Repair according to the diagnosis method of “5.3 POWER SUPPLY DIAGNOSIS INFORMATION.” About voltage monitoring This product includes user se

17、tting items. Check the settings before repairing. Use the check sheet prepared in item 8.5 to transcribe the settings. Setting contents are stored in the Flash ROM (IC2003) in the MAIN ASSY. For confirming or changing setting contents, refer to “Changing the settings” of the Operationg Instructions.

18、 Checking user setting contents The contactless fader is mounted in the cross fader part of this product. This has several times of durability comparing with conventional types. As assembly of the fader part is required high precision, service parts are provided only as an assembly (Part name is CRO

19、SS FADER ASSY (DXA2257). After replacing the part, make sure to acquire and save the maximum and minimum A/D values of Cross fader setting mode (CFDR SET) in the test mode. If this calibration is not conducted, normal start is not possible. If MAIN ASSY is replaced, make sure to acquire and save the

20、 maximum and minimum A/D values of Cross fader setting mode (CFDR SET) after the replacement. About the replacing CROSS FADER ASSY Display part of this product employs OLED. Exchange at the time of OLED failure, replace using OLED ASSY (DEA1065). Matrix OEL is stick to Holder using double side tape.

21、 If trying to peel in the case of failing to paste, fault will be caused due to the stress. Service part supplies as ASSY who stuck Matrix OEL and Holder. About the replacing OLED ASSY C4638 and C4639 in the MAIN ASSY are locked with bond to prevent solder cracks caused by fall or vibration. When an

22、y of them is replaced for repair, it must be locked with bond after the replacement. Silicon Bond: GYA 1011 About the replacing Capacitor (C4638, C4639) 5DJM-750MK2 5678 5678 A B C D E F Checking LEDs No polarity C4C5 Primary side of SW POWER SUPPLY remains voltage long time and the primary solder s

23、ide can be seen. So if you touch the primary solder side, it is possible to receive an electrical shock. There is the red area below where you tend to receive an electrical shock. Be sure to discharge the voltage of primary side to avoid receiving the electrical shock. When discharging the above poi

24、nt, use the following discarge jig as needed. While the charging voltage is left of both C4 and C5, either of checking LEDs turns on. And if both of LED turns off, you can avoid receiving the electrical shock! DWR1548 (SW POWER SUPPLY) Primary side electrical shock When replacing the Control Panel,

25、replace using Control Panel (Service ASSY) : DEA1077 Control Panel supplies as Service ASSY who stuck Packing and double side tape for Lens because precision is necessary of sticking of them. About the replacing Control Panel Electrical shock area of A-side. Electrical shock area of B-side. Circuit
