Safety Instructions, Warnings and Notes 2. Any other component substitution other than original type may increase risk of fire or electrical shock hazard. Safety regulations require that after a repair, you must return the unit in its original condition.
Pay, in particular, attention to the following points: Unplug the mains cord, and connect a wire between the two pins of the mains plug. Set the mains switch to the ‘on’ position keep the mains cord unplugged! Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom.
Only qualified service personnel may remove the cover, or ba5938dm to service this device due to possible eye injury. Use of controls or adjustments or performance datsheet procedure other than those specified herein, may result in hazardous radiation exposure. Avoid direct exposure to beam. Careless handling during repair can reduce life drastically.
Make sure that, during repair, you are at the same potential as the mass of datasheeh set by a wristband with resistance. Datzsheet components and tools at this same potential. Available ESD protection equipment: Be careful during measurements in the live voltage section.
The primary side of the power supply pos. Service personnel must take precautions to prevent touching this area or components in this area. A ‘lightning stroke’ and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply. Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury.
Repair handling should take place as much as possible with a disc loaded inside the player. Text below is placed inside the unit, on the laser cover shield: Firmware OPU flex Flip the module degrees, so you can access the PWB.
Disconnect the four flex foils from the PWB connectors,and at the component side. For the flex foil on connectoryou first must remove the cable clamp . 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 pencil or small screwdriver.
Disconnect the remaining cables tray- and fan-motor cable at the solder side of the PWB 4. Remove the four screws Torx 8 that hold the PWB . Now you can remove the board.
Figures below can deviate slightly from the actual situation, due to the different set executions. Do not place the unit with its PWB on a hard surface e. Always place something soft a towel or foam cushion under it. Never touch the lens of the laser.
Take sufficient ESD measures during dis assembly. Never try to align the DVD-Module! Only the factory can do this properly. Service engineers are only allowed to exchange the sledge motor assy. Slide the ‘tray pin’ in the direction of the arrow , in order to release the disc tray. Flip the module degrees and pull out the tray . Now you can access the DVD-Module. Remove the four screws  with a Torx 6 screwdriver, and lift the DVD-M upwards  at the side of the disc-motor.
It hinges in the bracket at the side of the tilt-motor. Loader fan, clamp, and tray assy. PWB or ‘mono board’. Disconnect the 2-wire fan cable from the PWB. Remove the fan assy, by releasing the four side clamps  while moving it upwards. Remove the clamp assy, by releasing the two side clamps  while moving it upwards.
Place the DVD-Module, with the laser facing downwards, on a soft surface. Remove the three screws  that hold the sledge-motor assy, and lift the assy upwards. You can replace it now. If necessary, it is now also possible to replace the sledgerack  that is hinged in the sledge assy.
Mesh the teeth of the sledge motor and sledge rack properly, during mounting of the sledgemotor assy. Point the laser up towards the traywhen you mount the DVD-M in the bracket. Nuclei Error Codes 5. Most tests are done by software commands. Together with the software command you will find a Ref. This is the number of the diagnostic nucleus used for this test. You can find information that is more detailed in the chapter ‘Diagnostic Nuclei’.
Most measurements are digital measurements. The signal levels specification in this document are defined as follows: Menu interface only for Digiboard Empress.
Table Table of derived supply voltages. This part describes the command and menu interface. To reduce this time, the recorder has been equipped with Diagnostic and Service software DS. This is also valid for the Basic Engine. Table Table of supply input voltages. Tolerance Unit -5 I Neg. 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.
This number is the input of the command mode.
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 datashfet power supply to the mono board via connectorand the PC interface cable to the Service Interface connector of the ‘test recorder’.
This code contains six numerals, which means: This means that the player hangs. HyperTerminal installed and must have a free COM port e. Activate the terminal emulation program and check that the port settings for the free COM port are: This special cable will also connect the test pin, which is available on the connector, to ground i.
DVD-Video Recorder DVD+RW Basic Engine – Page de test
Code number of PC interface cable: This is only done when the result of the self-test contains no errors. The following text will appear on the screen of the terminal program for Digiboard Empress: The last line allows the user to choose between the three possible interface forms. The diagnostic software is now ready to receive commands. The commands that can be given are the numbers of the nuclei.
Digital Board Chrysalis always starts with Command Interface. Command Overview We provide an overview dafasheet the nuclei and their numbers. This overview is preliminary and subject to modifications. Please refer to the service manual of the set for the nucleus overview of Digital Board Chrysalis. It allows the radial loop to be calibrated. This disc will be recognized as an empty disc by the application.
