In Reply to: RE: Why are manufacturers moving away from Plasma ? posted by Ross on December 03, 2011 at 11:57:13
My new Panasonic Palsma, 50", List $1500, does not get hot or even warm really, and we were told it would use $24 / year electricity, based on 5 hour a day. We use it less.

Assuming only 3 hours a day at about 300 watts operation, that's around one kilowatt hour per day, if in 365 days you only used $24 worth of electricity, the per kilowatt hour price would have to be $.065... who on earth pays only six and a half cents per kilowatt hour? 5 hours operation would mean 4.4 cents per kwH.
Either you were misled, or your TV is much more efficient that any other 50" plasma on the planet, or electricity prices are artificially low where you are.....

Your numbers do not match Panasonic's numbers for their 50" Viera S30. Remember, plasmas are seldom listed with average power numbers -- they nearly always list max power draw. That's not fair because power draw fluctuates with on screen brightness with plasma (average ≠ max). LCD, on the other hand, has very little power draw fluctuation (average ≈ max).

I wouldn't expect realistic energy use numbers from a manufacturer any more than realistic fuel eff. numbers from the auto manufacturers!But to be fair: so you're saying that a plasma screen doesn't often use the max power?
Also, power prices in the US do seem to be lower (artificially so, I might add) than in the rest of the world. I'm in NZ.

Actual power draw with a plasma display depends on program material.
However, plasmas are rated at the max power draw. This is based on a completely white screen (this basically represents "full on" mode). So the question is, how often when a display is in use do you have a completely white screen?
Not only that, but it also assumes that brightness and contrast are at max levels. If you calibrate your set (and you should), the levels will never be at those max settings. Todays plasmas usually consume less energy in a typical situation than LCD/LED types.
That's what salespeople and fanboiz are for.
Our 50" Panasonic doesn't get hot, either. You have to almost touch the screen to feel any warmth at all. The 'heating' of Plasma TV's is way over-hyped, in my opinion.
I have a friend with a 5 year old Samsung Plasma, and he says when you get near it you can feel the heat. I was told the new ones (Panasonic) solve that ( as we can attest!) and the energy use. We'll see how that goes, hoping for the best. The Plasma TVs I saw were WAY better than any of Sony Bravias, etc.
I had a 42" Toshiba plasma set that I bought in 2006. It put out tons of heat, so much so that I had to run a window air conditioner in order to operate it in the summer (I don't have central air). The picture quality (720p) was fine except for horrendous macro blocking in dark areas. I replaced it with a Samsung 46" 1080p set that makes no heat, has better picture quality, and cost a LOT less than I paid for my old TV. I didn't even consider plasma sets due to the weight (over 110 pounds versus 40 pounds) and the heat.
110 lbs vs 40 lbs? What does a wall or decent entertainment center care? So weight has no relevance, unless you hold up your display. Which reminds me of a very short conversation I had with a Best Buy "team leader". He was trying to impress two of his underlings about DLP vs plasma. He started going on about the "advantages" of DLP sets and actually picked up a 43" Samsung to show me how little it weighed. I said, "That's nice, but most people either put their displays on an entertainment center or mount them on the wall. Not too many people hold their display in their arms when it's TV time." . The other two started laughing so hard they had to walk away.
He never spoke to me again.
As for heat, I never owned a Toshiba plasma, but my late 2003 model 50" Panasonic is only warm even after hours of gaming from the kids, a Sunday's worth of football games or a movie. Even my 42" Sylvania (made by Funai) from 2007 is barely hot after hours of use. And that's because it has no fans. The 50" Panasonic has two virtually silent fans that can only be heard at startup -- a slight "whirrr" -- but go stealth in about 5 seconds.
Thanks for the tip about the fans, I thought maybe it had a hard drive. The fan whirring is very soft.
The 42" Panasonic plasma I bought in 2007 runs very cool. After watching a long film, when I go to shut it off the air coming from the vents on top is barely perceptably warmer than room temperature.
