(Fig. S-1-6) Note: When using a soldering iron, care must be taken to ensure that the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle it gently because it may be damaged if force is

Installation 1.Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. 2.The “” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB wh

To avoid damage of pickup follow next procedures. 1) Short the three short lands of FPC cable with solder before removing the FFC cable (CN201) from it. If y

34、ou disconnect the FFC cable (CN201), the laser diode of pickup will be destroyed. (Fig. D5) 2) Disconnect Connectors (CN301), (CN401) and (CN601). Remove two Screws (S-6A) and (S-6B) and lift the DVD Main CBA Unit. (Fig. D5) 3.CAUTION 3: When reassembling, confirm the FFC cable (CN201) is connected
