DSTV lost channel 170 after coming back from Holiday and switching to home smartcard

[The Philosopher]

As the title states, channel 170 has been lost since reactivating the home smartcard from the holiday one. Nothing we have tried has worked. I took it into for testing in Randburg, but it worked fine there. Not sure what the issue is. Any advice? The decoder is a HD PVR 2 P decoder! They said the LNB might be the issue. WHen I looked at the signal status Tuner 1 was 0% and Tuner 2 was 100%. When I was at the testing center both were 100%.
