EX 1000 SL - picture breakup, some channels, low signal level - advice?

Would have been my first thought, apart from reading around suggests the 82/83% I'm getting on most of the muxes is regarding as too high and can cause breakup issues of it's own...

Ok a quick test with a 10db attenuator produce expected results - it completely kills the relevant mux/channels, they can not even be displayed. Lowers most other muxes to around 70-75% signal level, with a couple of muxes remaining at around 80%. I've obtained marginal results tweaking the frequency very slightly (0.100Mhz increase appears to help a little) but still regular breakup. I'm assuming at this stage I'm looking at incoming signal issues, not quite sure how to tackle this.

Tested all the sockets in the flat (5 sets) - huge variation. Found one giving an extra 100 channels, so looks like series signal loss either in the flat wiring or in the DA which I don't have access too...
