Troubleshooting and Maintenance
Troubleshooting
Display shows a blue screen:
Check the cables for obvious damage (i.e. cuts,
crimping) and the connectors for corrosion or pin
damage. Make sure connectors are securely
connected and free of debris.
If spares are available, swap out one item at a time;
the camera, controller and associated cabling.
Display doesn’t light up – dark screen:
Check the red and black wires at the controller to
make sure they are properly connected to the
vehicle power and ground. See if proper voltage is
reaching the controller.
See if the fuses on the controller are okay. If not,
replace with new fuses. The green LED on the
controller will be illuminated if the individual power
circuit is functioning properly. (See specification
section of the controllers operation guide for the
proper fuse rating).
Make sure connectors are securely connected and
free of debris. Check the cable for obvious damage.
There should be no continuity between any of the
wires inside the cable. If shorting has occurred, the
display and controller should always be returned for
service and the cable replaced.
Picture is blurry, out of focus or distorted:
Check the camera and clean any dirt, dust or
moisture found on the outside glass lens cover.
If
any moisture is visible on the inside of the
camera, remove and return the camera to INTEC
for service.
Adjust display controls (i.e. brightness and contrasts)
to see if picture clears up.
Check voltage on the red power wire to see if
sufficient power is reaching the controller. Low
voltage may cause the picture to blur or darken.
I’ve experienced a short in my system and after
correcting it my image is reversed:
After a short, it may be necessary to reset the
display software. (Refer to the displays Software
Guide on the Installation and Operation CD for
instructions on resetting the menu).
A continuous tone is heard through the remote
and I have no remote control function:
Turn the vehicle power off for 10 seconds and turn it
back on.
Check to make sure the remote control is connected
properly.
Preventative Maintenance
The most effective way of reducing camera system
failure is regular preventative maintenance. At least
once every two weeks and/or every time the vehicle
is in for its scheduled maintenance is recommended.
Although it would be difficult to cover every possible
scenario, the following are some examples to look
for:
1. Physical damage to the camera. Examples:
cracked camera glass, bent front covers, damaged
casing or brackets.
2. Dirt or moisture on the camera’s glass. Cleaning
the camera’s glass should be done with a clean, soft
cloth to prevent scratching. For excessive dirt build
up, you may need to rinse the camera glass with
water or glass cleaner first.
3. Scratched camera glass. Excessive scratches on
the cameras glass can distort the image. Cameras
with scratched glass should be returned to INTEC
for service.
4. Moisture behind the camera glass.
If this is found, simply removing the cover and wiping
off the glass will not solve the problem. Repairing
the source of where the moisture is coming into the
camera is the only way to prevent it from happening
again. The camera should be returned to INTEC for
service.
5. Damage to the cable and the connector seal. This
includes the main cable as well as the camera and
monitor pigtails. Examples: Cuts or abrasions in the
cable, cuts in the connector seal or a connector seal
that has come loose.
Note: Connector sealing is not required in the XL
and Hirose Camera Series.
