Service
The 2041EDA modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser-
viced in the field unless otherwise directed by Customer Service.
Power-up Diagnostics Failure
If the module has not passed self-diagnostics, do not attempt to trouble-
shoot. Return the unit to Grass Valley (see
Module Repair ).
Troubleshooting
If your module is not operating correctly, proceed as follows:
• Check frame and module power. If power is not present, check the fuse
on the module as illustrated in
Figure 6 .
• Check for presence and quality of input signals.
• Verify that source equipment is operating correctly.
• Check cable connections.
