After I softmodded another wii again, the two remotes don't work anymore!

I tried to delete the wii-remote synchronisation records, a new sensorbar and another wii remote: no result. After testing the sensorbar with another softmodded wii, I can say that this sensorbar works fine, including the two wii remotes.
I think my Wii has an internal software problem which results in a negative synchronisation of any wii remote.

Is there anyone who knows a little more about this problem?
