This TV must have been putting out a hell of a lot of RF interference.

Electro Fan:
under 4 Mbps is called a Not Spot


“Its low internet speed of 4Mbps meant it was a proper "not spot" where young people could not watch YouTube, the local pub struggled to take card payments and downloading a film was nearly impossible.”
ChristofferB:
Amazing story. Bizarre how little radiated power is needed for a LOT of interference - on a much lower band too.
Cerebus:
Version of this story in the Register here and original Openreach press release here.

TL;DR: "Openreach engineering, after taking over 18 months and using both hands, finally manage to find their own arse.". 

Really, what muppets put out a press release to advertise the fact that it took them more than 18 months to recognise, diagnose and track down a simple EMI problem in a tiny village? Here's the massive area that they had to roam to find this fault, and it took over 18 months:

Not to mention inability of the regulatory body (Post, is it?) to investigate.  Also surprising no amateurs complained.  Though maybe there aren't any in such a small region, and the interference was local enough not to disturb anyone else.

I wonder what the noise was.  High voltage arcing?  Must've been in a pretty unlikely location, where it was able to conduct/radiate.  Or perhaps it was a slightly newer TV, and its EMI filter went tits-up, and maybe failed isolation too, thus transmitting all the switching noise.  Wouldn't seem likely that such a malfunction would still be useful though: could it even receive cable anymore?

Also mysterious that the telecom hardware wasn't able to deal with it.  Surely they test their shite to 10V/m and such?  Maybe they don't use class A criteria (no dropout of service) during such tests.  Maybe it was installed wrong (broken shield somewhere?).

Likely, as with any good disaster, there are multiple causes of failure...
