Well, dug out the box (under floor) with the TV / FM splitter and installed the isolater that the guy had left (way back when the modem was installed for 10MB - had been on BB via the STB). Didnt touch the STB/modem splitter at all, and the modem came up a-ok. (I think, up by a small fraction of a dB from where it usually is, the original connections on the splitter were not very tight)
Could be the STB side cable from the splitter got strained, but also tried giving it the other feed - and yes, I did get the isolater the right way round, the chap had put an extra mark on the input side and drawn a diagram.
PS. Also remembered that holding down does something, and it jumped to LD40 - still didn't get to AP-anything, but I did recognise the dot that goes blink, blink, steady whan it gets backchannel, that came up.
So, gone from many channels unavailable, to LD20 on the STB, but the modem stats are pretty much perfect.

Apart from the old "if something's weak, It'll break at next powerup", as until then the STB had not been power cycled for ages, only ever soft rebooted (hold button... Stop)
