Service
The 8920DAC 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 directed by Customer Service to do so.
If your module is not operating correctly, proceed as follows:
■
Check frame and module power and signal present LEDs.
■
Check for presence and quality of input signals.
■
Verify that source equipment is operating correctly.
■
Check cable connections.
Refer to
for the location of PWR LED and
for proper LED indications.
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
