how much energy does a plasma use vs a lcd?

also when the tv is off but plugged in how much energy does it draw?

Love me some google.. here ya go: http://www.digitalversus.com/duels-...nergy-consumption-lcd-vs-plasma-tv-ap654.html

Each TV is different but in general a plasma will use a lot more energy than an LED/LCD.

As far as idle goes for your TV, check in your manual for the specs as it varies by TV too.

What TV model?
Did you look at the spec sheet?

my 50" plasma pulls about 200-300w from the wall according to my kill-o-watt in power saving mode its about 120w.

Good lord...200-300W?? That seems insane! Time to get an LCD.

For comparison, a new 50" LED backlit LCD only uses about 40W.

lol been debating on it, paid $400 for this a few years ago and shes doing great, been trying to convince the wife we need a 65" LED, the convincing has been going not as well as id like. but things could change, tax returns are in a few months. who knows. maybe the plasma might... "die" or something..

i have never hooked a kill-o-watt to one personally but from what ive read that number is closer to 70-90w. even straight from energy star.

1st google result...http://www.rtings.com/info/lcd-vs-led-vs-plasma/power-consumption-and-electricity-cost

The chart displays the average typical power consumption for 2013 models as advertised. This isn't the maximum power consumption.

There may be some at 40W... but it seems that at least 2013 models are almost 70W (see link above)... @ 55"

8th result from google.... https://www.energystar.gov/index.cfm?c=most_efficient.me_tvs_over50_inches
link on the page that goes to this page.... https://www.energystar.gov/index.cfm?c=most_efficient.me_tvs_35to50_inches



edit: but idk who knows lol, i like beer. lets have a beer.

I like the energy star link! It seems that use goes up on screen size (as expected really).

Anyhoo...!

You MONSTER! Lol, hey, if you need to have someone take it off of your hands I could give it a good home. I have a 42 inch panasonic plasma and I have yet to find a TV I like more than it. Things just look so good on it.

The 40W figure was actually measured on a 50" 4K Seiki. I think the reason it's so efficient is because they don't go overboard with the video processing (the scaler only does well with integral factors) and design it to be more or less just a simple display. A few years old 55" Samsung (LED backlit) uses about 70W, and an even older 32" no name (CCFL backlit) uses 45W. Little LED backlit 22" and 24" seem to be around 15W to 25W.

Something else to note is that while "blackle" and other white on black text does save energy on plasma and OLED, it does not on LCD. It is also noted that especially if you set most text to be white on black, switching from plasma to LCD purely for energy savings doesn't pay off in any reasonable time. A screensaver or automatic power saving is always a good idea on plasma and to a lesser extent, OLED.

There's a Panasonic 50" LED 1080p screen for $199 coming up for Black Friday sales at Walmart, if you want to save a little.

Standby = 0.3W
Typical = 78W
Maximum = 299W

That's per the specs on Samsung's website.

how does this compare to lcd? i assume about double?

Here's a typical 50" LED TV
http://www.samsung.com/us/video/tvs/UN50EH5000FXZA

Specs say:
Standby = 0.3W
Typical = 47W
Maximum = 121W

Got curious, plugged the 47" LG LED TV to a Kill-a-watt, reading abt 60W displaying Directv program.

Power use would also change when you properly calibrate both technologies.... In general a plasma will use at least twice as much. Who here leaves their screens at default settings? lol

This gives a quick example of what I mean,

I have a 42" Samsung LED TV that I got last year. It pulls around 30-40W, little more when using more wifi/smart TV functions. Overall not to bad.

Then I have a older 55" Vizio that pulls around 100W under I'd say typical conditions from my kill-o-watt meter.

Wow thats an old article, good example on power consumption / price to run it. Bad example for price on TV's
