Hi, my husband wall mounted our sony bravia and in doing so had to cut
the power lead to enable him to chase it into the wall. He added an
inline connector to the main power cable but when he went to turn it
on i think it blew the fuse in the TV, is that easy to fix or will it
have to be done by a proffesional? Also what sort of conector should
we use to ensure it doesnt happen again?
Any advice would be appreciated.

Your IP indicates you are posting from the UK.

This sadly sounds like your husband had some issues determining
differences between wiring colours and their function, and ended up
connecting things the wrong way round to damage something. This can
happen to anyone.

It's probably not going to be a fuse that has blown - you'd have to get
a tech to look at it. That disheartening noise was something else ;-(

It's not immediately clear how miswiring the power cord could damage the
set. There is no "polarity", per se, to AC, nor is there any way one might
connect the wires to increase the voltage (that I'm aware of).

There is 'polarity' if it has an earth wire and the op connected mains
live to the sets ground.

Do we know which country the OP is in?

My point was that it's not like reversing + and -. Why would reversing hot
and neutral damage anything?

It wouldn,t, but not everyone is in the USA and some sets in Europe are
earthed (grounded)

In the USA it shouldn't do any damage or result in a safety hazard with
modern equipment. And unless you checked the wiring of the outlet,
probably wouldn't even know.

If he connected Hot to Earth Ground, it would trip a breaker or GFCI, or blow
a fuse.

Everyone responding seems to assume that the power cord is AC mains; some sets
(such as my Polaroid LCD2000) use a power brick and a DC cable to the set; the
O.P. may have miswired that cable after cutting it if the set is DC powered.

The OP posted through Google Groups with an IP address of
90.204.168.58 which resolves to the UK, but does it matter? The TV has
to meet safety standards which will not let a TV have a hot chassis. No
current production TV is going to have a hot chassis unless some moron
wires the line directly to the safety ground. That would trip a
breaker, or more likely in the UK, blow a fuse in their ring circuit.

UK by the looks of it. I don't know of any Sony TV sets which have a mains
earth connection, and even if they did, wrong connection is unlikely to blow
any internal fuses or do other internal damage. As far as I know, Sonys use
a 'conventional' SMPS, and these care not a jot which way round the mains is
connected, or even if it has a 'live' and 'neutral' at all, as in they work
just the same when they are on a fully floating transformer safety-isolated
bench supply.

The failure of the set to work now is, in my opinion, either as a result of
the connector being wrongly wired mechanically, resulting in a blown plugtop
fuse (we have small cartridge fuses in the power plug in the UK), or just
good old Murphy's Law coincidental bad luck. Bear in mind that if the set
has run for months never going off any further than into standby, then
coming back on from a full power off condition, is the most common time for
a switcher to fail ...

This highlights the issue of a non qualified person taking the "cheap" way out
and trying to do a wiring job about which he obviously knows absolutely nothing.
What he did was highly illegal. You never "chase an appliance power lead into a
wall and connect it via an in-line joiner". The right way is to install an
additional power cable run from the wiring in the ceiling space (or add a new
circuit from the distribution box if required), to a general purpose outlet on
the wall behind where the TV is to be mounted. The power cord from the TV set is
never cut if it is too long, but simply coiled up and tied with a nylon cable
tie or similar. You are going to have a problem trying to explain to a repair
tech just why you cut the power cord in the first place.

"How do you stop it happening again?"

Answer: Don't interfere in any way with the appliance, as supplied by the
manufacturer, if you want to preserve your warranty.

Was there any sound when it was switched on, pop or bang? I don't know
if they do have an internal fuse these days. Even if there is it
shouldn't blow even if it is wired wrongly. You say 'inline connector',
what type of inline connector and is it fused?

How does the tv connect up to the household mains, is it through an
extension cable that plugs into a normal socket? It must have a low
rated fuse in there somewhere.

Do you have power at the 'inline connector'? How is the cable fixed
into the wall? Could the cable have been damaged by the fixings?

The problem with chasing appliance leads into the wall is that you have
to plaster again when you replace them. Much better to put a socket
behind the unit as Ross says and plug it in there.
