REMEDY:
-Verify +12 VDC on Red wire at 2 pin Power Harness behind video monitor.
Verify ground connection with continuity test from known good ground to
black wire at 2 pin Power Harness
-Verify that the correct source is selected (i.e.: 1,2,3 or 4). Verify that the
source is on and playing a known good media (such as a videotape). Verify
connections at both ends of the source component harness.
-Push and hold the volume up button until sound is heard over headphones.
If problem is limited to the dash radio, verify radio is tuned to the correct
channel, and that power to the wired RF modulator is on. (Refer to instruc-
tions with modulator kit). Otherwise, verify all connections per the wiring
diagram on page 6.
-Press Auto Program button. Then press CH up or CH down. Verify an-
tenna mounting and connections to the tuner.
Note: Due to the nature of TV signals, vehicle motion, direction the vehicle
is facing, distance from the transmitter, nearby surroundings and weather
may adversely affect TV reception. These conditions may result in the
following: picture roll, "snowy" picture, or momentary loss of color.
-Check batteries in the hand held remote (not included with this kit). Verify
that the IR LED ( page 6 Wiring Diagram) is properly attached to the sen-
sor window of the VCP (or other component).
