Symptom 

Reason 

Possible solution 

No picture/black 
picture (factory 
picture). 

Not all connectors have been 
reconnected to factory head-
unit or monitor after 
installation. 

Connect missing connectors. 

No power on CAN-bus box (all 
LED CAN-bus box are off). 

Check power supply of CAN-bus box. Check CAN-bus 
connection of CAN-bus box. 

CAN-bus box connected to 
CAN-bus in wrong place. 

Refer to the manual where to connected to the CAN-
bus. If not mentioned, try another place to connect to 
the CAN-bus. 

No power on video-interface 
(all LED video-interface are 
off). 

Check whether CAN-bus box de12V ACC on red 
wire output of 8pin to 6pin cable. If not cut wire and 
supply ACC +12V directly to video-interface. 

No picture/black 
picture/white picture 
(inserted picture) but 
factory picture is OK. 

No picture from video source.  Check on other monitor whether video source is OK. 

No video-source connected to 
the selected interface input. 

Check settings dips 1 to 3 of video interface which 
inputs are activated and switch to corresponding 
input(s). 

LVDS cables plugged in wrong 
place. 

Double-check whether order of LVDS cables is exactly 
connected according to manual. Plugging into head-
unit does not work when the manual says to plug into 
monitor and vice versa. 

Wrong monitor settings of 
video-interface. 

Try different combinations of dips 7 and 8 of video-
interface. Unplug 6pin power after each change. 

Inserted picture totally 
wrong size or position. 
Inserted picture double 
or 4 times on monitor. 

Inserted picture 
distorted, flickering or 
running vertically. 

Video sources output set to 
AUTO or MULTI which causes 
a conflict with the interfaces 
auto detection. 

Set video source output fixed to PAL or NTSC. It is best 
to set all video sources to the same standard. 

If error occurs only after 
source switching: Connected 
sources are not set to the 
same TV standard. 

Set all video sources to the same standard. 

Some interfaces can only 
handle NTSC input. 

Check manual whether there is a limitation to NTSC 
mentioned. If yes, set source fixed to NTSC output. 

Inserted picture b/w. 
Inserted picture qual. 
bad. 

Picture settings have not been 
adjusted. 

Use the 3 buttons and the interface's OSD to adjust the 
picture settings for the corresponding video input. 

Inserted picture size 
slightly wrong. 
Inserted picture 
position wrong. 

Camera input picture 
flickers. 

Camera is being tested under 
fluorescent light which shines
