518860 2007-01-25 17:02:00 Check out the AQUOS ( . sharpusa . com/products/AQUOS/" target="_blank">www . sharpusa . com) first . . . . . (65 inches is available!)

Plasmas will burn in very quickly, and all the time they are generating any very high contrast, they are actually burning then too .

In 1 year, the optical output is diminished so badly that many people think they are just getting old and going blind . Plasma has a long way to go in reliability yet .

CRTs are actually faster at rendering action, plasmas are the very slowest . . . . LCD's are someplace in between

Life expectancies are (in order of longevity)


1) CRT
2) LCD
3)
4)
5)
6)
7)
8)
9)
10)
11) Plasma

Plasma also requires more correct viewing angles, so does viewing LCD and large projection systems . LCD is more forgiving though for oblique viewing angles .

Plasma likes darkened rooms like in a theater, bars (pubs) and funeral homes as does projection .

Plasma runs considerably hotter than LCD . Plasma pulls more electricity than LCD or even CRT .

518861 2007-01-25 22:57:00 I just have to say: I love my plasma.

Yes it uses more power, yes it runs hotter, yes it doesn't render as fast as CRT.

BUT...

Yes, it's bigger than an LCD, and yes the image generated is WAY, WAY better than any LCD I've seen showing standard TV broadcast, and it works fine in my lighted lounge, and it's better than any LCD I've seen at oblique angles.

But then.... each to his own. :)

I am unsure where you have got your figuress for Life expectancies, however LCD is supposed to have a longer life expectancy than CRT . It however would depend on the brand, and LCDs haven't been around for long enough to really know . One thing I have noticed is that LCDs can delaminate over time . LCDs will also get more reliable with LEDs being used as the backlight in new generations .

For the time being, that is highly doubtful IMO .

Ten HDTV Myths
...

"Burn-in will wreck your plasma HDTV within a year."

The plasma display has advanced since the days when most of us saw plasmas only at airports, where constantly switched-on screens showing formatted flight information suffered from burn-in--ghost images that linger on screen despite no longer being transmitted.

Today, vendors rate the life expectancy of high-quality plasma TVs at 60,000 hours. That works out to more than 20 years of use if you watch 8 hours a day, 365 days a year; it's also about the same lifetime claimed for LCDs and CRTs (the latter are similarly prone to burn-in because, like plasma TVs, they depend on phosphor-based displays).

What changed? Phosphors and gas mixtures in the new plasma panels greatly reduce the risk of burn-in, and some sets use burn-in prevention software. "If you're not worried about burn-in for your CRT, you shouldn't worry about it for your plasma TV," says the Society for Information Display's Larry Weber.

518865 2007-01-26 02:42:00 Make sure it has HDMI interface. This incorporate HDCP, which Sky and NZ will use when HDTV comes out. KiwiTT_NZ (233)
518866 2007-01-26 07:17:00 Just about 1 hour ago, I returned from the ol' trusty Wal-Mart where they have many . . over 300 lcd and plasma and crt-type screens all running . . . so let's get it on butthead . If you want to see the slow death of plasma, try it in a store that has more than an occasional screen set up for the customers .

Life on a display for customers 24/7 (this Wal-Mart is a 24/7 store) is not a good test for anything . . but it sure gets a lot of viewing time compressed into a few weeks . They are never turned off while on display .

The Plasmas are all every one of them . . . not an exception to what I am stating . . darkened and have burnt images from previous screens while on floor display . . . eat well while your head is where it is .

A couple of the Plasmas had color shifts that made the reds, pink and the blue more aquamarine .

Now . . the Plasmas have tremendous amounts of heat . . so much so that the you cannot feel the air conditioning in the area where the plasmas run There were however over 40 of them in the store and that could make it hotter than your home might become . . . . the CRTs are not much cooler . . but the LCDs (over 90 of them running on display) are quite a bit cooler although not cold by any stretch of the imagination .

Plasma brands I viewed:


Hitachi
Pioneer
Panasonic
Phillips
Samsung
LG
Pioneer
HKT
Vizio (probably the best resolution and least fussy on angle-of-viewing)
Toshiba
Fujitsu
NEC
Gateway

LCD brands I viewed:


Sony (Bravia . . . wow factor is high here too)
Phillips
RCA
Akai
Panasonic
Hitachi
Zenith
Sharp (Aquos . . the best I've seen so far)
Polaroid (yuck factor = very high)
Hyundai (UGH!!!)

Most of the CRTs were very good . . . but who wants old technology!

The LCDs mostly all have very sharp resolution, even the 800's and 1,000's . . but of course, the 1200's are the best in resolution . Colors were powerful . . some to a value too high for me to be pleased, but I imaging that they can be adjusted a little lower .

Some with 600 resolution had murky resolution that was very obvious . . . like the 1/2 burned out Plasmas . There is a remarkable amount of distortion though on some of them . . Polaroid the worst . . . eveyone looked like they had heads made from flat pumpkins, even some of the big $$ ones were warped and squashed .

The Sony projection units need almost directly in front of the screen viewing angles . Colors were muted and softer than real-life . . . . disappointing . There were however, only 4 of them on display . . . maybe there'll be a few more at Sears tomorrow to see . Like I said . . I am shopping to buy here .

The Plasmas have the same problem, but not to the same extent . . . . they like the audience to be in approximately perpendicular seating for the best viewing . Sitting (or standing as I was) at more than 15 degrees from right angle produces moire patterns and strange color shift that persons with rectal-ocular vision might not notice . These also need a theater-like darkened room for maximum viewability .

I primarily was concentrating on the 37 inchers but some of the 65's were nice to see too although out of my $$ range . I looked at and touched and felt them for over three hours tonight . . I think that accounts for a valid viewing .

The best screen . . and one without distortion and egg-shaped heads and drawn out and flattened scenery was the Aquos by Sharp . . . it also had some very high resolution . . . 1200 . The blacks were true-er than most of the other 299 screens on display . The flare of reds and fast action scene shift blurring was less obvious too on this unit . The Aquos is also fairly $$$! . . . no wonder . . they have a really good set here .

I was not impressed with the Polaroid units at all . . . even those with 1000 resolution . . . the faces were all squished and distorted and the afterglow of the last scene was still obvious in shifting to the next scene . I thought Polaroid would be a lot better . . . they weren't .

All these units have been on display for at least since just before Christmas . . . and the plasmas were all trashed and turning muddy and less distinct in color and saturated all over the place with what looked like spray painted scenes where they couldn't stay between the lines .

Plasmas suck as far as I can see . . . and they cost about on par to the LCDs . If running since Christmas has caused them to get this bad . . . then I'll keep my money and let you recommend them to people who will actually listen to you and don't mind bad advice .

But then again . . I only have my eyes to tell me what looks good after a few weeks of 24/7 display/use . . . and I might be totally dorked, as I am so described .

518867 2007-01-26 08:17:00 That was rather restrained Surferjoe... can't say that I would have held back as much as you.... ain't nothing so sad as rude people :yuck:

Good ol' NZ is a bit behind the times compared to the US... plasma screens are pretty much 1:1 with LCDs on the showroom floors here although LCD seems to be gaining.

I was in a large dept store the other day and they had a top of the range Philips Plasma on special from $9,995 to $3,000... have to ask yourself why :horrified

PS Being dorked could be considered cool in some circles :)

518868 2007-01-26 09:52:00 Just bought Sony Bravia 2 weeks ago at Harvey Norman (Botany Downs, Auckland). Was not able to get a good price at Mt Wellington Branch. 20% off the LCD TV, 25% off a Philips HD DVD player, 50% off HDMI cable and 50% off a TV rack. Had checked prices at Bond & Bond and Hill & Stewart. Hill & Stewart's deal's quite close. Taurus (9579)
518869 2007-01-26 22:45:00 wow! looks like i missed a bit of input while i was out shopping!
well, after 2 days of research and going thru endless shops and sales people i bought the Toshiba 37" LCD and i must say i am very pleased with it. i got it from harveys for a total of $3100 with a 5 year warranty. even got them to throw in a nice glass tv stand.
it really pays to shop around! i was playing off one shop against another until i ended up with that deal. they are all just screaming to get your money.
once again, thanks to all for the info/input.
cheers!
