1.    Performing HD signal Cross-Conversion but not seeing the
      Down-Converted signal.

     Problem:
     Taking 1080i input and forced the output HD standard to 720p for cross-conversion but the down-
     converted signal is not present at the SDTV outputs and seeing the SDTV content.

     1080i/59.94    HD1 input // ==== Internal Processing ==== // HD output      720p/59.94
                                                        +==== // SD output       Not seeing HD content.

     Solution:
     In order to perform simultaneous cross-conversion and down-conversion, the X75HD unit must
     be fitted with the X75OPT-HDDUOCON software key option.


     How do I find out the presence of HDDUOCON option?

3.    Having a Lip Sync problem.
     3.1   Normal audio processing

           Each audio sample rate converter (SRC) can be configured to automatically track the
           processing delay of one of the video outputs.

           To apply the internal audio tracking feature, follow this path: Audio Setup Global Audio
           Config I/O Delay Config and select one of the four or eight I/O Delay SRC# parameter.

           To synchronize the audio, assign the output video type to the associated audio SRC(s).
           The I/O Delay SRC# parameters are responsible for compensating the internal video
           propagation delay such that the audio channels are delayed in correct amount with respect to
           the chosen video output. Pending on the enabled internal processing options and signal path,
           the processed video’s delay may vary from few microseconds to several frames. Therefore the
           aggregation of video delay is derived at the output as the I/O delay signal to be passed to the
           audio synchronizer to match the audio to video delay automatically.

           The figure below illustrates how the I/O Delay signal is derived in SDI to SDI signal processing
           when some of the processing block(s) are activated. Some of the processing blocks that can
           be applied to the signal would be SD ARC, Noise Reduction, User Fixed Delay.




           Due to the flexibility of the M-Path mode, the default setting for this parameter is None and
           this selection sets the X75 in DELAY only mode. When any one of the I/O Delay SRC#
           parameter is set to track certain output video, the Autotrack LED on the control panel is lit.




                                                                                               Page 4 of 17
3.2   Compressed audio processing

      When passing the compressed audio via the AES input or embedded, a proper system
      configuration must be considered.

      If the X75 is set to run in External Reference lock mode and the reference signal is applied,
      the source signal also must be locked to the same reference including the audio otherwise,
      the X75’s internal Frame Sync will repeat or drop the video frame as the input and output
      clocks drift each other. This will affect the Lip Sync over periods of time and also, if the source
      device driving the X75 has an internal frame sync and it may cause pops or clicks on
      downstream device as it may drop or repeat frames as well.

      If the source can not be locked, then the X75 must run in delay mode. This is done by
      selecting the current video input as the Genlock Lock Source.

      The application example below describes how to set the X75 for the Delay mode operation.

      The X75HD takes 1080i or 720p HD signal with embedded audio that is compressed and
      provides fixed 720p with the embedded at the output.

      It is assumed that the Dolby embedded audio is present in one of the AES channels in group1
      audio space. The X75HD is set up in delay mode locking to HD video input thus the
      synchronization of video and audio is not possible. However, the video ProcAmp function is
      possible allowing the user to adjust video levels, video delay, audio delay and other
      parameters.

      Video Parameters
       • Video Setup HD Input HD Input Std Select = Auto
       • Video Setup Routing Setup All Out Sel = HD1
       • Video Setup Digital Output HD Out Std Select = 720p/59.94

      Reference Parameters
       • Reference Setup Genlock Lock Source = HD

      Audio Parameters
       • Audio Setup Routing Audio In Src Select = HD
       • Audio Setup Global Audio Config I/O Delay Config              I/O Delay SRC1 = HD Out
       • Audio Setup Global Audio Config I/O Delay Config              I/O Delay SRC2 = HD Out

      If the Lip Sync still happens with the compressed audio, the best way would be to decode the
      compressed audio to the baseband using the internal plug-in Dolby decoder module in X75
      and re-encode again.




                                                                                            Page 5 of 17
4.    Not passing the embedded audio without the audio module.
     Without the optional audio submodule, the SD-SDI with embedded audio will pass thru the SD-SDI
     output.

     The HD-SDI signal with the embedded audio will not pass thru the HD-SDI output.

     However, when the video frame sync repeats or drops a frame or if there is a hot-switch, there will be
     a disturbance in the embedded audio data stream. This occurs with any video frame sync that
     passes embedded audio with no embedded audio processing.

     The default factory setting for X75SD with no audio option installed does not pass the audio unless
     the following parameter is set accordingly:
     Video Setup Processing SD TSG & Slide Keyer TSG Insert = None.

     There is an implementation issue with X75 version 1.6.100 and below.
     When the frame is rebooted or the Video Input source is switched, the Keyer TSG Insert parameter
     follows the selected input video source. In order to pass the embedded audio again, this parameter
     must be set to NONE again.

     This issue will be addressed on the subsequent software release.




                                                                                              Page 6 of 17
5.    The Major and Minor Alarms are ON.
     The X75 monitors all video and audio inputs, fans and power supplies and when it detects failure
     condition, it will lit the front panel LEDs and generates the alarms on the control network.

     The factory default is set to monitor all alarms therefore, it is most likely that these LEDs are ON.

     The user can globally disable all the alarms and manually enable only the ones that you wish to
     monitor.

     To globally disable all the alarms, select System Config    Alarm Assert Setup     Enable All Alarms
     parameter and choose the Disable option.

     To configure and activate only the alarms that you wish to monitor, you can do this from the Local
     Control Panel or from the Web Browser.

     5.1    Configuring Alarms from the Web Browser
        •   Open up the Internet Explorer.
        •   Type the IP Address of the X75 frame on the Address link.



        •   From the Main web page, select the Monitoring hyperlink.
        •   Select the Configure Alarms hyperlink
        •   Press the EDIT button corresponding to the alarm that you wish to enable and configure it.

     5.2    Configuring Alarms from the Local Control Panel
        • Press the OPTION button and select the Configure Alarm menu to bring up the list of alarm
         parameters.
        • Select the desired alarm parameter by pressing the ENTER button.
        • Within this parameter configuration menu, configure it appropriately.




                                                                                                 Page 7 of 17
6.    Audio control menu is not showing up.
     There are three possible causes:
      (a) If the appearance of the “Audio Setup” menu is random, the X75 software version is 1.4 and
            requires update to version 1.5 or greater.

8.    Power LED(s) are OFF and no display on Local Control Panel.
     There are three possible causes:
      (a) AC power cord came loose at the back of the unit.
      (b) Internal power supply is defective.
      (c) Internal Flash Memory is corrupted or locked up.

     Solution:
     Case A

        Please ensure the AC power cords are firmly pressed into the unit.

     Case B

        Open up the lid and with the Voltage Meter, validate the presence of +24Vdc on Main DC
        cable(s).

9.   Unlocking Flash Memory
     When user interrupts the firmware update process either by turning Off the unit or initiating a
     break from the PC during the files transfer can trigger the Flash Memory lockup state. When it
     happens, manual unlock procedure is required and please refer to next page for the instructions.

     •      Put both Def. IP and Failsafe dip switches at the back of the X75 unit to the DOWN position
         and re-power the unit.
         (Note: This sets the unit with the default IP of 192.168.100.250 and opens the FTP port for the
         file transfer.)

     •     Connect the network cable and ensure the network connection is valid:
         Ping 192.169.100.250 <ENTER>
         (Note: If the network connection is valid, the REPLY messages should come back.)

     •    Type: TELNET 192.168.100.250 <ENTER>

     •     Type the following to login into the Telnet session: (Note: Entries are case sensitive.)

     •     Obtain the latest version of the release software from the Leitch website and follow the
         instruction to upload the files.

     •     When completed, put both Def. IP and Failsafe dip switches at the back of the X75 unit to
         the UP position.

     •    Reboot the frame.




                                                                                             Page 11 of 17
10. No display on Control Panel.
   There are three possible causes:
    (a) The failsafe switch is turned ON.
    (b) Bad C38 on Control Panel assembly.
    (c) Defective VFD (Vacuum Florescent Display).

   Solution:
   Case A
     At the back of the frame, if the F.S. switch is placed in down position, the X75 frame will not boot
     up properly.
     When this switch is set to down position, it suspends its runtime code and opens only the FTP
     port for the file transfer.

      Please restore this switch to up position and re-power the frame to see the frame boots up
      properly.




   Case B

      Some of the earlier shipped X75 and X75-RCP units, we have experienced premature failure of
      capacitor C38 (part # 101-000067-00) made by Vishay (part # VJ1210Y334J(K)XBAT) resulting
      no display on the VFD (Vacuum Florescent Display) screen. The ECO #TO8212 was released to
      replace this 101-000067-00 capacitor with another vendor.

      Leitch warrants those affected customers during the Warranty period therefore if you contact
      Leitch customer service with the Serial Number and the original PO number, the front control
      panel assembly exchange will be granted for the free of charge.

      The whole front panel assembly part number is 170-000483-00.

      The failure nature of this C38 capacitor is it slowly builds up the resistance in inverse way that
      eventually shorts out the power line supplying the power to the VFD. The resistance across this
      capacitor should be more than several thousand ohms but the failed capacitors were measured
      below several hundred ohms.

      The VFD will function without this DC filtering capacitor so if you are in a panic situation to use
      the frame or want to verify if this is the case, please carefully remove or replace this capacitor.




                                                                                              Page 12 of 17
  Replacement

  The front control panel of X75 does not require any special programming or configuration.
  Therefore, without the needs of replacing the entire frame, user can request for only the front
  control panel for the replacement.

  The user needs to pull the frame 2 inches from the rack and remove 14 screws total from the top
  and bottom of the front panel assembly. When all 14 screws are moved, the front panel can be
  detached from the chassis by gently pulling the panel forward. There is a mating connector on the
  left side of the chassis.

  Please refer to the “Installing a Frame-Mounted Local Control Panel” section of the manual for
  the details.

Case C

  If you have checked the C38 to be good but still no display on VFD, then it is most likely that the
  VFD itself has gone defective.

  The Leitch’s VFD part is 123-000003-00.

  It is recommended that the customers to return or exchange the whole front control panel
  assembly (170-000483-00).

  Please contact Leitch customer service for the RMA.




                                                                                        Page 13 of 17
11. Upgrading the X75 frame in Failsafe mode

   Problem:
   Many attempts were made to update the X75 frame’s software but having a problem connecting via
   network and updating the files.

   Solution:
   It is most likely that the file system got corrupted and in this case, updating the frame is possible by
   utilizing both Failsafe and Default IP switches.

   At the back of the X75 frame, there are two piano switches labeled “F.S.” and “Def. IP”.
   Set both switches in DOWN position and re-power the frame.

   Note:
      When the Def. IP switch is set to DOWN position on power up, the IP Address changes to
      192.168.100.250.
      Please configure your PC’s network setting to be on the same static network and use the
      CrossOver Ethernet cable when connecting a PC directly to the frame or a Straight Ethernet
      cable when the PC and X75 frame are connected on a network hub or a switch.

    •     Open up a DOS Command Prompt box and ensure you can PING the X75 frame from your PC
        by issuing the PING 192.168.100.250 command.
    •     Go to the directory by issuing the Change Directory command.
        Note: Assuming you had downloaded and unzipped the latest X75 frame files to C:\X75Frame
        directory.
        Eg:     CD \X75Frame <ENTER>
    •     While in X75Frame directory, execute the following batch file:
        Eg:     X75frame 192.168.100.250 <ENTER>
    •     Wait about 10 minutes until all the files are loaded.
    •     When completed, set both “F.S.” and “Def. IP” in UP position and re-power the frame.

    Note:
     The Network setting of the X75 should have been retained but if not, go to the
     System Config Setup menu and change/validate the settings and it is critical to execute the
     “SAVE IP” function from this menu.




                                                                                              Page 14 of 17
12. Recovering from incorrectly updated frame.

   Problem:
   Accidentally executed x75RCP batch file to a x75 frame and the frame is not booting up properly.


   Solution:
   The x75 frame needs to put into the FailSafe mode.
   At the back of the frame, beside the Ethernet connector, there is a two positions piano switch labeled
   "F.S." and "Def IP".

   Setting the "F.S." switch to DOWN position and re-powering the frame forces the unit in FailSafe
   mode where it allows the user to re-download again.

   Please refer to “Upgrading the X75 frame in Failsafe mode” section in this Troubleshooting Guide
   for the details.

   Once you have successfully updated the frame with the proper files, set the "F.S." switch back to UP
   position and re-power the frame for normal operation.

   Note:
      The Network setting of the X75 should have been retained but if not, go to the
      System Config Setup menu and change/validate the settings and it is critical to execute the
      “SAVE IP” function from this menu.




                                                                                           Page 15 of 17
13. Recovering from incorrectly updated RCP.

   Problem:
   Accidentally executed x75frame batch file to a x75-RCP and the Remote Control Panel is not booting
   up properly.


   Solution:
   When the incorrect frame files are loaded into the x75-RCP and the panel is rebooted, the VFD
   screen will not display anything and none of the buttons and LEDs will be lit.

   It is most likely that the RCP is in FailSafe mode with the factory default IP Address of
   192.168.100.251.
   (Holding down the BYPASS button for 3 seconds on power reboot forces the RCP into the manual
   FailSafe mode.)

   Please follow the instructions below to resurrect the RCP:
    • Use the CrossOver Ethernet cable when connecting a PC directly to RCP or a Straight
       Ethernet cable when the PC and RCP are connected on a network hub or a switch.
    • It is required to set the PC in the same subnet as the X75-RCP with its own unique IP Address.
          Network Settings      X75-RCP              PC
          IP Address            192.168.100.251      192.168.100.2
          Subnet                255.255.255.0        255.255.255.0
          Gateway               192.168.100.1        192.168.100.1

    •  Open up a DOS Command Prompt box.
    •  Issue the PING 192.168.100.251 command to ensure you get the replies back from the RCP.
    •  If you get the successful replies, then proceed with the next step but if not, then troubleshoot
     the networking connectivity.
    • Go to the directory where the RCP files are extracted.
     Note: Assuming you had downloaded and unzipped the latest X75-RCP files to C:\X75RCP
     directory.
     Eg:     CD \X75RCP <ENTER>
    • Within this directory, type the following:
     x75rcp 192.168.100.251 <ENTER>
    • Once completed, please reboot the panel.
     (Note: When the RCP files are restored properly, the RCP's IP Address will go back to its original
     address.)




                                                                                         Page 16 of 17
14. X75 does not respond to the SNMPWalk command.

  Problem:
  After writing back the SNMP configuration settings back to X75 using the CoPilot/Pilot/Navigator
  application, X75 unit does not respond to the SNMPWalk command.

  Cause:
  With CCS CoPilot or Pilot application version 2.99 and Navigator application version 2.1, it did not
  write back the proper Community strings within the x75agent.xnv file.

  Solution:
  Obtain and reinstall the latest version CCS application 3.0 from Leitch and rewrite the SNMP
  configuration back into X75 frame.

  X75 Agent Configuration file manual work around:

   •     Start up a DOS box from the Windows application and go to the C:\ directory.
   •     Use the ftp commands to read out the x75agent.xnv file form the X75:
       - ftp <ip address of x75 frame>
       - User: leitch
       - Password: LeitchAdmin (Note: Case sensitive)
       - get x75agent.xnv
   •     Edit the x75agent.xnv file with a Notepad application.
   •     Goto the [v1v2cCommunityTbl] section and edit the lines as shown below.
       (Note: The public and private community names can be anything.)
       1=public readOnly(2)
       2=private readCreate(4)
   •     Write the edited file back to X75 by issuing the following command:
       put x75agent.xnv
   •     Type bye to exit ftp session.
   •     Reboot the X75 frame.




                                                                                           Page 17 of 17
