I wonder how common this is:

I wonder if the offending TV was close to the Openreach cabinet, or on the same electricity phase as the cabinet.

There was a time when TVs used a thyristor with phase angle firing control, just like old light dimmers, to regulate the main 200V dc power supply. This was a half wave circuit and generated horrendous harmonics on the mains. This was when a proper SMPS would have been expensive. You would have to be 60+ to remember theseWe've* had a good think about this and can only assume it's a nasty switch-mode power supply radiating RFI or feeding it back into the mains. It's hard to think of a fault in a CRT that could radiate that much energy and still work as designed. It's also yet another reason why we shouldn't be sweating the copper lines for broadband.
