I am thinking about replacing my old sony 32 with the Pioneer PDP-436XDE , i have been put off by screen burn , can some one tell me how Screen Burn starts and can you Avoid this problem ?

Thanks
 
My i ask all you pioneer owners , did you have to burn your screen in for around 300 hours ie turn the colour down ect or just use as normal

I am almost 100% sure of getting a pioneer plasma

I ran mine at a lower contrast and brightness etc for the first 200 hours and never had a problem they are cracking screen. Which pio screen are you looking at getting?

I am thinking of getting the PDP-436XDE or waiting for the new model in June with the new higher res screen , as the rest of my home cinema is also Pioneer :)

what are the refresh rates on the pioneer like ie watching fast moving objects do you get bluring ?

Found this which was a good read on screenburn , bit of a mouth full :)

So, how do you prevent burn-in on your brand-new plasma TV screen?

(1) Some obvious advice: Do not leave static images on your plasma TV screen for more than an hour. Turn off your unit when you are not watching it. Do not pause DVDs for more than 20 minutes at a time.

(2) Know that plasma screens are more prone to burn-in during their first 200 hours of use. When phosphors are fresh, they burn more intensely as they are ignited. This means that relatively new plasma display TVs are prone to "ghosting", which occurs when on-screen images appear to stay on the screen belatedly. This is a function of the high intensity with which new phosphors "pop," and this phenomenon usually "washes out" on its own, as the screen displays subsequent images. Displaying a bright, or moving snow image (as with a DVD or VCR with no input) will "wash" a ghost image from the screen in most cases. Many plasma manufacturers have installed anti-burn settings, which are monotone gray or snow screen settings which recalibrate pixel intensity levels uniformly - thus eliminating any image retention (ghosting). It is a good idea to run this type of program after the first 100 hours or so.

(3) Adjust the CONTRAST setting at or below 50% on your new plasma TV. These days most plasma TVs are preset to either peak or very high contrast (also called picture setting on many TVs). This forces phosphors to glow more intensely, which decreases the length of time necessary for burn-in to occur. Our advice is to reduce the contrast setting to 50% or less for the first 200 hours of use. And, be sure to avail yourself of your plasma's anti-burn-in features.

(4) Some plasma televisions burn-in more easily than others. In my experience, AliS type panels -- the ones utilized by Hitachi and Fujistu -- seem more readily given over to problems with burn-in. As well, be more wary of the 2nd and 3rd tier brands as their technology is usually not as up to date as some of the better 1st tier brands.

(5) When displaying video games and other content which have static images, use your burn-in protection features like power management settings, full-time picture shift (both vertical and horizontal), and automatic screen-saver functions. Check your Owner's Manual for further information.

(6) Realize that quality matters with burn-in as with everything else. Purchase a plasma display that has really good scaling, so that you can watch 4:3 TV programs in widescreen comfortably. It is better not to display black bars on your TV screen for prolonged periods of time (especially in the first 200 hours), so you are probably better off watching most everything in "full screen" mode. This should not be much of a problem todays selection of widescreen HDTV and DVDT content.

Also, higher quality TVs tend to be more resistant to burn-in -- though not entirely immune to it. Of the plasma displays I've owned and/or tested extensively, NEC, Sony, Pioneer, and Panasonic seemed least prone to burn-in once the plasma screen was properly broken in.

Note: There are some applications which are simply not well suited to plasma display technology. The static flight schedule signage at airports, for example. It amazes me to walk into an airport and see a ruined plasma display monitor hanging from the ceiling with what is obviously an extreme case of permanent burn- in. As LCD monitors have increased in size, they are being used to replace plasma displays in this types of setting.

The Bottom Line on Burn-In
Plasma TV burn-in is not an issue that should cause undue concern in the average user. With a modicum of caution, most plasma TVs will probably never have a problem with image retention. A viewer may experience temporary ghosting, but this is not cause for alarm.

For more about the life span of a plasma TV, please see the article "How Long Do Plasma TVs Last?"
 
The second question that I get from friends or family when discussing plasma TVs is, "Plasmas don’t last as long right, they burn out faster (than other television technologies)? The short answer to this question among top tier brands is, "No, plasma is the equivalent of LCD in longevity as a technology, though there is variation among brands and models".

FYI: The first question is, invariably, "Which is better, LCD or Plasma (TV technology). See our article: Plasma TV vs. LCD.

Plasma TV life span expectancy has long been a hot topic and rightly so. Most early plasma monitor models from 1999 and early 2000 have already been delivered to the electronics graveyard. Manufacturers were doing well to deliver a plasma product that fired up. An early adaptor could purchase a plasma TV that was 6" in depth, was hot enough to fry an egg on, and had fans that sounded like it was going to take off and fly through the roof - all for a modest $10,000.

However, improvements in the longevity of plasma TVs and displays have been rapidly effective. The green phosphors are claimed by some manufacturers as the reason behind the incredible increase. Lower power usage and motion adaptive anti burn-in technology are also contributors.

In fact, many plasma manufacturers boast a life span of 60,000 hours to half life! This is a longer life than a tube based television. The specification is somewhat suspect since the process of determining longevity of the product is based on deductive mathematical calculation of phosphor dissipation, and does not take into account the electronic components and the myriad of problems that can occur. Panasonic was the first to claim the 60,000 hour life span, up from a previous 30,000 just a year prior.

Within months after Panasonic announced this new life span, other manufacturers jumped on the bandwagon announcing that their plasma television is now rated to 60,000.

So how long will a plasma last? The long and short of it is that it depends upon your daily hourly usage as well as how you use the monitor. 12 to 55 years is my new short answer.

One practical example I will cite here is the Panasonic Tau units being used by video rental company, In Motion Pictures at major airports around the country. Most of the earlier Tau models have now been replaced by a newer model, but these plasma displays were used for 5 years and were the first generation of plasma displays to go a considerable distance. In Motion displays images on them from 6AM until 10PM daily (16 hours). By my estimates, these early plasma displays by Panasonic were in use by In Motion for around 30,000 hours or more. They never fail to catch my eye as I pass by in one airport or another to see if they are still in use. If they have lost some of their brightness level its hard to tell. This use equates to 18 years for a home owner that watches 3 hours television per day.

And this is the old model!

Manufacturer figures for longevity are closely guarded but I have added some here for your review:

Panasonic: States in new specifications that new plasma TVs and monitors are good to 60,000 to half life.

Sony: Now out of the plasma market. Does not list a figure for LCD lineup.

Samsung: Lists 60,000 hours for plasma lineup.

Pioneer: States 60,000 hours of use in their new 2005 models.

Sharp LCD panels: States 60,000 hour life.

For consumer use these numbers should be comforting. Plasma Displays are now about equivalent in longevity to LCDs, which typically state 60,000 hours. Consider that these figures are a great amount more than old CRTs, which regularly post life span to half brightness at 25,000 hours. Let's put these hours in perspective. The average U.S. household watches 4 to 6 hours of television per day. Staggering. Taking a mean time manufacturer stated longevity of 50,000 hours of usage, times our average 5 hours per day, calculates to over 27 years of usage.

Now, there are varying degrees of phosphor ignition along the way (the same way a CRT fades). Dissipation begins the moment you turn the set on. After 1000 hours of usage a plasma monitor should measure around 96% of its original brightness, which is barely noticeable to the naked eye. At 15,000 to 20,000 hours the monitor should measure around 80% brightness, or to state is technically, 80% of the original phosphors (gases) are being ignited.

There are steps you can take to ensure longer and better life from your plasma display panel:

1) Never leave static images on the unit. Plasma phosphors have become more resilient to burn in, but still its better to be safe. Do not leave a static image on the plasma screen for more than 7-10 minutes. This can cause a ghosting effect which will "wash" out by use. Watch the unit in full widescreen format as much as possible to avoid differentiation between the side bars of the unit. While this does not actually decrease the longevity of the phosphors it does cause an annoyance to have to play a gray static image to "erase" the temporary burn in.

2) Use Brightness and Contrast levels that are necessary for viewing - not excessive. In a brightly lit room you may need to view the plasma TV at a higher contrast and brightness, which will decrease the life of the unit. However, there are memory setting adjustments available on most recent plasma displays that allow the user to choose a memory setting to suit viewing needs. At night, or in a lower light room use lower contrast levels and extend the life. Do not use your plasma display on 100% contrast (often disguised as the picture option in the menu). In rooms with normal lighting you should not need to use the contrast setting on more than 60% of contrast.

NOTE: Plasma manufacturers routinely ship plasma TVs with the contrast (picture) setting tweaked to 80 to 100% of contrast. Therefore, you will need to make this necessary adjustment yourself.

3) Keep the monitor/TV in a well-ventilated area. The cooling system in the plasma will not have to work as hard.

4) Buy a good brand. First tier brands are typically better built and engineered and will last longer. My first question when someone tells me about a plasma that pooped out on them is, “What brand and model was it?” Most of the time, it’s an “off” brand.

5) Turn the plasma off when not in use.

6) Keep the unit out of reach of small children.

7) Do not mount the unit face down from the ceiling. (Philips are you listening?)

So how do the manufacturers know how to calculate the figures? The manufacturing facilities in Japan/Korea test plasma panels at 100% white image light and measure down from that point with meter readings. A series of mathematical deductions takes place. It takes months to find that 50% mark - between 40,000 and 60,000 hours. What a job that would be… to watch the white light…
