Bought a couple of cable tuners a couple of months ago for my box.

I have only just got around to fitting them today but the problem is they won't scan any channels in.

I have setup how I think is correct but still no joy

I have a dreambox running with a cable tuner and that works fine so I'm not sure where to start

I have used the line I know works but the venton still won't find anything

Anybody have any info or help

Thanks
