Internet: Old TV caused village broadband outages for 18 months
An unnamed householder in Aberhosan, Powys, was unaware the old set would emit a signal which would interfere with the entire village's broadband.
After 18 months engineers began an investigation after a cable replacement programme failed to fix the issue.
....
Engineers walked around the village with a monitor called a spectrum analyser to try to find any "electrical noise" to help pinpoint the problem.
"At 7am, like clockwork, it happened," said Mr Jones.
"Our device picked up a large burst of electrical interference in the village.
"It turned out that at 7am every morning the occupant would switch on their old TV which would, in turn, knock out broadband for the entire village."
The TV was found to be emitting a single high-level impulse noise (SHINE), which causes electrical interference in other devices.
