Another little post that seems worthwhile sharing with the world (at least for Telenet customers in Belgium/Flanders region).
TL;DR;
The Telenet CI+ card works on the Samsung UE40C7700WSXXN (using firmware T-VALDEUC-3018.1).
Long version
Imagine that LED flat screen TV in the bedroom, mounted to the wall, with only a power plug and a coax connection hidden behind. Then Digital TV becomes available and there is no room for a power hungry STB (cable setup box).
Luckily, Telenet allows (since a few months at the time of writing) its customers to buy a CI+ card that plugs into the TV (see TV met een kaartje) at the price of 69 euro (one time buy). However, apparently a lot of (typically pre-2010) televisions with a CI+ slot do not work with the Telenet CI+ cards. So, to prevent complaints, Telenet provides a list with 'certified' televisions that were tested to work. The Samsung UE40C7700 was not on this list.
At the risk of wasting 69 euro, I bought the card and it works fine. I did perform a firmware upgrade first (before even trying anything) to version 3018. Subsequently, it's just a matter of following the provided steps and waiting. It basically comes down to tuning in all the available channels (via DVB-C) and only then inserting the CI+ card. It took about 20 minutes before the encrypted channels became view-able.
Piece of cake :)
