The Kameleon HD modules make extensive use of surface-mount tech-
nology 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 module power and signal present LEDs.
• Verify power at the voltage testpoints at the front of the module and
check Fuse F1 if no voltage is detected (
Figure 60 ).
• Check for presence and quality of input signals.
• Verify that source equipment is operating correctly.
• Check cable connections.
Refer to Figure 9 on page 16 for the location of PWR LED and Table 1 on
page 16 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 at the front of this document for the
Grass Valley Customer Service Information number.
