Service
The 8914 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 serviced in the field.
If your module is not operating correctly, proceed as follows:
■ Check frame and module power and signal present LED.
■ Check for presence and quality of input signals.
■ Verify that source equipment is operating correctly.
■ Check cable connections.
■ Check output connections for correct I/O mapping (correct input is
used for the corresponding channel output).
Refer to Figure 4 for supply voltage test points on the 8914 module.
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.
