The 8911 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 input signals
■ Check cables and connections
■ Verify that source equipment is operating correctly
■ Check output connections
Refer to Figure 5 for supply voltage test points on the 8911 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.
