Unplug it and wait a while before plugging it back in.

Does it try to come out of standby, and then drop back ? If so, first thing
to try is unplugging the backlight inverter board. Failure of these is very
common, and will cause the symptoms if it does at least try. The sound
output chip is another suspect for this type of failure.

If it doesn't even try, this can be a power supply fault, but I have also
had mainboard failures cause it on other sets from this stable. To be
honest, if it's anything more than *really simple* on an LCD TV, you're
unlikely to get to the bottom of it. In the last few weeks, the prices of
19" sets has crashed in the electrical barns and supermarkets, so it might
in the end be more economic to just replace it.

Sorry, to hijack this thread, but I notice that Matsui is a Dixons
supermarket brand (with a fake Japanese name). What is the support
like for these off-brand appliances? Will Dixons or their service
agent (do they have one?) supply service literature, spare parts, etc?
Do they limit their responsibility to honouring the warranty (by
repair, replacement, or refund), and then leave the customers to their
own devices?

Here in Australia I've purchased several different appliances from
Aldi but I've never been able to obtain a service manual for any of
them. I've always had to do my own research and reverse engineering.
On the plus side, many of the appliances have proven to be hackable,
with the result that I've often ended up with more than I paid for.

It's a bit 'hit and miss' on the service angle, Franc. In theory, you can
get service info from the Dixons Group. Friend of mine is a service agent
for them. They seem to use independants, and dictate the terms. They did
also have their own in-house service that a friend of mine from the 'early
days' worked for, but I'm not sure if they still do. A lot of warranty seems
to be handled by exchange, if the part required is not going to be supplied
FOC by the manufacturer. You are right that the Matsui thing is just a
Jap-sounding name, but on the whole, the stuff is not the worst you're ever
going to come across. Some of their TV sets and VCRs have been very
long-lived, and obtaining parts was not much of a problem. Thing is, the
stuff is so cheap now that it's hardly worth worrying about service once the
warranty is out. I was looking just the other day at a 22" fully featured
LCD TV for my newly remodelled kitchen. Built in Freeview receiver, HD,
1000:1 contrast ratio etc etc. UKŁ179 ! That was from Argos and was some
'never-heard-of' brand, and you would probably say that being in the trade,
I ought to know better, but c'mon ... 179 quid ?? Got to be worth a punt at
that hasn't it ? Anything lost really, if it's naffed-out after 2 years ?

Arfa,
I sympathise with what you say here, and from a purely practical
consumer standpoint it is hard to disagree. However, this throwaway
approach is somewhat abhorrent, and has environmental costs which are
borne by us all, through taxes for waste treatment and public
recycling schemes - the manufacturers have only a limited liability
for what happens to their shoddy junk when it expires.

A lot of time and money are needed to deal with the after effects of
this mentality. And worse still, it is particularly the poorer folk in
the third world who bear the brunt - the drive for more raw materials
(metals, minerals etc) leads to civil wars and instability in places
like the congo for example. To keep the costs of our monitors, tvs and
dvds down, whole countries end up being privatized (or should that be
privateered!) and the wealth from their resources exported.

It's not only the production process, but hazardous e-waste from the
first world often ends up in slums in India and Nigeria where the
local water supplies are contaminated....the list really is almost
endless when you look into it a bit.

Anyway, not having a pop at you, my intention is just to comment on
the situation we're all in. but I think more people should be aware
that their buying decisions do have consequences, affecting people
unseen by them. B

I hear what you're saying, and of course, I agree in principle. However, I
have to make a living repairing this junk, and it is unfortunately necessary
to make the call that a piece of kit is not worth repairing, more and more
often these days. Just think about it. If you own a TescoSonic home cinema
system and it stops reading discs, you are probably going to bring it to
someone like me. Before we even start, you are going to baulk at having to
pay my time to look at it. Then when I tell you that I can't get the laser
that it needs anyway, you are just going to chuck it in the bin, and buy
another with a shiny new 2 year warranty on it. Even worse is when you pay a
coupla hundred quid for say a Panasonic system, and that one fails just out
of warranty. This time, I can get the laser from Pan, but it's going to cost
you Ł115 trade, and then I'm going to charge you another 35 quid to fit it.
The sums just don't work out. Not your fault. Not mine. Just the way it is
now.

At least the legislation and basic structures are now in place to recycle
this stuff,(weee directive) and it is the manufacturers who are responsible
for the costs of this, not the taxpayer directly (although I guess that the
manufacturers will be building the costs into their wholesale prices to
their distributors)

It is also a little unfair to level criticisms at the consumer and the
repair trade, for causing the stuff to go to an early grave. This should be
levelled at the manufacturers. It's also not my fault, or yours, that kit
gets shipped to third world countries for dismantling, and that the job is
not done in a way that preserves their environment. If you feel really
strongly about it, you should be lobbying the governments that allow the
recycling directives to be implemented in this less-than-ideal way.

Oh, and you're OK. I know that you're not having a go at me ... d;~}

I'm thoroughly disillusioned by the lack of quality in any brand these
days. Like you, I reckon I may as well buy something cheap and not
expect much, rather than expect a lot from a name brand and then be
disappointed.

Anyway, I'd like to know why a service manual isn't automatically
included on the same CD that contains the user manual, bundled
software, etc, especially these days when everyone is focused on
saving the planet. I've tried to interest my local Green politicians
in these kinds of issues, but they're either too stupid, or too
preoccupied with their more politically visible agenda such as plastic
bags and CFLs.

BTW, in an email from our local garbage collection contractor, I was
advised ...

"Thanks for taking the time to use our website I spoke to our
Supervisor and he advised the best way to dispose of fluorescent lamps
is just in your normal garbage bin"
