Service
The 2090MDC 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 ).

■ Check frame and module power. If power is not present, check the fuse
on the front Media module as illustrated in Figure 13.

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