Thor 0.8 Digi package 11823 H and 11843 v 30000 issues

Hi everyone,
For some weeks above Digi HD channels have not been clearing properly( flickering image) on my solo SE( signal is up and down like a yoyo)but other channels are clearing fine with over 80% signal quality.
I thought I would doublecheck with spare Techno 5402 HD before looking at dish and found same issues on this receiver too even tough I have strong signal on those transponders
Can someone confirm it is alignment problem before I get the ladder out: thanks :

I have just been having a look and all seems fine, m4 sport hd ok on 11843 and 11823 digi sport hd hu ok all glitch free.
