it amazes me, u see all these huge tvs for sale, yet, when u ask how much electricity these things use, u get an embarassed shuffle, and off they go to find a manager who hasnt got a clue either, i red in tv mag these things can use up to 600 watts, frightening,.

That's what put me off Plasma, although they do act as a radiator in the winter. ;)

LCDs are better, I now have a 40" Samsung LE40A656 which is rated at over 200W, but the once-calibrated figure recorded in the HDTVtest review is 99W, which doesn't seem too bad to me.

My missus bought one of the Owl energy monitors for £10 in a car boot this morning, been playing with it all day :)

My TV, sat box, Vbox, Freesat PVR, Media player plus 2 external hard drives in the living room are consuming just 32w on standby, which has settled a long running argument about leaving them on. The LCD TV draws about 100w, Samsung 37".

32W "only" in Stand By is a lot of wasted energy ... in fact it is 1KW/h every 31 and 1/4 hours (every less than 1 and 1/2 days) !!!

with my lg the only option is stand-by or turn off at mains

no on off switch

apparantly this is designed to use very little power in stand-by ?


anyone confirm ...

Probably more like 200W

Spec below is from Samsung
LE37A686M1F

Power Power Device Power supply - internal Power Consumption Stand by / Sleep 1 Watt Power Consumption Operational 220 Watt

Some Samsung 37inch LCD use nearly 300W according to manufacturers spec.

All manufactures should have how many watts they use on their site :respect-051:

Once you know that you can easily work out how much it will cost

Your energy provider charges you by the kilowatt an hour

Theres a thousands watts in a kilowatt so you just divide the watts by 1000 then multiply that by the price you energy provider charges an hour

Say they charge 10 pence a kilowatt/hour and your TV uses 400watts

400w divided by 1000 = 0.4kWh multiply by your providers rate of £0.10 per kWh = £0.04 per hour

Think thats right but its late and I'm tired :ack2:

400W = 0.4KW and if you use it constatly over 1 hour it becomes 0.4KW/h. No such thing as 400W/1000 equ 0.4KW/h .....

Yep I have an LG LCD 42" with NO on/off switch. If you turn it off it has to be unplugged at the mains which I don't like. I think it uses less than 1watt on standby. In this day and age and with all the issues about global warming (obviously bollox but thats another argument) you would think ALL electronic companies would have to have an On/Off switch on every electrical appliance. No complaints about the LG though, lovely HD picture.

Depends on how it is setup m8, with the energy saving option enabled, I have just checked again and it draws about 118w, assuming the test kit is accurate ;)

All the other appliances I have checked come in on spec as regards power consumption, so I'm guessing the tester is reasonably ok.

@gmcinema - 32w is about £2 per month assuming it's continuous @8.9p/kWh which is what I'm paying. Bending down to switch them off at the socket every night would cost me more in chiropractor's bills than that :) - Also, you can't record stuff when it's switched off at the mains...

Yep, as mrbleu says, settings make a big difference.

The manufacturer has to state the maximum possible figure, but calibrated consumption can be less than half that with LCDs.

I said it was late and I was tired which is why I had it round the wrong way theres a thousand Watts in one kilowatt

400w = 0.4kw

Go to the link below and type in 400 next to watts then click convert and look at the result next to Kw

If you don't believe you can calculate how much it will cost using the method above I'm not going to try and convince you otherwise

No need for a website m8...

32w = 0.032kw (1000w =1kW)

0.032(kW) * 24(h) * 7 * 4 = 21.505 kWh used in one month

21.505 kWh * 8.9p = 191.39p per month

Less than £2 ;)

In actual fact the kit is on for 10-12 hours a day so the real cost of the standby usage is less than a quid a month...
