X75HD/X75SD Installation and Operation Manual 231
Appendix B: Troubleshooting
Video Conversion
Performing an HD cross-conversion but can’t see the
down-converted signal
Problem
The X75HD is taking 1080i input and forcing the output HD standard to
720p for cross-conversion, but the down-converted signal is not present
at the SDTV outputs. There is no visible SDTV content.
Solution:
The unit does not have the softkey option that makes it possible to
perform simultaneous crossconversion and downconversion. Purchase
and install the X75OPT-HDDUOCON software key option.
Follow these steps to purchase and install the HDDUOCON option:
1. Confirm the option is not installed by following this path:
System Config>Status/Version Info>S/W Options
The word
HDDUOCON will display if the option is installed.
2. If the option is not installed, follow this path to find and record the
unit’s serial number:
System Config>Status/Version Info>Serial Number
3. Contact Leitch’s sales department and then purchase the option.
Enter the softkey using either an X75HD/X75SD control panel, the
X75HD/X75SD Web Browser, or a CCS software application. (The
valid key character sets are numbers 2~9 and letters A~Z.)
To enter a softkey number using the control panel, follow these steps:
1. Select System Config>Setup>License Key.
2. Use the control knob and the Enter button to enter the characters.
3. Press the Exit button when completed.
