Problem
Possible solutions
Pressing the PWR key doesn’t power up
the unit.
•
Check the fuse and the power to the head.
The control head powers up, but not the
processor (the processor’s power indica-
tor at the back of the unit isn’t on).
•
Check the fuse and the power to the proces-
sor.
•
Check the coax cable between the head
and the processor.
•
Set the TEST-POWER switch on the pro-
cessor to the “test” position. If the processor
doesn’t power up, then power to the proces-
sor is faulty or the processor’s power supply
may be defective.
The control head powers up, but there
isn’t any video.
•
Verify that the processor’s power indicator
at the back of the unit is lit.
•
Check the fuse and the power to the proces-
sor.
•
Check the coax cable between the head
and the processor.
