Pay, in particular, attention to the following points:Route the wires/cables correctly, and fix them with the mounted cable clamps.Check the insulation of the mains lead for external damage.Check the electrical DC resistance between the mains plug and the second

11、ary side:1. Unplug the mains cord, and connect a wire between the two pins of the mains plug.2. Set the mains switch to the on position (keep the mains cord unplugged!).3. Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom. 4. Repair or correct unit

12、 when the resistance measurement is less than 1 M. 5. Verify this, before you return the unit to the customer/user (ref. UL-standard no. 1492).6. Switch the unit off, and remove the wire between the two pins of the mains plug.2.1.2 Laser SafetyThis unit employs a laser. Only qualified service person

23、on, due to the different set executions.4.1 GeneralFollow the disassemble instructions in described order.Do not place the unit with its PWB on a hard surface (e.g. table), as it could damage the components on it. Always place something soft (a towel or foam cushion) under it.Never touch the lens of

24、 the laser.Take sufficient ESD measures during (dis)assembly.4.2 DisassemblyFigure 4-1 Basic Engine disassembly (part 1)You can divide the Basic Engine into the following parts:1. Loader (fan, clamp, and tray assy).2. PWB (or mono board).3. DVD-Module (OPU, turntable motor, and sledge-motor assy).4.

25、2.1 Loader1. Disconnect the 2-wire fan cable from the PWB.2. Remove the fan assy, by releasing the four side clamps 1 while moving it upwards.3. Remove the clamp assy, by releasing the two side clamps 2 while moving it upwards.4.2.2 PWB1. Flip the module180 degrees, so you can access the PWB.2. Disc

26、onnect the four flex foils from the PWB connectors (1100, 1300, 1302, and 1303) at the component side. For the flex foil on connector 1100, you first must remove the cable clamp 3. The easiest way to do this is to push down the two fixation pins of the clamp (via the holes in the PWB) by means of a

27、pencil or small screwdriver.3. Disconnect the remaining cables (tray- and fan-motor cable) at the solder side of the PWB4. Remove the four screws (Torx 8) that hold the PWB 4.5. Now you can remove the board.4.2.3 DVD-MCaution: Never try to align the DVD-Module! ! ! Only the factory can do this prope

28、rly. Service engineers are only allowed to exchange the sledge motor assy.Figure 4-2 Basic Engine disassembly (part 2)1. Slide the tray pin in the direction of the arrow 1, in order to release the disc tray.2. Flip the module180 degrees and pull out the tray 2. Now you can access the DVD-Module.3. R

29、emove the four screws 3 with a Torx 6 screwdriver, and lift the DVD-M upwards 4 at the side of the disc-motor. It hinges in the bracket at the side of the tilt-motor.

Service engineers are only allowed to exchange the sledge motor assy.Figure 4-3 Sledge-motor assy1. Place the DVD-Module, with the laser facing downwards, on a soft surface.2. Remove

31、 the three screws 1 that hold the sledge-motor assy, and lift the assy upwards. You can replace it now.3. If necessary, it is now also possible to replace the sledge-rack 2 that is hinged in the sledge assy.4.3 Re-assemblyTo re-assemble the module, do all processes in reverse order. Be sure to:Sledg

32、e-motor assy: Mesh the teeth of the sledge motor and sledge rack properly, during mounting of the sledge-motor assy.DVD-M: Point the laser up (towards the tray), when you mount the DVD-M in the bracket.Complete module: Place all wires/cables in their original positionsCL 26532126_014.eps1911021121Se

Nuclei Error Codes5. Fault Finding5.1 GeneralImpedance of measuring-equipment should be 1 MOhm.For testing t

34、he Basic Engine, connect it to a DVD-recorder of the DVDR1000, 900, or 800 series.Most tests are done by software commands. Together with the software command you will find a Ref.# nbr. This is the number of the diagnostic nucleus used for this test. You can find information that is more detailed in

35、 the chapter Diagnostic Nuclei.Levels: Most measurements are digital measurements. The signal levels specification in this document are defined as follows: low 3.0V LOW 4.5V5.2 Start-up Measurements5.2.1 Power Supply CheckTable 5-1 Table of supply input voltages.Table 5-2 Table of derived supply vol

36、tages.The module operates in power off and power on only. There is no standby mode at module level. In power off, the module does not respond to any communication or signal.Before starting the measurement, connect the power supply to the mono board via connector 1000, and the PC interface cable to t

37、he Service Interface connector of the test recorder.5.2.2 Oscillator CheckTable 5-3 Table of clock signals.On the mono board, there are two external oscillators (OSCOUT and CROUT), which are the reference for all clock signals derived in several ICs. To check whether the program (in the MACE micropr

38、ocessor) is running after power on, you can monitor the PSEN (OEn of Flash ROM) on I223 (see test point overview in chapter 6).You can measure the Servo clocks at I326 (RAdial), I334 (FOcus), and I343 (SLedge).5.3 Diagnostic SoftwareDue to the complexity of a DVD recorder, the time to find a defect

39、in the recorder can become long. To reduce this time, the recorder has been equipped with Diagnostic and Service software (DS). The DS offers functionality to diagnose the DVDR hardware and tests the following:Interconnections between components.Accessibility of components.Functionality of the audio

40、 and video paths.This is also valid for the Basic Engine.One can access this functionality via several interfaces:1. End user/Dealer script interface.2. Player script interface.3. Menu and command interface.This part describes all interfaces from the outside world to the diagnostic software, how to

41、use these interfaces, and how to access them.First some definitions:Diagnostic Nucleus. Part of the Diagnostic Software. Each nucleus contains an atomic and software independent diagnostic test, testing a functional part of the DVD player hardware on component level.Script. Part of the Diagnostic So

42、ftware. Each script contains a sequence of Diagnostic Nuclei to be executed.Service PC. PC used by a service or repair person to communicate with the Diagnostic Software in the DVD player.5.3.1 End User/Dealer Script InterfaceThe End user/Dealer script interface gives a diagnosis on a stand-alone DV

43、D recorder; no other equipment is needed.During this mode, a number of hardware tests (nuclei) are automatically executed to check if the recorder is faulty. The diagnosis is simply a fail or pass message. If the message FAIL appears on the display, there is apparently a failure in the recorder. If

44、the message PASS appears, the nuclei in this mode have been executed successfully. There can be still a failure in the recorder because the nuclei in this mode do not Signal Test point Description Specifi-cationsToler-anceUnit+3V3 I007 Input of supply +3.3 1% V+5 I008 Input of supply +5 1% V+4V6 I01

49、ermine which of the DVD recorders modules are faulty, to read the error log and to perform an endurance loop test. To successfully perform the tests, connect the DVD recorder to a TV set. To be able to check results of certain nuclei, the player script expects some interaction of the user (i.e. to approve a test picture or a test sound). Some nuclei (e.g. nuclei that test functionality of the DVDR module) require that a DVD+RW disc is inserted. Only tests within the scope of the diagnostic
