The 8960ENC 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 directed otherwise by Customer Service.
If your module is not operating correctly, proceed as follows:
• Check frame and power and signal present LEDs.
• Check module voltage testpoints and fuse ( Figure 25 ).
• Check for presence and quality of input signals.
• Verify that source equipment is operating correctly.
• Check cable connections.
Refer to Figure 7 for the location of PWR LED and Table 2 on page 17 for
proper LED indications.
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.
Refer to the Contacting Grass Valley on page 4 at the front of this document
for the Grass Valley Customer Service Information number.
