It is a little unfortunate that I read your original post too late as I have already done my regular weekly tour of my local computer mall this afternoon. I am almost (90%) certain that this model T27A550 is being sold and on display. If I have come across your first post earlier, I could have checked this CI slot for you and may even be able to take a couple pictures with my phone.
I will do my tour again, perhaps on Friday or Saturday. So, if you can wait a few more days, I might be able to offer a few pictures. No promise but I will keep an eye on that TV for you.
I did a little search in the net and I come to think this CI+ slot is only available for T27A550 in certain countries because this is a digital broadcasting standard. So, if a country does not have such standard, Samsung will sell a T27A550 without this slot. But Samsung will sell a T27A550 with this slot if that country has this standard.
For a list of countries with this standard, see:-
These countries are European countries but this list is probably not up-to-date because the Samsung link quoted by me above is a United Arab Emirates Samsung website. So, I suppose UAE also has this digital broadcasting standard.
I do not think my country has this standard. But I will still examine a local T27A550 to see if it has the CI+ slot.
