OT for a sec: US wiring sources of info

And yep, it's all the old 60A three-cable stuff. The plot thickens somewhat after getting some more info out of the SO and doing some poking around. The problem only happens on certain outlets when the TV and cable box share any of the problem outlets, and the aerial's hooked up between the TV and cable box. (so I was incorrect about it *just* needing the cable box plugged in to cause problems) So it seems to be something to do with the TV and cable box having a connection via the aerial lead that's causing trouble, but only when they're using certain power outlets. The lead between power outlet and cable box is a moulded thing and can only go one way round at either end (the socket's PCB mounted at the cable box, so it can't be mis-wired internally either). The TV has an integral lead, although I tried swapping wires at the plug without any luck (it refuses to startup with them swapped) So it'd seem like some other issue - possibly a fault within the cable decoder of some description, or maybe something else which is sharing the cable feed (there's a cable modem on there too, and also another TV without any decoder in one of the bedrooms) Anyway, still looking for suggestions of places to ask all of this so it's not on the list! cheers Jules
