The 2041RDA 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 as directed by Grass Valley 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 ).

If your module is not operating correctly, proceed as follows:
• Check frame and module power.
• If module power is not present, check fuse F1 (see Figure 11 ).

• Verify that source equipment is operating correctly.
• Check cable connections.
