detach the Chucking plate. (2) Detaching the Chucking pulley and chucking yoke by removing the 3 hooks, when abandoning CD MECHA ass’y.
Note Handling and Replacement of the Laser pick-up 1. Protection of the LD Short a part of the LD circuit by soldering. After connection to a circuit, remove the short solder. 2. Precautions when handling the laser CD mechanism • Handle the laser pick-up so that it is not exposed to dust. • Do not leave the laser pick-up bare. Be sure to cover it. • If dust adheres on lens of the pick-up, blow it off with a blower brush. • Do not shock the laser pick-up. • Do not watch the light of the laser pick-up. 3.

NOTE FOR SCHEMATIC DIAGRAM WARNING: Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacturer. CAUTION: Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.
