A PENSIONER wiped out an entire village's internet for 18 months by turning on his old TV every morning.
The OAP cut the broadband signal for 400 villagers each day at 7am when he switched on his second-hand telly in Aberhosan, Powys, Mid Wales.
Engineers were baffled when the village's wifi disappeared each morning "like clockwork" for a year and a half.
Tests showed the network was working and engineers replaced large sections of cable serving the village, but the problem continued.
An investigation revealed a burst of electrical interference in Aberhosan at 7am each day, which was traced to a home in the village.
The pensioner's ancient TV was emitting a single high-level impulse noise (SHINE) – which causes electrical interference in other devices.
The owner was said to be "mortified" to find out his old television set was causing the outage.
He agreed to turn off the TV and never use it again.
The picturesque village now has a stable broadband signal.
Engineers used a monitoring device to locate the fault.
Michael Jones, an engineer for Openreach, said: "We walked up and down the village in the torrential rain at 6am to see if we could find an 'electrical noise' to support our theory,"
When we pointed this out to the resident they were mortified that their old second-hand TV was the cause of an entire village's broadband problems
"And at 7am, like clockwork, it happened. Our device picked up a large burst of electrical interference in the village.
"The source of the 'electrical noise' was traced to a property 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.
"As you can imagine, when we pointed this out to the resident they were mortified that their old second-hand TV was the cause of an entire village's broadband problems."
Suzanne Rutherford of Openreach said other household electrical devices can also hit broadband supply.
She said: "Anything with electric components – from outdoor lights to microwaves to CCTV cameras – can potentially have an impact on your broadband connection."
She advised people to ensure their electrical appliances are properly certified and meet British standards.
