Samsung LT27A950EX/EN

Hi,

I have a Samsung LT27A950EX/EN monitor / DVB-C TV for 2 years and during that time it has successfully been working with my Smit CI+ and smartcard. During that time is the TV was not watched for a while then when you selected TV it would again go through the authentication sequence and then start working. About 3 weeks ago all channels except NED1 and a few Ziggo Info channels have become scrambled and if I reinsert the card I get "Authentication Start" but it goes no further. I have 2 other Samsung Smart TVs with Smit and smartcard and can confirm that the Smit + smartcard work in both of these and that the Smit + Smartcard from those TVs behave the same in the monitor. Signal strength is 100% with BER 0.

I have tried the following: -
1) Factory reset of LT27A950EX/EN without CI+ and then insert CI+
2) All Smit CI+ modules have had their firmware upgraded where required.

Can anybody suggest anything else I could try to get the monitor to authorise the Smit?
Does anybody know is something has changed at Ziggo to cause this problem?

Thanks
Richard

Check and exclude.
Starting with the card reader.
If the chip fails to make contact inside the card reader, you may try and clean it by moisterising the chip a little.
Then slide the card slowly into the card reader. See what happens.
