Troubleshooting the Coax Wire:
Weak or no picture can indicate a possible shorted or open coax. The coax
cable is made of two conductors: A center conductor usually of copper and a
ground that is woven of braided aluminum. The "die-electric" insulating
material separates the two conductors. The ground and center conductors are to
remain electrically separate from one another. When installing a F-connector
onto a coax cable, use care so none of the woven ground strands make contact
with the center conductor. A continuity tester is required to test a suspected
fault in a coax wire. Unscrew both ends of the suspected bad coax run. With
the continuity tester, check between the center conductor and the outside
threaded ring. If continuity is present, the coax is shorted. To test for an open
connection of a particular coax run, use one test lead and touch the threaded
end of the coax. With the other test lead, touch the threaded ring at the opposite
end. Continuity should be present. Perform the same test procedure on the
center conductor. Proper electrical coax operation should indicate continuity
from the center conductor at one end to center conductor at other end.
Continuity should be present between each coax terminal end. There should be
no continuity between the terminal end and center conductor. Though damage
does not usually occur from a shorted or open coax cable, picture quality is
compromised.
Front TV - Flat Screen:
A 24-inch Flat screen television with remote control is mounted in the front
overhead cabinet.
Video Cassette Recorder (VCR) Optional:
The videocassette recorder is the same one found in most homes. The VHS
compatibility allows recording and playing back programs on standard VHS tapes.
The VCR component is easily recognized. It can also be used for audio/video
operation for the TV. The VCR will automatically turn on when a tape is inserted.
The Audio/Video Input Jacks in the front allows for quick easy connections of
additional video equipment. Easy Setup procedures provide the flexibility to
quickly adapt the configuration for RV usage.
