Highline failure

Yes, they look fine to me. As the fan isn’t running, im thinking that there isn’t any power getting to the unit. What pin powers up the video module? If I can get power to it I was wondering if I could prove the modules.

Black connector with blue cover, pin 1 is a permanent feed of 12v from the car's battery. The earth is pin 10.
There is a separate earth for the LCD display on pin 12.

I’ll have a try later to see if it’s the modules, board monitor or car.

Nope still getting the same result with both video modules. Blank screen, backlit with a blue line on the right hand side.

Hi to all
have a look at the wry cable there is a header under the carpet on the drivers side 2 members have reported that fault was found on this header try and see if you have continuity from the front to the back the wry cable goes to the video unit

Hello Graham,

Did you prove that +12v is reaching the video module connector?

David is referring to the K-bus connection between the screen (Bord monitor) and the video module. It's colour coded white/red/yellow and you'll find it on pin 3 of the video module connector (black with blue cover) and on pin 6 at the screen connector (black with natural cover).

Please let us know how you get on.

Graham looked in on the 3rd February but gave no response to this thread.

Maybe he doesn't know how to find the replies to his questions.---
