Download Installing DEC/DES6800+ Modules

Appendix A: DEC6800+ and DES6800+ Troubleshooting
d. If there are bent pins carefully re-position them to their correct
positions.
If this is not possible then you can exchange the back module
for a new back module. Use part number DES6800+DR.
5. If the DES6800+ can still not be genlocked, attempt doing a Factory
Recall on the module.
Output Issues
If the SDI output has issues such as no output, unstable output or frozen
output proceed with the following checklist.
1. Check that the Video Standard Select parameter is set correctly.
This is normally left in Auto mode, but if 525 or 625 mode is
selected and then the wrong input standard is applied, the unit will
not pass good video.
2. If the video output appears to be soft or unstable, check the Decode
Mode parameter. If Notch is selected this may cause softer video.
The Notch filter is normally only needed with poorer quality video
sources, so try setting this parameter to Auto or 2-D Adaptive
mode. In Auto mode it will automatically switch between 2-D
Adaptive or Notch depending on the quality of the input signal.
3. (DES6800+ only) - If the video output appears to be frozen check that
the Freeze Mode parameter is not turned on. When this parameter
is set to On, the DES6800+ will freeze the last video frame or field
that was received.
4. (DES6800+ only) - If the video output appears to be stuck on black or
color bars check that the TSG parameter (Test Signal Generator) is
not enabled.
5. (DES6800+ only) - If the video output appears to be unstable it may
mean that the source is non-time base corrected. Try turning the
TBC Mode parameter to Enable.
