To add to my previous, I don't suppose you've moved anything around in your roofspace, especially anything metalic?
Also check you don't have any HDMI leads behind your set running close to aerial or flyleads, especially when the latter aren't quality double screened coax. HDMI can cause interference but especially to C55 - COM7.

E Chartres: RTE1 and RTE2 are broadcast on the NI mux (along with TG4 and RTE's Irish language radio station) from various transmitters in Northern Ireland, including a low power transmitter at Divis, although there is a higher power transmitter nearby at Black Mountain which covers most of Belfast and large parts of the surrounding areas. Most aerials pointed at Divis will also be able to receive the NI mux from Black Mountain, the low power NI mux transmitter at Divis is there to fill in gaps in coverage.
