When you touch the warm glass the heat is conducted to your skin. You may also feel some convection currents as they go by the back of your hand when it's near the tv, which would be less at the bottom and more at the top.

In otherwords if you can feel the heat from your TV from where you watch you are sitting too close....

Has anyone tried putting a AM radio set to 530 and put the radio near the plasma TV?
It really squeals because of rfi.

Is this acceptable, or bad rfi design?
post #33 of 63
Wow. I think I'm done using towels to dry off after showers. I'm just gonna stand 12-15" in front of my plasma and spin like Wonder Woman til dry.

What are you smoking and where can I get some?

By the way, the tingle means its working.

That doesn't mean a thing. When I listen to AM band on my Geneva XS radio, I can hear the RFI from my Sharp air filter / fan located 5ft away from it.

I think people forget a plasma tv works the same way a fluorescent light bulb does.

How far away from the bulb before you get the "tingle?"

Your concerns are very real. The reason you feel that way is because it is putting out UV radiation greater than the sun at that distance. My baby started complaining of red and green lights in his vision and my older son took his welders mask and confirmed that the discharge from the plasma was more than standing looking at the sun for 10 mins.

A plasma display charges each pixel, then sustains it. The sustaining produces UV from charged pixels, which is converted into visible light by the phosphors. In the same way as a fluorescent bulb or CCFL lets out a little UV, so does a plasma display. The UV light is long wavelength, very close to violet. It has no harmful effects.

I am referring to the panasonic series which you can got 50" plasma at Sams for 600 buck these days. I had two identical sets similar to this only 2008 technology before. I always noticed the heat comming from the screen. In my recent attempts to replace those sets, I have had some serious doubts as to go back with plasma or not. Near as I can tell the energy output/consumption may have improved about 20% in real time, and then more considering the "tune down setting options" to further control their output. Apparently some brands just emit more energy off the screen. The Panasonic has to be the foremost on the market in my guestimation.

So while on the hunt, I stopped in front of the 50" plasma at Sams today just to see if the heat was still comming off the screen, AND IT IS.. Notably, the LG60" I am testing does not put out even half that much all considered. I dont really know why. But with regard to the Panasonic, if you put your hand 2 inches from the screen you can denote heat, and serious heat. But more interestingly, if you put your face even as close as 12-15" from the screen, you can feel a "tingle on your face". I am guaranteeing you THIS IS NOT CONDUCTIVE HEAT you are feeling. I dont know what it is, but I have a suspicion it is some kind of energy radiating off the screen. So I am trying to track down an explanation other than general BS, so that I can ease my concerns.

Any thoughts or input technical or not are appreciated.

you know light is energy right?

stick your face in front of your cars headlights, it'll feel warm too. when I was younger we had this 10 million candle power flashlight on display that we played around with. from 30feet away you could feel when it shining on you.

I don't think plasma TV's are going to turn you into the hulk anytime soon. if anything, it must be emitting more infrared than lcd's do. and well, if you're afraid of infrared, you're pretty much screwed

PS, little embarrassed that I was duped by this old thread being bumped for no reason. damn, feeding the troll. sorry

Plasmas emit enough IR to make Microsoft and possibly other IR receivers for HTPCs blink their red LEDs like crazy. I'm even talking reflected IR, as my receiver is located under the surface holding the TV and is actually recessed a couple of feet. That's something I noticed right away, and someone posted on it in this forum yesterday. Thankfully, they don't turn the IR into random commands, and the IR doesn't interfere with the remote.

weird, can't say I've seen anything like that here, but never put my sensor in front of the tv either.

I have seen the one in my bedroom stay lit solid at times, never thought much of it. but I have a LCD in the bedroom, wonder if it's the lights in the room or something. great, something else to waste my time on for no good reason, thanks for that:p

Thanks for keeping us informed.

I used to press my face against the huge early 80's microwaves, hypnotized watching my food heat. I'm sure I have nothing to worry about compared to that. In fact, I would postulate that Plasmawaves would counteract any such damage I've sustained from the microwaves as a child. JMO.

It's not in front of the TV. It's under the shelf the TV sits on and recessed a couple of feet.

Seen that too from time to time, even before I got the plasma. I just learned to ignore it. For a while I had the receiver sitting on top of a metal case BD player, which was not even turned on. It was flickering a good bit, so I moved it onto the shelf beside the BD player. That fixed it until a few days later, when it started doing the same thing. It was a very intermittent thing until I got the plasma TV, which brings it out consistently. The flickering varies with the APL.

10/10 so much gold in this thread. I laughed HARD.

Very interesting stuff, I was wondering about the factory workers’ health who are involved in the mass production of plasma TV’s

Certainly no worse than most other factory work. For example LCD panels, if cracked, can leak a semi-toxic material, and the fluorescent bulbs in a conventional LCD produce UV too.

This is much like "windmill syndrome" - a very interesting psychological phenomenon, but nothing grounded in scientific fact. I put water fluoridation, chemtrails in a similar (thought slightly more crazy) box.

Part of the perils of the modern age, where a luddite suspicion of technology seems to infect us in surprising ways...

I would be more concerned about the hundreds of pesticides and chemicals in your food and water.

If I had not been out to BJ's wholesale looking at the Sammy PN60F5350 Plasma today, I never would have read this gem of a thread. I have rarely laughed out as loudly as I did reading this one. Hopefully the car is parked and turned off right? Because if it's moving you're gonna be more than a tad warm. Just priceless. BTW...I'm still buying the Sammy 60 incher. At $679 I can't pass it up. It'll be replacing a 65 inch Hitachi 65F59 HD CRT Beast.

After calibration, plasma or LCD makes virtually no difference. However, under vivid mode prior to calibration, LCD is worse to your health (your eyes, specifically) because of the brightness level is so much higher than plasma in vivid mode. Furthermore, because LCD tend to run too blue, uncalibrated LCD panels under vivid mode may interrupt your sleep pattern (blueish light spectrum affect the brain secretion of melatonin which helps deliver quality sleep)

So what you are saying basically if you own a Samsung F8500 you are screwed both ways ROFL

By the feedback in this thread sounds like those Samsung F8500 owners wont be around much longer because of cancer. It in fact after all the brightest plasma ever created

I hope you all are scrubbing

It does not take a rocket scientist to know that when one puts their face near of panasonic plasma screen - ITS "HOT". You can the further remove your face from the screen and feel a definite action on the skin, which I DONT THINK is conductive heat. Its not like typical heat from an over rolling out through the air. AND if there is any truth to the Panasonic being able to "radiate" out a tingle other than conductive heat, and as far as 12-15 inches, then this should be a concern. That would be too much of something. PERIOD.

All kidding aside I am sure if there was an issue than it would be made public by now. Kids love getting as close to these big screens now a days so If there were any health conerns I would like people would know by now...

There was a discussion at some amateur radio forum back in 2002, where several people complained about high frequency radiation from plasma TV's:

lol

I have been using plasma up close for a long time first hitachi and two panasonics

I am still alive and my vision remains at 20/10 last i checked

Haha yes eltsing, the internet is full of "discussions", and if you think something might be a problem - a little googling will confirm that for you, whatever it is you are looking to validate.

I see there where you link to FDA radiation qualifications... ....

It never hurts to question anything right? Thats what separates us from the ALIENS that farm us. biggrin.gif

But Seriously, its a good point you bring with this because it gives me the opportunity to provide an example where a "regulating authority" fails to provide to complete tale. Take cell phone radiation emission for example. While the FDA qualifies and quantifies the criteria first for WHAT is safe, and second - what the amounts (SAR Rating) emitted are. IT IS A COMPLETE IGNORANT FAILURE To believe that cell phone proximity to the body is safe. WHAT THEY LEAVE OUT is the point that cell phones emit radiation FAR in excess of these documented output levels. They do it in BURSTS and in given LIMITED instances. I read an article not too long ago indicating that cell phone radiation emitted goes as much as 10 fold when; (1.) The cell phone is checking tower connections, re-establishing connection, switching towers etc. (2) When a call comes in (and I assume data connections other than audible calls too). (3) Instances of general Service Carrier phone data inquiries/involvement. So imagine if you are in a car traveling and how much tower searching/switching is occurring. If you have ever had your cell phone sitting around in proximity with a desktop computer with a sound system involved, you have probably heard the random "beeping" that sounds like the same pattern every time this happens. I am speculating that these are instances of general phone service provider interactions which are one of these general times not even call related. I recall this is also the same noise that would come through the speakers a couple of seconds before a call would come in as well.

The POINT is to ask and be aware, and if anything, THIS THREAD provides helpful information to some for cell phone safety (to justify my "self-hijack" - LOL). But just imagine ALL THE WOMEN now running around tucking cell phones in their bras right next to their breasts?!!!??!! There is also considerable instance of tumors in the skull which can not be denied as cell phone radiation related. So this is a real issue which no one really knows about. It never hurts to ask questions...smile.gif

Anyway, agreed - no high energy radiation. CRTs do produce x-rays however, which is probably where all the TV paranoia comes from...

http://www.fda.gov/Radiation-EmittingProducts/ResourcesforYouRadiationEmittingProducts/ucm252764.htm

"It is important to note also that flat panel TVs incorporating Liquid Crystal Displays (LCD) or Plasma displays are not capable of emitting x-radiation. As such these products and are not subject to the FDA standard and do not pose a public health hazard."
