Service
The 8943RDA 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 on page 85 ).
Troubleshooting
Electronic Circuit Breaker
The electronic circuit breaker works during a fault condition or an overcur-
rent which stops the module.
Remove the module and replace it in the frame. If the problem persists,
please refer to the 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 representative for depot location.
