My current 50" TV is not even a high end plasma but picture quality in terms of contrast, viewing angle and blacks it still better than any sub £1000 55" LCD.

Unfortunately the TV has started developing some faults any will probably need replacing soon. Any thoughts on best alternative. Main thing with LCD is the viewing angles, even IPS screens can't match it.

Would have thought Oled is your best bet, if you dont want the downsides of led/lcd tv's.

Hi there, whatever you do do don't do Plasma again they are greedy when it come to energy usage, i had a client complaining about his electric costs, he was leaving his plasma on for about 18hrs a day @ 450watts an hour, it was only most for background noise he soon changed his viewing habits after that.

Plasmas are dead, they are not manufactured any more.

Later plasmas averaged nothing like that much energy, it's an old wives tale best ignored. When I last checked mine, it averaged about 150 watts or less. A couple of old style light bulbs. Obviously, if someone's been stupidly racking up the brightness contrast and other settings to maximum like they did in shops, it would be more - but still nothing like what you suggest at typical screen sizes (42-50 inch).

Yep!

I don't know about the current models but LG seem to have a flickering problem when switching between 1080i and 1080p. See threads on this issue where LG don't want to know and several members have vowed never to touch LG again.

Not at all, Plasma do use considerably more energy - obviously they don't continually use what the label on the back says, that's the absolute maximum consumption - just as the label on the back of any TV is the absolute maximum.

But you don't even need to measure what a Plasma uses, you can physically feel the heat coming from it

So at least during the winter it's not 'wasting power', as it's heating your house and reducing your heating bill slightly.

Which is a number of times higher than a similar sized LCD set

But you are disagreeing with and 'correcting' things I didn't write or suggest!

I'd have thought everyone knows plasmas use more energy than LCDs but the better comparison is with 2 or 3 incandescent light bulbs, not an electric heater.

Even 450W is well short of an electric heater

If that's all you can find to quibble about I assume that you agree with everything else. Cool.

He can beat that if he wants! 400 W. https://www.amazon.co.uk/Econo-Heat-...dp/B002ZFJ86K/

I'd love to go OLED but at current prices it out of my price bracket. Guess I'll keep go going with my current screen for now.

Also my plasma is around 450W when display bright screen and around 200W when showing a black screen. I believe LED are the other way round, more power used to power the LED when displaying a black screen and less with a white screen.

OLED screens (self-illuminating pixels) ought to vary their consumption in the same manner as plasma displays (albeit at a lower level).

LCD screens with LED backlighting (or cold-cathode backlighting, for that matter) ought to show a fairly constant consumption, regardless of screen brightness (because the backlight remains at the same intensity whether you can see it or not).

LCD screens with local dimming backlighting would reduce consumption with a darker picture, but I can't think of any technology that would increase it.

Its not the backlight that causes power fluctuations for a non-dimming LCD screen, the crystals themselves require a small amount of power in order to twist and block the light to create a black pixel.

I suspect that would be negligible compared with the power consumed by the backlight. But I can always be persuaded with numbers...

It's wasting money though as electricity costs around 3 times the cost of gas that is normally used for heating.

All this talk of energy is pointless. The energy used to manufacture the TV and the costs of you buying it are huge compared to the energy costs of running it. If you really want to be environmentally friendly don't buy a new TV.

Good point. Now factor in the fact that no new plasma TVs have been manufactured for several years so any purchase of one now will have to be previously owned. Clearly plasma is now a very environmentally friendly purchase option for anyone contemplating a replacement TV.

Not at all, almost ALL LCD TV's dynamically dim the backlighting, only the very early ones didn't.

Less than negligible

LCD's take almost no current at all, it's essentially a static field (a bit like the charge on the grid of a valve).

What does take a reasonable amount of power (but far less than the backlighting) is the chips driving the LCD, these have to work very quickly, so produce a fair bit of heat.
