Service
The 2000A89 modules use surface-mount technology to achieve compact
size and adherence to demanding technical specifications. Circuit modules
should not be serviced in the field.
If your module is not operating correctly, proceed as follows:
■ Check frame and module power LEDs.
■ Check for presence and quality of input signals.
■ Verify that source equipment is operating correctly.
■ Check cable connections.
If the 8900 module is not receiving +12 or -12 Volts, check the Adaptor
module’s Fuse F1 (see
Figure 7 ).
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 Group representative for depot location.
Refer to Contacting Grass Valley Group at the front of this document for the
Grass Valley Customer Support information number.
