Sony Bravia TV...What should I do??

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).

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.

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.

If live was connected to the sets ground, then any gounded metalwork

What's inside the set shouldn't care. It should blow the fuse or
pop the breaker or GFCI upstream.

Most civilised countries have legally enforcible laws requiring that electrical
wiring be performed according to specified standards, and usually, alterations
must be carried out by a qualified electrician - even in your own house.

Since the OP is in the UK, this is particularly so.

I don't know of any Sony Bravia LCD TV which is powered by anything but ac mains
power. My Bravia certainly is.

In the Uk it is not 'highly illegal' to modify a mains lead on a Tv
set! stupid in this case, yes, but not illegal!

Do we know which country the OP is in?

Ron

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 ...

That's a very good point. Sometimes, the marking of the two wires in the
figure 8 DC cable, is not especially clear, and may not be at all, to
someone who is not experienced in knowing what to look for. That being the
case, he may well have reconnected the wires backwards. Hopefully, the set
wouldn't care and just sit there inert, but it may also employ a shunt
protection diode, which may fail itself, or knock out a fuse. The brick
would of course be a switcher itself, so a reverse connection to the set on
its output, may just result in the PSU going into an excess current shutdown
condition.

Precisely. The set wouldn't be damaged.

Modifying the appliance lead may not be illegal, but "chasing" it into a wall
and then connecting it to the mains supply via an "in-line joiner" is. The
appliance must be connected to the mains via an approved outlet which is
accessible so that the appliance can be unplugged. I doubt that an in-line
joiner (was this also chased into the wall?) which, from the OP's description,
would not be easily accessible or would not allow the appliance to be unplugged.

Here in the USA it is illegal to run any appliance's power cord inside or
through a wall. (National Electric Code)
No matter what country you're in, the correct way to install your TV on the
wall without the mains cable visible is to install a new outlet behind the
TV. Depending on your local and national electric codes this connection
should be made using Romex (Solid conductors covered by PVC sleeve) or BX
(Armored cable).
In some cases it is safe to tap into the nearest power outlet for this
connection, but there are a lot of variables including how many
outlets/fixtures are on the same circuit, how much amperage is being drawn
on that circuit, etc. For example, you do not want your TV plugged into the
same circuit as a refrigerator, air condtioner or other items that cause a
large power drop when they start up.

If the TV has a standard removable power cord, replace it with a new cord
and test the TV by plugging it directly into a wall outlet. If it works
then you have probably not done any damage to the TV. If it doesn't work
you should take it to a repair shop and have it repaired. Next, HAVE AN
ELECTRICIAN INSTALL THE OUTLET BEHIND THE TV FOR YOU. It may seem expensive
at first, but a qualified electrician won't burn down your house, destroying
your property and perhaps killing you and your family.

Interesting thread. When I bought a dishwasher I tried to get an
electrician to connect it. He wanted to tap
into an existing outlet on the backsplash behind the sink. I told him to
piss off, added a run of BX to the
breaker box and added a new breaker dedicated to the dishwasher. Doing it
myself might not have been legal,
but it was a hell of a lot safer.

I've had the same sorts of experiences with licensed so-called
professionals. My 70 year old water main split. I dug the entire 35'
from the house back to the...Oh Spit! Someone had planted a tree smack
on top of the line!

My wife, not believing I'd see the project through quickly enough,
called the 'pros'. They came out the next day with a backhoe, intending
to trench 'around' the tree...warning me that it would surely not
survive the process.

According to Code hereabouts, a water main is allowed only one 90 degree
joint, where it turns to go under the house. Not only were they going
to kill my tree, they planned to go around the tree, putting three more
elbows into the system. (The meter was only five feet from the tree.)

Fortunately, when they arrived, there was a car parked right in the way.
I told them to take their machine away, come back the next day and I'd
have the excavation done and ready for new pipe.

I excavated the pipe on the far side of the tree, cut it off on both
sides and worked the stub out from the house-side. Before the hole
could collapse, I threaded a garden hose through it, under the tree. My
thought was that I could turn on the hose (my neighbor's) and wash out a
larger hole with it.

It proved unnecessary. The plumbers arrived and after much
head-scratching (and a threat to get sent away again), decided they
'could' get the new copper through that hole--and did. We used the same
trick to get under the house foundation and into the basement, turning a
$1600 job into a $400 one--and to Code. (I needed their sign-off to do
the meter connection--and to mitigate the $1400 water bill I got the
next month.)
