Problem started when I purchased a new Samsung widescreen TV. My partner
then complained for weeks that everytime I turned on the TV the internet
connection slowed down or completely come to a stand still, my first opinion
was that my partner was losing his marbles as how can a TV interfere with
the internet.

On weeks of listening to his moans and groans I looked into the problem,
support lines thought I had lost the plot, last resort was to request
telephone tech to check line.
Apparently indeed to my wonder everytime telephone tech did turn on the TV
the phone line would pulsate and hum and clear when TV was switched off,
telephone box had to be replaced down the other end of the room and
completely baffle tech.

Now I indeed had to suck up with cups of coffee for doubting him and as I
was ready to send him off to the people in the white coats.
 
Greetings --

The phenomenon is widely known as Electro-Magnetic Interference
(EMI), and has long been the bane of network administrators working in
industrial environments. The problem is described in all basic
networking literature, and I'm truly surprised that a qualified
telephone technician could possibly be unfamiliar with it. Poorly
shielded electric motors, fluorescent light fixtures, and other
electrical devices emit magnetic fields and sometimes even stray radio
frequency (RF) signals that induce stray electrical signals/currents
in any unshielded network cabling within range. These stray currents
are interpreted as "noise" by data systems, and can severely degrade a
network's performance.

Now, should your new TV be "broadcasting" signals strong enough to
interfere with data and voice signals over telephone lines? I
certainly shouldn't think so. It's almost as if you've turned your
home into a large microwave oven. There may even be health
consequences. Does the TV carry a warning not to operate it in the
vicinity of anyone using a heart pace-maker, for instance? You should
probably check this with the TV's manufacturer.

yes. it's magnetic interference. Probably got some large speakers with that
large TV too. Don't put your computer close to the tv or the speakers
either. It could mess up the monitor.
 
Thanks to all for replies,
Well I never, no wonder am I losing my memory slowly but surely, am only
cooking it and hears me thinking I was getting old.
