execute the command:sh cable rf-status

2 DOWN Yes 0 1 Jan 21 18:17:47
3 DOWN Yes 0 1 Jan 21 18:17:47

turned on and off rf-channel, after 2 minutes again DOWN.

You can tell what could be the problem.

Check your fiber nodes

Perhaps your fiber nodes aren't correct?
This is how ours are:
cable fiber-node 97
downstream Integrated-Cable 8/0/0 rf-channel 0-3
downstream Integrated-Cable 8/0/1 rf-channel 0-3
upstream Cable 8/0 connector 0
!
cable fiber-node 98
