Troubleshooting:
SYMPTOM: | REMEDY: |
No power at Video Monitor | 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 |
Power but no video or sound | 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. |
Static on TV Stations | Press Auto Program button. Then press CH up or CH down. Verify |
(Tuner Version Only) | antenna 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. |
No Infrared remote functions | Check batteries in the hand held remote. Verify that the IR LED |
for VCP (or other components) (page 9 Wiring Diagram) is properly attached to the sensor window of the VCP (or other component).
