Sudden "ci+ module or smartcard not recognised" alert

[Members_GFmVs85]

The tv in the retirement home I work in suddenly started giving this message on most channels. It always worked fine until 2 days ago when this became an issue. Tried looking for the channels again and a factory reset but everything stays the same, we have the exact same tv on another floor (same signal/provider) and that one still works perfectly. What could possibly be the issue?

Hi @Members_GFmVs85 ,

I think that this post may respond to your question and provide you with the steps to sorted this out: Solved: Common Interface - Samsung Community

If this doesn't help, please do share the TV model here so I can try to look for an alternative solution. The model can be found at the back on a white sticker.
