Find your local electrician's supply shop. And explain properly and in detail your problem. You may
actually have 'iffy' wiring because since it's the UK that *should not* happen on account of UK wiring
being probably to the best standard in the world. You probably need a proper electrical test and
certification if switching on a TV set can **** things up. Wouldn't surprise me in the USA though.

The wiring in this place is pretty old. There's still some old sockets
with round connectors dotted around the place, but I don't think they're
wired up.
