Service
The 8949SVM modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit boards should not be serviced
in the field unless directed otherwise by Customer Service.
Power-Up Diagnostic Failure
If the module has not passed self-diagnostics and the FAULT LED remains
on after a valid signal is applied, do not attempt to troubleshoot. Return the
unit to Grass Valley. See
Module Repair below.
Troubleshooting
Electronic Circuit Breaker
An electronic circuit breaker on the module works during a fault condition
or an overcurrent to cut off power to the module in place of a fuse.
If power has been cut off to module, remove the module and replace it in
the frame to reset. If the problem persists contact Grass Valley Customer
Service.
Module Repair
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 Customer Service representative for depot
locations.
