I have the same kind of issue. Ziggo is my provider and I am using the CAM module Ziggo send me.

The problem is that I dont get any picture at all. The screen stays black altho on the upper left corner it does say what the name of the channel is that i am currently watching. (i.e. Nederland 1HD etc).

The only error message I get is: No programme available.

I have been on the phone 3 times with Ziggo to no avail and they told me in the end to contact Philips.

I have updated the TV's firmware to the latest version(6 oct 2011) and checked the cables, cards etc to rule them out.

Ideas anybody?
