Home audio & video: Plasma Burn in??
Prose and Consternation
by orthotox - 7/6/07 10:27 PM In reply to: Plasma Burn in?? by TeezerPlasma: burn-ins still an issue, otherwise explain why Pioneer's web site suggests movies be viewed full screen in order to obviate the potential of letterbox burn-in? Think of it: the "ultimate movie experience" that begins by clipping the picture. Brilliant, Pioneer! Also not discussed here: reflection off palasma screens often intreferes with viewing pleasure, whereas the dulled surface of LCD minizes this annoyance. Finally, in a general context, always edifying to see people hot to critique the very best that quality engineering has to offer, while they themselves can't muster even the most basic effort to compose a literate sentence!
Then...
by ns387241 - 7/11/07 10:04 PM In reply to: Prose and Consternation by orthotoxHow do you explain my severe testing of three of Pioneers Plasma Models (PRO-FHD1, PDP-5070HD, PRO-1440HD), testing of which included leaving bright, colorful, paused images on all of their screens with no image burn protection activated. NONE of them received ANY image retention. Burn-in on Poneers is not an issue. I have owned Pioneer Plasmas for the past 5 years and plan on continuing to do so.
Also, FYI, LCD's "dulled surface" is prone to glare in many ways that compriamise picture and ruin a viewing experience so much that it makes small reflections the last of one's worries. LCD's bleach colors when exposed to extreme leve s of light (e.g. The Sun), their black levels show the base color (LCD's can't produce a perfect black, they use very dark colors as a base, whcih look like black under normal conditions), and Don't even get me started on how many problems LCD's are faced with in a dark room! Response Time: Gag me. Who wnats a picture full of compriamises when they can have a plasma insted?
Why not rear projection?
by ben_cline - 7/6/07 11:03 PM In reply to: Plasma Burn in?? by TeezerYou've got your choices between plasma, LCD, and rear projection. For mounting on your wall (looks great), you have plasma and LCD. Both great choices. You have several reasons to either go with LCD or plasma or not. Plasma has a glass front. Easier to break, and causes glare in a bright room. You get a bright picture and great color. The problems that you face could be burn-in and if at a higher altitude, loss of pressure causing pink lines to run through your screen and permanent damage, unless it's sealed, but it's still a problem that I have seen harm a couple televisions in my area (Big Sky, MT). The ghosting is extremely apparent on the cheaper models. A customer of ours cheaped out on a Costco plasma, and it was so bad you could read the background image with "World News" from the news channel he was watching. So if you do decide on a plasma, get a good one. The Pioneer Elites have a great gray-scale, so the dark colors aren't all black. You can get a 940 for just under $2000 shipped. I don't know what your local stores are selling them at. Great price, down from $3300.
LCDs are great. Our biggest seller at Vann's. Response time is lacking, so that's one thing to watch out for. We have at least 30 models on display. Most are no older than a year, and non have or have ever had dead pixels on them. Haven't seen any problems with them, aside from the Sharps that tend to have a split-screen line running through the middle of them. One we have on display in our model meeting room has a horizontal line right down the center. The Sony XBR models are great, as well as the Samsung. Sony and Samsung go together to make the panels (source: Sony Rep), the rest of the electronics and TVs are seperate. Samsung is one of our biggest sellers for LCD, which they also produce plasma and rear projection televisions.
Rear projection televisions have a better response time. Many have over 170 degrees of viewing. The thing that people usually don't choose them for is that they don't mount on the wall. A downfall for projection is that the bulbs burn out. At least that's a cheaper replacement than anything happening to a plasma or LCD. Replacing a screen due to a scratch is a lot easier as well. Check on what your company will do for an extended warranty. Vann's will even come out and replace your bulb at no cost. So your extended warranty ends up paying for itself.
POS screens in America?
by 3rdalbum - 7/7/07 4:09 AM In reply to: Why not rear projection? by ben_clineI work at a Best Buy Electrical in Australia, and I'm very surprised by the descriptions given of various LCDs and plasmas. The TVs we get down here must be different to what you're getting in America.
We Aussies love our sport; we have our own code of football which has a lot of action. Even when watching the footy today, our LCDs didn't really look too blurry. The crowd was blurry when the camera panned, as you'd expect, but the players didn't blur much at all. The LCDs definately look sharper than the plasmas when there isn't a lot of motion, and on our Samsung TVs the motion is actually smoother than the plasmas, because of Samsung's interpolation technology.
I've never seen a plasma down here with burn-in. Not a standard def LG, a high def Panasonic, not even the lowest-of-the-low Conia plasma which has many other problems.
In addition, I've heard Americans raving about how good Hitachi plasmas are, but we had one on the floor that was utterly terrible. We had it replaced, with little improvement. It was fricking heavy, too.
And there's people saying that rear pro gives good picture quality?
It seems to me that the quality of the flat-panel TVs in America must be substandard. Until Panasonic started its campaigning down here, 80% of our customers thought that LCD gave a sharper, more defined picture, from their own experiences looking at the TVs in other shops. Now it's more like 60%, but these people are just going by what Panasonic's advertising campaign has told them.
i think you're reading too much into...
by woodygg - 7/7/07 9:50 AM In reply to: POS screens in America? by 3rdalbumthis.
the lcd panels are the same (there's only a few manufactures of them anyway) - and have approximately the same characteristics of what you described.
Pixel Move
by dodnsa - 7/7/07 5:48 AM In reply to: Plasma Burn in?? by TeezerMake sure you purchase a Samsung Plasma it has a feature
called " Pixel Move " every 5 minutes the pixels move preventing what you call " Burn In ." Plasma's must be kept cool;
HEAT is it's nemesis; have it mounted professionally and have a fan or multiple fans cooling the rear of the Plasma Screen.
If you look at the back of the screen you will notice many
openings to cool the unit; but it doesn't. It's the Motherboard
and it's components that your trying to keep cool.
Plasma Burn In - No Wurries
by robbo444 - 7/7/07 8:33 AM In reply to: Plasma Burn in?? by TeezerHiya,
I have an Xbox360 an bought the panasonic TH-42PV70, sometimes i'll leave a game on pauze for 10 or 15 minutes and i have no burn in, not a trace. Go buy one and have fun playing with your ps3, you won't regret it, as long as you dont leave a still image for a couple of hours you won't have burn in on this panasonic.
Regarding Plasma Burn in??
by aztek - 7/7/07 12:51 PM In reply to: Plasma Burn in?? by TeezerThis advice may be a touch late, but it is based on actual experience.
Quite some time ago purchased a 42" Samsung rear projection TV. This was the first of the slim profile models, 11" deep. It took a mere 2 months for the channel guide to burned in and was very noticeable. Despite the extended warranty I had purchased, the store (Best Buy) washed their hands of it, stating I must have caused it by leaving the channel guide on continuously. Despite proving that the channel guide automatically shut-off after 90 seconds.(well below the 23 minutes of continuous static image the instruction book warned of) both the store and Samsung would not even return any further calls or emails. I was left High dry. Several of my friends had bought Plasmas - all of them had burn-in occur to different levels. 2 had Samsung and 3 had Panasonics. In all three cases Panasonic replaced the TVs immediately, Samsumg nothing again - either did the stores.
As luck would have it my television finally and completely failed a few months later, and I replaced it with a DLP version by Samsung - under the warranty the replacement must be by the same manufacturer. The DLP is immune to burn-in and the picture after 3 years is still very good. This version is slightly deeper (13") than the slimmer versions today. And they have superior picture quality in comparison. The only issue with DLPs, to my knowledge, is that one must use a UPS to ensure the fan is not effected by sudden power outages.
Other than that the colours and blacks on todays versions are superb. And while they may not be as sexy as their more expensive counterparts I consider them to be better value for the money that the others. Oh and by the way, while the picture on my Samsung is very good, the sounds is crap, and once again I had to fix it myself by adding a sound system. I would not recommend Samgsung, but I would recommend looking at DLP.
Good luck
Plasma burn-in
by forkboy - 7/7/07 12:54 PM In reply to: Plasma Burn in?? by TeezerI own neither a plasma or lcd television (the horror of unemployment!) and I notice there seems to be plenty of difference of opinion so I'm jumping in with my own two-cents.
Personally and solely based upon my own opinion I believe plasma to provide a better picture quality over LCD. Much has been made over the past year or two about plasma and burn-in issues and the manufacturers have apparently done much to address this issue with technology. I cannot personally speak to the issue of burn-in with plasma or LCD, but there is another option for plasma screen owners that I don't believe everyone is aware. (this may also apply to LCD screens, but I have had some in-store and at-friend's-home experience with the plasma units)
Often the manufacturers (and stores displaying units) set their televisions to settings that are meant in emphasize brightness, contrast and colour depth/saturation. Often this setting is way over the top, but makes the viewer believe it's a great picture. Changing the various possible settings to lower levels (and in effect returning the picture to a more natural viewing state) should also help reduce the likelihood of possible burn-in.
This information might be found at Consumerreports.org and I know I've read it elsewhere (over time) on this website as well.
Hope it helps.
buy a DLP
by Mike MacFarlane - 7/7/07 3:25 PM In reply to: Plasma burn-in by forkboyBuy a DLP for gaming, i have a 58" 1080P set, HP MD5880n, it has a 13,000:1 contrast ratio and it had the best picture out of all the TV's at Bestbuy and they had pioneer elite LCD's and Plasma, i have a PS3 hocked up to mine and im so happy with it.
does it really look good? CR are marketing issue
by gus738 - 7/8/07 12:10 AM In reply to: buy a DLP by Mike MacFarlaneso your saying your tv looks good ok get close to it say 6ft or move a lil bit to the side and see if it doesnt get dim, go check out the new pioneer PDP-5080 and let me know if you really think ur dlp is better lol, as for the CR (contras ratio) its markting scheme however in plasmas it seems to be as close as real as the specs (cr numbers) goes.
MANUFACTURER'S CONTRAST RATIO'S TEND TO BE EXAGGERATED,,,,
by Riverledge - 7/8/07 2:13 AM In reply to: does it really look good? CR are marketing issue by gus738AS THERE IS NO ABSOLUTE STANDARD for measuring them. Please don't confuse new-comers who may not know what CR stands for other than "customer relations."
riv.
great info forkboy! very true and those settings are called
by gus738 - 7/8/07 12:13 AM In reply to: Plasma burn-in by forkboygreat post very true and those settings are what we call "torch mode" basicly it adds up either vivid mode or dynamic
Better question
by Retheesh - 7/7/07 9:44 PM In reply to: Plasma Burn in?? by TeezerPerhaps we should ask a better question here. Will "Burn-In" occur if someone were to leave their PS3 or other console "ON" and in "Continuous Pause" for a few hours?
Now, if there are Plasmas out there that don't have such an issue, then please post the manufacturer and model number. Remember: not all TV sets are made equal, so not all TV sets have built-in protection against burn-in.
All I can recommend is searching for a TV set that has some kind of Burn-In Prevention feature like the pixel thing or going blank after a few minutes of still picture. I don't know the features' name, though.
I cannot answer this since I have not owned HD sets. But my rear-projection TV has already suffered such a fate. So I do know how Teezer feels.
reply to better question, good comment
by gus738 - 7/8/07 12:08 AM In reply to: Better question by Retheeshwell plasmas now in days (middle to higher end tvs) are capable of handling still images for serveral hrs before burn in. Most tvs now have pixel shift which moves the pixel and to the eye it makes the burn in gone, theirs also a white flush kinda feature which also flushes the burn in. guys pay attention to the new pioneer 8th gen plasmas. The 720p regular and elite editions are already out and the 1080p will be out in aug-sept
