Toshiba 40XF355D convector heater

My eyesight isn't quite what it was, so I want a TV with a good sized
screen that doesn't dominate the room.

So when I saw the 40 inch Toshiba 40XF355D in Currys.digital with its
remarkable frame barely thicker than 2cm, I was very impressed.

I was not so impressed when I leant over it to look at the connections
down the back and caught its stream of hot air in my face. It is not an
exaggeration to compare it with a convector heater, and it would be truly
unacceptable to be in the same room as the thing on a hot summer day. LCD
TVs are bad like this, but leaning over other TVs in the store showed me
that the 40XF355D was at least twice as bad as the 42 inchers.

Why the hell should LCD TVs be like that anyway? My laptop that I'm
typing this on has an LCD screen and that's sealed and yet feels like
it's at room temperature.

Here's the spec for the 40XF355D. All the specifications for the TV
proudly provided by Toshiba -- except, strangely enough, the power
consumption, which is marked TBC (to be confirmed, I presume). Well, I
can confirm that it's a bloody disgrace, Mr. Toshiba.

I think it might be that Toshiba have to wait for measurement in the UK.
There is a figure quoted by various non-UK retailers: 243 Watts at

There's no reason, legal or otherwise, for them to wait if it's the same
model. 243W seems far to low for the amount of heat that it was pumping
out in Currys.digital. It's more likely that the figure got withdrawn
because it was found to be wrong, or it only applied to early models (as
is often the case with specifications), and it was too embarrassing to
replace it with the correct figure.

Went into the local PC World the other, moderately warm, day - it
was like an oven. It crossed my mind to ask them why they'd got the
heating on, but instead I asked: "Why is it so hot in here?" The
replay made me glad I'd asked that question and not the one that first
crossed my mind: "Because of the machines, computers, TVs, etc ... we
don't have air-conditioning in here!"

TVs are bad like this, but leaning over other TVs in the store showed me

Really? My understanding, and experience of the first, is that they
are better than CRTs and Plasmas in that respect.

Panasonic TX-15LT2 15" LCD: Use 49W, Standby 4W
Sony KV-16WT1U 14" CRT: Use 52W, Standby ??

I don't know all the law and practice (including Toshiba in-house
practice) on such things. But if you are right then Toshiba are as
inefficient as you believe their TVs to be since they are quoting the
figure of 243W on their official German site -
http://www.toshiba.de/consumer/files...s/40xf355d.pdf.

Might it just be that 243W is quite enough to generate a good flow of
warm air on a warm day inb a warm shop?

It's probably nothing to do with the LCD. It's the processor and other
hardware inside that does the processing. If you look at your laptop,
you'll probably find some vents through which the fans are pumping warmish
air to cool the processor.

Now put a DVD into your portable, let it run for a while and then check the
temperature coming out - a lot more I'll bet because rendering DVDs (or
Freeview) takes a lot of processing. Now add properly upscaling and/or
handling HD (was this the Freesat TV?) and the temperature keeps rising.

I work for a firm of computer programmers and there's a reason I refer to my
PC (pentium 4 based) as a "room heater".

I have a greenhouse heater rated at 120W under my desk, and it feels really
warm under there when it's on. I have two 80W greenhouse heaters in my
motorhome shower/toilet and they warm it up a treat.

I lit my gas ring in my work van the other day and because the sun was on it
I thought it had blown out, so I put my hand over it to confirm this. In
fact it hadn't blown out. I now have no hairs on the back of my left hand.

I have an Alpine radio/CD player and when I take a disk out you could fry an
egg on it (well, a blackbird's egg probably because CDs are really too small
for a hen's egg).

My Sony DAB radio/CD player, however, actually cools the discs down to 0deg
C, and when I take them out, if the music has not been to my taste I can
snap the disc into pieces due to its brittleness and push the segments up my
arse to cool my haemorrhoids. This also has the purpose of helping me
express my feelings about the artiste.

Different problem to the TV. Lots of relatively simple electronics in a
small, confined space (I presume the Alpine is a car system).

You're obviously better at snapping CDs than me. I get sharp edges which
would be far from soothing ;-)
