3、still attached by screws, as shown in the figure below. Disassembly Procedure (see DIsAssEMBLY for details on the disassembly procedure) 1. Remove all of the screws from the MAIN PWB, SMPS PWB, CD Mecha, CD Foot, NET PWB, USB PWB and chassis (CD Mecha and CD Foot are for the M-CR610 only). 2. Remove

4、 the SMPS PWB, CD Mecha and CD Foot (CD Mecha and CD Foot are for the M-CR610 only). 3. Remove the wire and FFC connected to the FRONT PWB. 4. Remove the molded parts from the back panel. 5. Raise the MAIN board, slide the entire back panel to the rear, and remove everything from the back panel to P

5、WB as a set. 11 Removing the AMP PWB from the MAIN PWB Pay close attention to the following two points when removing/attaching the AMP PWB to the MAIN PWB during servicing. 1. Wait for approximately 5 minutes after turning the power off before removing the wire connector that connects the SMPS PWB a

6、nd AMP PWB. When connected to the SMPS PWB wire connector, a surge current may occur due to the charge stored in the AMP PWB causing damage to the D-AMP IC41 and IC42 (IC41 only for the M-CR510). 2. When attaching the AMP PWB to the MAIN PWB connector, insert the connector pins into the AMP PWB befo

7、rehand, and securely connect while checking that the position is correct. If the MAIN PWB and AMP PWB terminals are connected incorrectly (if the connection pins are misaligned), the PWM Processor IC56, D-AMP IC41 and IC42 (IC41 only for the M-CR510) may be damaged by the charge stored in the conden

8、ser. 12 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 n

9、ot 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. Cautions on assembling and adjustment Be sure that to the bench, jig, head of soldering iron

10、(with ceramic) and measuring instruments are well grounded. Workers who handle the laser pick-up must be grounded. The finished mechanism (prior to anchoring in the set) should be protected against static electricity and dust. The mechanism must be stored that damaging outside forces are not receive

11、d. When carrying the finished mechanism, hold it by the chassis body For proper operation, storage and operating environment should not contain corrosive gases. For example H2S, SO2, NO2, CI2 etc. In addition storage environment should not have materials that emit corrosive gases especially from sil

12、icic, cyanic, formalin and phenol group. I the mechanism or the set, existence of corrosive gases may cause no rotation in motor. 4. Determining whether the laser pick-up is defective Check the Iop(Laser drive current). Check lop in SPECIAL MODE. (Refer to 21 page.) If the present Iop (current) valu

13、e becomes more than 50mA, replace the Traverse unit with a new one. No mechanical adjustment is necessary after the replacement.
