I have been trying to trace a fault in my boot with the problem being that only one of the rear entertainment screens is working, I would have just swapped over the cables at the entertainment module end but of course they are different coloured plugs (green and black) to rule out a cable problem but I can't.

I've had both seat backs off and crossed the cables there and the monitor does work so it's not that.

I have found that there is only one fibre optic light working no matter which plug I seem to take off, Is this the problem? and if so what part do I need to fix it?

Any help greatly appreciated as there is no-one in my area has the expertise for this.

The Fibre optic is an "in and out" connection. So you should only ever see one working. All the modules are daisy chained together.

Thanks, I was waiting on the thing I would learn today and that is it! My TV doesn't seem to be working either, anybody know which module that one is? The grey one on top?
