Burn-in leaves a distinct 'burnt in' mark on the TV screen, and greatly ruins the viewing experience on a high-end television set that you have paid a lot of dollars to purchase.
So, what exactly is this burn-in, and how do you fix it? Moreover, can it simply be prevented? It would be comforting for you to know that this is mainly a problem that was faced by plasma TVs when they had just started coming into use.
The models that are available today do not face this problem anymore, as the manufacturers have figured out a way to combat this occurrence.
What is Burn-In?
The phosphor-based screen technology used in plasma TVs is similar to that used in old tube TVs and older CRT-rear projection TVs. The downside of this technology is that if an image is allowed to sit on the screen for an extended period of time, it ends up leaving a ghostly trace of itself behind.
This occurs due to the uneven wear on the phosphors inside the TV, and this is known as burn-in. Needless to say, it is a damaging and limiting effect that potentially ruins the viewing experience in its entirety.
Preventing Burn-Ins in Plasma TVs
Now, even though manufacturers have taken steps to counter this problem from arising, there is still a distinct possibility that it may crop up. Analysis of viewers' comments and reactions has also showed that by leaving a normal widescreen channel on all night, this problem can be avoided.
Some people suggest that if you record some bright static on a VCR and play it for 24 hours, all traces of an after image can be gotten rid of. There are a few other repair options that can be made use of as well, but these are just based on the comments of people gathered across various forums. There is no proof that these methods will effectively work.
Manufacturers have certainly done their part in helping to get rid of burn-in. Screensavers that are available on most TV sets play this role to perfection. Some other techniques like 'pixel shifting', 'pixel wobbling', and 'pixel orbiting' are ways to reduce the risk of burn-in.
These techniques shift the pixel on the screens slightly, at regular intervals. This prevents the bright pixels from creating an after image at one particular spot. The change of the pixels is so small and subtle that the viewer notices nothing at all.
More and more methods are being developed by plasma TV manufacturers as burn-in fixes. This is not such a serious problem anymore, and manufacturers have realized what they need to do about it.
There is still a slight chance that it may bother you, but if you know what to do you can enjoy viewing your plasma TV for many years to come without having to worry about a burn-in.
