LCD sets run cooler than Plasmas, correct?

[NTB]

Just curious. Right now I have a Panasonic TH-42PZ77U Plasma. Originally I had it in the living room of a small apartment, where I never really noticed just how warm it ran.

Fast forward to February of this year: I've moved to take a new job, and the TV now resides in my (much smaller) bedroom. Having the TV on for a while can literally turn the room into a nice little sauna 😛

So, as much as I like the set, I'm considering replacing it, hopefully with something that won't cook me to death while showing a movie. But that wouldn't do me much good if a similarly-sized LCD ends up pumping out the same amount of heat.

Any opinions? Are there maybe certain brands or models I should look at - or avoid, for that matter - with this in mind?

Thanks!

Nathan

my 42" samsung lcd will also warm up a room quite a bit.

Those fancy new Mitsubishi laser-projection TVs are very power efficient. Astronomically expensive, but efficient.

Great 🙁 What model? If I end up replacing the plasma, Samsung's LN40B640 is one of the sets I'm considering - it's on sale at BB this week for $1100.

The other sets on the short list are a couple LGs - the 42LH40 and 42LH50.

I was at a sonystyle store the other day, all of the LCDs output quite a bit of heat. Just walking past them you could feel the heat. Perhaps the Samsung LED LCD TVs run cooler? I don't know, but it is worth checking out.

Not for my pocketbook it's not 😛

Not sure how much of a difference it makes, but in looking up the specs for my own 42" plasma as well as a couple different 40" and 42" LCDs, it seems that the LCDs do draw quite a bit less power - in some cases less than half the wattage.

If your own 42" Plasma is a couple of years old, that is not surprising.

For example

42" Panasonic Plasma TC-P42U1 = On Mode Average Power Consumption 142 W
42" Panasonic LCD TC-L42U12 = On Mode Average Power Consumption 146 W

Comparing these two, was surprising, however. I wouldn't have thought that the Plasma would beat the LCD in the same manufacturer and size.

The TV is an '07 model. From the owner's manual that I downloaded:

Power Consumption - Max: 580W

:shocked:

Sure max = 580W meaning that every pixel is on and is pure white...you can hurt your eyes if you watch TV that way, plus it is rather boring 😉

My Pioneer KRP-500M 50" Plasma uses around 170W with powersave mode 2 on. But it still dishes out heat pretty well.

True, but the smallest LaserTV (LaserVue) is 65" and about ~$6000. 😉

One of the dirty secrets of the industry is that LCD's and plasmas aren't particularly energy efficient, and generate a lot of heat.

So replacing the set won't do me much good? if so, darn 🙁

It will. Old plasmas are way less efficient than current TVs of any sort (plasma just took an efficiency leap this year).

lol 😛 I was going to say...I really wouldn't consider 2 years to be 'old'.

is it possible to "underclock" a plasma tv? is it as simple as turning down the brightness?

 

[manimal]

If you want to cool off your tv then turn the brightness and contrast down considerably. I dont see how people dont have headaches more often watching tvs left in torch mode. If you own a samung start with the movie settings preset and work from there. If you dont mind using some google-fu you can head over to AVSForum and search for calibration settings which will seriously improve yourr image quality and lower heat output tremendously. Your set will last longer as well.

You can purchase the Joe kane essentials disk and it will help you dial in your set as well.

It wasn't set to default - I used the Digital Video Essentials DVD to set the image controls.
