Thanks for the reply, I would suspect it's the mini cable that came with the kit, it is a very small diameter, probably 2mm at the most. There are 2 wires inside, one is for the power & the other I presume for the picture.
The reason I asked is it worked at the the start but now I have no picture again, just a blue screen, so I suspect the join has come undone.
can you upload picture of a cable you have ?
what every cable you have on your system there are many of cable connctors on the market. just you buy both male & female connectors. thats it.
