Plasma 'Screen Burn'


Sarnie

Recommended Posts

My 5 year old Sony plasma tv has developed a kind of 'screen burn'. Basically it seems that my sky+ menu has been left on for too long and when I watch tv the sky+ menu is kind of etched into the background like a shadow, if you get my drift.

 

Anyone know anyway of rectifying it or is it permanent damage? :blush:

if you can feed some white noise through, that should do it. I know chris used to do it with his. I think with the newer plasmas it's not as much of an issue compared to earlier models

 

I thought Mike for a minute you were on about my misses :lol:

I had this too, but mine was due to a video game being played on it a little too much.

 

As others have said, get some noise on it (ie an untuned tv reception with the black and white snow/speckles), just switch it to analogue tv and pull the aeriel out.

 

Wack up the brightness and contrast while its on that, and leave it overnight.

 

Most newer plasmas dont suffer from this as much, but they all will suffer to some degree. Its very often not "burn" either, rather image retention, which is non permanent.

 

Noise overnight with the brightness and contrast wacked up should probably do the trick.

Cheers guys. :notworthy:

 

Rather than pull the aerial out of my sky box can i not just flick to one of the AV channels not in use?

 

 

don't think you'll get white noise that way, you'll just get black or blue

Can sometimes turn that off in the settings, but its probably more hassle than pulling the arial lead out! Unless the TV is flush against the wall of course.

 

And of course you meant to say pull the arial out of the TV didnt you Liam, not the Sky box. Pulling it from the Sky box will just result in a "No Signal" type message. You want it on good old analogue terrestrial so you get the snow show :thumbs:

sounds like a few of the gas elements have burnt out dude, stick wth lcd's if you can :blush:

 

 

Why? I would take a modern day plasma anytime over an lcd. :)

 

Screen life - LCD last a lot longer

No screenburn - Which Plasma are suspectible too

Slimness- Because there is no need for gas filled or heavy glass fronts in a LCD screen

Brightness - LCD technology can generally deliver brighter pictures than a plasma

Power consumption - LCDs generally use less power than plasma TVs because they dont need to power hundreds of electrodes to stimulate phosphors.

 

To name a few ;)

Fact

Plasma TVs can present moving objects without loss of crispness or detail.Plasma technology needs only one impulse per pixel to produce an image therefore its response time is almost instantaneous

 

Fact

Plasma TVs can actually be watched from very wide viewing angles without any significant loss in colour or contrast, thanks to the fact that they emit light directly from each of their screen cells or pixels.

 

However, LCD pixels merely ‘pass on’ a light originating from a single point behind them, therefore LCD screens can lose contrast and colour if watched from angles as small as 45 degrees.

 

 

Fact

In the early days, plasma TVs were susceptible to screen burn. However, this issue has been largely eliminated thanks to greater use of built-in screen-saving systems and major phosphors improvements

 

Fact

The reality is that plasma TVs don’t necessarily use any more power than LCDs – a fact which makes perfect sense if you think about how each technology works.

 

Plasma TVs, for instance, require just a single ignition of a plasma cell to cause a pixel to illuminate. Since darkness is achieved in plasma pixels by stopping electrical current getting into them, it follows that plasma TVs need relatively little power to reproduce dark scenes.

 

LCDs by comparison run at a constant power regardless of whether a scene is dark or light, due to their use of an always-on backlight.

 

Results from an independent research conducted by the AVT.O.P. Messetechnik laboratory in Germany, showed that plasmas tend to use the same – and sometimes less – amounts of power than LCD screens.

 

 

Fact

Plasma TVs actually have a lifespan that’s at least equal to that of LCD TVs. TVs using either technology will provide at least 60,000 hours of life under normal viewing conditions before they lose more than half their original brightness. This translates to 27 years of continuous viewing for six hours a day.

 

Plasma screens can actually be made to last even longer depending on the picture settings you use. For instance, keeping the contrast low could potentially extend a plasma screen’s life.

 

 

Fact

Generally, Plasma TVs tend to be developed and built completely ‘in-house’.

 

In the early days of plasma TV, most manufacturers tended to develop their own plasma research and technology, leading to a situation where many companies now have plasma production as an integrated business model. This means that from the panels to processing, plasma screens are generally made entirely within each particular company, giving them total control over the quality of their products.

 

LCD TVs, on the other hand, are generally built by using a variety of third-party components, with all the quality assurance issues that entails. And even more confusingly, LCD TVs are traditionally ‘OEM’d’ –some companies buy them from another manufacturer and simply put their own brand logo on them. So with LCD, the name on the front of the TV screen you buy may not necessarily be the name of the company that built the main part of the product.

 

Comparison between Plasma and LCD technology

Choosing the type of flat screen that best suits your needs can be confusing, especially with so many different variables to bear in mind. To assist you in making your decision, here is a side-by-side comparison of each technology’s main features.

 

 

Contrast

Plasma= Intense blacks, realistic colours and tones

Lcd=Bright whites, greyish blacks

 

Colour

Plasma=Widest gamut of colours

Lcd= Vivid colours

 

Screen size

Plasma= Best suits larger screens

Lcd= Best suits smaller screens

 

Response time

Plasma= Best crisp, detailed motion

Lcd= Not ideal for handling fast motion

 

 

Sharpness

Plasma= Very naturalistic

Lcd= Unnatural rendering

 

Image processing

Plasma= Focuses on picture enhancement

Lcd=Focuses on countering LCD weaknesses

 

Screen

Plasma= Uses screen-savers, durable surface (eg. glass, Perspex)

Lcd= Susceptible to damage such as touching

 

Viewing angle

Plasma= Widest viewing angle without loss

Lcd= Prone to Wash Out

 

Value

Plasma= Best for big screens

Lcd= Best for small screens

 

 

 

15 Love, your go. :lol::p

Can you elaborate on that Dave... :lol::lol:

The largest plasma is 103 inch meh :yawn:

 

The largest LCD is 108 inch B)

 

Its all about BIG tvs :lol:

 

 

Would still take the plasma, find 103 inch a yawn hey. When it was released it was approx £58,000 still find it a bore? ;):lol:

 

beavis you aint a salesman for plasma tv's are ya? :lol: Id still prefer LCD over plasma B)
