5. TROUBLESHOOTING

The system does not work

A fuse may be blown. Replace the external fuse with a fuse of the same value.

The power wires may not be connected. Check the wiring connections and retest.

No picture.

Press SOURCE to make sure the proper input is selected.

If there is still no picture, press PICTURE. If the menu appears, check the source unit and video connections. If no menu appears, check all fuses and power connections to the monitor and the associated equipment.

Note:

The monitor has an operating temperature range of

-1oC to 45o C (30o F - 113o F). If the temperature is outside this operating range, the unit will not turn on, or the screen may be slow to react to image changes. The monitor will function normally once it returns to its proper operating range.

With a DVD player and a widescreen DVD disc, there are black bars above and below the picture.

Change the TV display mode to “Wide” in the DVD player’s Setup menu.

After changing this setting, if there are still black bars, press WIDE on the front panel of the monitor and select WIDE.

The screen is dark

The brightness is set too low. Press PICTURE and adjust the BRIGHT option.

The interior of the vehicle is too hot or too cold. The monitor’s operating temperature is -1 degree to 45 degrees Celsius (30 degrees to 113 degrees Fahrenheit).

Picture “rolls.”

Check that the VIDEOSYS setting is correct for the monitors and DVDs being used (see “Changing the Video Output Mode”). PAL video often “rolls” on NTSC monitors.
